Description
Introduction to Hosta
Hosta, also known as the Plantain Lily, is a clumping herbaceous perennial from the Liliaceae family, native to Japan, China, and Korea. With around 40 different species, Hostas offer a wide range of unique characteristics and requirements. These hardy plants are primarily cultivated for their spectacular foliage, which comes in a variety of textures, colours, and sizes, including shades of green, blue, and grey, as well as variegated patterns with yellow, green, or white markings.
This pack features a diverse selection of low-maintenance Hostas, offering a variety of leaf shapes, sizes, and subtle colours. From broad, deep green leaves to striking patterns in shades of blue and green, these plants are a beautiful addition to any garden. Hostas thrive in cool to temperate climates and can adapt to warmer areas with proper care, making them an excellent choice for enhancing your garden.
Light Conditions and Foliage Development
When it comes to cultivating Hostas, light conditions play a significant role in maintaining the vibrant colours of their foliage. Variegated leaves, in particular, display their best colours with moderate sunlight. However, it’s essential to strike the right balance; keeping them in partial shade is crucial to prevent leaf scorching. On the other hand, providing too much shade can cause some Hostas to lose their variegation, turning entirely green as the plant stretches out in search of more light.
Since this is a mixed pack, plant your Hostas in areas that provide both part shade and full shade to accommodate their varying light needs. By choosing the right spots, you can influence the foliage colours and growth habits of your Hostas, guiding the development of your garden’s colour palette.
Where to Plant Your Hostas
Choosing the right spot for your Hostas is essential for ensuring they thrive and showcase their beautiful colours. Since you won’t know exactly which varieties you have received until their foliage emerges, planting in areas with both part shade and full shade will allow you to manage the light conditions effectively and influence how your Hostas develop.
- Blue Hostas:
Plant in full shade to partial shade. Blue Hostas develop their best colour in deeper shade, and too much sun can cause the blue tint to fade and may lead to leaf scorch. - Green Hostas:
These versatile plants can be placed in partial shade to full shade. Green Hostas tolerate a range of light conditions but still prefer some shade to avoid leaf burn. - Variegated Hostas (Blue and Green):
For variegated Hostas with blue and green tones, partial shade is ideal. This provides enough light to maintain their vibrant colours while protecting them from sun damage. - Yellow or Gold-Tinted Hostas:
Yellow or gold-tinted Hostas generally perform best in morning sun or dappled shade. This location helps to bring out their bright colours without risking leaf scorch. - White-Edged Hostas:
White-edged Hostas typically thrive in partial shade, where they can maintain their striking contrast without the leaves scorching.
Versatility in Garden Design
One of the standout features of Hostas is their versatility. These plants are perfect for adding texture and interest to shaded or partially shaded garden beds, borders, or containers. Whether used as a backdrop for more colourful plants, as a cohesive element in mixed plantings or as a focal point in a shaded garden bed, Hostas bring a calming, verdant presence that elevates the overall aesthetic of any garden space. Their lush foliage enhances the beauty of your garden, making them an excellent choice for both subtle and impactful landscaping.
When to Plant Hostas
Hostas can be planted from June onwards, but they thrive when established in early spring or late autumn. Planting during these periods allows the plants to acclimate before the intense heat of summer or the cold of winter. Early spring planting gives Hostas time to develop strong roots before the growing season and safeguards them from frost in cooler climates, while late autumn planting offers a head start before cooler weather arrives.
Planting in pots is also an effective way to prepare them for eventual outdoor planting.
Regardless of the climate, planting from June onwards provides flexibility, but timing your planting in early spring or late autumn generally ensures optimal growth and establishment.
What to Do When You Receive Hostas
Upon Receiving Your Hostas:
Upon arrival, you have two options: store your Hostas or pot them up. Both methods are great for ensuring your Hostas thrive in any climate. Follow the steps below based on your choice:
Storing
If you choose to store your Hostas, follow these steps to ensure they remain healthy until planting time:
First, inspect your Hostas to ensure the roots are healthy and free from damage. Then, soak the Hostas in water for 1-2 hours to rehydrate them before storing them. Next, wrap the roots in damp newspaper or place them in a breathable bag, such as a paper or mesh bag, filled with slightly damp peat moss or sawdust. This helps retain moisture without encouraging rot. Finally, store the Hostas in a cool, dark place such as a garage or shed. For those in cooler climates with extreme temperatures, this method is ideal for protecting your new plants before planting, preventing them from drying out and shielding them from harsh frost.
Potting
Alternatively, if you choose to pot them up, place the Hostas in containers filled with well-draining, organic-rich soil or a well-draining potting mix enriched with organic matter. Make sure the pots are at least 30 cm deep and wide to provide ample room for the roots to grow. Store the potted Hostas in a protected location, such as a covered porch or greenhouse. This is especially beneficial in cooler climates, allowing you to get a head start on their care. If needed, insulate the pots to protect against unexpected cold snaps, particularly in areas where temperatures may drop suddenly.
While it’s possible to plant Hostas in the ground during winter in tropical and subtropical climates, potting up new Hostas and storing them in sheltered areas offers better control over their care. This approach provides a stable environment for your Hostas until conditions are ideal for planting or moving them to their final location.
Planting Hostas in Pots
Hostas are incredibly versatile and can thrive in pots, whether placed outdoors or indoors. For outdoor planting, select a pot that is at least 30 cm deep and wide, providing ample space for the roots and ensuring good drainage. Use a well-draining potting mix enriched with organic matter to retain moisture without causing waterlogging. Position the pot in a location that aligns with the desired Hosta colour (refer to the ‘Where to Plant Your Hostas’ section), whether in full shade or partial shade
If you potted your Hostas during the winter, it’s now time to move them to a suitable spot that meets their growing needs. Please refer to the section specific to your climate for detailed guidance.
When growing Hostas indoors, opt for a container of similar size—at least 30 cm deep and wide—to provide adequate space for root development. Select a well-draining potting mix designed for containers to retain moisture without becoming soggy. Place the pot in a bright spot with indirect sunlight or filtered light to prevent leaf scorching. Water regularly, check the top inch of soil for dryness before watering, and maintain indoor humidity to support optimal moisture levels. Keep Hostas in a cool to moderate environment, away from drafts or heat sources, to ensure healthy growth.
Climates and Detailed Plant Care:
When selecting the right environment for Hostas, it’s important to consider their adaptability to various climates. Hostas thrive in cool and temperate regions and can adapt to Mediterranean and arid climates with careful attention. They may struggle in tropical or very hot climates due to extreme heat and humidity, so planting in these regions should be approached with discretion. You’ll find the planting requirements below to help your Hostas thrive in your specific climate.
Cool to Moderate Climates (e.g., Tasmania, Victoria, Southern Highlands):
Hostas generally prefer cool to moderate climates, thriving in regions with mild summers and relatively cool temperatures. In Australia, they are particularly well-suited to areas such as Tasmania, Victoria, and parts of New South Wales. These temperate climates provide the ideal environment where Hostas can receive partial to full shade, protecting them from excessive heat, which can scorch their foliage. For optimal growth, maintain consistent soil moisture, especially during warmer months, as Hostas prefer a humid environment and may struggle in dry conditions.
- Soil: Plant in well-drained, organic-rich soil, enriched with compost or well-rotted manure. This boosts soil fertility and aids in moisture retention, which is vital for healthy Hosta growth. Replenish the soil each spring, as Hostas thrive in soil abundant in organic matter.
- Planting Depth: Plant Hostas with the crown positioned at soil level. Space them about 30-90 cm apart to allow for growth and ensure good air circulation.
- Watering: Water moderately after planting to help the roots establish. Maintain consistent moisture throughout the growing season, especially during warm weather. Hostas prefer humid conditions, so keeping the soil evenly moist is crucial to preventing stress. Hostas are not drought-tolerant.
- Fertilising: Apply a complete fertiliser (such as 10-10-10) in early spring to encourage new growth. Fertilise again mid-season if needed, but avoid over-fertilising, as it can lead to lush, weak growth that is more susceptible to pests.
- Mulching: Apply a layer of mulch around the base of the plant to retain moisture, regulate soil temperature, and suppress weeds. Keep the mulch away from the crown to prevent rot. Refresh the mulch in spring to conserve moisture and suppress weeds as the weather warms.
- Pruning: Remove any dead or damaged leaves throughout the growing season to maintain a tidy appearance. Cut back the foliage in late autumn or early winter after the first frost. This helps prepare the plant for the colder months and reduces the risk of pests and diseases.
- Winter Care: Hostas, being herbaceous perennials, will naturally die back as temperatures drop in cooler climates. This die-back is normal, so don’t be alarmed if the plants appear dormant or wilted. The roots remain alive and healthy underground, waiting for warmer temperatures in spring to send up new growth. In cool climates, Hostas are hardy and can generally withstand frost. Apply a light layer of mulch after the first frost to protect the roots and prevent soil heaving during freeze-thaw cycles. This mulch will help insulate the roots and provide some protection against harsh winter conditions. Remove old mulch in spring to reduce the risk of pest buildup and refresh with new mulch as the growing season begins.
Mediterranean Climates (e.g., parts of Southern Australia and Western Australia):
In Mediterranean climates, such as parts of Southern Australia, Hostas can be grown successfully with some additional care. In these regions, it’s essential to protect Hostas from the harsh afternoon sun by planting them in areas that receive partial shade or dappled sunlight. This helps prevent foliage scorch during the hot summer months. Ensuring adequate moisture is crucial, so keep the soil consistently moist, especially during dry periods. Providing a humid microclimate, perhaps with the use of mulch or more frequent watering, will help the plants thrive despite the challenging conditions.
- Soil: Plant in well-draining, organic-rich soil that retains moisture effectively. If your soil lacks organic content, incorporating materials like compost or well-rotted manure is essential for enhancing soil structure and water retention. Replenish annually in spring, as Hostas flourish in soil rich in organic matter.
- Planting Depth: Plant Hostas with the crown positioned at soil level, spacing them 30-90 cm apart to allow for good air circulation and growth.
- Watering: Water thoroughly after planting to establish roots. In Mediterranean climates, regular watering is essential, especially during dry summer months, to maintain consistent soil moisture. Hostas are not drought-tolerant.
- Fertilising: Apply a complete fertiliser in early spring to support new growth. If additional fertilising is needed later, use it sparingly, as excessive fertiliser can lead to weak growth that struggles with the hot, dry summer conditions typical in Mediterranean climates.
- Mulching: Apply a generous layer of mulch in spring around the base of the plant to retain moisture, regulate soil temperature, and suppress weeds. This is particularly important in Mediterranean climates to protect the roots from drying out. Depending on the conditions, you may need to refresh the mulch in late summer or early autumn to ensure it remains effective, particularly if it has deteriorated or been washed away. Generally, you don’t need to add more mulch in winter unless the existing layer has significantly degraded or been displaced.
- Pruning: Hostas generally don’t need pruning. In Mediterranean climates, although Hostas may not die back completely, it’s a good idea to remove any sun-scorched or damaged leaves throughout the growing season. If desired, you can trim back the foliage in late autumn, but this is not essential.
- Winter Care: Typically, winters are mild, so extensive protection isn’t necessary. Remove old mulch in spring and refresh with new mulch to reduce the risk of pest buildup.
Arid and Semi-Arid Climates (e.g., parts of Western Australia, and Central Australia):
In arid and semi-arid climates, such as parts of Western Australia and Central Australia, growing Hostas requires careful attention to their environmental needs. In these regions, it’s vital to protect Hostas from the intense afternoon sun. Plant them in areas that receive partial shade or dappled sunlight to shield the foliage from scorching. Maintaining adequate moisture is key, so ensure the soil remains consistently moist, particularly during hot and dry weather. Creating a humid microclimate, through the use of mulch and regular watering, will support the plants in these challenging conditions, helping them to thrive.
- Soil: Plant in well-draining, organic-rich soil that retains moisture effectively. If your soil lacks organic content, incorporating materials like compost or well-rotted manure is essential for enhancing soil structure and water retention. Replenish annually in spring, as Hostas flourish in soil rich in organic matter.
- Planting Depth: Plant Hostas with the crown positioned at soil level, spacing them 30-90 cm apart to allow ample air circulation, which is vital in preventing heat stress.
- Watering: Water deeply and regularly after planting to establish roots. In these climates, consistent watering is crucial to keep the soil moist but not waterlogged, especially during the hot, dry seasons. Hostas are not drought-tolerant.
- Fertilising: Use a complete fertiliser in early spring to promote healthy growth. In arid and semi-arid climates, apply fertiliser sparingly, as excessive nutrients combined with heat stress can lead to weak growth. A single application of complete fertiliser in early spring is usually adequate for Hostas. Monitor the plants throughout the season, and only consider additional fertilisation if you notice signs of nutrient deficiency, such as yellowing leaves or poor growth. However, keep in mind that yellowing leaves could be an indication of other issues, such as watering problems, pests, or light conditions. Be sure to assess these factors before deciding on further feeding.
- Mulching: Apply a thick layer of mulch to help retain moisture, cool the soil, and suppress weeds. In arid climates, mulch is essential for protecting the roots from extreme temperatures and conserving water.
- Pruning: Remove any damaged or heat-stressed leaves as needed. Hostas do not require pruning, however, in late autumn, damaged foliage can be removed to tidy up the plant and reduce the risk of pests and diseases over the dry season.
- Winter Care: Hostas in arid and semi-arid climates typically experience mild winters, which means that extensive winter protection isn’t necessary. However, it’s important to ensure that the soil around the plants remains stable. Apply a light layer of mulch after the first frost to help retain soil moisture and regulate temperature fluctuations. This will protect the roots and prevent extreme soil temperature changes. Even though Hostas do not need heavy winter protection, maintaining soil health and moisture levels will help prepare them for the next growing season.
Tropical and Subtropical Climates (Parts of Queensland, Northern Territory, Northern New South Wales)
Hostas aren’t ideally suited for tropical or subtropical climates due to their preference for cool to moderate conditions. The fluctuation of temperatures and high humidity in these regions can cause stress, potentially decreasing the plant’s overall health. However, if you wish to grow Hostas in tropical or subtropical areas, additional care is required. Plant them in shaded areas that receive dappled sunlight to prevent them from becoming leggy while providing shelter from extreme heat. When watering, aim to water underneath the foliage, which can be achieved by placing potted Hostas in baths or, if growing in the ground, ensuring that the foliage remains dry. This practice helps prevent pests and diseases that thrive in wet conditions.
- Soil: Plant in well-draining soil enriched with organic matter to retain moisture while preventing waterlogging. Incorporating compost or well-rotted manure helps maintain soil fertility, or you can opt for soils that already offer these qualities. Replenish annually in spring, as Hostas flourish in soil rich in organic matter.
- Planting Depth: Plant Hostas with the crown positioned at soil level, and space them 30-90 cm apart to allow for air circulation. This is crucial in tropical and subtropical climates to reduce the risk of fungal diseases.
- Watering: Water generously after planting to help the roots establish. During the dry season, consistent watering is essential, but always ensure good drainage to prevent root rot. Watering in the morning is recommended, as it helps prevent foliage from staying wet overnight, reducing the risk of disease. Hostas are not drought-tolerant.
- Fertilising: Use a complete fertiliser in early spring to support new growth. In tropical and subtropical regions, fertilise sparingly and avoid excessive nitrogen, which can make the plant more susceptible to pests and diseases. A single application of complete fertiliser in early spring is usually adequate for Hostas. Monitor the plants throughout the season, and only consider additional fertilisation if you notice signs of nutrient deficiency, such as yellowing leaves or poor growth. However, keep in mind that yellowing leaves could be an indication of other issues, such as watering problems, pests, or light conditions. Be sure to assess these factors before deciding on further feeding.
- Mulching: Apply a thick layer of mulch to help retain moisture, regulate soil temperature, and suppress weeds. In tropical and subtropical climates, mulching helps create a more stable environment for the roots by buffering temperature fluctuations.
- Pruning: Remove any damaged or diseased leaves promptly to prevent the spread of fungal infections. In late autumn, prune back the foliage to tidy up the plant and reduce the risk of pests and diseases over the humid season. While Hostas do not require regular pruning, this occasional maintenance helps keep the plant healthy, especially in tropical and subtropical climates where humidity can encourage disease.
- Winter Care: Hostas usually die back in cooler climates, but in warmer regions, they may retain some foliage while entering a period of reduced activity. Even in these warmer climates, encouraging dormancy by reducing watering and trimming tired foliage can benefit the plants. Tropical and subtropical climates typically don’t require winter protection; instead, focus on maintaining healthy soil and refreshing mulch to prepare for the next growing season.
Dividing Hostas
Hostas can be divided every 4-5 years to rejuvenate the plant and control its size. The best time to divide Hostas is in early spring as the new shoots emerge or in late autumn when temperatures cool down. Carefully lift the entire plant from the ground or container and separate the clumps with a sharp knife or spade. Each division should have at least one shoot and a healthy portion of roots. Replant the divisions immediately or store them over winter if preferred.
Storing Divided Hostas Over Winter
For those opting to store them over winter, it’s crucial to do so properly to keep them healthy. Begin by shaking off excess soil from the roots and inspecting them for any damage. Trim away any unhealthy parts to maintain the plants in good condition.
If the roots seem dry, soak them in water for 1-2 hours to rehydrate. Next, wrap the roots in damp newspaper or place them in a breathable bag filled with slightly damp peat moss or sawdust. This will help retain moisture without causing rot.
Place the wrapped Hostas in a large container or box. You can also use a plastic bin with ventilation holes to allow for airflow. Store the container in a cool, dark place, such as a basement, garage, or shed, where temperatures remain between 1°C and 10°C (34°F to 50°F). This environment keeps the Hostas dormant and safe from freezing.
Periodically check the moisture levels of the wrapping material. If it starts to dry out, lightly mist it to maintain slight dampness. When spring arrives and the risk of frost has passed, replant the divided Hostas in their permanent location. Be sure to prepare the soil with compost or well-rotted manure to provide the necessary nutrients for healthy growth.
Replanting Established Hostas After Division: Key Considerations
Replanting established Hostas is similar to planting them when new but with a few key differences. You’ll need to accommodate the larger root system by digging a bigger hole and carefully spreading the roots. It’s also important to inspect the roots for any damage and trim unhealthy parts. Established Hostas may experience more transplant shock, so pay close attention to watering and soil conditions to help them re-establish. Finally, mulching is crucial to maintaining moisture and protecting the roots during this transition.
Note: Customers should follow the instructions in their climate section but consider these recommendations specifically for replanting established Hostas.
Managing Pests and Diseases
Protecting Hostas from pests and diseases is crucial to maintaining their health and appearance. Slugs and snails are common pests, particularly in humid and sub-tropical climates, and can cause significant damage to the foliage. Regularly check for these pests and use natural deterrents like beer traps or crushed eggshells to keep them at bay.
Hostas can also be susceptible to anthracnose, a fungal disease that appears as whitish spots with brown edges on leaves and stalks. If you notice any affected leaves, remove them promptly to prevent the disease from spreading. Additionally, powdery mildew, another common issue in humid conditions, can appear as white powdery spots on the leaves. To treat this, use a non-toxic solution such as a mixture of baking soda and water.
By staying vigilant and addressing any issues early, you can help ensure your Hostas remain healthy and vibrant.
