Description

Garlic Australian White
Garlic (Allium sativum) is a member of the Alliaceae family, known for producing large, rounded bulbs with creamy-white skins, sometimes streaked with pale purple. Each bulb contains tightly wrapped cloves arranged in two to three layers. The flavour is rich, robust and well-balanced, making it ideal for roasting, sautéing, or adding depth to a wide range of savoury dishes.

Typically grown as an annual crop, garlic is planted in autumn or winter, depending on the climate. This softneck, non-bolting variety does not produce a scape and is well-suited to many regions. It thrives in areas with cold to cool winters, forming strong bulbs for fresh use and long-term storage.

Climate Suitability
Garlic White performs best when exposed to a winter chill and thrives in cool, temperate and Mediterranean climates. In subtropical regions, it can be grown with careful site selection, good drainage and airflow. To improve results in warmer areas, chill the cloves in the fridge for 6 to 10 weeks before planting. This artificial cold period helps initiate strong growth and improve bulb formation. As a softneck variety, Garlic White is generally more adaptable to warmer climates than hardneck types, making it a suitable choice where winter chill is limited.

When to Plant
Plant garlic as soil temperatures fall. In warm climates, plant in autumn for root growth before winter. In cool climates, plant by the end of June. Avoid frozen or waterlogged soil. If conditions are unsuitable, start garlic in pots and transplant later.

Soil Preparation
Choose a sunny, well-drained site with rich, friable soil. Garlic prefers a pH of 6.5 to 7.5. Add compost or aged manure and avoid excess nitrogen to prevent leafy growth over bulbs. Avoid compacted soils or grow in raised beds or mounds to improve drainage and structure.

How to Plant
Use firm, healthy cloves. Split bulbs just before planting and keep skins intact. Soaking cloves is optional, but it can help with early growth and reduce transplant shock. Use the largest cloves for planting, as these are more likely to produce strong, full-sized bulbs. The smallest interior cloves can either be planted to produce smaller bulbs or used in the kitchen. Plant with the pointed end up, about 5 cm deep. Space 10 cm apart with 15 cm between rows. Increase spacing in humid areas to improve airflow.

Apply 2 to 3 cm of loose mulch after planting. Adjust mulch thickness in humid regions to avoid excess moisture. Raised beds or containers are ideal for heavy or wet soils.

Growing in Pots
Garlic White is ideal for pots. Use a large, deep container with drainage and quality potting mix enriched with compost. Space cloves 10 cm apart and place in full sun. Water consistently, as potted garlic dries out faster than the soil. With proper care, expect a harvest in late spring to summer.

Fertilising
Before planting, apply compost or aged manure and a balanced fertiliser, such as Blood and Bone or Dynamic Lifter. Reapply lightly after foliage appears, then stop once lower leaves yellow. In pots, use slow-release or liquid fertiliser throughout the season. Always water after feeding to help nutrients reach the roots.

Watering
After planting, water lightly. Garlic needs little water until shoots appear, and rainfall is often enough. In pots, check moisture more frequently. Maintain consistent but moderate watering once foliage develops. Reduce watering when the lower leaves begin to yellow. The tops may also start to brown. Stop watering completely a few weeks before harvesting.

Mulching
Mulch helps conserve moisture, suppress weeds and regulate soil temperature. Use a loose organic mulch, such as straw or sugarcane, and keep it clear of emerging shoots. In cooler or dry climates, a thicker layer can help insulate the soil and retain moisture. In warm, humid climates, apply mulch more lightly to prevent excess moisture. Garlic dislikes weed competition, especially early on, so keep the bed clear to support strong growth and larger bulbs.

Harvesting and Storage
Garlic White matures in 8 to 9 months. Harvest when the lower leaves have yellowed and 4 to 6 green leaves remain, as each green leaf corresponds to a protective layer around the bulb. In wet climates, harvest promptly at this stage to reduce the risk of rot. In warm or dry regions, garlic may mature more quickly, so monitor plants closely.

Lift bulbs gently with a fork. Do not wash. Brush off soil and cure in a dry, shaded, well-ventilated place for 2 to 4 weeks, or up to 10 weeks in humid climates. Once dry, trim roots and stems or braid. Store in a cool, dark location. Garlic White stores well for 6 to 9 months under ideal conditions.

Bulbs are large, rounded, with creamy-white skins, sometimes streaked with pale purple. Cloves are tightly wrapped and slightly harder to peel, but perfect for roasting, sautéing and enhancing a wide variety of dishes.

Safety
Garlic is safe for human consumption but should be kept out of reach of pets, especially dogs and cats, as large quantities can be toxic if ingested. When planting, harvesting or handling garlic, individuals with sensitive skin may wish to wear gloves, as extended contact with raw cloves or garlic juice may occasionally irritate. If you have any concerns about the effects of garlic on your pets, consult your veterinarian for advice.

Harvest Time

Harvest Garlic White in summer, once the bulbs have reached full maturity. Softneck garlic typically takes around 6 to 9 months to develop, with most crops ready between 8 and 9 months, depending on climate, planting time, and growing conditions. In warmer regions where planting usually occurs in autumn, harvest can take place as early as late spring or early summer. In cooler regions where planting typically takes place during winter, garlic is usually ready in mid to late summer.

While many softneck varieties mature within 8 to 9 months, some may take up to 10 months, especially if growing conditions are cooler or development has been slow. This extended growing period allows bulbs to fully form and cure naturally in the ground.

Rather than relying solely on the number of months since planting, monitor your garlic plants closely as the season progresses. Environmental factors, planting time, and soil conditions can all influence the exact harvest window.
Planting Time

Garlic White is best planted during the cooler months, allowing cloves to establish strong root systems before warmer weather triggers bulb development. It performs reliably when given time to grow through autumn and winter, with root growth supported by cool soil and reduced humidity.

In warmer climates, plant in early autumn; in cooler climates, aim to plant by early winter. Unlike many softneck varieties, Garlic White benefits from exposure to a winter chill during its early stages. For best results, plant a few weeks before your region’s coldest period to ensure strong root growth and uniform bulb formation.

Recommended Planting Windows by Climate:
• Cool and temperate regions: March to June
• Subtropical regions: March to June — pre-chilling cloves in the refrigerator for 6 to 10 weeks before planting can help mimic winter conditions and support better bulb development
• Arid regions: March to July

The autumn equinox (around 20–21 March) is often seen as the start of ideal planting weather. In cooler areas, planting is generally completed by the winter solstice (around 21–22 June), giving the garlic time to establish before spring growth accelerates.

If ground conditions are too wet, frozen, or difficult to work with, garlic can be started in pots during the cooler months and transplanted once the soil is ready. Use a deep container with good drainage and quality potting mix. This approach supports early development and avoids delays caused by unfavourable soil.

These planting ranges are a general guide and may vary with seasonal patterns. Align your planting with local weather conditions, focusing on cool soil and reliable drainage while avoiding extreme heat or excess moisture.
Planting Depth

Plant garlic cloves with the pointed tip facing up and the flat base down. The ideal planting depth is approximately 5 cm below the soil surface, measured from the tip of the clove to the top of the soil. This depth supports strong root development and healthy emergence.

If your soil is heavy, poorly drained or prone to retaining moisture, consider planting slightly shallower, around 2 to 3 cm deep, to help prevent rot. Avoid planting deeper than 5 cm, as softneck garlic does not require the extra insulation that hardneck types may benefit from.

In raised beds or well-prepared garden soil, the standard 5 cm depth is ideal. Cloves planted too shallowly may become exposed as the soil settles, while those planted too deeply may struggle to emerge or develop properly, especially in dense soils.
Planting Width

Space cloves at least 10 cm apart, with 15 cm between rows, to ensure they have enough room to grow and allow for good airflow. Cloves can be spaced further apart, up to 15 to 20 cm, if desired. This wider spacing may be beneficial in areas prone to pests and diseases, as it improves ventilation and reduces competition between plants.
Soil

Garlic prefers fertile, friable, well-drained soil with a pH between 6.5 and 7.5. Enrich the soil with either compost or well-aged manure, and apply a balanced organic fertiliser such as Blood and Bone or Dynamic Lifter to support strong, even bulb development.

Preparing the beds a few weeks in advance allows the soil amendments to break down properly and gives the pH time to stabilise before planting. Compost and manure can temporarily lower soil pH, so test the soil after incorporating organic matter. If the pH is too low, raise it by applying garden lime or dolomite according to the product instructions.

Avoid planting garlic in heavy clay or poorly drained soils, as this can result in rot and misshapen bulbs. Improve drainage by working in organic matter, planting in raised beds, or forming mounded rows within trenches, positioning the cloves on top of the mound and covering them lightly with soil. Garlic does not tolerate waterlogged conditions, so ensuring good drainage is essential for a healthy crop.
How to Plant

Choose a sunny, open position with well-drained, friable soil. Avoid areas prone to waterlogging or heavy clay, which can lead to rot or misshapen bulbs. Garlic prefers a sheltered spot, so provide some protection from strong winds where necessary.

When planting your garlic, check that the cloves are firm and healthy. Break bulbs into individual cloves only when you are ready to soak and plant, keeping the skins intact to protect them.

Soaking cloves before planting is optional but can be beneficial. It helps hydrate the cloves, provides gentle nutrients, encourages early root development, and improves their chance of successful establishment while reducing transplant shock. Cloves can be soaked for a few hours or overnight in a weak solution of seaweed extract or fish emulsion. Once soaked, plant them promptly, as soaked cloves will deteriorate if left out for too long.
Very small interior cloves can be planted if desired, but they typically produce smaller bulbs. Otherwise, set them aside for kitchen use. Once separated from the bulb, these cloves are best used within a few weeks, as they do not store as long.

Plant cloves with the pointed end facing up at around 5 cm depth. In wetter regions, plant slightly shallower, at about 2–3 cm, to minimise moisture-related issues, ensuring the tops of the cloves sit just below the soil surface.

Space cloves at least 10 cm apart in rows about 15 cm apart to promote airflow and reduce the risk of fungal diseases. The more space between plants, the harder it is for pests and diseases to spread, as good separation reduces humidity and limits physical contact between infected foliage.

Apply mulch after planting to help conserve moisture, suppress weeds and regulate soil temperature. In cooler regions, a thicker layer (5–7 cm) of straw, sugarcane mulch or other loose organic material helps insulate the soil and protect developing roots. In hot, dry climates, a similarly thick mulch can help prevent the soil from drying out and overheating. In warm, humid climates, apply a lighter mulch (around 2–3 cm) to avoid excess moisture around the cloves, which can encourage rot or fungal issues.

For heavy or poorly drained soils, consider planting garlic in raised beds or on top of mounds to improve drainage and reduce the risk of rot. Large containers are also a suitable option, offering better control over soil conditions.
Watering

After planting, water the garlic in lightly to help settle the soil and initiate root development. Garlic does not require heavy watering at this stage, as the cloves are dormant and excess moisture can hinder sprouting. Too much water early on can increase the risk of rot, especially in poorly drained soils.

Natural rainfall is often sufficient to sustain garlic during its early stages. However, if rainfall is low or inconsistent, apply light water sparingly to prevent the soil from drying out completely until green shoots emerge.

When growing in pots, keep in mind that container soil tends to dry out faster than garden beds, particularly in warm or windy conditions. Monitor moisture levels regularly and water as needed to avoid the soil becoming overly dry before shoots appear.

As the garlic continues to grow, maintain consistent soil moisture to support foliage and bulb development. Water deeply when the top few centimetres of soil feel dry, allowing the soil to drain well between waterings. Avoid overwatering, as saturated conditions can lead to rot or misshapen bulbs. Garlic should not be planted in heavy clay soils, which retain too much water and prevent proper bulb formation. If necessary, improve the site by using raised beds filled with free-draining, friable soil, or plant in mounds.

The tops may also begin to brown at this stage. Cease watering entirely a few weeks before harvest to allow the bulbs to dry and firm up in the soil before lifting. In some cases, garlic may be ready to harvest just one to two weeks after watering stops. Use the presence of 4 to 6 green leaves as your cue. If the timing varies slightly, rest assured the bulbs will continue to mature safely in the soil.
Fertilise

Garlic requires moderate feeding to develop strong foliage and healthy bulbs. Before planting, apply a balanced organic fertiliser such as Blood and Bone or Dynamic Lifter, and gently mix it through the topsoil. These fertilisers provide a good balance of nutrients to support root and leaf development.

Once growth appears and leaves begin to form, supplement with a low-nitrogen, higher-potassium fertiliser every 3–4 weeks. Products like PowerFeed PRO SERIES Flowers, Fruit & Citrus or Seasol plus Nutrients – Fruit & Citrus support strong bulb formation and steady plant health. Always follow the manufacturer's instructions for application rates.

Feeding should be timed to support early and mid-season growth. Apply fertiliser during active growth but avoid further fertilising once the lower leaves begin to yellow and dry out, as this signals that the plant is nearing maturity and no longer requires added nutrients.

Well-aged manure and compost are beneficial for improving soil structure and fertility. However, because these amendments may slightly lower pH, it’s advisable to check the soil pH after application. Garlic prefers a pH of 6.5 to 7.5. If needed, you can raise the pH by adding dolomite lime or garden lime to reduce acidity and create a more favourable environment for bulb development.

For garlic grown in pots, nutrients leach more quickly than in garden beds. Before planting, incorporate a balanced organic pelletised fertiliser, such as Blood and Bone or Dynamic Lifter, into the potting mix to provide a steady supply of nutrients. Use a high-quality, free-draining potting mix enriched with well-aged manure and compost to support root development and retain just enough moisture. As the garlic begins to grow, supplement with a diluted liquid fertiliser every 3–4 weeks to support healthy development and bulb formation. Liquid options like fish emulsion, seaweed extract, or formulations high in potassium (such as PowerFeed PRO SERIES Flowers, Fruit & Citrus) are ideal. Always water well after feeding to help nutrients reach the roots.

Mulching plays an important role in maintaining soil health throughout the garlic growing season. Organic mulches such as straw, sugarcane mulch, or shredded leaves help conserve moisture, moderate soil temperatures, and suppress weed growth. In warmer regions, mulch also protects bulbs from excessive heat, while in cooler areas, it insulates the soil during early growth.

Avoid compacting mulch directly over emerging shoots. Keep the layer loose and airy to ensure good airflow and prevent excessive humidity, especially in areas with high rainfall. As the garlic matures, the mulch can be gently pulled back to help reduce moisture and allow the bulbs to dry slightly before harvest.
Harvest

Garlic White typically matures 6 to 9 months after planting, with most crops ready between 8 and 9 months, depending on climate, planting time, and growing conditions.

The best indicator that garlic is ready to harvest is the yellowing of the lower leaves, starting from the base and moving upward. Leaves may also brown or yellow at the tips; this is normal. For optimal storage and protection, harvest when 4 to 6 green leaves remain, as each leaf forms a protective wrapper around the bulb during curing.

In cooler or wetter climates, consider harvesting when around 6 green leaves remain to reduce the risk of bulb skins deteriorating in the ground. In hotter, drier regions, garlic may mature faster, so monitor plants closely. Harvest once the lower leaves have yellowed and 4 to 6 green leaves remain, before bulbs begin to split or lose their wrappers. Another sign of maturity is when stems soften or bend near the base, but always wait until 4 to 6 green leaves are left to ensure proper curing.

If unsure whether your garlic is ready, gently lift one bulb using a fork or trowel and assess its size and skin development. If the bulb is small or not yet fully formed, allow the remainder of the crop to continue maturing for another 1–2 weeks before checking again.

To harvest, carefully loosen the soil with a fork or trowel and lift the bulbs to prevent bruising. Do not wash the garlic after harvest; instead, shake or brush off excess soil and leave the bulbs intact. Cure in a dry, well-ventilated area out of direct sunlight for 2 to 4 weeks, or up to 10 weeks in more humid regions, until the outer skins become completely dry and papery.

Once cured, trim the roots and stems to about 2.5 cm, or braid the stems if preferred. Store bulbs in a cool, dry, dark, and well-ventilated location. Under ideal conditions, Garlic White stores well for 6 to 9 months, though this may vary slightly based on harvest timing and storage conditions.

Its excellent storage capacity is due to the firm, tightly layered skins that help protect the cloves and retain freshness. Garlic White forms teardrop-shaped bulbs with a flat base and white to creamy skins, sometimes streaked with pale purple. Cloves are arranged in two to three layers, with larger outer cloves and a few smaller ones at the centre. Although the tightly wrapped skins can make peeling slightly more difficult, the cloves are ideal for roasting, sautéing, or adding depth of flavour to sauces, stir-fries, soups, and stews.

Please note: Although Garlic White is a softneck variety and usually does not produce scapes, a flowering stem may occasionally appear in response to environmental stress. If this occurs, remove the scape early to help direct energy back into bulb development and ensure a better harvest.
