How to Plant Elephant Garlic for Big Bulbs

As with true garlic plants, elephant garlic plants are biennials that require two growing seasons for them to complete their cycle and produce large bulbs with cloves; however, their flavor resembles leeks more closely than it does true garlic.

To maximize the yield from your crop, conduct a soil test before planting and amend as necessary. Provide regular irrigation during the long growing season. Your plants may send up flower stalks known as scapes that sap energy away from bulbs; remove these before they start curling!

Planting

Elephant garlic (Allium ampeloprasum var. ampeloprasum), commonly referred to by its scientific name Allium ampeloprasum var. ampeloprasum) may resemble and taste similar to regular garlic but is actually more closely related to leeks than garlic. This cold hardy allium produces clove-shaped bulbs significantly larger than regular garlic with milder flavors than standard varieties – although autumn planting is recommended, it can also be planted spring.

These plants require full sun, well-draining soil with neutral to slightly alkaline pH levels and an ample supply of organic matter to improve soil structure. A soil test should be completed prior to planting as both nutrients and pH levels may need to be adjusted as soon as they’ve been planted in soggy conditions; as waterlogged conditions can lead to their roots rotting quickly in soggy conditions; adding mulch around these plants in winter or early spring can protect their roots while helping suppress weeds.

Plant the cloves six to 8 inches apart with their pointed end facing upward and cover with four to five inches of loose, organic-matter rich soil. Water the area regularly until established – however avoid overwatering which could lead to bulb rot. Once foliage turns lighter green or yellow in color it’s time for harvesting; once harvested allow it to cure for up to three weeks in cool dark place with low ambient humidity for maximum flavor development.

Care

As with true garlic, these plants thrive best when grown in full sun in well-drained soil with ample airflow and regular watering, particularly during spring when they form bulbs and require regular irrigation to produce new growth. It is important not to overwater as this can lead to bulb rot; mulch can keep soil moist while helping control weed growth; these plants don’t care much for soil pH but require plenty of organic matter and fertilizers during their long growing season.

Elephant garlic, like all alliums, can be vulnerable to disease and fungal problems, particularly white rot which commonly attacks bulbs exposed to damp conditions. If a white layer begins to appear on your bulbs’ surfaces, dig them up immediately and replant elsewhere. Fungal rot is another issue and should be watched out for during cool or wet growing seasons as dusty patches can appear around its exterior surface and develop into visible mould. If this occurs replant your garlic in another location the following year while forgoing alliums for at least 15 years in that location!

Elephant garlic produces flower stalks (known as scapes) during spring that draw energy away from its bulb, drawing nutrients towards those flowers instead of curling and blooming as expected. Scapes can be cut back before they curl and bloom to encourage more of its energy to focus on bulking up its bulb instead. Luckily, these edible flower stalks make great additions to salads or stir fries!

Harvesting

Once the foliage turns yellow or brown, it’s time to harvest your elephant garlic. Gently lift each plant, without pulling, as this may damage the bulbs and lead to their rotting. Brush away soil and trim roots down to about an inch length before curing the bulbs for storage; this process typically lasts three to eight weeks depending on ambient humidity and should avoid washing which could damage their delicate skins.

Elephant garlic typically faces few pest and disease issues, though slugs may damage young plants during autumn or spring when conditions tend to be damp. Fungal diseases and rot can also threaten wet environments – to avoid this happening it is wise to plant in well-draining soil while keeping the area clear from weeds.

Like regular garlic, biennial varieties create a large bulb during their first year and then divide into cloves the following year. However, planting garlic in fall will typically only produce harvest-ready bulbs after approximately eight months; spring planting produces one bulb or even less depending on where it was placed – exception being hardy zone 8b environments which allow perennial growth of this variety of garlic.

Storage

Once harvested, let the bulbs cure for at least a month in a cool, dry location before removing their papery skins and trimming away any roots still attached to the bulbs. Do not wash the garlic as this could compromise its integrity and shorten its storage lifespan.

As an annual biennial, elephant garlic requires two growing seasons to fully form its cloves and become functional plants. Fall-planted garlic usually forms its cloves within four months while spring planting usually remains as one large monobulb.

Cold hardy allium species like garlic require full sunlight and well-drained, organically rich soil that’s neutral or slightly alkaline in pH level. Overcrowding should be avoided by planting each 20-30 cm apart; regular weeding helps keep their root area healthy, as well as protecting from fungal disease attacks that could be attacking their roots.

elephant garlic is generally disease-resistant and lacks many pests, although slugs and snails may feed on young plants; fungal diseases may affect them when conditions become humid or excessively hot and dry. To minimize problems, soil testing should be completed prior to planting in order to make necessary adjustments regarding nutrients and pH balance; heavy clay soils require amendment with organic material for optimal growth while lighter soils might benefit from topsoil addition and frequent cultivation.
