Cauliflower is a versatile vegetable that can be enjoyed in soups, stews, stir-fries, as a steamed vegetable, in a salad, or on its own. However, this plant is a temperamental 1, requiring careful maintenance and care to yield a delicious product. See Pace 1 below to beginning learning how to abound cauliflower, a skill that takes a fair bit of dedication, love, and TLC.

1. one

   Plan to grow cauliflower in cool weather. Most cauliflower varieties require almost 1.5-3 months of consistently cool weather to mature properly. Ideally, the daytime temperature while the cauliflower is maturing volition exist around 60ºF (15.5ºC).^[1] This means that the proper planting fourth dimension depends on your climate:

   • Cool climates: If your late summer temperatures are below 80ºF (27ºC), you can institute cauliflower for a fall harvest. Start the seeds 8 to 12 weeks before the first fall frost.^[2]
   • Warm climates: If yous have frost-gratuitous winters, you can plant cauliflower seeds later in autumn, once temperatures have dropped below 80ºF (27ºC). Harvest in winter or early on leap.^[3]
   • Temperate climates: Spring-planted cauliflower is difficult to grow in nearly climates. The coastal valleys of California are the merely major exception, and can support year-round crops.^{[four] [5]}

2. 2

   Adjust to a difficult climate. Cauliflower is 1 of the about temperature-sensitive vegetables effectually. If the temperature requirements in a higher place seem hard to achieve in your surface area, you can make the job easier with one or more than of these tactics:

   • Look for "summer" or "tropical" varieties that tin handle warmer temperatures than most.
   • Wait about a calendar month later the recommended seed-starting date and purchase a transplant from a garden store.^[6]
   • Constitute a new batch every week for iv–6 weeks to see which works best.^[7]

3. iii

   Choose a growing site with at to the lowest degree six hours of full sun. Though they require absurd weather, paradoxically, cauliflower as well crave a fair amount of full sun during the mean solar day. Choose a spot for planting in your garden that receives total sun and isn't shaded by trees, alpine grass, or other crops.

   • You lot'll likewise want to make sure that your growing site has ample room for your cauliflower crop. Generally, cauliflower plants will need to exist spaced about 18-24 inches autonomously.

4. four

   First with rich, wet-retaining soil. For a skilful cauliflower ingather, the plant's growth must be completely uninterrupted. This means that the plant must receive consistent wet and have admission to sufficient nutrients as it matures. A practiced soil makes meeting both of these requirements much easier. Ideally, your cauliflower's soil should take the following qualities:

   • Loftier organic matter content. This enhances the soil's ability to agree wet.
   • High potassium and nitrogen content. Potassium and nitrogen are nutrients vital for the cauliflower's development.^[8] If these are non nowadays in the soil, information technology may be necessary to use fertilizer.
   • A pH of between six.five and seven. This "sweet" pH range minimizes the danger of a cauliflower disease called clubroot and maximizes food availability.

5. v

   Start with transplants or grow seeds indoors. Cauliflower has a reputation for being somewhat fragile. Many people start with seedlings from a local garden store to transplant into their garden. If you lot have seeds instead, institute them indoors to protect the young plants from atmospheric condition:

   • Plant each seed in its own peat or paper cup. The biodegradable container lets you lot "plant" the whole pot in your garden later without damaging the cauliflower'south roots.^[9]
   • Printing the seed about 1/iv–1/2 inch (0.6–one.25 cm) deep and encompass information technology with dirt.
   • Water regularly so the soil is moist merely not waterlogged.
   • In cold weather, go on the soil at 70º F (21º C) with bottom rut from a warming plate.^[10]
   • If yous must plant your seeds directly in the garden, plant them in rows 3 to 6 inches (seven.5 to xv cm) apart.^[11]

6. vi

   Transplant the seedling. Whether y'all grew the plants from seed or bought them from a garden nursery, you lot'll need to motion them outdoors once they accept 3 or 4 true leaves:^[12]

   • Before transplanting, move the seedlings outside for one hour a mean solar day. Gradually increase this time over the course of a calendar week to "harden off" the seedlings, adapting them to outdoor weather condition.
   • If you lot used a biodegradable container, bury the container in the basis so the soil level is even with the rest of the garden.
   • If y'all used a non-biodegradable container, remove the bulb carefully to avoid breaking its roots. Brand a small pigsty in the footing and bury the seedling up to its stalk. You may desire to brand a shallow, saucer-similar low around the seedling to help the surrounding soil retain water. Firm the soil and water the seedling. ^[13]

1. ane

   Water consistently, providing ane - i. 5 inches (2.5 - 3.75 cm) of water per week. The nigh important thought when information technology comes to growing cauliflower is that of consistency. Cauliflower plants need consistent admission to moisture and nutrients or their growth won't exist consistent. If the plants' growth isn't consequent, the last product that you eat won't accept as good of taste or texture. After planting your cauliflower plants, ensure that each receives frequent watering so that its soil is consistently clammy (but non waterlogged). This unremarkably means that the plants should be receiving roughly 1 - 1.five inches of water per week and that the wet should exist penetrating roughly six inches (15.ii cm) deep.

   • Note that rainfall tin contribute towards this watering goal. Thus, if you experience frequent rainfall, it's possible that y'all may rarely need to h2o.

2. 2

   Mulch the planting area. Once the seedlings are growing in your garden, cover the soil with a low-cal layer of mulch to aid retain moisture and regulate temperature.

3. 3

   Exist set up to protect young cauliflower from pests. When cauliflower seedlings are immature and frail, they are vulnerable to a variety of garden pests, including cabbageworm, aphids, harlequin bugs, and more than.^[14] This particularly true in cases where cauliflower is being planted equally a spring ingather, as the finish of the wintertime months usually coincide with a surge in insect populations. Some of these pests tin can interfere with the cauliflower's growth cycle - others can eat the plant to ground, ruining your crop entirely, then managing these pests at the first sign of trouble is a top concern for serious gardeners.

   • Nontoxic pest treatments include diatomaceous world, soap sprays, and cultural practices such equally decision-making humidity or introducing predator insects. Wait upwardly integrated pest management practices to observe out more.
   • Yous can also use institute-friendly pesticides, but read the label carefully. Using the wrong pesticide or applying pesticide incorrectly could damage your plants or make the vegetable dangerous to eat.
   • To prevent pests from reaching your cauliflower, try cutting old milk jugs in half and laying them over the seedlings for protection.

4. 4

   Fertilize to supplement the cauliflower's growth. If growth is deadening or you suspect your soil is depression quality, examination your soil. If your soil is relatively depression in nitrogen (N) and potassium (K), bolster these nutrients with fertilizer. Apply a fertilizer loftier in the missing food(s) every two to 3 weeks.^[fifteen] Yous may also apply seaweed extract to supply boron, an important nutrient.

   • For a big home garden, y'all can use a mixture of 5 quarts of fertilizer for every 100 feet (30.5 grand) of crop row.
   • Use a technique called side-dressing to administer your fertilizer to the maturing establish. Dig a shallow, narrow furrow parallel to each row of plants virtually vi to 8 inches away from the plants' stems. Cascade the fertilizer into this furrow, rake the soil, and so h2o. This ensures that the fertilizer can be administered in equal, constant proportions to each plant and helps minimize the danger of over-fertilizing.

5. 5

   Blanch the head to forestall information technology from darkening . Every bit the cauliflower grows, a small "head" will brainstorm to form at the center of its leaves (annotation that this is sometimes also chosen the "curd"). For ordinary white cauliflower, if this head is exposed to low-cal while it is growing, information technology will xanthous and darken. Though a darkened head of cauliflower is still edible, it is less visually appealing and will have a less-tender texture. Thus, it's important to apply a procedure chosen "blanching" to proceed the head pale and white. When the head is roughly the size of an egg, curve the plant's own leaves over the head so that it is shaded from sunlight. If necessary, use twine or rubber bands to hold the leaves in identify.

   • Trapping moisture around the head can cause the establish to rot. Confirm the head is dry before blanching, and take care not to get any water on the head while it is bound.
   • Don't demark leaves so tightly around the head that air cannot attain it.
   • Note that not-white varieties of cauliflower (like imperial, dark-green, or orangish cauliflower) practise non need to be blanched. Additionally, some varieties of white cauliflower are bred to be "self-blanching", with leaves that naturally protect the head as it grows.

6. 6

   Harvest when heads are big, white, and firm. After blanching, continue caring for the plant equally normal, occasionally removing the leaves around the head to monitor its growth and allow moisture to escape after watering. When the head is large (roughly six inches (15.2 cm) beyond), white, and firm, it is ready to be harvested. This can be anywhere from a few days to a few weeks after blanching, depending on your climate (growth is more often than not faster in hot weather). Cut the head from the base of the plant with a pocketknife, leaving a few leaves attached to protect the caput. Rinse, dry, remove the leaves, and enjoy.

   • Cauliflower can be stored in a diversity of ways. Information technology will terminal for roughly a week in the refrigerator and can be frozen or pickled for long-term storage. Alternatively, cauliflower tin as well be stored by pulling the found up by its roots and hanging it upside downwards in a absurd identify for up to a calendar month.^[xvi]

   Care for boron deficiency with seaweed excerpt. If cauliflower doesn't take access to boron, an essential food, it will brainstorm to experience a variety of unappealing symptoms. Its caput will turn brown, its leafage tips will die and its leaves will distort, and its stem may become hollow and brown. To treat this problem, boron must be introduced into the plant'due south soil immediately. Feed the plant with seaweed excerpt immediately and echo every two weeks until symptoms disappear.^[17]

   • For subsequent crops, add boron to the soil by mixing in compost or planting embrace crops of vetch or clover.^[xviii]

2. 2

   Stop clubroot by eliminating infected plants. Clubroot is a fungal infection that causes large growths on the roots of plants in the family Brassicaceae (which includes cauliflower, broccoli, cabbage, Brussels sprouts, and other plants). These root growths interfere with the plant's ability to absorb h2o and nutrients, causing it to grow asymmetrically, wilt, and eventually die. Worst of all is the fact that clubroot is contagious and can easily spread from establish to plant. To prevent a case of clubroot from ruining your entire cauliflower crop, swift, aggressive action must be taken. Pull infected plants upward past their roots and discard them (don't compost them). Exist certain to remove the entire root system - whatsoever fungus left in the ground can release spores and continue spreading.

   • To prevent clubroot from returning, use one of the following methods:
     • Amend the drainage of your soil by adding organic matter (clubroot thrives in moist environments).
     • Plant a cover crop of winter rye and till it into your soil earlier planting cauliflower.
     • Rotate your crops. Practice not institute brassicas or in the same surface area two years in a row.
     • Increase the alkalinity of your soil by mixing in hydrated lime in the fall (clubroot thrives in acidic soils)
     • Lay thin sheets of clear, structure-class plastic over infected soil during sunny weather condition. Leave in place for 1 - 1.5 months. The plastic acts equally a sort of "greenhouse", trapping the sunday's rays to heat the soil and kill the fungus.

3. 3

   Forestall blackleg by practicing crop rotation. Another common fungal disease of cauliflower is blackleg. Blackleg causes irregular greyness lesions or holes in the leaves and is sometimes accompanied by root rot. Like clubroot, this disease is difficult to care for, so preventative cures are the best bet. In particular, crop rotation is an constructive technique for reducing the chance of blackleg. Don't plant cauliflower (or another member of the Brassicaceae family) in the same location more than than ane year in a row - this gives any remaining blackleg fungus in the growing site a yr to dice off.

   • Additionally, in the outcome of blackleg, remove all plant droppings left over after a harvest. This dead or dying establish material can contain live fungi for months, leading to the re-infection of the next crop.
   • If you have whatever doubts about whether sure seeds are contaminated with the fungus or not, washing the seeds in hot water can help remove the mucus prior to planting.

Article Summary 10

Cauliflower tin exist trickier to abound than a lot of vegetables, just with the right intendance, you lot can do information technology. Offset planting when the temperature has dropped below 80 degrees Fahrenheit in late summer, since cauliflower needs two to 3 months of cool weather to mature. If you alive in a temperate climate, you may likewise be able to abound it over the winter months if the temperature remains balmy. First, add compost to the soil to enrich it and assistance it retain wet, since cauliflower plants do amend in moist weather condition. Y'all should as well plant seedlings rather than seeds, because it tin be difficult to grow the plants in their early on stages. Later on you've planted the seedlings, embrace the soil with a thin layer of mulch to manage the soil's temperature and retain moisture. Apply diatomaceous earth or another nontoxic pest command to combat aphids and bugs, which dearest to consume young cauliflower plants and tin can destroy them. As your plants abound, bend the leaves over the cauliflower heads to block out the sunlight. Lighter heads will be more tender to eat and more visually highly-seasoned.
