Everything you need to know about growing cauliflower
Growing cauliflower can be very difficult because it is a very exacting vegetable. Cauliflower is also very delicate, so every step you take in the process of growing cauliflower must be precise. The most important thing about growing cauliflower is to have soil that’s full of organic matter. All that organic matter serves two purposes in growing cauliflower. It not only provides the soil with important nutrients for the cauliflower, but also helps to hold in moisture.
The pH of your soil needs to be right at or very close to 6.5. If you need to, you can add lime to the soil to make it less acidic. Just make sure you adjust the pH level of the soil in the fall, well before you plan to plant the cauliflower seeds. It takes months to get the soil properly prepared for growing cauliflower. You’ll also need to till the soil well in the fall before planting season. It’s not a bad idea to work some more organic matter or compost into the soil when you till it. Just make sure you adjusted the pH level of the soil at least six weeks before you compost and till it.
Planting season is early spring because it’s a cool weather crop. Cauliflower thrives the most when temperatures are between 65 and 80 degrees. Start by planting the cauliflower seeds about a quarter of an inch deep in small pots. When the plants are about six weeks old, then it’s just about time to transplant them into your garden. You’ll need to make your plants hardier before you plant them by gradually increasing the amount of time they are outside. Just start by setting the cauliflower seedlings outside for a few hours, and increase the time each day until the seedlings are strong enough to survive being transplanted.
Plant your seedlings about three feet apart. Make sure you dig deep enough into the soil so your cauliflower seedlings can establish roots quickly. You’ll find that sprinkling a phosphorus fertilizer on your cauliflower right after you plant it in the garden will help it grow.
You can start harvesting cauliflowers shortly before they are fully mature to prevent gathering your entire crop in just a few days. You’ll need a very sharp knife or pruning shears to cut the cauliflower heads from the stalks without damaging them. You’ll get the best-tasting cauliflower if you harvest them first thing in the morning. It’s very important that you harvest your cauliflower before the florets start to open. If they start to open, then you’ve missed your opportunity to harvest them. The good news about cauliflowers is that they can be stored safely for up to three weeks. Just hang them upside-down and spray them with a fine mist of water once a day to keep them fresh.
After the cauliflowers are harvested, you can break up the stalk and roots and use them as compost for next year’s crop of cauliflowers.
