The mistake almost everyone makes is waiting for a head to reach the size they see in shops. Head size is set by the plant, not by patience: a plant that built a modest canopy will make a six inch head and then start to loosen, and waiting will only turn a good six inch head into a poor one.
The test is texture. Press the curd gently with the flat of your hand. A ready head is firm and resists, with a smooth, tight surface and no visible separation between the sections. As soon as it gives slightly, or the surface begins to look grainy, it is at its peak and going backwards.
Typical home garden heads run four to eight inches (10 to 20 cm) across. Summer types are usually smaller and faster; autumn and overwintered types larger and slower.
| Sign | What it means | Action |
|---|---|---|
| Smooth, dense, firm to the palm | At its peak | Cut now |
| Surface just beginning to look grainy | Starting to rice | Cut today |
| Sections visibly separating | Loosening | Cut and use immediately |
| Yellow or bronze surface | Sun exposure, not over-maturity | Cut; trim the colored layer if you want |
| Buds elongating, showing yellow | Beginning to flower | Only the stem and small florets are worth keeping |
| Small but firm on a small plant | A buttoned head | Cut it; it will not grow further |
In warm weather, check every two days once the curd is expanding. Three days of neglect in a heatwave is enough to lose a head that was perfect on the day you last looked.
How to cut
Cutting is straightforward, but doing it in the cool of the morning and keeping the wrapper leaves on makes a real difference to how long the head stays crisp. A head cut in the afternoon sun is already warm and limp before it reaches the kitchen.
- Cut early in the morning Field heat is what shortens storage life. A head cut before the sun is on it comes in cold and firm and keeps several days longer.
- Cut the stem below the wrapper leaves Take a sharp knife and cut the main stem an inch or two (3 to 5 cm) below the lowest wrapper leaf, so the head comes away with a collar of leaves attached.
- Leave the wrapper leaves on Those leaves protect the curd from bruising and stop it drying. Trim them to an inch (2 to 3 cm) above the head and leave them until you cook it.
- Turn the head over and check Slugs and caterpillars shelter between the wrapper leaves and the curd. Look before it goes in the basket, not in the kitchen sink.
- Pull the whole plant afterwards Once cut, the plant has nothing more to give. Pull it, knock the soil off the roots and look at them: knobbly, swollen roots mean clubroot and change what you plant there next.
Cut all the leaves off level with the top of the head if you are packing several into a box. Long leaves bruise the curd of the head next to it.
Second cuttings and side shoots
A cauliflower is not a broccoli and does not reliably produce a second crop. Some plants, particularly summer types cut early with plenty of leaf left, will push out small side shoots from the leaf axils over the following weeks. These are worth eating but small, and they are a bonus rather than something to plan around.
If you want to try for them, cut the head high, leaving as much stem and leaf as you can, keep the plant watered and give it a light nitrogen feed. If nothing appears within three weeks, pull the plant and free up the ground.
Do not leave a spent plant standing all season on the chance of side shoots. It occupies space, harbors aphids and caterpillars over winter, and keeps brassica soil-borne diseases active in that spot.
Keeping the crop after cutting
Cauliflower does not store for long in any form. It wants cold, damp air and it wants to be away from ripening fruit, since the ethylene those give off browns the curd quickly. The realistic plan is to eat it within a week, freeze what you cannot, and stagger the sowings so heads do not all arrive at once.
| Method | Preparation | How long |
|---|---|---|
| Refrigerated whole | Wrapper leaves on, loosely bagged, stem down | One to two weeks |
| In a cold shed or cellar | Whole, wrapped in damp paper at 32 to 39F (0 to 4C) | Up to three weeks |
| Hung by the roots | Whole plant lifted with roots, hung in a frost-free shed | Two to four weeks |
| Frozen | Broken into florets, blanched three minutes, cooled and dried | Ten to twelve months |
| Pickled | Small florets, packed in a spiced vinegar brine | Several months |
| Cut florets, refrigerated | In a sealed box with a sheet of paper | Three to four days |
Keep cauliflower away from apples, pears, tomatoes and bananas in storage. Ethylene from ripening fruit turns a white curd brown and speckled within days.
Spreading the harvest
The single most common complaint about cauliflower is that every plant heads in the same fortnight and then the season is over. That is not bad luck; identical plants sown on the same day into the same bed will do exactly that.
Spread it deliberately. Sow in two or three batches a fortnight apart, and use more than one type so that days-to-heading differs as well. Planting a few in a shadier or cooler part of the plot pushes them back by a week or so more.
- Sow in batches a fortnight apart Three sowings two weeks apart from one packet turns a single glut into six weeks of cutting, for no extra work.
- Mix early and late types Combining a 75 day type with a 100 day type in the same sowing spreads the harvest by three or four weeks on its own.
- Use the cooler corners of the plot Plants in partial shade or on the cold side of a hedge head noticeably later than the same batch in full sun.
- Freeze the overlap on the day you cut When two batches do collide, blanch and freeze the surplus straight away rather than trying to hold whole heads in the fridge.
What to note at harvest
Harvest is the point at which every earlier decision has finally shown its result, which makes it the most useful moment of the year to write things down. Ten lines noted while you are cutting will shape next year's sowing dates and spacing far better than anything remembered in spring.
| Record | How it changes next season |
|---|---|
| Date cut and days from sowing | Sets your real interval, which beats any packet figure |
| Head diameter and firmness | Small heads point back to a check or to tight spacing |
| Whether it riced or loosened | Tells you to move the sowing so heading avoids the heat |
| Condition of the roots when pulled | Clubroot found now decides the rotation before you plan the bed |
| Which plants headed first | Identifies the warm and cold ends of the plot for staggering |
| How long each head kept | Shows whether cutting in the morning is worth the effort in your conditions |
Note the position of any plant that headed badly, not just the fact that it did. Repeated failures in the same corner of a bed are almost always about drainage, shade or a soil problem in that spot.
