This delicious vegetable can be a bit tricky to grow and even trickier to harvest correctly. Here's how you can ensure your cauliflower is picked at its peak.
Quick Answer
Cauliflower is ready to harvest when the heads are compact and firm, roughly 6-8 inches in diameter. Harvest in the morning when temperatures are cooler.
Understanding When to Harvest
The key to harvesting cauliflower is recognising the signs that your plant is ready. Generally, cauliflower heads should be harvested when they are firm, compact, and about 6-8 inches in diameter. If you wait too long, the heads can become loose and start to yellow.
Checking the Head Size
Keep an eye on your cauliflower heads as they develop. In the UK, you might find that they reach the ideal size from late summer to early autumn, depending on when you planted them. Use a ruler to measure the diameter if you're unsure.
Colour and Compactness
The colour of the cauliflower head is another indication. You want a head that is a creamy white without any hints of yellow. The head should also be tightly packed and firm to the touch.
How to Harvest Cauliflower
Once you've determined your cauliflower is ready, it's time to harvest. Here are the steps to follow:
- Use a sharp knife to cut the head from the plant, leaving about 2 inches of stem.
- Harvest in the morning when the weather is cooler to maintain freshness.
- Avoid pulling or twisting the head, which can damage the plant.
Post-Harvest Tips
After harvesting, it's important to handle the cauliflower properly to keep it fresh. Store it in a cool, humid place to extend its shelf life. If you're planning to store it for longer periods, consider blanching and freezing.
