Sowing broccoli

Broccoli seeds are best started indoors 7 to 9 weeks before the last frost. You can also sow in the garden from April to the end of May.


Broccoli needs a lot of compost, so put a good layer in the seedbed before sowing. After the main top has been harvested, add compost or organic fertilizer to grow the side shoots. The soil should be moist but not soggy. Good drainage is necessary.

What goes well with broccoli? 

broccoli goes well next to pickles, beans, chamomile, cucumber, mint, bok choy, parsnip, oregano or spinach. But avoid strawberries, legumes and radishes near broccoli, they inhibit the growth of it.

Harvesting broccoli

If you sow broccoli in early April, you will harvest it in early July. When your broccoli head is ready to harvest, use a sharp knife and cut the head of the broccoli off the plant. Cut the broccoli head stem 5 inches (12.5 cm.) or more below the head, then remove the head off with a swift cut. Try to avoid sawing at the stem as this may cause unnecessary damage to the plant and ruin your chances for side harvesting later. After you have harvested the main head, you can continue to harvest the side shoots from the broccoli. These will grow like tiny heads to the side of where the main head was. By looking at the size of the florets, you can tell when these side shoots are ready for harvest. Simply cut them off as they become ready.

How to store broccoli?

broccoli tastes best on the day of harvest. You can keep it in the fridge (in aluminum foil) for about 7 days. When broccoli turns yellow, the taste becomes bitter.
