Growing Broccoli in Queensland
Introducing Broccoli
Broccoli is a cool season crop. It loves the cooler winter weather. Broccoli is fairly easy to grow and with the right care, you can expect a bountiful harvest. Seeds should be planted in late summer to make the most of the cool growing season
Classic Mistakes
Don’t plant your broccoli too late. You want to make the most of the temperate autumn and spring weather. Once the weather gets too warm, your broccoli will feel stressed and may bolt to seed or only produce small heads.

Soil Preparation
Broccoli is a heavy feeder, so make sure to prepare your soil with compost and well-rotted manure. Broccoli likes a neutral soil, so if your soil is acidic, add some lime before planting. Where possible, try to let your soil rest for about a week before you plant into it.
Sowing Seed
Sow seeds in mid to late summer, so that they are ready to plant into the garden as soon as the weather cools.
Broccoli seeds are most often started in trays or pots and then transplanted into the garden once the weather cools. Cover the seeds lightly with soil and keep them moist while they germinate. Make sure they get enough light and transplant them as soon as they are big enough to handle. Broccoli become leggy quite easily if they are kept in trays for too long.
Planting
Try to plant bought seedlings as soon as possible after you get them home and remember to give them a good, deep watering to help them settle in. The trick here is to get them in when it’s not too hot or too cold. When you plant your seedlings out, add a small amount organic bone-meal to each hole. Bone-meal gives seedlings a great start and helps them to develop strong root systems to support a healthy plant.
If your seedlings have grown too long and become leggy; plant them slightly deeper that they were in the pots. This should give you sturdier plants with tighter heads.
Watering
Don't let the soil dry out. Broccoli loves water, so you’ll need to water more often during the dryer winter months.
Feeding
Feed regularly with compost tea, fish emulsion or organic fertilizer. Broccoli is a heavy feeder and the regular watering that broccoli needs can wash the nutrients out of the soil quickly.

Harvesting
The broccoli is ready to harvest once it forms firm heads. You need to pick it just before the flowers start to open. Cut off the head with a sharp knife. Some varieties form side shoots once the main head is removed. So, leave them in to harvest the smaller side shoots. The cold in some areas causes growth to slow, so it can sometimes be up to 20 weeks before they are ready for harvest.
