Tips for Growing Purple Sprouting Broccoli

Tips for Growing Purple Sprouting Broccoli

Purple sprouting broccoli is usually grown in the United Kingdom in order to get a harvest during the “lean” months of November to March, when there is less demand for food.

Some new cultivars are now available for harvest from late July to late October, depending on the variety. The harvest quality of these new early types, on the other hand, has not yet reached the level of classic Purple Sprouting Broccoli.

A good broccoli crop is threatened by extreme weather conditions (extra rain and/or above-average temperatures) as well as pests (pigeons and caterpillars). With the exception of excessive rain, broccoli’s adversaries can be dealt with forethought and foresight.

Benefits of Purple sprouting broccoli

This purple-sprouting broccoli variety has a delicious flavor, has a lengthy harvest season, and is exceptionally nutritious. A single serving has half of your daily need for carotenoids, as well as a lot of folic acid, vitamin A, and vitamin C.

Choosing the proper types and timing your seed planting correctly allows you to harvest your crops from the end of the previous season to the beginning of the next year’s early summer harvest.

Purple-sprouting broccoli is a tough plant that can withstand temperatures as low as -12 degrees Celsius. Growers may plant seeds in March for harvest in early winter and can plant seeds from April to mid-June for harvest in January to May.

Purple-sprouting broccoli, like other brassicas, thrives on soil that is rather heavy and alkaline in pH. It is best not to plant it in an exposed location where the wind may buffet the stems and disturb the soil around the roots.

Steps to Grow Purple Sprouting Broccoli

1. In tiny pots or multi-cell trays, sow the seeds, using a high-quality multi-purpose or loam-based seed and cuttings compost to start the plants. When the seedlings are grown enough to handle, prick them out and transfer them into single 9cm pots, being sure to water them well.

2. Remove big stones, debris, and perennial weeds from the soil by turning it over with a fork. The addition of bulky organic matter is required in light soils, but it is also beneficial in heavy soils since it improves moisture retention and texture. If your soil is acidic, you may need to apply lime to balance it out. Brassicas do not like loose soil, so firm it gently with your foot to avoid damaging it.

3. When the plants are 7-9 cm tall, they are ready to be transplanted. Make sure to thoroughly water them before taking them from their pots. Space them 50–60 cm apart, with a similar interval between each row. After planting, re-water the area and firm each rootball into place. If you want enough broccoli to serve a family of four, you’ll need to grow six plants.

4. To prevent competition, keep the soil wet at all times and eliminate weeds as needed. If growth is sluggish and the stems of purple buds do not form, a liquid feed may be used to urge them to appear. Make sure to cover the area with fleece or netting to discourage insects and birds from getting in.

How to Take Care of Purple Sprouting Broccoli

Purple sprouting broccoli grows best when it is well-fed with a nitrogen-rich fertilizer, which is particularly important during the early stages of development. Up to the end of October, a once-a-month application of Growmore fertiliser will be adequate to maintain an appropriate amount of nitrogen. The addition of fish, blood, and bone (a handful per plant) in September will help to maintain the other nutrient levels in the soil.

Keep the plants well watered when the weather is hot and dry. Every month, look at the plants and remove any yellowing leaves that have grown because they will only make you sick.

Soon after you plant your purple sprouting broccoli, you’ll need to decide on the degree of pest control you’ll use to protect your crop. Birds, cabbage white caterpillars, and the cabbage root fly are all potential threats. It is hard to anticipate whether or not a site will be affected by these pests—some areas will be affected, while others will not.

All of these things may be avoided by covering your crop with mesh. In this essay on bug mesh netting, we will look at the many alternatives that are typically available.

How to harvest Purple sprouting broccoli

When the weather is warm, purple sprouting broccoli is prone to bolting, which is when the blossoms open prematurely in an effort to generate seed. The temperature of the soil in the United Kingdom is what causes bolting under warm weather conditions; it is not the temperature of the air.


If you want to prevent this, mulch your soil as soon as possible in the growing season. It is possible to reduce soil warmth and moisture by using a layer of cardboard on top of organic materials such as grass clippings or wood chips.

Purple sprouting broccoli is a tall plant that, when fully grown, may need assistance from a post to keep it upright. This should be done in October before the harsh winter winds crush them.

Harvesting purple sprouting broccoli is a straightforward process. The core spear will develop initially, followed by multiple lateral shoots, until the whole structure is completed.

Harvesting Purple Sprouting Broccoli Plants

Take advantage of the flower shoots’ maturity before harvesting them, but before the blossoms have really opened. Make a clean cut through the center spear with a sharp knife first, since this will stimulate the side shoots to grow more rapidly. Picking the sideshoots on a regular basis will help to lengthen the cropping time.

Cut away the primary floret as soon as it appears to encourage the formation of side stems that will eventually grow into secondary flowers. When they reach 6 to 8 inches in height, harvest them (15–20 cm). Continue to look for fresh side shoots every few days to see if any have appeared.
