Then, they dig holes at distances of 46cm (18 inches) on the rows. After preparing the field, farmers create rows at 70-80cm (27.5-31.5inches) distance one from another. On the other hand, autumn planting will give your broccolis ready for harvesting during winter. If you plant them in spring, they will be ready for harvesting during summer. However, if you insist on sowing your broccoli seeds directly outdoors, the most suitable period to do it is probably either in early spring or in autumn. Besides, when little broccoli plants appear on the ground, they often become a feed for snails and other soil pests. First of all, broccoli seeds are tiny, and broadcast seeding will result in uneven sowing. In general, commercial broccoli farmers do not prefer to sow broccoli seeds directly in the field for various reasons.
#BROCCOLI SEEDLINGS HOW TO#
How to Grow Broccoli from Seed – How to make Broccoli seedlings Each of the four main broccoli types has different characteristics and climate preferences and are: There are four main divisions of Broccoli. If we want to achieve an average yield, our broccoli plants should mature and give heads either before or after hot weather and intense heat arrive.įirst of all, it is crucial to decide the growing method as well as the varieties of broccoli that thrive in our area. As optimum temperatures, we consider average temperatures of 10-20☌ (50-68 ℉) however, some hybrid varieties can tolerate up to 30☌ (86 ☏) for a short period. Additionally, high temperatures also cause problems, especially to heads that begin to bloom. It is sensitive to frost, and it starts to have problems in temperatures under 0☌ (32☏). The plant prefers mild temperatures to thrive and form flower-heads, which is our primary goal. The restrictive factor when growing Broccoli is always the climate. They may also rotate the crop (with plants that do not belong in Brassicaceae family), to control diseases and prevent soil from depleting. After harvesting, Broccoli growers plow and destroy the remaining of the crop. Contrary to cauliflower, each broccoli plant can yield more than one head. Harvesting can be made through hand scissors or knives and is usually performed in multiple sessions, in case growers have made continuous plantings. Time from Planting to Harvesting depends on the variety, climate conditions, and the age of the seedlings. Most commercial broccoli varieties can be harvested 60-90 days after transplanting. Fertilization, Drip Irrigation, and Weed Management are applied in most cases.
When they are ready for transplanting, they make small holes in the soil, where they plant the seedlings. They also design and build a drip irrigation system. They till the land, they remove any previous cultivation remains and weeds and integrate into the soil the basal fertilization combined with well-digested manure. As they wait for the young seedlings to grow and be ready for transplanting (usually 30 days), they prepare the field. Most commercial Broccoli growers start the crop from seeds (hybrid seeds in most cases) in an indoor protected environment.
