GROWING AT HOME
Soil for Planting
Ideal conditions for growing broccoli are luminous, fertile and hydrated soil, sparsely acidic in nature. Use 2-4 inches of a bloated layer of manure, before sowing. In order to plant the seeds in spring, relocate the seeds 2-3 weeks earlier, before the final frost date of spring. The seeds require at least 10 days for maturing. For seeding in the fall, you would do better to do so at least 85 -100 days before the average fall frost.
In case you are planning for your seedlings, plant them about 7-9 weeks earlier to the tentative final frost. Ideally the seeds should sprout up within 4-5 days. Once the seeds vegetate, You should relocate the pots in an illuminated spot, having an average temperature around 60-65 F. Ideally you must not leave the soil wet, but hydrated. In order to avoid untimely heading, before relocating the plants, it is crucial to ensure the seedlings are in proper size: approximately 6 inches in height, bearing 2-4 real leaves. Before relocating the plants, it is important to harden them at for a week. The young plants should be set at least 1-2 inch deep in the garden. You must provide 1-2 foot gaps and 2-3 apart in rows to avoid tiny headings.
Consistent hydrating of soil is very vital, especially if there is drought. Even though a few varieties of broccoli can withstand heat, all of them need watering. However, avoid wetting the developing heads.
Temp and Humidity
Soil, having a temperature below 40 F is best for broccoli.
- After transplanting, fertilize after 3 weeks, and you do not need to cultivate.
- Mulching the soil is vital to remove weeds and lower the temperatures.
Pest and Pesticides
