What is the best month to sow sunflowers?

The sowing time of sunflowers is generally chosen in spring, and it takes about two months from sowing to flowering. If you transplant from a friend or other place, you must protect the roots and stems, water them properly after transplanting, and they will bloom in about three days. Transplanting time can be summer or autumn.

What should I pay attention to when planting sunflowers?

soil

The flowering period of sunflowers is long. No matter how big the flowers are, remember to bury them in the flower soil (decomposed rice husks and chicken manure) when planting. Then use dredge and breathable nutrient soil for planting. A good soil is to mix humus soil, farmland soil and honeycomb coal powder in one third each.

Maintenance place

The place where sunflowers are grown needs to meet the conditions of sufficient light and good ventilation. The best growth temperature is between 15 and 35 degrees Celsius. The air humidity should be above 65%. At least 6 to 8 hours of light per day will make the sunflowers bloom more and brighter.

Watering

Sunflowers like moist air and avoid waterlogging in the soil. Long-term excessive moisture in the soil will cause root rot and leaf rot. It can also cause bacterial infection. When watering, "don't water unless the soil is dry, and water thoroughly when it is." Alternate between dry and wet.

Fertilization

The main fertilizers used for sunflowers are "nitrogen, phosphorus and potassium". "Nitrogen" fertilizer mainly uses fermented bean cake fertilizer to promote branch growth. "Phosphorus and potassium" mainly uses compound fertilizer to "bury" a small amount in the shallow soil layer to promote root growth and flowering.

prune

When the sunflower plant grows to 10 cm, it needs to be pruned to shorten the branches to 5 cm in length to promote the growth of side branches, form a clustered crown, and increase the number of flowering branches. After the first batch of flowers fade, it is necessary to prune the dead flowers and top them in time to destroy the growth of fruits and increase nutrients for the second flowering.

How to care for sunflowers after planting

After the sunflowers have grown into seedlings, they need to be thinned out. Keep a few according to the size of the flowerpots, and then pull up the rest of the sunflowers and transplant them to other flowerpots.

If you want the sunflower to bloom more, you need to pluck the tops. Plucking the tops can promote branching. Generally, you can pluck the tops of the sunflowers when they grow to about 5 cm.

When planting sunflowers, do not let water accumulate in the flowerpots, just keep the soil moist, and water in the morning and evening;

Sunflowers have few diseases and pests, but they need to be fertilized once a month with appropriate application of potassium dihydrogen phosphate, which can effectively increase disease resistance and promote large, colorful flowers and continuous blooming.
