How to cultivate beautiful needle sunflower? What is the growing environment like?

Needle sunflower is a tropical evergreen tree species, which prefers high temperature, humidity and sufficient sunlight, and has a certain negative tolerance and cold tolerance. Drought-tolerant, barren soils, but grows best on moist, loose, well-drained, and fertile acidic soils.

Needle sunflower is generally propagated by seeding. The fruit ripens in October and November, and is sown immediately after harvest or in April of the following year, using the large-grain seed sowing method. Sow in pots, keep the potting soil moist often, and seedlings can emerge in 2 to 3 months.

In the spring of the second year, the seedlings can be divided and planted in small pots. Potted plants in the northern region, the first three years of plant shape is poor, and there is no ornamental value. After three years, the plant can be plump, planted in a medium-sized pot, and placed for family ornamentation; It can also be propagated with tillers.

Cultivation: Beautiful needle sunflower likes bright light, but it can also tolerate shade, is more resistant to drought, has strong cold resistance and adaptability, and is not too strict on the soil. As long as the acidic sandy loam soil is well drained, it can meet its growth needs.

Potted plants can be made of humus soil, peat soil, plus 1 4 river sand and perlite, and can also be potted with fine sandy soil. When potting, put a layer of coarse cinder particles at the bottom of the pot as a drainage layer to facilitate drainage and aeration, spread a layer of culture soil on it, and then appropriately put some livestock hooves and broken bones as base fertilizer, which can make it grow well.

During the growth period, organic fertilizer can be applied once a week, and its need for fertilizer is relatively small, so it is advisable to use slow-acting fertilizer. Change the pot and soil once a year in early to mid-April, and when changing the pot, you can cut off part of the old roots and old potting soil at the bottom of the pot, and replace it with new cultivation soil for planting. Due to the rapid growth of the root system, the potted plant needs to be deeper than the general potted flower, otherwise in late summer and early autumn, the roots may be full of pots, and the watering and fertilizing solution will flow out, which will affect the normal growth of the plant.

In winter, it is very heat-resistant. It can still grow normally at high temperatures above 36; It is not exposed to sunlight and is more resistant to shade.

It can safely overwinter;

Water mist is sprayed once a day during the breeding period, and diluted liquid fertilizer is applied once a month. 3. Precautions: Needle sunflower can be sown and propagated, bury mature seeds in river sand to raise seedlings, and transplant after the seedlings grow to ten centimeters.

1. Breeding environment

Cultivation of needle sunflower should use good drainage, nutrient-rich sandy soil, and put the plant in the open space to the sun, fully accept the sunlight, photosynthesis, but the summer from June to early autumn in September is too strong, to pull the shade net for the sunflower to avoid sunburn.

2. Water and fertilizer management

Needle sunflower has high requirements for environmental humidity, you can spray water mist on the plant once a day to improve the humidity of the environment, and needle sunflower grows vigorously from April to early autumn in September every spring, and liquid fertilizer can be applied once a month to make the plant grow vigorously.

3. Precautions

Needle sunflower can be sown and reproduced, every autumn from October to November, pick the ripe needle sunflower fruit, bury it in the river sand, spray water mist on the surface once a day, and keep the ambient temperature at about 25 degrees, after 3 months, the needle sunflower seeds will grow seedlings, and the seedlings can be transplanted into pots after they grow to 10 cm.
