What about ornamental sunflowers? Introduction to common varieties

Sunflowers always symbolize a positive attitude toward life, turning to follow the sun. Facing the sunlight, optimistic and strong. Many flower lovers like them, and besides these symbols, they look beautiful. Sunflowers are also classified and can be divided into several types. Let's learn about the cultivation methods of sunflowers below.

Cultivation methods for ornamental sunflowers:

The optimum germination temperature for ornamental sunflowers is 22 to 30°C. After sowing, they can germinate in 5 to 7 days. When 4 to 6 true leaves appear, transplant once. When the seedlings are about 10 cm tall, plant them out, and cover the roots with soil to stabilize the roots and prevent lodging. After the plants are established, apply topdressing; both organic fertilizer and chemical fertilizer give ideal results. After the flower buds form, it is advisable to water more to keep the soil moist.

1. Dwarf sunflower is 30 to 40 cm tall, with a flower diameter of 10 to 17 cm. The single petals are bright golden yellow, and the flower center is black. Generally, it can bloom 50 to 55 days after sowing, suitable for pot cultivation and flowerbed planting.

2. For seedling raising, use seed propagation, generally sowing in April. The optimum germination temperature is 15 to 18°C. You can sow in a shallow pot or shallow box. The medium should be loose, have good water retention, and be sterile. Sowing is best done by dibbling, with 2 seeds per hole. After sowing, cover with 1 to 2 cm of medium to maintain the humidity needed for germination, increase stability during the seedling stage, and reduce the occurrence of seedlings with shells. Generally, germination occurs 7 to 14 days after sowing. After emergence, pay attention to ventilation and cooling, control humidity, and gradually expose them to light.

3. Planting out and care: When the seedlings have all emerged, thin them out gradually, leaving 1 plant per hole. When the seedlings are 7 to 8 cm tall, they can be planted out. The potting soil is best if it is sandy soil rich in humus and well drained. When planting out, apply sufficient base fertilizer at the bottom of the pot. When digging up the seedlings, carry as much soil as possible and damage the roots as little as possible so the plants recover faster. Dwarf sunflowers like a sunny and warm environment, and are not tolerant of shade or cold. During the growing period, fertilize once every 20 days, but before flowering, apply 2 to 3 times of dilute phosphorus and potassium fertilizer. Always keep the soil moist; especially in summer during high temperature and drought, water promptly. To make the terminal bud of the main stem grow robustly, remove the axillary buds. For those with slightly taller stems, set up supports to prevent wind lodging. During flowering, perform artificial pollination to increase the seed-setting rate.
