What is the best way to sow five-petal plum seeds?
Five-petal plum, also known as Madagascar periwinkle. It has flower colors such as white, red, blue, yellow and pink, and is planted in major gardens across our country.So how do you plant five-petal plum seeds?
1. How do you plant five-petal plum seeds?
Choose a spot with high, well-drained terrain facing south toward the sun, then loosen the soil, level it and make beds. Sow by broadcasting from March to May. After sowing, cover with fine, thin sandy soil, water thoroughly with a fine watering can, and cover with plastic film or a straw curtain to keep the soil moist; seedlings will emerge in 7-10 days.
2. How do you care for five-petal plum?
1. Temperature
Five-petal plum can still grow normally at temperatures of 35-37°C, but when the temperature drops below 15°C, growth immediately becomes slow, and below 10°C growth problems appear, and it may even die from frost damage. Therefore, during cultivation, its growing temperature should be kept at 20-30°C.
2. Light
Five-petal plum likes light, high temperatures and high humidity, tolerates partial shade, and is not tolerant of severe cold; it should be kept in good light at ordinary times.
3. Water and fertilizer
Madagascar periwinkle plants rot easily after being rained on, so places with a lot of rainfall need greenhouse cultivation, and the growing medium must drain well. For those grown entirely under artificial cultivation, fertilization should use water-soluble fertilizers of 20-10-20 and 14-0-14, applied alternately at a concentration of 200-250 ppm once every 7-10 days. When the winter temperature is relatively low, reduce the amount of 20-10-20 fertilizer used. If ordinary soil is used as the medium, a compound fertilizer can be mixed in as a base fertilizer in an appropriate amount before potting the medium. When fertility is insufficient, apply additional water-soluble fertilizer.
4. Pinching
When the seedlings grow to 3-4 pairs of true leaves, they can be pinched. The purpose of pinching is to make the plant sprout side branches and make the plant shape more symmetrical and full. Some varieties do not need pinching, such as “Qingjing” and others.
5. Pests and diseases
Pay attention to invasion by pests and diseases such as phytophthora blight, gray mold, gray mold, basal rot and aphids, spray pesticides in advance, and promptly remove diseased and withered branches and leaves.
