After reading the introduction of the "planting" of the small leaves, the dogwood (←click here for memories), I feel itchy, and I also want to have a pot of dogwood to keep it beautiful. Then let’s take a look at our “flower” tricks today.
Living environment
Light: Dogwood is a light-loving plant that can be placed in a place with sufficient sunshine to maintain.
Temperature: The appropriate growth temperature of dogwood is between twenty and thirty degrees. It has strong cold resistance and can tolerate subzero low temperatures.
Soil: Dogwood is more resistant to barrenness and has low requirements for soil, but it uses good drainage and ventilation, and pot soil rich in organic matter will help the growth of dogwood.
Watering: Dogwood is not resistant to waterlogging and the soil is too moist, which will cause root rot. Watering should be based on the soil condition, and watering should not be dry or watered.
Fertilization: The principle of "using thin fertilizer frequently" should be adopted. It is only necessary to apply fertilizer once every 10-15 days during the growing season. Compound fertilizer and potassium dihydrogen phosphate can be used alternately.
Repotting: According to the growth of dogwood, you can change the pot once every two years, and the potting soil can be changed during the period.
Pest control
Anthrax : There are two types: fruit anthrax and leaf anthrax. Anthrax mainly harms the fruit. After the fruit is infected, brown spots first appear, which then expand into irregular depression black spots. Anthrax mainly harms the leaves, and reddish-brown lesions are produced on the leaves. In severe cases, the leaves are perforated and dry.
Solution: Spray 75% baijiaqing wettable powder or 50% 1000 times the solution of 50% baijialing .
horny spot disease : Mainly harmful to the leaves of dogwood. In the early stage, irregular small spots appear on the leaves, the posterior leaf edges dry and curl, the leaves fall off, forming a large number of fallen leaves.
Solution: Continuously spray 75% phenanthrene wettable powder 500-800 times solution 2-3 times, spray once every 7-10 days.
Fruit-boring moth, Big Boat Moth , etc.: During the larvae, bite the leaves, affect the growth of dogwood, reduce the fruit, and reduce the fruit setting rate in the second year.
Leafhopper : Puncture and suck tender branches and leaves, causing drying and falling leaves
Solution: You can manually capture or install insect-killing lamps to lure and kill.
Plants are not easy to grow, so you must take good care of them once you have them~
