How to maintain geranium in summer: ventilation is very important, reduce nutrient consumption, wate

Summer is already on the way, and the most troublesome problem for flower lovers is how to maintain geranium in summer. In this paper, from a flower friend who has many years of experience in Pelargonium cultivation, some opinions on Pelargonium summer, to provide some reference for those who are still headache about this matter.

How to maintain geranium in summer how to maintain geranium in summer (1) the choice of flowerpot, try to use small pot planting, basin not too deep, to ensure that the water can be normal dry and wet alternate.

(2) Try to shade, do not let the basin soil very hot, sooner or later a total of about two hours of direct sunlight, balcony family friends summer sun is the first, balcony direct light can not be placed in the bright light.

(3) Ventilation is very important. Even if you have an air conditioner, you'd better use a fan to set the temperature of the air conditioner a little higher to reduce energy consumption and ensure ventilation.

(4) In order to reduce the consumption of nutrition, we must reduce the consumption of nutrition to the greatest extent, especially for small and medium-sized seedlings. Cut off the old leaves and keep the young ones.

(5) The results showed that: when the fertilization was suspended, the phosphorus fertilizer was reduced, and the potassium fertilizer was applied normally; when the nitrogen fertilizer was stopped, it was not necessary to provide nutrients for the growth of new leaves in the high temperature environment; when the phosphorus fertilizer was reduced, it was necessary to inhibit the bud pregnancy of plants; when the potassium fertilizer was used normally, it was necessary to strengthen the plants, promote the roots and seedlings, and improve the resistance.

(6) Supplement energy, spray 2.5% glucose solution on the leaves (at night), and wash the leaves with water the next day. And ensure the ventilation to make the water evaporate quickly without ponding.

(7) As for watering, try not to spray water on the leaves frequently when the seedlings are in hot summer. Although the purpose of cooling can be achieved, if the water does not evaporate in time, the leaves will be rotten under high temperature, which will affect the health of the plants. Watering should not spray on the leaves as much as possible.

(8) For disinfection and sterilization, fungicides, carbendazim, chlorothalonil and thiophanate methyl can be used alternately after continuous high temperature or rain to prevent drug resistance, once a month or so; potassium permanganate can be diluted to lavender and irrigated directly to improve resistance.

Finally, I would like to say a few words: the precautions listed above are based on the Central Plains area (the highest temperature in the daytime lasts for more than 33), which is only for the reference of flower friends, and does not represent the position of all flower friends.
