Raise orchids in summer and use vegetarian methods to bloom.

It has always been said that bluegrass is suitable for accomplishment and is afraid of being fat and avoiding fat. In fact, orchids are afraid of thick fertilizer, and proper fertilization is very necessary for orchids to thrive. For summer, if you want to raise orchids well, you need to learn the method of "accomplishment". In this way, your orchids can blossom.

So, what is the orchid "literacy" law? Flower friends look down carefully:

Early summer (April-June) is the new bud growth period of orchids. Nitrogen and potassium should be the main fertilization. Orchids can use organic liquid fertilizer for orchids, once every 10 to 15 days. From mid to late June, orchids have entered the stage of accumulating nutrients and strengthening false bulbs (for bud growth). Fertilizers based on phosphorus and potassium fertilizer should be applied, and flower friends can use organic nutrient solution for orchids to dilute their roots by 500-800 times.

In the early summer, special liquid fertilizer for orchids should be applied every 10 to 15 days. When pouring liquid fertilizer, try not to pour it into the leaf center as much as possible from the edge of the basin, and pay attention to apply it slowly from the edge of the basin to avoid pouring into the leaf center. When the heat temperature is higher than 30 ℃, all kinds of orchids should reduce fertilizer application, and orchid organic liquid fertilizer can be used to dilute 1000 and spray foliar topdressing once every 20 days.

Foliar fertilization should be carried out in the evening to prevent high temperature fertilization from injuring leaves. When the orchid seedlings are strong, they can lay a good foundation for the germination and growth of flower buds. There will be more blossoms.

In addition, the "literacy" method is used to apply organic fertilizer to orchids in summer. Organic fertilizer must be fully fermented and ripened (after 1-2 years of fermentation), and then diluted with clean water. Fertilization should be carried out after sunset in the evening, and the next morning, water should be watered through the pot orchid, or sprayed once more (commonly known as "backwater"), so as not to cause disease at the root tip or leaf center.

If flower friends find that the leaf tips of orchids are scorched and black in summer, it is usually due to excessive fertilization. At this time, fertilization should be suspended for 30 to 40 days. If the orchid leaves appear yellowed and thin, it is likely to be caused by lack of fertilizer, so topdressing should be carried out. Fertilization must follow the principle of "suitable application of thin fertilizer", especially for young seedlings and weak seedlings.

Once it is found that the orchid is fertilized too heavily, the soil must be changed immediately, and the roots of the orchid must be washed and then recultivated with plain soil. In addition, during the flowering period of Jianlan in summer, flower friends should suspend fertilization during the scape unearthed or flowering, so as not to cause rotten buds caused by fertilizer and water pouring into the buds.
