What should I pay attention to in May?

May (solar term: long summer, small full) is a sunny day with suitable temperature and clear weather in the northern region. Many flowers have fully entered the growth period, which is also an important period for flowers at different growth stages to strengthen fertilizer and water management.

Maintenance and management: ① For the flowers that bloom for a long time or for many times in a year, the flower branches should be cut short or pedicels should be cut off after flowering, and phosphorus-based fertilizers combined with nitrogen and phosphorus should be applied in time to make them continue to sprout and bloom; For flowers that bloom only once a year, after the flowers wither, cut off or erase the residual flowers or cut off the pedicels, and apply nitrogen and phosphorus fertilizer once to supplement the nutrients consumed during flowering, which is convenient for regeneration. ② For other fruit trees with pregnant buds that have not blossomed, or have young fruits, or flowers that are in the growing period, topdressing should be performed 1 ~ 2 times. For the fruit trees with pregnant buds and fruits, it is still necessary to apply fertilizer combined with phosphorus and potassium, properly thin the fruits, or remove the newly grown branches and leaves after the fruits, so as to "protect the fruits". (3) Evergreen and other tropical plants should all leave the house, change pots, prune and fertilize. (4) In the growth or flowering period of all kinds of flowers, it is necessary to prevent the pot soil from being too dry and affecting the appreciation, and maintain a certain humidity.
