What to do for orchid care in summer

1. Pay attention to shading: as summer arrives, sunlight gradually becomes stronger, so check whether the shading is correct and adjust and improve it.

2. Ventilation and cooling: summer temperatures are high, so pay special attention to ventilation to avoid high temperatures and stuffy heat that harm the orchid plants.

3. Strengthen sterilization: at the transition between spring and summer, temperature and humidity increase, making diseases likely to occur, so observe the orchid plants frequently, watch for symptoms, and strengthen prevention and control.

4. Protect against rain and typhoons: in summer, heavy thunderstorms or plum rain and continuous overcast rain occur, and some orchids cannot withstand long periods of rain or excessively high humidity, so they need shelter from rain or reduced humidity. During typhoon season, pay attention to typhoon protection; after violent storms, infection is most likely, so sterilization and disease prevention work must be done.

5. Change the fertilizer: orchids absorb fertilizer most easily at 25°C; if it exceeds 33°C, reduce the frequency of fertilizing and lower the concentration to prevent fertilizer damage. In addition, after summer, new shoots have gradually matured, so increasing the proportion of phosphorus and potassium fertilizer helps promote sturdy stems and flowering.

6. Increase humidity: in summer, orchid leaves evaporate water quickly, especially when cultivated on rooftops, balconies, or indoors, so attention should be paid to air humidity and replenishing water in the pots.

7. Prevent fruit drop: orchid capsules from spring hybridization need protection from high temperatures or accidental damage during their summer development period to prevent fruit drop.

8. Cut off spent flowers: during the transition between spring and summer, many orchids are nearing the end of their flowering period, so spent flowers must be cut off early to reduce nutrient consumption.
