How to grow orchids so they bloom every year on a home balcony

The hardest part of growing orchids on a balcony is keeping them alive; as long as they survive, blooming is not difficult.

1. A so-called balcony certainly has no shortage of light; the main thing is to provide shade in summer. Starting every May 1, put up a shade net.

2. Around the orchids, grow several larger potted tree bonsai, arranged at varying heights. Normally you can mist the trees often to keep them moist, and this way the environmental humidity improves.

3. If ventilation is not very good, use an electric fan directed at the trees; orchids like to enjoy indirect, shifting breezes.

4. On a balcony without a roof, it is best if dew can reach the plants at night; if not, keep them as close to the window as possible so they receive more outdoor air at night.

5. Apply phosphorus and potassium fertilizer irregularly; phosphorus fertilizer promotes flower buds, and potassium fertilizer supports the flower stems. These two fertilizers are indispensable. You can spray potassium dihydrogen phosphate lightly several times.

6. Once there are flower buds, the temperature should not be too high. If windows can be opened, open them as much as possible (above zero degrees), letting the orchids fully vernalize so they can produce good flowers.

Do these six things well, and I believe your orchids will also bloom every year.
