If you want to fertilize Phalaenopsis correctly, you need to choose different fertilizers and different application methods according to the season. Spring and summer is the growth period of Phalaenopsis, at this time, dilute liquid fertilizer can be applied every 7- 10 days. Fertilizer can be organic fertilizer, and nitrogen fertilizer and potassium fertilizer should be applied after flowering.

Autumn and winter are the growing periods of Phalaenopsis stems. At this time, phosphate fertilizer should be applied instead, which can promote the differentiation of flower buds and facilitate their flower formation. Generally, it can be applied once every 2-3 weeks, which can meet its growth needs. However, if the temperature continues to be low in winter, fertilization will be suspended for a period of time.

When fertilizing Phalaenopsis, we should pay attention to the principle of applying thin fertilizer frequently, and not applying raw fertilizer, otherwise it will easily lead to fertilizer damage to plants. Generally, the fertilization time is after watering in the afternoon. After fertilization, the plants need to be washed with a lot of water to avoid inorganic salt residues and endanger the health of the plants.

After Phalaenopsis blooms, it needs an operation to cut off the flower stem. It should be noted that not all flower stems are simply cut off, but the branches at the root of the flower stem are kept for about 3-5 knots, and then the upper part is cut off, so that the plant can continue to bloom after a period of dormancy and maintenance.

When all the flowers are in full bloom, we should cut off all the residual flowers in time. Failed flowers have no ornamental value, but they will still adhere to the branches of plants and continue to consume nutrients, so they should be cut off with scissors in time to save nutrients for plant growth and development.

After pruning, prepare carbendazim solution or potassium permanganate solution diluted about 500- 1000 times, rinse the wound of the plant with the solution, apply plant ash to dry the water, and store the plant in a cool and ventilated place for a period of time. When watering, be careful not to splash water on the wound, otherwise it will easily cause decay.

If pruning is not timely enough in the maintenance process to make plants grow fruits, then the fruits should be pruned in time. Orchidaceae plants generally don't need fruits, and the fruits are difficult to grow and mature, and the seed reproduction is extremely difficult, and the survival rate is extremely low, which consumes a lot of nutrients and is not suitable for sowing and reproduction.
