Let's share some knowledge about when it's best to fertilize freshly potted orchids. Next, the editor will provide a detailed explanation for you.

When is it best to fertilize freshly potted orchids

It's best not to fertilize freshly potted orchids. If the orchids have already adapted to the pot, it's necessary to fertilize according to the orchids' growth and development stages, combined with weather conditions and the existing fertility of the planting material. Fertilization should be done moderately and lightly. Never rush to fertilize before the orchids have adapted to the pot. Not only will the orchids not be able to absorb and utilize the fertilizer, but it may also cause fertilizer burn, which is not worth the cost!

In fact, for freshly potted orchids that have not yet adapted and started growing, it's best not to fertilize.

Because the roots of freshly potted orchids have not yet formed beneficial microorganisms around them, they cannot absorb and utilize the fertilizer elements in the planting material or externally applied fertilizers. Applying fertilizer solution after repotting is not only detrimental to the growth of orchids but can also cause fertilizer damage.

Generally, there is no fixed time for when freshly potted orchids can be fertilized. It depends on their adaptation to the pot. Once fully adapted, fertilization can be applied.

If the orchids have started to adapt and grow, it should be based on the orchids' growth and development stages, as well as temperature, light, and seasonal changes.

It is necessary to consider the nature and effectiveness of the fertilizer, and the existing fertility of the planting material, to apply light fertilization, at the right time, and in the right amount. Mainly pay attention to the following three points:

1) Applying base fertilizer

Base fertilizer is applied to the bottom layer of the pot before potting, usually a slow-release fertilizer, intended to supply the orchids with nutrients throughout their entire growing period.

For example, decomposed sheep manure balls, bone meal, hooves, or feathers can be used as base fertilizer and placed directly in the bottom layer of the potting material when repotting orchids. When orchids are fertilized with base fertilizer, top dressing can be reduced or not applied.

Since the potting material needs to be changed every 1-2 years, even if chemical fertilizers are used for top dressing after adaptation, it will not affect the quality of the potting material.

2) Applying top dressing

Base fertilizer provides nutrients for the orchids throughout the year, with slow efficacy. When growing orchids with granular potting material, adding a small amount of base fertilizer is effective, and if the potting material is fertile, base fertilizer may not be needed.

However, during special periods of orchid reproductive growth, additional nutrients are needed, at which time top dressing should be used to supplement. Top dressing usually consists of a dilute liquid fertilizer, such as "Flower More 2" water-soluble fertilizer, applied once every 7-10 days, with 1-2 applications per month being appropriate.

3) Foliar feeding

Foliar feeding, also known as leaf feeding, involves spraying a diluted chemical fertilizer solution on the front and back of orchid leaves to supplement the insufficiency of root fertilization.

Foliar fertilizers take effect quickly and require a small amount, which can enhance the disease resistance of orchids. However, foliar feeding cannot replace root fertilization.

Only water-soluble fertilizers such as urea, monopotassium phosphate, and calcium superphosphate should be used, and they should be applied in the early morning or evening when the weather is cool and sunny. The concentration should be between 0.1% and 0.2%, as too dilute will have low efficacy, and too concentrated will be difficult to absorb and can easily damage the seedlings.

In summary, it's best not to fertilize freshly potted orchids. If the orchids have already adapted to the pot, fertilization should be based on the orchids' growth and development stages, combined with weather conditions and the existing fertility of the planting material, and applied moderately and lightly.

Never rush to fertilize before the orchids have adapted to the pot. Otherwise, it will not only prevent the orchids from absorbing and utilizing the fertilizer but can also cause fertilizer burn, which is not worth the cost!
