How to Fertilize a Cactus Grafted Orchid After It Survives

Apply fertilizer to the grafted plant by burying base fertilizer. For example, thoroughly decomposed sheep manure or poultry manure can be used as a base fertilizer placed at the bottom of the pot; wood ash is commonly used as a potassium fertilizer, which can be mixed into the soil; and there is also dried cow dung from the countryside, which, after fermentation and decomposition, can be buried at the edge of the flower pot. It can not only serve as fertilizer but also has the effect of loosening and ventilating, making the potting soil looser.

Actually, fertilizing the orchid grafted on the cactus is the same as fertilizing the cactus. As long as the cactus is well cultivated and strong, the orchid will obtain abundant nutrients from it, and the orchid will also grow well.

How to Fertilize an Orchid Grafted on a Cactus

Fertilizing an orchid grafted on a cactus should be done through the following two methods:

First, by burying base fertilizer to apply fertilizer to the grafted plant

For example, thoroughly decomposed sheep manure or poultry manure can be used as base fertilizer placed at the bottom of the pot; wood ash is commonly used as a potassium fertilizer, which can be mixed into the soil.

Also, dried cow dung from the countryside, after fermentation and decomposition, can be buried at the edge of the flower pot. It can serve as fertilizer and also has the effect of loosening and ventilating, making the potting soil looser.

Second, by spraying foliar fertilizer to provide nutrients to the grafted plant

Such as Huaduo No. 2, potassium dihydrogen phosphate, etc., dilute the concentrate according to the dilution ratio marked in the instructions to make a diluted solution, and spray it on the stems and leaves of the orchid to provide the plant with sufficient flowering fertilizer and promote its bud differentiation.

This is generally done when the orchid enters the bud differentiation period in autumn. Spraying once every 15 days is recommended.

Precautions for Fertilizing an Orchid Grafted on a Cactus

1) Fertilizer Selection

The general requirements for fertilizers for orchids grafted on cacti are: they must be thoroughly decomposed; they should not contain salt; and they should be mainly phosphorus and potassium fertilizers with nitrogen fertilizers as a supplement.

2) Reasonable Fertilization

So-called reasonable fertilization means that fertilization should be timely and appropriate, with the types and concentrations of fertilizers applied properly. Fertilize when the plant needs it the most, which is mostly during the peak growing seasons of spring and autumn, so fertilization is often done in these seasons.

Generally, apply top-dressing fertilizer once every 10 to 15 days, 2 to 3 times in spring, and 1 to 2 times in autumn. During the high-temperature period of summer, fertilization should generally be stopped.

3) Low or High Temperatures

Do not fertilize cacti during their dormant period; do not fertilize immediately after a transplanted seedling has developed new roots; and do not apply too much fertilizer to cacti with aged roots or young seedlings to avoid burning the roots.

Water with a bad smell, fish washing water, or meat broth with salt should not be used as fertilizer. Avoid applying concentrated or raw fertilizers.
