What is the best foliar fertilizer for orchids? (Precautions for spraying foliar fertilizer for orchids)

The orchid has flowing leaves and graceful posture, appearing very noble and dignified. Just looking at the plant and leaves is already very moving. If it is lucky enough to bloom, it will be even more beautiful.

If you want to grow orchids well, spraying foliar fertilizer is very important. It can be said that it is very important for maintaining the beauty of the leaves and the health of the plants.

Proper spraying of foliar fertilizer during the flower bud differentiation period is also of great significance for the germination of flower buds and future flowering.

So, when should we spray foliar fertilizer on orchids? What should we pay attention to when spraying foliar fertilizer?

1. Urea:

In daily fertilization, I mostly use solid organic fertilizers. Every month, by applying a small amount of fertilizer to the planting material, I can supplement the daily needs of orchids.

But during the growth period of orchids, I will use urea to promote growth.

I usually use urea as a foliar spray. The main reason why I don't use it on the planting material is that I'm afraid that excess "nitrogen" will remain in the flower soil and affect flowering.

However, if you use foliar spray, the excess nitrogen can be washed away through the foliar spray after the orchid has absorbed some nutrients.

When using urea as foliar fertilizer, you can use it in the following way:

Find a 1.25 liter mineral water bottle or cola bottle. Use the bottle cap as a meter, add about half a bottle cap of water to 1.25, stir evenly, and then you can use it as foliar fertilizer spray. Generally use it once a month in spring and autumn.

2. Potassium dihydrogen phosphate:

It is not uncommon to use potassium dihydrogen phosphate for orchids. I believe that most orchid lovers are using it. This is an efficient and safe foliar fertilizer. Proper use will make orchid seedlings more vigorous and bloom more. Here I know there are three main functions:

1. End of dormancy period :

When the temperature in winter and summer is too low or too high for orchids to tolerate, they will enter a dormant or semi-dormant period.

Then when we resume normal growth, we can use "potassium dihydrogen phosphate" to wake up the dormant orchids. Mainly, "potassium dihydrogen phosphate" can promote cell activity.

2. Growth period:

When orchids are in the peak growth period, leaf buds are also growing. At this time, use "potassium dihydrogen phosphate" to promote the growth of the root system. If the root system is vigorous, the new buds will be full.

The main thing is that "potassium dihydrogen phosphate" also has the effect of promoting rooting, and can promote photosynthesis and improve the efficiency of nutrient absorption.

3. Promote flowering:

About 3 months before the orchid blooms, as long as the temperature is within the range suitable for orchid growth, approximately between 15 and 32 degrees Celsius, healthy orchids can be forced to bloom. Potassium dihydrogen phosphate can promote flowering and prolong the flowering period.

The method used is generally to use a straw to suck the 1 gram mark, and then directly add a 1.25 liter Coke bottle of water. Depending on each stage:

1. Wake up from hibernation. About a full bottle of water.

2. During the growth period, about 4/5 to a full bottle.

3. To promote flowering, use about 4/5 of the bottle.
