If you want to know the best foliar fertilizer for orchids, here are some small green plant maintenance tips to share with everyone.
What is the best foliar fertilizer to spray on orchids
When applying foliar fertilizer to orchids, attention should be paid to timing and dosage. Mastering the right time can achieve twice the result with half the effort. During fertilization, the spray can be applied to both sides of the leaves to increase the absorption area and achieve better results. After foliar fertilization, a clear water spray can be used 8 to 12 hours later.
Orchid leaves are graceful and elegant, giving a noble and dignified appearance. Just looking at the plant and leaves is very attractive, and if they bloom, they are even more beautiful.
In order to raise orchids well, spraying foliar fertilizer is very important, as it is crucial for maintaining the aesthetic appeal of the leaves and the robustness of the plant.
Applying foliar fertilizer appropriately during the bud differentiation stage is significant for the germination of flower buds and future blooming.
So, when should orchids be sprayed with foliar fertilizer? What should be paid attention to when spraying foliar fertilizer?
1. Urea:In daily fertilization, I mostly use solid organic fertilizer, applying it in small amounts through the "frequent application of thin fertilizer" method every month to meet the daily needs of orchids.
However, during the growing period of orchids, I use urea to promote growth.
I usually apply urea through foliar spraying. The main reason I don't apply it to the growing medium is the fear that excess nitrogen will remain in the soil, affecting blooming.
But if using foliar spraying, after the orchids absorb some nutrients, the excess nitrogen can be washed away through the foliar spray.
Using urea as foliar fertilizer, you can follow this method:
Find a 1.25-liter mineral water bottle or cola bottle. Use the cap as a measuring device, add about half a capful of urea to 1.25 liters of water, mix well, and then use it as foliar fertilizer for spraying. Generally, use once a month during spring and autumn.
2. Potassium Dihydrogen Phosphate:Potassium dihydrogen phosphate is not uncommon for orchids, and I believe most orchid enthusiasts are using it. This is an efficient and safe foliar fertilizer that, when used properly, can make orchid seedlings more vigorous and bloom more. I know of three main functions:
1. End of Dormancy:
In winter and summer, when orchids can withstand low or high temperatures, they may enter a dormant or semi-dormant state.
When they enter the normal growth phase, we can use "potassium dihydrogen phosphate" to wake up the dormant orchids. This is mainly because "potassium dihydrogen phosphate" can promote cell activity.
2. Growth Period:
During the vigorous growth period of orchids, which is the vigorous growth period of leaf buds. Using "potassium dihydrogen phosphate" at this time can promote root growth, and only when the roots are vigorous will new buds be plump.
Mainly because "potassium dihydrogen phosphate" also has the effect of promoting root growth and can promote photosynthesis, improving nutrient absorption efficiency.
3. Promoting flowering:
About 3 months before the orchid flowering period. As long as the temperature is within the suitable range for orchid growth, about 15 to 32 degrees Celsius, you can promote flowering in healthy orchids. Potassium dihydrogen phosphate can promote flowering and extend the flowering period.
The method of use is generally to use a straw to吸取 to the 1-gram mark, then directly add it to 1.25 liters of water in a cola bottle. Depending on the different stages:
1. Waking up from dormancy. About one full bottle of water.
2. During the growth period, about 4/5 to full bottle.
3. Promoting flowering, about 4/5 of the bottle.
