In the current flower market, orchids are always at the top of the list for aesthetic value and are favored by many people. Orchids are derived from the natural environment, so the synthesis of nutrients is natural, but the source of nutrients is not enough to bring about comprehensive development.
Therefore, orchid farmers have applied additional methods of fertilizing to give orchids the most abundant source of nutrients. However, caring for orchids is not an easy thing, especially when the fertilizer market is as active as it is today. To have more useful experiences for yourself, we invite you to follow the information about fertilizer for orchids in the article below.
What fertilizers are used for orchids?
Orchids can absorb nutrients from both organic and inorganic fertilizers. Specifically:
+ Manure, traditional fertilizers: chicken manure, goat manure, cow dung …
+ Processed agricultural organic fertilizers such as: microbial organic fertilizers, bio-organic fertilizers…
+ Single fertilizers: Potassium, nitrogen, phosphorus.
+ Mixed fertilizers: NPK, DAP…
+ Fertilizer through the sprinkler irrigation system
- Foliar fertilizers
- Fertilizer through the roots.
- Slow dissolving.
- Fast dissolving manure.
According to the experience of orchid growers, orchid roots will be best developed after planting when supplemented with nutrients from: SuperThrive, Vitamin B1, N3M …
Some fertilizers to help stimulate sprouting for orchids are recommended:
- Super budding and budding of Buffalo Head fertilizer.
- Super burst Growmore.
- Products sprouting and sprouting Hung Nguyen.
- Stimulates the blooming of Keiki Super Green.
- Extracted from seaweed.
- Humic Acid.
These fertilizers when used need to be based on a standard dosage. If the amount of fertilizer is too much, the dormant sprouts will shrivel, causing the plant to have great effects. It even causes orchids to stop growing roots.
In addition, orchids can also receive essential nutrients from slow-release fertilizers such as: Sfarm vermicompost, Japanese fertilizer, Rynan slow-dissolving fertilizer, etc. Farmers can also combine using them. add micro, macro and intermediate fertilizers to supplement the best amount of nutrients for orchids.
The process of using fertilizer for orchids
From the beginning of planting to the time the plant flowers about 3 months, new sprouts of the plant will begin to grow. This is a very suitable time for farmers to use foliar fertilizers containing a lot of NPK nitrogen at the ratio of 30-10-10 to help plants grow quickly with the best quality.
In the next 4 months of orchid growth, the amount of NPK fertilizer used by farmers should be at a rate of 20-20-20 to balance the nutrient source for the plant.
Continue in the next 3 months, farmers need to use fertilizers containing high potassium and phosphorus, such as NPK ratio 6-30-30 to help plants have resistance to pests and diseases and weather conditions. unstable weather. At the same time, providing this amount of nutrients to the flower is also a turning point for the plant to switch to the stage of sprout differentiation and flower bud formation.
In addition, during the growing process of orchids, farmers can periodically use additional intermediate elements such as: Ca, Mg, S or trace elements such as: Co, Bo, Mn, Fe, Si, Zn …
If farmers only prioritize using NPK fertilizers, orchids will not be able to receive essential nutrients. Since then, orchids grow slowly, leaves few, flowers are small in size and easily infected.
Things to note when fertilizing orchids
Farmers pay attention to the most suitable time to fertilize orchids is from 7 to 9 am or from 4 to 5 pm when the weather is cooler. Farmers can adjust the time to spray fertilizer for orchids depending on weather conditions.
Before spraying fertilizer, you also need to pay attention to watering the orchid with a little water to improve nutrient absorption. After about a few hours of spraying fertilizer for orchids, growers need to pay attention to using clean water to re-water the plants to avoid the situation of fertilizer clinging to the leaves causing fire.
Note: Choose a misting solution for orchids
The fertilizer coverage must be uniform on the underside of the leaves so that the plant can quickly absorb the required amount of nutrients. Although it is a foliar fertilizer, farmers can spray wet the whole roots or spray directly into the orchid growing medium.
Note, if the newly planted orchid is still small in size, the amount of fertilizer used needs to be less than in the recommended packaging. The dose of fertilizer can be increased gradually according to the growth stage of the plant.
In the case of using a combination of manure to fertilize plants, it should be noted that the manure must be composted before for the nutrient content to meet the standards. At the same time, composted manure will eliminate fungi, insects and sources of pests. In the color of rain, limit the use of manure for orchids because of the relatively high possibility of causing root rot.
It can be said that adding nutrients to orchids is not simple, flower caretakers need to ensure that they provide the right fertilizer at the right time. Hopefully with the article we share, providing nutrients for orchids will no longer be a big concern for orchid enthusiasts.
