How to Fertilize Asparagus Fern? Master the Latest Fertilizing Techniques
As a perennial evergreen herbaceous plant, the asparagus fern has a relatively high demand for fertilizer, and only with sufficient nutrients can it grow more vigorously. However, many people do not know how to fertilize asparagus fern, nor what fertilizer to use. Let's take a look at the fertilizing techniques for asparagus fern below.
1. Fertilizing Time
Although the asparagus fern has a relatively large demand for fertilizer, it does not need to be fertilized every day, and the amount of fertilizer varies across growing seasons, so pay close attention during fertilizing. Generally, after spring arrives, the asparagus fern enters its growing period, when it needs a large amount of nutrients to promote growth, so it can be fertilized once every half month. After summer arrives, fertilizing should be reduced accordingly, because the summer climate is relatively hot and the asparagus fern grows relatively slowly, so fertilize as little as possible. After autumn arrives, the temperature is cool and the asparagus fern enters its growing season again, so the amount of fertilizer should be increased, but not too much, otherwise root burn will occur. In winter, basically do not fertilize.
2. Fertilizing Methods
As a foliage plant, the asparagus fern is best fertilized mainly with nitrogen fertilizer. Generally, dilute nitrogen fertilizer 10-20 times and apply it as a liquid. But except for hydroponic asparagus fern, you can also apply granular chemical fertilizer based mainly on nitrogen, phosphorus and potassium, generally by hole application, or dilute it and water it on, which is good for root absorption, promotes plant growth, and will not cause root rot. Slow-release fertilizers on the market contain a certain amount of nitrogen, phosphorus and potassium, and the nutrients are wrapped in a membrane and released slowly; each application can be effective for as long as four to twelve months. This kind of fertilizer is relatively mild, clean and hygienic, and its release is also related to temperature, so it is very suitable for asparagus fern; basically, after one application you do not need to worry about it.
3. Precautions
Many friends, during fertilizing, often apply fertilizer too concentrated at one time. Especially after the asparagus fern has grown and taken shape, the amount and frequency of fertilizing can be properly controlled. But during the vigorous growth period, still apply 1-2 topdressings of nitrogen and phosphorus fertilizer each month; other liquid fertilizers are also fine, to promote plant growth. During the flowering period of the asparagus fern, do not fertilize too much, to avoid excessive vegetative growth and cause the flowers to fade prematurely.
