What is the best fertilizer for asparagus plants?
Before the spears appear, apply 1.2 pounds of 10-10-10 fertilizer per 100 square feet and cultivate lightly into the soil. In July of the second growing season, sidedress with another 1.2 pounds of 10-10-10 fertilizer per 20 linear feet of row.
What is the best fertilizer for ferns?
Fertilization. Ferns are relatively light feeders compared to many other foliage plants. They prefer a balanced fertilizer, such as 20-10-20 or 20-20-20, with micronutrients applied at approximately 200 ppm nitrogen. Too much nitrogen can cause tip burn on the roots and leaves if the plant becomes dry.
How do you keep an asparagus fern happy?
Caring for asparagus ferns
Reduce watering in autumn, and water more sparingly in winter. Feed once a month with a liquid feed in spring and summer. Provide some humidity by grouping plants together or misting regularly, especially in summer or if the central heating is on. Repot every couple of years, in spring.
How do you make asparagus fern bushy?
Take a sharp pair of clean scissors and make a snip where you would like the stem to end.

* Coffee grounds alone would be too acidic, but if you’re mixing them in with other kitchen waste and especially yard waste like leaves, they’re fine. Asparagus prefers a soil pH between 6.5 and 7, which is mildly acidic. Coffee grounds can run 5 or less on the pH scale by themselves.
How often should you fertilize asparagus?
Generally, it is not necessary to apply fertilizer for an established asparagus crop until after harvest. In fact, delaying fertilization until after harvest can reduce early weed growth. For sandy coarse-textured soils, however, 20-25 lbs N/acre in the spring may be beneficial for spear development.
Do potted ferns need fertilizer?
Ferns do not need a lot of fertilizer, especially if you have nourished the soil with compost. Garden ferns should be fertilized annually in the spring. Outdoor container ferns can be fertilized in the spring and once again midsummer if the plant looks unhealthy.
How often should you fertilize ferns?

Asparagus growing in sandy soil should be watered more than once per week in the absence of rain, and heavy clay soils may not need to be watered as often.
How do asparagus ferns encourage new growth?
To promote dense plant growth, pinch back your asparagus fern’s stem tips by about a third every few months. If the plant’s shape becomes too sprawling, cut back the oldest stems close to the soil to encourage new growth.
How often should you repot an asparagus fern?
every three years
Repot every three years with a ‘Houseplant’ labelled compost during the spring. Water the soil 24hrs before the transplant to reduce the chance of damaging small hairs found on the roots. Pests aren’t usually an issue due to the lack of thick surfaces for an infestation to develop.
Should you trim an asparagus fern?
