What Soil Is Best for Growing Asparagus Fern? Detailed Fertilizing Guide
When it comes to planting flowers, plants and trees, the issue most people care about is daily care, and watering is a big problem for many plants. For asparagus fern (Asparagus setaceus), besides watering, choosing the potting soil for growing it is also very important. Asparagus fern grows best in loose, fertile, well-drained sandy soil, and clay must absolutely not be used.
What Soil Is Best for Growing Asparagus Fern
1. It has fairly high requirements for soil and needs soil with a very high humus content. It is best not to use clay; sandy soil is the best. It can only grow well in soil that drains well and is very loose and fertile.
2. Repot it with fresh soil every two years, and the mix must be carefully prepared. You can use rotted leaves plus peat or fine sand, and you can also add some chicken or duck manure to the pot.
3. You must give it a pot with very good breathability. If the soil is too dry or there is too much water, its roots will rot, and then the leaves will turn yellow and drop. Wait until its soil is almost dry before watering again, and do not water too frequently. From June to September, give it a liquid fertilizer once every half month; either chemical fertilizer or organic fertilizer is fine, and you can also buy a special fertilizer on the market.
How to Fertilize Asparagus Fern
I. Fertilizing Methods
1. Spring: In spring, fertilize once a week, and the fertilizer concentration should be on the weak side.
2. Autumn: As in spring, fertilize once a week, and the fertilizer concentration should be on the weak side.
3. Winter: In winter, fertilize once every 15 to 20 days, and the fertilizer concentration should be on the weak side.
4. Growing season: During the growing season of asparagus fern, apply a top dressing 1 to 2 times a month, mainly phosphorus fertilizer and nitrogen fertilizer, or other liquid fertilizers are also fine; this can promote the growth of asparagus fern.
5. Flowering period: During the flowering period of asparagus fern, the amount of fertilizer can be appropriately reduced.
6. After shaping: After asparagus fern has taken its shape, fertilizing can be reduced.
II. Precautions
1. When fertilizing, never apply concentrated fertilizer, and do not apply too much fertilizer; you can reduce the amount and increase the frequency.
2. During the flowering period, the amount of fertilizer must be controlled, otherwise it is very easy to make asparagus fern grow rampantly and cause its flowers to drop prematurely.
3. When fertilizing, be careful not to splash it onto the leaves of asparagus fern. After fertilizing, you can spray water on its leaves with a spray bottle to reduce the damage fertilizer does to the leaves.
How to Make Asparagus Fern Grow into a Full Pot
1. Pruning
I believe everyone knows that pruning is a way to make it grow better. Usually we should pay attention to its growth state, cut off its old branches, and promptly pinch back its tips; this way it can grow upright and full.
2. Soil
If you want it to grow into a full pot, soil is also one of the key points. It needs relatively soft and slightly acidic soil, which is better for its growth and makes it easier to grow into a full pot. Soils with this characteristic include leaf mold, pine needles and peat.
3. Watering
I need to pay attention to daily watering, because with water it will grow relatively fast, but you cannot pour too much water at once, so we can spray water on the leaves, and in winter we can spray a little less.
4. Light
It relatively likes diffused light, and the light must not be too strong, so we should put it in a relatively shaded place, or let it receive diffused light. Of course, letting it get some ventilation is even more useful for growing into a full pot.
Propagation Methods of Asparagus Fern
1. Seed propagation: Seed-bearing mother plants are usually grown in the ground in a greenhouse, and asparagus fern seeds mature successively from December to April of the following year. Because asparagus fern seeds have a short lifespan, they should be sown promptly after collection or stored in sand. When sowing, remove the seed coat, take out the seeds and sow them in a shallow pot or sow them individually in a flowerpot with an inner diameter of 7cm. If sown in a shallow pot, sow the seeds individually at a spacing of 2cm between plants and rows, press the seeds into the soil, cover with 2-3mm of soil, cover the shallow pot with glass, and provide shade. Keep the temperature at about 20°C, and they will germinate in about 20-30 days.
2. Division propagation: For plants 4-5 years old, division can be done in early spring. Operate carefully and injure the roots as little as possible. After the plants recover from transplanting, strengthen fertilizer and water management to encourage new shoots to sprout. This method has a low propagation rate, and after division the new plants are not neat in shape, so it is used less often.
Asparagus fern is a plant with very high ornamental value. Although its care is rather troublesome and it has certain requirements for soil, water, fertilizer and so on, that does not mean it is very difficult to grow. So friends who like it can still grow asparagus fern well as long as they put in a little more patience.
