How to prune the branches and leaves of asparagus fern, and how tall can it grow?

Speaking of asparagus fern, it is a very beautiful and unique foliage plant. Its leaves are particularly small, its stems are soft, and its orderly high-and-low shape makes it look very distinctive. It is a common potted plant for home decoration. However, when growing asparagus fern, attention should also be paid to pruning, so exactly how should asparagus fern be pruned? Let's learn about it together below!

How to prune the branches and leaves of asparagus fern

1. Pruning when cladodes are missing. When the growth position of small cladodes on the main branch is not ideal or they are missing for some reason, short pruning can be carried out at an appropriate position on the main branch to force the dormant buds there to sprout. Generally, the pruning height is the height at which the cladodes sprout, and the position of the thorns on the branch is the position where the cladodes sprout. The greater the thickness of the branch, the higher the sprouting rate of the dormant buds.

2. Renewal pruning of the whole plant. If the branches and leaves of the whole plant grow poorly because of strong sunlight scorching, dry potting soil, lack of fertilizer, or some unknown reason, the whole plant can be renewed. During renewal pruning, all cladodes can be cut off, but attention should be paid to the positions of the recurved thorns on the branches, because they determine whether the distribution of the retained branches is even. Pruning in the growing season generally makes it easy to sprout new branches. After pruning, the amount of watering should also be appropriately reduced, and the potting soil must absolutely not be kept too wet, otherwise the pruning will fail.

3. Pruning of trailing branches. Trailing branches are generally weak and slender. If you do not want to keep them for propagation and want the plant shape to look good, they can be cut off from the base all at once. If you want to increase the number of cladodes or fill a certain gap, they can be shortened at a certain position. During pruning, special attention should be paid to comprehensive management such as small amounts of fertilizer.

How tall can asparagus fern grow

Asparagus fern has a graceful posture, slender and soft branches, an orderly high-and-low form, and is elegant and distinctive. However, if it is not pruned, asparagus fern will grow taller and taller. Asparagus fern is a climbing plant, and its roots are semi-fleshy. Moreover, asparagus fern grows very quickly. After several years of cultivation, the branches will grow taller and taller, generally reaching 2 to 3 m, or even longer.

How to keep asparagus fern from growing tall

If you do not like asparagus fern growing tall, then the following content is what you need. Do the following points, and you can keep the growth of asparagus fern under your control.

1. Choose dwarf varieties

Horticulture is really advanced now. If you want it not to grow tall, it will not grow tall. When purchasing asparagus fern, directly choose dwarf varieties. During care, as long as you ensure the plant shape remains upright and not messy, its height will always remain as it was at the beginning.

2. Reduce nutrients

To keep asparagus fern from growing tall, you need to limit its growth, and reducing nutrients will do. First is the choice of soil. Choose semi-sandy soil, which has fewer nutrients. Next is fertilizing. For newly grown plants, generally apply nitrogen fertilizer water once a month. For plants that have grown for 2 to 3 years, the growth trend is basically set, and nutrients fluctuating between more and less will cause leggy growth, so applying fertilizer once every two months is enough.

3. Prune frequently

Asparagus fern grows very fast, basically about the same speed as human hair growing. Cut off dead branches and long stems at any time to keep the plant short and sturdy. At the same time, promptly cut off trailing branches to keep it upright, graceful, well-spaced, and green.

4. Spray chlormequat

The very last method is to spray a dwarfing chemical, used at a ratio of 3 parts per thousand. This method is more suitable for lazy people, but its biggest drawback is that asparagus fern sprayed with chlormequat will not develop the lush feeling of a welcome pine, and the spacing between branches will be larger, looking sparse.

What to do if asparagus fern grows wildly

The wild growth of asparagus fern can be suppressed by pruning, but the cut asparagus fern will continue to grow, wasting the nutrients of the asparagus fern for nothing. The best way is to fix and shape the asparagus fern.

For asparagus fern that has “grown wildly”, it is best to guide it according to the situation. Use bamboo strips or wire to weave a frame in your favorite shape, such as spherical, fan-shaped, or a well-shaped frame and fix it on the flowerpot, providing support for the long branches of the asparagus fern to climb. As the asparagus fern extends, it can be guided according to the situation so that it is evenly distributed on the surface of the frame. Where fixation is needed, it can be tied with thin string.

In this way, the wild growth of asparagus fern is suppressed. Not only can you enjoy the uniquely shaped asparagus fern, but it will also not waste the nutrients of the asparagus fern for nothing.

As mentioned above, although everyone says that messiness is also a kind of beauty, a natural beauty, if it is slightly pruned, it will look even more perfect and beautiful visually! If asparagus fern is grown well, it can grow very tall, but if it is too tall, it will not look as good, so it should also be pruned occasionally in ordinary times.
