Ornamental asparagus is an undemanding houseplant and therefore very popular with beginners. Best of all, it can be easily propagated. It works easily with rhizomes and seeds.

Ornamental asparagus can be propagated through seeds and rootstock division. Ornamental asparagus is an easy-care and undemanding houseplant that impresses with its filigree and feathery leaves. The flowers of the plant are relatively small and inconspicuous, but exude an intense fragrance. The ease of care makes the houseplant particularly popular with beginners. If you want to give away a copy or plant an asparagus yourself, you can easily multiply an existing plant.

You have two options:

  • through seeds
  • by dividing the rhizome

Both variants are successful, whereby the root division works a little faster. You need a little patience when sowing.

Split the rootstock of the asparagus

The ornamental asparagus forms numerous roots. If the pot gets too small, some of it will push up to the daylight. Then it is time to repot - ideally in spring. On this occasion you can split the root ball. Depending on how many new plants you want, once or several times. Put on work gloves before the action. Most types of asparagus have barely visible but sharp thorns that you feel painfully when repotting. Carefully remove the plant from the pot. The roots are delicate and break easily.

It is important to use a sharp knife or a saw so that you can make cuts that are as smooth as possible. The cutting tool must be absolutely clean. You can see where you have to cut by looking closely at the rhizome: try to cut off individual, independently rooted tuber parts. It is ideal if you produce as little cutting surface as possible.

The more even the cut surface, the better the divided rhizomes thrive. Remove dead root parts after the cut. You can no longer recognize functional, old roots by the brown color. Healthy ornamental asparagus roots are bright.

After dividing, remove as much of the old earth as possible. Then let the cut surface dry slightly. Additional dusting with charcoal dust has a disinfectant effect. Put the plant parts in normal, well-drained potting soil. Now just water and keep the plant moist. The ornamental asparagus needs a lot of water from spring to autumn.

Multiply ornamental asparagus by sowing

The plant has small red flowers. Then round fruits with seeds form. Sowing works well, the seeds germinate quickly at room temperature. However, the young plants grow very slowly and not all develop well.

The best time for sowing is from January to March. Until then, keep the seeds harvested in autumn cool and dark. Soak the seeds in warm water overnight before sowing, then no one better. Place the seeds in moist soil or cactus soil. Please do not use normal potting soil, the fertilizer it contains interferes with sowing. Cover the seeds very thinly with growing soil, moisten everything lightly and place the pot in a bright, warm place.

It is beneficial if you cover the vessel with a glass pane or stretch transparent film over it. The first shoots show up quickly, keep the substrate moist during the germination phase. After about four weeks you can separate the plants, after another eight weeks plant them in separate pots. Normal potting soil, rose soil or a mixture with compost is now well tolerated.
