Repotting

Repot Smilax Asparagus Fern at the beginning of the growing season only when it becomes root-bound; when the roots begin to grow through the drainage holes.

Use a pot which is only 1 size larger than the current one. Ensure that the pot has a drainage hole to avoid soggy soil as it can result in root-rot disease and death of the fern. Check out these Flower Pots with Multi Mesh Drainage Holes on Amazon.

You can divide the large ferns during repotting to propagate new plants.

Pruning

Pruning Smilax Asparagus Fern requires cutting back of the old stems to make room for new growth. Trim the dead leaves and branches to keep the fern neat and tidy.

Propagation

Smilax Asparagus Fern (Asparagus asparagoides) can be propagated at the beginning of the growing season from seeds, cuttings or by plant division. The easiest method of propagation is by plant division.

How to propagate Smilax Asparagus Fern by plant division

Divide the Smilax Asparagus Fern rhizome into sections by cutting with a sharp, clean knife or a pair of scissors.

Pot the sections into individual pots in moist, free-draining potting soil.

Place the pots in a warm, well-lit place and maintain the soil moist until new growth begins.

Allow the new Bridal Creeper to be well established, after which you can begin routine care.

Asparagus asparagoides Problems

Smilax Asparagus Fern (Asparagus asparagoides) problems include yellowing leaves, dropping leaves, leaf spots, plant death, diseases and pests among others. Read on for more on these problems and how to solve them.

Leaves yellowing and dropping

There are many and varied reasons for yellowing and dropping leaves in Smilax Asparagus Fern.

One reason why Bridal Creeper may turn yellow and lose leaves is too little light.

Move the plant to a brighter spot where it can receive medium to bright, indirect light or instal a grow light if the natural lighting is not adequate.

The second reason for yellowing and dropping leaves in Smilax Asparagus Fern is that the soil has been allowed to dry out.

Water the fern liberally during the growing season while allowing the top 2 in. of soil to dry out between waterings to keep the soil moderately moist through out.

Decrease watering during the cold period to maintain the soil slightly moist but do not allow the soil to dry out completely.

The third possible cause of yellowing and dropping leaves in Bridal Creeper is too high temperatures.

Maintain an average room temperature within the range of 12-28⁰C as constantly high temperatures can damage the fern.

Brown leaf spots

Brown leaf spot marks in Smilax Asparagus Fern are sunscorch marks caused by exposure of the fern to hot direct sunlight.

Position the Bridal Creeper in a more shaded place, away from direct sunlight but ensure it is receiving medium to bright, indirect light.

Plant dying

The cause for unexplained death in Smilax Asparagus Fern is root-rot disease which is promoted by soggy soil brought about by poor soil drainage.

Bridal Creeper has thick, tuberous roots which store water. Therefore, soggy soil will cause the roots to rot.

Ensure that the soil is loose, free-draining and the pot has a drainage hole to avoid getting soggy soil. Read on how to treat root-rot disease in houseplants.

Pests

Common pests in Smilax Asparagus Fern are Spider Mites, Aphids, Mealy Bugs and Whiteflies whose infestation is promoted by either overwatering or underwatering.

Keep these pests away by maintaining the soil moderately moist during the growing period and slightly moist in the cold period but never allow the soil to dry out completely. Read on how to identify and get rid of pests in houseplants.

Diseases

Apart from root-rot disease, Smilax Asparagus Fern is also prone to crown-rot and stem-rot which is prevalent in overwet, poorly ventilated conditions.

Isolated the affected fern to prevent spread of the disease to the other houseplants and treat it appropriately for crown-rot and stem-rot disease.

Improve ventilation and make sure that there is free air circulation for the Bridal Creeper.
