Asparagus Setaceus

Asparagus setaceus should be watered regularly, allowing the top few inches of soil to dry out before watering again. This plant likes consistently moist soil, but not soggy. Too much water will cause the plant to root rot, and too little water will cause it to wilt and the leaves to turn yellow.

Asparagus setaceus prefers medium light conditions, such as an east-facing window or a bright, north-facing window. It can also tolerate filtered sunlight in partial shade. If the plant gets too much sunlight, or if it does not get enough, its leaves will yellow and may even drop off. It will also be more susceptible to pests.

Asparagus setaceus prefers temperatures that range from 65°F (18°C) and 80°F (27°C). Temperatures outside of this range may cause the plant to go dormant or drop leaves.

Asparagus setaceus prefers a higher level of humidity and can be prone to problems like spider mites and mealybugs if the humidity is too low. To increase the humidity, you can mist the plant regularly, place a humidifier nearby, or place the pot on a humidity tray. You can also place the pot in a saucer of pebbles and water, making sure the water does not touch the bottom of the pot.

Asparagus setaceus prefers a well-draining soil. A good potting soil for this plant should have some peat moss and perlite in it, as well as some organic matter, such as compost or leaf mold. The soil should also be slightly acidic, between 6.0 and 6.5.

Asparagus setaceus should be fertilized during the spring and summer months with a balanced fertilizer. Use a slow-release fertilizer about every two to three months, depending on the plant size. If using a liquid fertilizer, feed every month at half the recommended application rate.

Asparagus setaceus can be prone to pests, such as aphids, spider mites, mealybugs, whitefly, and scale. Aphids and mealybugs can be dealt with by spraying the plant with a neem oil mixture. Spider mites can be dealt with by decreasing the humidity, and whitefly and scale can be controlled with an application of insecticidal soap or liquid horticultural oil. If chemically controlling pests is not an option, you can physically remove them with a cotton swab or q-tip dipped in rubbing alcohol.

Asparagus setaceus should be repotted every two to three years, during the spring or early summer. When repotting, choose a pot about one to two inches larger than the current pot and use well-draining soil. Plant the root ball at the same soil level as it was previously planted, and water sparingly until new growth has started.

Asparagus setaceus should be pruned regularly to keep it looking full and healthy. Snip off yellowing, dead, and damaged leaves, and remove long, leggy stems to shape the plant. Pruning it regularly will encourage the plant to produce new growth and will also keep it from becoming unruly. If pruning all at once, do it sparingly to prevent shock.

Asparagus setaceus does not need to be mulched, however, mulching the bed or pot where the plant is growing can help to retain moisture and can also provide additional nutrients to the soil. Organic mulches such as wood chips or bark nuggets are good choices.

Asparagus setaceus can be easily propagated by division. When the plant has grown too large, carefully dig it up and separate the root ball into smaller clumps. Plant each clump in a larger pot with well-draining soil. Water sparingly and ensure it is in a bright, indirect light.

Asparagus setaceus does not need to be staked or supported, but for plants over 12 inches tall or top-heavy specimens, a bamboo or wooden stake can be helpful. If using a stake, make sure that it is not too tight against the stem and that the ties are loose enough that the stem can still move.

Asparagus setaceus does not need a rest period and can be kept healthy year round. If it is looking tired or lackluster, move it to a bright area with indirect light and adequate humidity.

Asparagus setaceus is non-toxic to cats, dogs, and horses, according to the ASPCA.
