Asparagus plumosus, also known as Asparagus Fern, is a small shrub native to South Africa, typically growing between the heights of 2-5 feet tall. It's an attractive evergreen perennial usually grown as an ornamental plant, due to its beautiful foliage. It is best grown in USDA Zones 9-11 and requires moderate water in order to stay healthy and lush.
If you are looking to grow Asparagus plumosus as a houseplant, then it needs a bright spot with some shade. For warmer climates, regular watering is needed to keep the soil moist, but not wet. To keep the soil from drying out, you can use a plastic pot or pot your plant in a terracotta pot with a plastic liner. Since the shrub prefers a moist environment, adding some mulch on top can help retain moisture and reduce the need for frequent watering.
For colder regions, where the soil freezes during winter, it can be tricky to keep Asparagus plumosus going. To start with, you must grow it in a pot that is filled with good potting mix. This will help drain the soil quickly and ensure that water doesn't get frozen in the pot. It is also important that you use a protective covering, such as a plastic sheet, to protect the foliage from cold winds. Watering in winter should be kept to a minimum as too much water can damage the roots. Moreover, avoid fertilizing in winter and wait until the spring to feed your Asparagus Fern.
