The Plumosa Fern often called the Asparagus Fern is actually a climber, and often grows in pots and hanging baskets. It has feathery leaves and thorny stems.
The leaves give the Plumosa Fern a light lacy appearance. It has tiny white flowers in Spring followed by small black-berries and will grow well outdoors in many climates, growing best in a lightly shaded position.
It really only requires minimal care so it is a good plant for the first-time gardener.
How to Care for Plumosa Fern
Keep your plant moist, and in a slightly shaded spot. It prefers well-drained soil. If you have your plant indoors, keep a spray bottle of water handy to mist the leaves.
Hanging baskets of Plumosa Fern look very cool and pretty in a conservatory, sunroom area, as the plant will trail down over the sides of the basket. Your plant will thrive in average room temperatures ( not too hot).
What Does your Plumosa Fern Require?
Light Requirements for Plumosa Fern
Either inside the house not in direct sunlight or outside in a slightly shaded sheltered position, no frost. Your plant will require regular watering.
If you have very cold winters, your plant will probably die off and return in Summer.
We have established that the plant does not like to get really cold, but it does not thrive in extreme heat either but does favor high humidity.
The plant is able to tolerate full sun for a period of time, but this causes the foliage to turn yellow and doesn’t look nice.
Plant in well-drained soil, give your fern a dose of Epsom Salts as liquid fertilizer, this will make the leaves a richer shade of green ( due to the magnesium content of the product) This works particularly well indoors, making your plants appear really healthy and glossy.
If you have an indoor Plumosa Fern give it one to two inches of water per week. If you have your plant in lighter more sandy soil it will require more water.
Keep misting the leaves in between watering to keep the humidity content higher.
How to Water your Plumosa Fern
If you can, take your plant outside once a week, and hose the whole plant down. This removes any dust from the leaves, that has lodged there, and will keep it much cleaner looking.
If you can’t take the plant outside keep misting the leaves with the spray. Check your plant to ensure it is always a bit moist.
How to Fertilize your Plumosa Fern
If your fern becomes yellow, you may be giving it too much fertilizer. In Spring only, give it some indoor plant fertilizer. If it is an outdoor plant compost and mulch will keep it moist and prevent overwatering. Try the Epsom Salts to green it up again.
