Remember, these are not true ferns that spend loads of time sunbathing. As it is part of the lily family, it prefers bright indirect light. Those small leaves are vulnerable and dry out fast.

So as an indoor houseplant, never place it in direct sun or too close in a south-facing window. Preferably put it at an east-facing window to enjoy the sun in the morning.

Guess what? You can place the Sprengeni on your desk as it thrives in artificial light.

Asparagus Ferns Soil Requirement

Go with something rich such as all-purpose soil and a good choice. To increase the nutrient levels and acidity, it also helps to add peat moss to the mix. Your plant will love it, and you can plant it in containers with enough drainage holes.

Grown outside, it also enjoys rich, well-drained soil. Doing this allows for breathability in the tubers keeping your fern plant as happy as it can be.

Asparagus Fern Care Water Requirement

Okay, now do not go and drench the plant with water. It prefers light water regularly and can tolerate drier soil to an extent. So keep things even as it has delicate leaves that damage easily. Another thing this plant is very sensitive to is chlorinated tap water. Thus, if you do use tap water, leave it to stand overnight before watering your plant.

Now, this is where things become tricky-keeping your foliage hydrated. Boy, it takes effort as it thrives in humidity. Occasionally mist your Asparagus ferns but focus on the arching stems. A tip is to check if the plant becomes droopy or turns brown and a sign it needs more water. When outdoors, keep it well-watered to prevent the ground from drying out completely.

Fern Asparagus Temperature and Humidity Requirement

The best temperature for your Asparagus fern is one that is warm, around 70-degrees F but not below 55-degrees F. One thing the Densiflorus Sprengeri, another variety of Asparagus and both love, is high humidity. A tip to do this is to spray it weekly or place it on a pebble tray to keep the leaves in tip-top shape.

The nice thing is a pebble tray looks attractive and adds some decor touch to any home.

Asparagus Fern Fertilizer Requirement

Okay, your body needs nourishment, right. The same goes for the Asparagus Densiflorus or any other varieties of Asparagus plants. You can use a balanced fertilizer if it stands inside the home, but we recommend diluting it to half strength to prevent burning the leaves and roots.

During the summer, provide it with weekly feedings but halt when in winter as it only needs feeding once a month.

Asparagus Fern Potting

Now, one thing the Asparagus fern plant does not mind is feeling a bit pot-bound. So give a clap of the hands as you only need to transplant the fern plant every two years. A great tip when doing this is to divide the Asparagus ferns into big clumps. Also, make sure to take multiple of the roots when you divide them.

Take your plants and place them in the correct sized pots to help retain new growth. The reason is that as a houseplant they are slow spreaders. Now the exciting news is you can grow your Asparagus fern from seeds.

Asparagus Fern Diseases & Pests

Yes, we can already see your face and start to stress that your fern will die. However, there is no need to fret as we have all the inside news on the Asparagus fern care to resolve diseases and pests.

Yellow Needles or Fronds

This is a clear sign that your Asparagus fern is dehydrated caused by too much sunlight or not regular watering. While it might not rejuvenate new growth, new ones can appear at the base if you improve the growing condition. We recommend providing your plant with only two hours of sunlight and only allow the top third of the soil to become dry.

Yellow Needles Dropping Off

Yes, you want to cry as you feel your Asparagus ferns dying. But there is some light ahead in some specimens. Suppose the stems are crisp, prune them an inch from the tuber surface ( it looks like a potato), and place them in a transparent bag with small holes. Keep the soil moist with indirect light. You will notice new arching stems developing, showing it is recovering, yeah. Keep it sealed for another month before releasing it back to fresh air.

Browning Needles

This is another sign of dehydration but can also be of dry air. Remove your plant if it is too close to a heater and provide it with a pebble tray to improve the humidity.

Root Rot

Happens when your Asparagus is in dark environments too long, and the soil remains wet. You notice the leaves yellowing, and it has stopped growing, leading to a brown rotten base. The best for your foliage is to remove it from the container to inspect the health of the roots.

If the roots are yellow, you can still save your plant by placing it in fresh soil. Yet, if it is mushy and brown, you need to take action now. First, remove the mushy roots while leaving the healthy ones alone. Then, clean the container with soapy water to remove harmful pathogens.

Rinse the roots with lukewarm water and plant in the sterilized container.

Some of the common pests you can look out for are:

  • Spider mites
  • Aphids
  • Mealybugs

To rid your Asparagus ferns of these insects, you can use insecticidal soap.
