Signs to know a dying Asparagus Fern

If you are one of the thousands who grows asparagus ferns, you probably want to know why they might be dying or show symptoms of death.

1). Lack of adequate water

The truth is that all ferns, especially the asparagus fern, will die from the same cause, the lack of water. This is common for all ferns, as they are mostly epiphytes that grow on water.

Water helps to regulate growth and spread of fungi. Without sufficient water, fungi will overgrow and infect the leaves, eventually causing the death of your asparagus fern.

As a matter of fact, the only way to prevent this from happening to your fern is if it’s completely dried out. The best way to do this is by providing it with an adequate amount of water. Some ferns are naturally asparagus resistant, and can survive in as little as 2% water, but most require an additional five to ten percent water.

So if you have a drier climate, make sure you provide your fern with as much water as possible, as humid air makes the fungal diseases more severe.

In addition, keep in mind that the primary threat posed by the fungus that attacks your fern is actually the penetration of the spores into the new growth of the plant.

So, to prevent the fungal growth from spreading, make sure that there are not too many leaves on the plant. One way to ensure this is to thin the plants as they grow, since the larger the leaves of the plant, the more chances there are for the spore to penetrate into the new growth.

2). Does it turn out to be sunny?

In some cases, the leaves of your fern might not always stay in direct sunlight, especially in the summertime.

It can be difficult to give your fern sufficient light, but it’s important to try. If you have a shady spot in your yard, you may want to consider growing your fern in that spot instead of in full sun.

Ferns will do well even in shaded areas; just remember to make sure that the soil has enough moisture to allow the new growth of the plant to occur. Ferns in full sun tend to become stressed by the heat and can die.

3). Is your Asparagus fern suffering from what appears to be a leaf disease?

Sometimes, infected leaves of your Asparagus fern will turn yellow, brown, or black. The foliage may also begin to droop and curl up.

Usually, however, the symptoms are milder than this and the leaves rarely die. You may also notice that the underside of the stems may be discolored, moldy, or suffering from a powdery residue that clings to the foliage of the plant.

4). Does your Asparagus fern appears to be losing its leaves?

If the leaves of your Asparagus fern are not growing, it’s due to the loss of the tuberous roots.

The roots, when they die, are unable to absorb enough water to keep the foliage green and healthy. You should water regularly but remember to only do so when the soil is wet.

How to revive a dying asparagus fern

Reviving a dying asparagus fern can be a little tricky, to say the least. This plant is not very common in the United States, and it is not edible. If you really want to try to grow one, you need to find a source that grows it natively.

Luckily, as of right now, you can pretty much find any type of fern in the southern United States.

The only difference between this species and other types of plants in your area is that they are not native, so the asparagus fern is not going to be quite as hard to find.

In a small container, mix in a little perlite to give the pot a darker appearance and give it more of a cushioning effect.

Humidity of the area

In order for the asparagus fern to survive, it will need some humidity. You can mist the plants from the top by using a watering can, but this will only work temporarily. You need to give the roots of the fern water regularly.

Final thoughts

Water your fern well when it starts to look wilted, but do not overwater it because that will encourage the plant to die even more.

If you have a hole in your ground that your fern can fit in, all you need to do is add some water and let it sit.
