Yes, ferns have the capability to do very well outside, especially if you live in a tropical climate that is very humid.

You should water your ferns a maximum of once or twice a week if it hasn’t been raining outside. Outdoor ferns tend to thrive in a shaded area where the soil can remain moist for longer periods of time.

As a rule, they prefer 1 to 2 inches of water a week, but this will vary depending on the soil and the growth rate.

Signs Of Improper Watering

Getting the right balance of water can be a challenge when you first become a plant parent and navigating your watering routine might take a little while to figure out.

However, there are a variety of different signs that indicate you are improperly watering your ferns and should be on the lookout for.

The signs that you’re underwatering your ferns include:

Leaves turning brown – If the leaves of your ferns are turning brown, then this is a good indication that you’re underwatering your plant and it is thirsty.

Crispy leaf edges – A clear sign of dehydration in your ferns is when the leaf edges feel dry and are crispy to the touch.

Leaves dropping – If the leaves on your fern begin falling off, it is highly likely that you’re underwatering it.

Dry soil – You can usually tell if your plant needs a good drink by simply touching the soil. If it is bone dry to the touch, then it is likely dehydrated and needs more water.

Consider using a moisture meter to make sure your plant’s soil isn’t too dry or too moist

The signs that you’re overwatering your ferns include:

Yellow leaves – Leaves turning from green to yellow and falling are a big sign that you are overwatering your plant.

Wilting leaves – The ironic thing about over-watering is that it can also cause wilting the same as underwatering does. This comes down to the fact that the soil is waterlogged and the roots are starved for oxygen.

Waterlogged and wet soil – Another clear indication that your fern has been overwatered is when the soil is oversaturated and becomes waterlogged. Always make sure that you check the moisture of the soil with your fingers before you water your ferns.

Disease – If you overwater your soil, fungi may form on the surface of the soil.

Squishy texture – When you feel the leaves, your plant will have a distinct squishy feel to it when you feel it with your fingers.

Tips on how to take care of outside ferns

Water Ferns Correctly

When it comes to watering your outside ferns, always make sure that you check the soil before you do so. Simply place your fingers in the soil and check the moisture level, as this can prevent you from under watering or over watering your plant. 

You will also want to make sure that you direct the water stream at the roots over the fronds. If you fail to do this, you can end up damaging the plant.

Keeping ferns outside means that they are exposed to the elements all of the time. You will also need to make sure that you adapt the amount of water that you give your ferns in accordance with the weather conditions.

If it’s been a particularly rainy week, then you might need to water it less. On the other hand, if you live in a particularly hot country and it’s been very dry and hot, you might need to water it more than you normally would.

Trim Damaged Fronds

If your fern has become damaged over time due to improper watering or the natural predators that it may encounter outdoors such as slugs or diseases, you will have to cut back any damaged fronds.

While these diseases are rare, you will want to make sure that you cut back any damaged or diseased fronds with a pair of garden shears. Not only will this prevent the disease from spreading to other plants, but it will also help to keep the integrity of the plant.
