_{Recommended Potting Mix}

Most ferns flourish in well-aerated, consistently moist potting soil. Still, one thing fern varieties enjoy is acidic soil. So, while it can tolerate different soil types, the critical thing is aeration and drainage.

So add that organic matter with some perlite to the mix. Doing this provides ferns with soil aeration and drainage to keep them thriving. Whether you have one in a hanging basket or growing ferns outside, this remains important.

The organic matter provides a slow-releasing supply of nutrients to keep them smiling and happy.

_{Lighting Demand For Fern Fronds}

Growing ferns indoors all comes down to choosing the correct location. The same applies when planted outside. As ferns grow in tropical regions on forest floors, they do not need full sun to flourish.

They can thrive in bright indirect light for up to six hours. Still, the greenery can also thrive in low light and is best to protect them from bright light as the leaves can turn yellow.

So for optimum growth, ferns love hanging baskets or growing next to tree trunks without too much sun.

_{Watering Needs For Ferns}

Okay, these vegetation are heavy drinkers (gulp, gulp, gulp) and need frequent watering compared to other house plants. But, you can water them moderately when you notice the top few inches of the earth drying out.

The reason to keep the soil moist is due to a high rate of water transpiration taking place through the leaves. Many indoor ferns have feathery textures leaf, and a lot of water is lost in the atmosphere, causing a loss in moisture.

So please do not leave your babies without water for too long as it starts to shed those gorgeous leaves. Hence, the rule of thumb is to feel the ground, and if the top two inches are dry, water your fern.

Another important note, yes, essential, is to provide them with room temperature water to prevent shock.

_{Ideal Temperature & Humidity}

You can quickly grow fern varieties indoors as there are average temperatures similar to growing in tropical environments. The best growing temperature is 65-80°F (18-26°C).

While it is cold-hardy, it cannot tolerate temperatures of 20-30°F (-1 to -7°C). So if your greenery stands on the patio and it gets icy cold, we recommend bringing them in.

Besides, ferns thrive in high humidity and help to provide them with a pebble tray or humidifier placed close to them.

_{Necessary Fertilizer For Your Varieties of Ferns}

While fertilizing is not a must, you can provide them with mild dosages of feed once in a while for fast growth. In addition, you can use a liquid houseplant fertilizer and best water them before feeding to reduce the risk of root burn.

_{Fern Varieties Propagation}

The fantastic thing is propagating your fern varieties using division or the seed (spores) to grow new plants. Still, the asparagus or Plumosa you can only multiply with spores. That is if you can get your hands on them.

You can do this when it blooms and bears fruits. Unfortunately, that is a rare occasion. Check out this handy guide on how you can grow them from the spores. Of course, the best way is to use division and do this by identifying the clusters and tubers.

You can pot them in the same potting mix as your mother plants. Make sure the air pockets are removed from all sides of your vegetation and water it well. You can then cover the tubers with a plastic bag and leave them for a week or two to speed up the process.

_{USDA Growth Zone}

In the USDA hardiness zones 9 to 11, you can grow your ferns outdoors all year round. But if you live in cooler climates, you need to bring them indoors to keep them protected in the winter.

_{Potting and Pruning}

Your ferns only need a small to a medium-size pot, but some varieties need a large pot depending on their growth. Most ferns love to be root-bound, and adding a layer of rocks to the bottom is outstanding in providing the correct drainage.

Doing this also prevents the drainage hole from getting clogged. Now, ferns can grow out of place and might need pruning back to keep them maintained. But, again, the best is to remove the damaged fronds, and annual pruning helps with the growth.

So the best time to prune is when you repot your baby in spring or summer.

Fern Indoor Plants Diseases & Pests

Your ferns do not get infected by many pests or diseases. Still, it does depend on the species you have. The main concern is root rot and that the plant is toxic to pets. Other things you need to keep an eye on is:
