Japanese painted fern is virtually pest-free, no matter what environmental conditions you are growing yours in. However, some curious intruders like caterpillars, slugs, or snails may bother your plant once in a while. These pests usually feed on the leaves of Japanese painted ferns and can badly damage the foliage with time.
The best way to protect your fern from this problem is to create a natural barrier around its base. The barrier can consist of either rocks or mulch. If the pests have already infested your Japanese painted fern, you must first remove them with bare hands. After this step, you should apply neem oil on the leaves until you see no trace of the pests.
Planting Japanese Painted Fern
One of the most important demands that Japanese painted fern has is the type of soil in which it will grow from now on. As a rule, the plant does well in soil that comes with very good drainage. If you do not plant yours in well-draining soil, some issues like fungal diseases or root rot may occur at any moment.
Moreover, this fern will appreciate neutral to very acidic or slightly alkaline substrates that are rich in nutrients and organic matter.
A simple trick to provide your Japanese painted fern with lots of nutrients is to add compost into the soil before planting.
For best growth, we warmly recommend you amend the soil a few weeks to months before planting your Japanese painted fern.
As long as you grow your Japanese painted fern in humusy, nutrient-rich soil, you will not have to think too much about fertilizers. In fact, the plant will do just fine if you feed it with a balanced pelleted or liquid fertilizer at ½ strength once every year in spring.

Watering Japanese Painted Fern
Japanese painted fern is one of those companions that thrive with constant moisture. Still, it will not benefit from soggy conditions or waterlogged soils. This plant is susceptible to root rot, so over-watering is something you will surely want to stay away from. And it is not as difficult as you might think to do so!
First things first, keep in mind that you should always check the growing medium of your Japanese painted fern in-between waterings. During the warmer seasons, this plant will require another drink when the top half of the soil feels dry to the touch. In autumn and winter, however, the fern will do just fine if you provide it with water whenever the soil has dried out completely. That’s all!
Propagating Japanese Painted Fern
Japanese painted fern typically spreads through rhizomes and may even fill your garden with lots of colours with time. However, this spreading occurs very gradually, so you will have to be more patient if you want a garden full of this beauty. Or maybe not!
Luckily, this particular spreading habit of the Japanese painted fern makes it excellent for propagation. If you have not done this before, do not worry! The easiest way to propagate your Japanese painted fern is through division in spring. Being one of the most effective methods of propagation, the division will show spectacular results in literally no time.
Once the spring shows its warmth, you can dig your Japanese painted fern out of its growing medium using a good old shovel. After this step, all you have to do is divide its rhizome into as many sections as you can, then replant each of them into its permanent spot.
The number of sections may vary depending on the size of your plant. In general, you can obtain two or three healthy small Japanese painted ferns. When the transplanting process is over, make sure you water each Japanese painted fern well. If you happen to have too many Japanese painted ferns around you can always gift some of them to your fern-loving family members or friends!
