Spike Moss (Selaginella) Care & Growing Guide

Spike Moss Care & Growing Guide

1. Light Requirement

If you are going to keep this plant indoors, you’ll want to put it in an area that receives bright filtered light. You can keep this plant close to a curtained window that faces the sun in the afternoon. Adequate sun is crucial for growing this plant and keeping it as healthy as possible.

You can keep this plant in partial shade, provided that it gets lots of light in the morning hours. You don’t want to expose this plant to bright direct afternoon light, as it will end up scorching the leaves. This can lead to a lot of damage to your plant within a matter of days or even hours.

2. Water

You will have to keep the soil this plant is in moist but not drenched. It is imperative that you don’t give it too much water at once, or water it too frequently. This can lead to root rot, which could mean the end of your plant altogether.

If you are ever not sure whether or not you should water this plant, all you have to do is just feel the soil. If the soil feels moist at all, you will want to put off watering it for a little bit. It’s always better to be safe than sorry when it comes to watering these plants.

If this plant gets too dry, it could actually become dormant. You can, however, bring it back to life by simply giving it a drink of water. Make sure that you don’t give it too much water though, as this could cause root rot.

3. Climate

Spoke moss can be grown in a variety of climates due to its highly adaptable nature. In fact, this plant has no problem coping with colder weather. You can grow this plant in USDA hardiness zones of 6 or higher.

4. Soil

It is a good idea to grow this plant in peat moss-based soil, as it is well-draining but still manages to retain water effectively. This is by far the best soil to grow your plant healthy right from the start.


5. Temperature

It is best to maintain a temperature range of 50 to 75 degrees Fahrenheit for Spike Moss plants. While these plants can deal with colder temperatures fairly well, it is better to keep them warm if at all possible. This plant can be outside in temperatures all the way down to 40 degrees Fahrenheit without any issues.

One of the best things about this type of plant is that it can be kept outside throughout the entire year in most regions. If you decide to take this plant inside at any point, make sure that you don’t keep it by any heating vents. This could dry the plant out to the point where it cannot recover.

This plant can withstand cold temperatures of up to 0 degrees Fahrenheit, which is impressive to say the least. The fact is that you won’t find many other plants that are quite as durable and adaptable as this one.

6. Repotting

Repotting is not necessary very often with Spike Moss. You’ll want to put it in a container that is about one size larger when it starts to outgrow its current container. You should only have to do this once every couple of years or so.

7. Speed of Growth

Spike Moss grows fairly quickly in warm weather with bright sunlight, but it has a resting period in the winter months.

8. Height and Spread

These plants can grow anywhere from 7 to 9 inches tall with a spread that is just about the same.

9. Flowers

Because the Spike Moss is a spore plant, it actually doesn’t produce any flowers.

10. Trimming

When you want to control the size of your spike moss, you can cut the stems back. Just pinch the stems back, and the plant will produce new growth at its base. Make sure that you take care of any dead or dying stems or foliage as well.
