How to fertilize Alligator Fern

Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Alligator Fern after it doubles in size or once a year—whichever comes first.

Alligator Fern prefers for the soil to dry out between waterings and should be watered regularly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.

Toxicity
Greg does not have confirmed data on this plant’s toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, it’s always best to consult a medical professional.
If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA at US (888) 426-4435.
Humidity
Alligator Fern enjoys lots of humidity. Provide humidity for your plant by watering regularly and thoroughly, since plants absorb most water through their root system rather than their leaves. They may also benefit from being placed next to a humidifier.
Soil
Alligator Fern is very sensitive to dry soil, so choose a potting soil that retains moisture. A good soil will still drain well and contain lots of organic matter such as coco coir or sphagnum moss.
Fertilizer
Alligator Fern should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!
Native Region
Alligator Fern is native to Temperate and Tropical Old World.
Propagation
Alligator Fern can be propagated by division into new individual plants.
- Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
- If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
- Pot up the new plant in well-draining soil
- Repot the parent plant back into its original pot

What other plant parents say









It is a pretty fern with limey green coloured and interesting patterned leaves. It does need some humidity though the ends of the leaves will go crispy without it. I have grouped my humidity loving plants together to form a micro climate which seems better for my crocodile fern.
