Toxicity
Delta Maidenhair Fern is not known to cause harm to humans or pets. Regardless, if you, a family member, a cat, or dog has ingested any plant material, please consult a doctor or a veterinarian.
Humidity
Delta Maidenhair 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
Delta Maidenhair 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
Delta Maidenhair Fern grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!
Native Region
Delta Maidenhair Fern is native to Worldwide.
Flowers
Delta Maidenhair Fern does not flower.
Growth Pattern

Growing Outdoors
USDA Hardiness Zone

Propagation
Delta Maidenhair 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
Yellow Leaves
Yellow leaves aren’t always a reason to panic, and can be a normal part of a plant’s life cycle. Unless brand new leaves are turning yellow or all the leaves change color at once, it’s likely just your plant shedding old leaves.
Overwatering and root rot are the most likely cause of problems in Delta Maidenhair Fern, since they are sensitive to wet soil. The leaves may also appear to be curling or drooping. Less often, yellow leaves are caused by underwatering, nutrient deficiencies, or pests.
Replace soggy soil with fresh, dry soil and download Greg to make sure your plant never gets overwatered again!

What other plant parents say










my first houseplant. WHEW. i love her, as all plants have personalities. i certainly don’t REGRET buying her because it’s made every other plant i’ve gotten seem very easy in comparison.
These plants are gorgeous if you’re a fern lover like me. They do very well in bathrooms as long as they have windows, and they thrive in humidity. i’ve found that watering once a week works well, and that they love bright, indirect light.
i’m pretty strapped for humidity because my bathroom has no window, so i have her near my dishwasher which releases steam as it washes, and it seems to work okay temporarily, but once i get a humidifier for my room, i’ll bring her into the rest of the gang
TLDR;
sort of a diva plant. would reccomend for someone with a little experience.
grow sorta fast in good humidity and bright indirect light. Don’t overwater but don’t overthink it like i did lol. (watering once to twice a week is my recommendation). very sweet-personality plant.
