Taxonomic Information

Appearance

Microgramma ferns are known for their unique and elegant appearance. The fronds of the ferns are elongated and have a fishbone-like shape that gives them a striking and distinctive look. The fronds are typically bright green and leathery, and they can grow up to 1 meter in length. The ferns also have a rhizome that is covered in brown scales, which helps to anchor the fern to its substrate.

Care Guide

Microgramma ferns are relatively easy to care for and make great houseplants. Here are some tips for taking care of your Microgramma fern:

Water: Microgramma ferns prefer to be kept consistently moist, but not soaking wet. Water your ferns when the top inch of soil feels dry to the touch.

Fertilization: Fertilize your Microgramma ferns once a month during the growing season with a balanced, water-soluble fertilizer.

Soil: Microgramma ferns prefer well-draining soil that is high in organic matter, such as a peat-based potting mix.

Sunlight: Microgramma ferns prefer bright, indirect light. Avoid direct sunlight, as it can scorch the leaves.

Hardiness Zones: Microgramma ferns are not cold-hardy and should be kept indoors in temperatures between 60-80°F.

Common Pests & Diseases

Microgramma ferns are relatively pest and disease-resistant, but they can still be affected by a few common problems. Here are some of the most common pests and diseases that can affect your Microgramma fern:

Scale insects: Scale insects can be a problem for Microgramma ferns, especially if they are grown in low-humidity environments. Look for small, brown or yellow bumps on the leaves or stems of your ferns, and treat them with a horticultural oil spray.

Mites: Mites can also be a problem for Microgramma ferns, especially if they are grown in hot, dry environments. Look for fine webbing on the leaves or stems of your ferns, and treat them with a miticide spray.

Fungal diseases: Microgramma ferns can be susceptible to fungal diseases like root rot and leaf spot. To prevent these problems, make sure your ferns are planted in well-draining soil and avoid getting water on the leaves.

Habitat

Microgramma ferns are native to tropical and subtropical regions around the world, including South America, Africa, and Southeast Asia. They are typically found growing on trees, rocks, or other substrates in humid environments like rainforests and cloud forests. Some species of Microgramma ferns are epiphytic and grow on other plants, while others are terrestrial and grow in soil.
