Pteris altissima Poir. is not a heavy feeder, but it still requires regular fertilization to thrive. You can use a balanced liquid fertilizer or slow-release granules during the growing season, which is usually from spring to fall. Avoid fertilizing the plant during the winter season when it is dormant.
When fertilizing Pteris altissima Poir., you should follow the manufacturer's instructions or use a diluted solution to avoid burning the roots or foliage. You can fertilize the plant once a month or every two months, depending on its growth and health.
Pruning of Pteris altissima Poir.
Pruning Pteris altissima Poir. is not necessary, but it can help maintain the plant's shape and size. You can remove any yellowed, diseased, or damaged fronds using clean pruning tools. You should also cut off any old fronds that have turned brown or lost their vibrancy to encourage new growth.
Pruning can also help improve air circulation around the plant, which can prevent fungal diseases and pests. You can perform pruning at any time of the year, but it is better to do it during the growing season when the plant is actively growing.
Propagation of Pteris altissima Poir.
Pteris altissima Poir., commonly known as the 'Tassel fern,' is a beautiful ornamental fern that can be propagated through spores or division of the clumps. Here are the detailed propagation methods for Pteris altissima Poir:
Propagation by spores
The spores of Pteris altissima Poir. can be collected from mature fronds, and a single frond can yield thousands of spores. Collect the spores when the fronds have turned brown and dry. You can do this by placing a brown paper bag over the frond and shaking it gently. The spores will fall into the bag.
You can propagate Pteris altissima Poir. from spores by the following steps:
- Sterilize a small pot, soil, and spores by baking in an oven at 180°F (82°C) for an hour.
- Fill the pot with a well-draining, sterile soil mix.
- Sprinkle the spores on the soil surface evenly. Do not cover the spores with soil as they need light to germinate.
- Cover the pot with plastic wrap to maintain high humidity levels.
- Place the pot in a warm, shaded area
- Mist the soil surface frequently to maintain moisture.
- Within 4-6 weeks, small, green, heart-shaped gametophytes will appear. These gametophytes are the first stage of fern growth.
- Once the gametophytes have established, transfer them to a larger pot with well-draining soil.
- Keep the young ferns in a warm, shaded area and continue to mist the soil frequently until they become established.
Propagation by division
Pteris altissima Poir. can also be propagated through division of clumps. This method is simple and easy to do, and it is best done in early spring or late winter before new growth appears. Here are the steps to propagate the Tassel fern through division:
- Gently remove the fern clump from its pot, and then remove excess soil from the roots.
- Use a clean, sharp knife to divide the clump into several smaller sections. Each section should have a few fronds and a good root system.
- Pot the divided sections into individual pots with well-draining soil mix.
- Keep the pots in a warm, shaded area and water frequently until the new plants become established.
With these simple propagation methods, you can grow and propagate the beautiful Pteris altissima Poir. easily at home.
Disease and Pest Management for Pteris altissima Poir.
Pteris altissima Poir. is a fern species commonly grown for its ornamental foliage. However, like all plants, it is subject to a range of diseases and pests that can harm its growth and appearance. Therefore, it is essential to understand the common problems that affect this plant and how to manage them effectively.
Common Diseases
The following are some of the common diseases that can affect Pteris altissima Poir.:
- Fusarium wilt
- Rust
- Leaf spot
Fusarium wilt is caused by a soil-borne fungus that attacks the plant's roots, causing yellowing, wilting, and eventual death. Rust is characterized by the appearance of rust-colored spots on the foliage, which can cause defoliation and weaken the plant. Leaf spot is caused by a fungal infection that leads to the appearance of circular, brown spots on the leaves.
Disease Management
To manage these diseases:
- Use disease-resistant cultivars when available.
- Remove infected plant material promptly to prevent the spread of disease.
- Avoid overhead watering to reduce foliage moisture, which can contribute to fungal growth.
- Ensure proper drainage in the plant's growing medium to reduce the risk of Fusarium wilt.

Common Pests
Some of the common pests that may harm Pteris altissima Poir. include:
- Spider mites
- Mealybugs
- Whiteflies
Spider mites are tiny pests that feed on the plant's foliage, causing yellowing and stunted growth. Mealybugs are also small, but their white, cottony appearance makes them more noticeable. They feed on the plant's sap, which can lead to wilting and leaf drop. Whiteflies are small, flying insects that suck on the plant's sap, causing leaves to yellow and become distorted.
Pest Management
To manage these pests:
- Use insecticidal soaps or horticultural oils to control pests when they are present.
- Apply treatments according to label instructions and handle chemicals safely.
- Use sticky traps to capture flying pests such as whiteflies.
- Keep the plant in good health with proper watering and fertilization practices, to reduce its susceptibility to pest infestations.
