Autumn Fern Indoors (Dryopteris erythrosora)
Features
The Autumn Fern gets its name because its fronds take on beautiful autumn-like coloration in both spring and autumn. Fern’s soft texture and graceful form lend a peaceful feeling to any setting. A great choice for adding a natural touch to a porch, patio or deck as well.
Uses
Indoors in a pot or hanging basket. This hardy fern can also be planted outdoors and is ideal for woodland settings and borders.
Plant Feed
Apply a balanced liquid fertilizer monthly.
Watering
Water every 5 to 7 days depending on light and temperature. Keep soil evenly moist, but not soggy.
Soil
All-purpose potting mix.
Basic Care Summary
Thrives in ordinary, well-drained soil. Water as needed to keep soil evenly moist, but not wet.
Planting Instructions
Start with a good quality, commercial potting soil. These are usually lighter in weight than topsoil, sterile and pest-free. Many are available with a mild starter fertilizer in the mix.
Select a container with a drainage hole or be prepared to drill holes for drainage if there are none.
Prepare the container by filling with potting soil up to 2” (5cm) from the rim of the planter. Remove the plant from its pot.
Make a small hole in the soil slightly larger than the root ball either by hand or using a trowel. Insert the plant into the hole and press soil firmly around the roots and just covering the root ball. When all the plants are potted, water thoroughly to settle the soil and give plants a good start. Place plant in a reliably sunny location.
Repot every 2 years in the same container or in a container slightly larger than the diameter of the roots.
Watering Instructions
Prefers moist but well-drained soil. Check the soil moisture with your finger. If the top 2-4” (5-10cm) of soil is dry, or plants are wilted, it is time to water.
Apply water at the soil level if possible to avoid wetting the foliage. Water the entire soil area until water runs out the base of the pot. This indicates that the soil is thoroughly wet.
Pruning Instructions
Most container plants can be pruned freely to maintain the desired size and shape. Keeping the foliage trimmed also keeps the plants looking neat and tidy, encourages the plant to develop more side-shoots and flowers, and reduces the demand for the plant to develop a larger root system. This is important since the roots are in a confined space.
Fertilizing Instuctions
Fertilizers are available in many forms: granulated, slow-release, liquid feeds, organic or synthetic. Determine which application method is best for the situation and select a product with a nutritional balance designed for foliage plants.
Too much fertilizer can damage plants so it’s important to follow the package directions to determine how much, and how often, to feed plants.
Slow-release fertilizers are an especially good, care-free choice for container plants. A single application can often provide plants with the proper level of nutrition all season long.
