How To Care for Philodendron Selloum

Philodendron selloum is a robust plant that is relatively easy to care for.

With proper care, it will thrive indoors and provide years of enjoyment.

Here is what you need to know about Philodendron selloum care:

Sun Exposure & Light Requirements

Philodendron selloum is a tropical plant that thrives in warm, humid conditions.

It prefers bright indirect light but can tolerate some direct sunlight. However, too much direct sun can scorch the leaves.

It will tolerate some light shade, but too much shade will result in leggy growth.

Philodendron Hope needs at least 4 hours of bright light daily to maintain its lush, green foliage.

When growing philodendron selloum indoors, place the plant near an east- or west-facing window.

This will provide the bright indirect light that the plant needs.

If you don’t have a window that gets enough light, you can supplement with grow lights.

When growing philodendron selloum outdoors, place the plant in a spot with partial sun.

The morning sun is best as it won’t be as harsh as the afternoon sun.

If you live in a hot climate, it’s best to provide some afternoon shade to prevent the leaves from getting scorched.

Watering Requirements

The Philodendron selloum is a tropical plant that does best with consistent moisture.

It’s essential to keep the soil evenly moist but not soggy.

Allow the top inch of soil to dry out in between watering.

The plant should be watered about once or twice a week during the growing season.

During the winter, cut back on watering slightly, allowing the top inch or so of soil to dry out completely between watering.

When it comes to watering, give your Philodendron selloum a good soaking and then allow the excess water to drain away.

Be sure to empty any water collected in the saucer or tray beneath the pot.

When watering, be sure to use lukewarm water.

Cold water can shock the plant and cause leaf drop.

It’s also a good idea to use a water filter if your tap water is high in minerals, as this can build up over time and cause problems for the plant.

Soil Requirements

When growing Philodendron selloum, it’s essential to use a loose, well-draining potting soil mix.

This plant doesn’t like to sit in wet soil, which can lead to root rot problems.

A good potting mix for Philodendron selloum would be a mixture of potting soil, peat moss, and perlite.

This mix will provide the plant with the necessary drainage while retaining some moisture.

You can also add some compost to the mix to help provide extra nutrients.

A succulent or cactus mix can also be used, but add extra perlite or sand to the mix to ensure good drainage.

Temperature and Humidity

The Philodendron Selloum prefers warm weather and high humidity.

The ideal temperature range for this plant is between 60-85 degrees Fahrenheit.

If the temperature drops below 60 degrees Fahrenheit, the Philodendron leaves will start to turn yellow and brown.

If the temperature rises above 85 degrees Fahrenheit, the leaves will wilt.

It’s best to keep this plant away from drafts and windows where it can be exposed to cold air.

The ideal humidity level for this plant is between 60-80%. If the humidity level drops below 60%, the plant leaves will start to turn brown and crispy.

To increase the humidity level around your Philodendron Selloum, you can do one or all of the following:

  • Group your plants together: This will create a microclimate around your plants that will be more humid than the surrounding area.
  • Use a pebble tray: Place a layer of gravel or rocks in a shallow tray and add water to it. Place your Philodendron Selloum on top of the pebble tray. The water will evaporate and increase the humidity level around your plant.
  • Use a humidifier: This is the most effective way to increase the humidity level around your Philodendron Hope.

Fertilizing

Philodendron selloum, like most plants, will benefit from regular fertilization.

Use a balanced fertilizer such as 20-20-20 or 10-10-10 at half strength monthly during the growing season (spring and summer).

A liquid fertilizer is best, but a granular fertilizer can be used if it is watered well.

Be careful not to over-fertilize as this can burn the roots.

It’s best to apply fertilizer to moist soil to avoid root burn. Never fertilize a dry plant.

Hope Philodendron will also benefit from occasional applications of compost or manure.

Apply a thin layer of compost around the base of the plant in spring and summer.

You can also add a handful of manure to the planting hole when you transplant Philodendron selloum.

Avoid fertilizing in the winter when the plant is dormant, as this can damage the roots.

Potting and Repotting

Philodendron selloum are slow growers and usually only need to be repotted every 2-3 years.

The benefits of repotting are twofold.

Firstly, it allows you to give your plant some fresh soil which will contain more nutrients than the old soil.

Secondly, it allows you to check the roots for any problems and gives the plant a little extra room to grow.

The best time to repot your plant is in the spring before new growth begins.

When repotting, choose a pot that is slightly larger than the current one.

This will help to prevent root rot and keep your plant healthy.

It’s also best to use a glazed pot with drainage holes to help prevent waterlogging.

To repot, gently remove the plant from its pot and loosen any compacted roots.

Place the plant in the new pot and fill in around it with fresh soil.

Water well and allow the soil to drain before placing the plant back in its spot.

Pruning

Philodendron selloum can be pruned at any time of year, but the best time is in late spring or early summer, just before new growth begins.

Pruning will encourage your plant to branch out and become bushier.

It’s best to use sharp, clean pruning shears to avoid damaging the plant.

To prune, cut back any leggy or overgrown stems to the desired length.

Cut just above a leaf node (the point where a leaf is attached to the stem) to encourage new growth.

You can also remove any damaged or dead leaves.

This will help to keep your plant healthy and looking its best.

Pests

Pests can become a problem with any type of plant, and Philodendron selloum is no exception.

Several types of pests are known to attack this plant, including mealybugs, aphids, spider mites, and scale insects.

Mealybugs are small, white, fuzzy insects that feed on plant sap. They can cause leaf yellowing and stunted growth.

Aphids are small, pear-shaped insects that feed by sucking plant sap. They can cause Philodendron leaf curling, stunted growth, and distortion of new leaves.

Spider mites are tiny spider-like creatures that feed on plant sap.

They can cause mottling and discoloration of leaves and webbing on the undersides of leaves.

Scale insects are small, hard-bodied insects that feed on plant sap.

They can cause yellowing and growth stunting, as well as a sticky residue on leaves.

If you notice any of these pests on your Hope Philodendron plant, it is vital to take action immediately.

There are several ways to control pests, including using insecticidal soap, neem oil, or horticultural oil.

Using a cotton swab or a soft brush, you can also remove pests by hand.

Introducing beneficial insects, such as ladybugs, into your garden can also help control pests.

Diseases

Several diseases can affect Philodendron selloum, including root rot, leaf spot, and stem rot.

Philodendron root rot is caused by a fungus attacking the plant’s roots.

It’s usually the result of overwatering and causes the roots to turn black and mushy, leading to the death of the plant.

Leaf spot is caused by a fungus that attacks the plant leaves. Fungus thrives in moist, humid conditions, so keeping the leaves dry is essential.

It causes small, dark brown spots to form on the Philodendron leaves, which can eventually lead to leaf drop and plant death.

Stem rot is caused by a fungus that attacks the plant’s stems.

It can result from overwatering or damage to the stem and causes the stem to turn black and mushy.

Once stem rot has set in, it’s complicated to save the plant.

The best way to prevent diseases is to practice good plant hygiene, such as disinfecting your tools and pots and watering only when the soil is dry.

If you notice any signs of disease on your Philodendron selloum, it’s vital to take action immediately.

The best way to treat diseases is to cut away any affected parts of the plant and dispose of them in the trash.

You can also treat diseases with a fungicide, but it’s essential to follow the directions on the label carefully.
