Plant Care Guide for the Silver Sword Philodendron

While Silver Sword Philodendrons are one of the harder-to-find houseplants, they are not hard to take care of. They are able to adapt to many conditions indoors and won’t be high maintenance.

How To Water a Silver Sword Philodendron

Like many tropical plants, Silver Sword Philodendrons love moisture. They need to be watered regularly and not be allowed to completely dry out.

If you have a pot with good drainage water your plant until excess water starts to drain from the bottom of the pot.

You can also use a self-watering pot and allow the pot to sit in water until it soaks up enough water.

One of the great things about Silver Sword Philodendrons and water is that they are able to survive the occasional overwatering. So you do not have to be as rigorous with a watering schedule as some other plants.

Sword Philodendron Plant Light Requirements

Silver Sword Philodendrons like to have bright indirect light.

While these plants can live in low light or medium light conditions, it is not optimal for them. If you do put your plant in a low light area, it will not grow as well as it would in a brightly lit area.

They do not like direct sunlight. If they are in an area where the sun shines for a good part of the day through a window filter the light with something, such as a sheer curtain. Direct sunlight can cause the foliage to get burned and also fade.

What Soil to Use with Silver Sword Philodendron Plants

Silver Sword Philodendrons need well-draining soil that also stays moist and aerated.

A good peat-based soil with perlite (What Is Perlite?) to help with draining and aeration will work well for these plants.

Another popular option for a soil medium with plant lovers who have Silver Sword Philodendron is a mix of coco coir, earthworm castings, perlite, and orchid bark. This mixture resembles more of the base that these plants would grow on in the rainforest.

The Best Type of Pot for a  Silver Sword Philodendron

Pick a pot that has drainage. Avoid allowing your plant pot to hold on to excess water can lead to root rot which plants have a very hard time recovering from.

Since these are moisture-loving plants do not use Terracotta or unglazed clay pots. These types of pots dry out the soil fast.

Repotting a Silver Sword Philodendron

Silver Swords need to be repotted once you see the roots starting to grow out of the pot.

Find a pot that is a couple of inches bigger than the current pot. When you repot make sure to check the root ball for any signs of rot or disease. Remove any damage that you find. Give the plant new soil and put it in its new pot.

Silver Sword Philodendron Plant Propagation

Using stem cuttings is the best way to propagate a Silver Sword Philodendron. They are a very easy plant to propagate.

To get a cutting, take a clipping from a vine that has several leaves on it. You can then get multiple cuttings from this one stem by cutting between the leaves and leaving a note at the end of the leaf.

Place your cuttings in some water and within a couple of weeks, they should start to grow new roots.

Silver Sword Philodendron Toxicity and Pets

The ASPCA shows philodendrons are toxic to pets. 

All Philodendrons have calcium oxalate crystals. These crystals are toxic if they are ingested so keep this plant in a place that your pets can’t chew them.

If you do have trouble keeping your pets from munching on your plants you can make a citrus spray with lemon juice to spray on your plants. Bitter Apple spray is another option to use, many pets don’t like the taste or smell.

Fertilizing a Silver Sword Philodendron

Silver Sword Philodendrons should be fertilized during the spring and summer, which is their growing season. You do not want to fertilize the plant in the dormant seasons of fall and winter.

It is best to use a liquid fertilizer for houseplants and follow the directions on the bottle. Silver Swords can grow at a pretty fast rate so fertilizing during the growing season is essential for them to thrive.

Temperature Needs

Since these are tropical plants they do not tolerate cold temperatures well and prefer warmer temperatures. Do not let the temperature go below 55°F or above 90°F.

Optimum temperatures would be a range between 65°F and 85°F.

Humidity

Like many philodendrons, Silver Swords like high humidity.

Try to keep humidity above 50%, but the higher the better. In the rainforest, these are used to humidity being 85% or higher.

If you find the area where you keep your Silver Sword is getting too low in humidity you can help increase the humidity levels around the plant by grouping it with other plants.

You can also use a pebble tray with water that can increase the humidity around the plant as the water evaporates. This can also help capture run-off water from the plant pot.

Another option that people like to use with plants that like high humidity is to use a humidifier in the room where they keep their tropical plants.

Indoor greenhouse cabinets are becoming a popular thing to use for high humidity plants. By using these you can keep your plants in an area that can be temperature controlled and keep humidity levels in check easily.

Pruning Silver Sword Philodendron Plants

Silver Sword Philodendrons don’t require much for pruning.

Remove any damaged or dead leaves and if the vines are getting too long you can cut them back to a length that suits you best.

Common Problems With Silver Sword Philodendron Plants

Mealybugs and Aphids

While Silver Swords aren’t as susceptible to many houseplant pests, mealybugs and aphids can cause issues with them.

Mealybugs look like little white cotton-like fluffs that usually like to hang out on stems right at the node. But they can also be found on the undersides of leaves.

Aphids are also small and like the undersides of leaves and the new growth on the plant. They can be many colors: pale green, yellow, grey, black, red, or pink. You will find them clustered together most often. If the infestation is bad you might find dead ones that have fallen off the plant leaves and be around the outside of the pot.

For either of these pests use insecticidal soap for your best chance of getting rid of them.

Yellow Leaves

Yellow leaves on a Silver Sword Philodendron is usually a sign that the plant is being overwatered.

Allow more time between your waterings and allow your plant to have more time for the soil to dry some.

Curling Leaves

If you have just repotted your Silver Sword curling leaves could just be a normal reaction to the shock that repotting can cause.

If you have not repotted your plant recently or put it in a new location where there was a significant temperature change check the drainage of your pot. Make sure that the pot is allowing drainage of excess water.
