Philodendron Silver Sword also known as the Philodendron Hastatum is a popular houseplant known for its silver-blue hue that is unlike other houseplants.

As the Philodendron Hastatum matures, the leaves grow larger and morph into a sword shape, giving the plant its name Philodendron Silver Sword.

Philodendron Hastatum main care tips.

  1. Water. Philodendron Hastatum like to stay moist. Water this plant when the top inch or two of soil is dry and make sure to water thoroughly.

  4. Humidity. Philodendron Hastatum are tropical plants and love humidity at around 60% but can live in lower humidity conditions.

Philodendron Hastatum thrive with these care tips.


Philodendron Silver Sword thrive in bright indirect sunlight. A room with east, south, or west facing sun is great for this tropical houseplant.

You can also place this plant under plant grow lights. I use T5 Barrina plant grow lights for the majority of my plants. These lights run on a timer for 13 hours every day.

Sufficient lighting is so important for plant growth and can increase the chances of your plants even flowering in the home.


Water Philodendron Hastatum when the top inch or two of soil is dry. Make sure to water your plant thoroughly.

You’ll know if you’re watering correctly if you see water coming out through the bottom of the pot.

If you tend to be an underwaterer or overwaterer, use a moisture meter which will tell you when the soil is dry or moist. One of the most common reasons people kill their plants is because they water too much. Your plants need way less water than you think probably.


Philodendron Hastatum thrive in well-draining soil just like most houseplants.

An easy soil recipe is 2 parts coco coir, 2 parts perlite, and 1 part orchid bark.

If you don’t want to make your own potting mix, use premade soil like Fox Farm Ocean Forest. This blend contains high quality ingredients that contain everything you need to grow healthy houseplants in your home.

You can also grow this plant in a leca or lechuza pon substrate if you prefer a semi-hydroponic method of growing plants.


Philodendron Hastatum thrive in regular home temperatures of 70°F to 80°F. You can also grow this plant outside if you live in USDA hardiness zones of 9b-11.

This plant does not do well in colder temperatures outside under 60°F (15°C). It’s also important to place this plant in a spot that does NOT get drafts (keep away from windows, doors that lead to the outside, or vents).


Philodendron Silver Sword enjoy fertilizer during the active growing season. Fertilizer gives your plant the nutrients it needs to thrive in your home.

Fertilize your Philodendron Hastatum when the plant is actively growing. For me, that’s year round since I live in a place that doesn’t really get winter. Fertilize using a slow release granule fertilizer or an organic or synthetic fertilizer.

I use Dyna Gro to fertilize my plants. I get a spoonful of fertilizer and mix it into a gallon of water. Then I use this water to feed all of my houseplants.

If you are using a non-organic, synthetic fertilizer, it’s always recommended to dilute the recipe in half because of how strong the N-P-K ratios are. If you are using an organic fertilizer, you typically do not have to worry about diluting the recipe because the N-P-K ratio is so low.


Philodendron Hastatum are tropical houseplants and love higher than average household humidity. Humidity levels between 60%-80% are ideal but I’ve also found this plant can live in normal humidity conditions.

If your home is relatively dry (under 30% humidity), you may want to invest in a humidifier or put your plant under a pebble tray with water. I keep my house at about 40% humidity and my higher needs humidity plants are at about 60% humidity in a DIY Ikea greenhouse cabinet.

Best tips to raise the humidity in your home:

  • Put high humidity plants together in a group. When you group high humidity plants around each other, this creates a humid microclimate. The plants will continue to release moisture around each other through transpiration.
  • Place a pebble tray underneath your high humidity plants. I purchased small rocks at a hardware store and placed them on a planter tray. Place your planter on the tray. Put enough water in the tray until it hits the planter bottom and the water will evaporate around the plant.
  • Get a humidifier and run it daily near your houseplants.
  • Mist your plants. Some people say this doesn’t help, but I think it does so I continue to do it.
  • Place high-humidity plants in your bathroom. I place certain high humidity plants in my shower and they’re thriving.

I keep my Philodendron Hastatum in a greenhouse that I made. The plant seems to enjoy it.


Propagating a Philodendron Hastatum is easy. Make a cut underneath 2-3 nodes and place those nodes in water. In about one month you will see roots growing from the nodes.

Once the roots are about 2 inches in length, you can pot your Philodendron Hastatum or move the plant to whichever substrate you prefer.

Common pests

I haven’t had any pest pressures on my Philodendron Hastatum, but some of the most common pests for this houseplant include spider mites, mealybugs, scale, and aphids. These pests can hurt your plant which is why prevention is key.

To help prevent any pest infestations on your plant, here’s what to do.

  • Inspect your houseplant before bringing it home.
  • Treat your new houseplant with a natural or synthetic pesticide when you bring it home.
  • Quarantine your houseplant away from your other houseplants for at least two weeks.
  • Regularly check your plants for pests. This is also a great time to clean your plants.
  • Cut off dead leaves as dead matter can attract bugs.

If you find a plant that has pests on it, quarantine the plant away from your houseplants and clean the plant with an organic or nonorganic insecticide. I use Bonide Systemic on my plants as a preventative. Sprinkle the Bonide granules on top of your plants soil and the product will work its magic. This is a great method to get rid of fungus gnats.

I spray the plant and wipe down the leaves and stems twice a week for a month until I know the infestation is gone. Make sure to check all of your other plants as it is easy for pests to spread.

Bonide Systemic Granules are a great way to get rid of unwanted pests.
