The Philodendron Hastatum is a large philodendron with greeny-grey-silver leaves These are very decorative houseplants, it is stunning and will stand out in and demand attention as the leaves do not look natural they are alien-like in their gray coloring. Originally from Brazilian rainforests, it needs to be treated as a tropical plant, and semi-epiphytic, we’ll run down how to care for it…
Bright indirect sunlight is ideal for a hastatum. I like to keep my philodendrons in a south facing room, but back from or to the side of the window so they sun does not hit them, but they get loads of light.
How Often to Water A Philodendron Hastatum
Check your philodendron hastatum once a week and water them in the top half of soil is dry. They really do not want to be water logged in any way, they do not always grow in soil in the wild, but can grow in bark pieces too, so water logged soil can lead to root rot quickly. Do not let it sit in water.
Use a balanced feed once a month in the spring and summer growing months. Philodendrons really benefit from feeding and tend to grow much more when fed. I like to feed mine a much more diluted fertilizer the first time I feed them in the year to ensure I don’t burn them, and then add a bit more each time, and I stop adding when I see increased growth..
A well-draining, rich potting compost will suit a hastatum well. You should add some perlite too to aid drainage, as the plants must not sit in wet soil for too long.
When To Repot A Philodendron Hastatum
Repot your philodendron hastatum when the roots start to grow through the bottom of its pot. They can grow quickly sometimes.
Philodendrons like the philodendron hastatum like 50% humidity which is the higher end of household humidity (most households are 30-50%). Give them a misting two or thee times a week.
Normal household temperatures of 18°C to 25°C (64-77°F) will be ideal for these silver sword philodendrons.
How To Propagate A Philodendron Hastatum Silver Sword
Sphagnum moss is your friend when it comes to propagation. Take a node cutting and bury the bottom node (strip it naked of leaves) it in a clear cup filled with moist sphagnum moss. Then put it in a warm place with bright indirect sunlight and wait for it to root which can take up to 2 months. Keep it moist by spraying it a few times a week. You should see the root growth, then the plant should start putting out new foliage at least by month 3.

FAQs and Common Problems
Philodendron Hastatum Yellow Leaves
Yellow leaves due to waterlogging and root rot are an issue, makes sure you do not overwater these. When watering, I do not flush my philodendrons with loads of water, I give them just enough that only a few drips come out the bottom. And certainly they should not sit in water after watering, tip out the excess water.
Also keep an eye out for plant pests on their leaves, do not let an infestation take hold.
