Temperature and Humidity Levels

when it comes to heartleaf philodendron care, it flourishes well as a house plant indoors. The home’s temperature is ideal for this tropical plant.

The best growth for the sweetheart plant is at temperatures between 70°F-80ºF (24C°-27ºC) throughout the day and night above 55º F (13ºC). Your indoor plants do not enjoy cold water, drafts, or even heat found in the home in winter. Scandens and other heart-leaf philodendron can be planted in USDA hardiness zones 10-11

The Philodendron scandens love high humidity and will do well in your bathroom when receiving enough bright light. In addition, with higher humidity, it grows healthier roots with showy leaves. Still, your heartleaf philodendron can tolerate a lower humidity as well.

But it helps to keep an eye on brown leaf tips as it shows dry air and needs a bit more moist air. You can mist your plant or place it on a pebble tray with water to increase the moisture.

Repotting and Pruning

The heartleaf philodendron you need to repot every three years with a fresh potting medium and provide the root system with space to grow. If your plant is root-bound, it will grow slower.

Another important note is to prevent creating a drainage layer at the bottom as it is more detrimental to your plant. The reason is that the water moves down via gravity, but it stops at the layer and seeps into the small stones, which becomes problematic.

Another rare thing that can happen to your sweetheart plant indoors is flowering. This only occurs with a mature plant that is about 15 years old. The primary purpose of flowering is reproduction.

If it does bloom, you will see up to three buds opening up over the blooming period for a few days. Next, you will notice a spathe forming with a white spadix with a fertile male and female flower.

You can pinch back the stems to prevent leggy growth as it helps keep your plant looking great. Doing this helps trigger growing points in the leaf node leading to a bushy plant. The best time to do this is in the warmer months when actively growing.

Propagating Your House Plants

Propagating your sweetheart plant is pretty easy with rooting the stem cuttings.

  • You can cut up to four-inch cuttings from the stem tips at the beginning of spring or early summer. It helps if you leave up to three leaves attached, cutting below the leaf node.

  • Take a glass of tepid water and place your cutting in it, standing in indirect light until the roots develop.

  • Now, you can plant it in potting soil and keep it moist.
