Watering Requirements

In order to thrive, you’ll need to water your Lemon-lime Philodendron regularly. These plants don’t need much water but should be given small amounts often. Wait until the top layer of soil feels completely dry before watering your plant. You can water less in the winter months.

Humidity Needs

Your plant will be able to tolerate dry conditions but does like to grow in humid areas. You can mist your plant’s leaves throughout the summer or put a water tray underneath your plant. This will help keep the leaves in good condition.


When growing Lemon lime philodendron, it’s best to use well-drained soil. You can also add a layer of gravel at the bottom and mix in some perlite or peat moss. This will help your plant avoid common problems such as root rot.


Philodendron lemon-lime plants prefer to grow in bright indirect sunlight. However, they are also able to tolerate partial shade. Don’t leave your plant in direct sunlight as this could cause sunburn, which will make the leaves droop and turn brown.


You can feed your plant with a highly diluted houseplant fertilizer in the spring and summer. Providing a light fertilizer throughout the growing season will help your plant stay healthy and increase its growth. During the winter, you can reduce fertilizer to once every two months. Don’t overfertilize your plant as the chemicals may burn the plant.


These plants grow long dangling vines which make them nice to grow on a windowsill or shelf. When the vines get so long that they touch the floor, you may want to give your plant a trim. In ideal conditions, these vines can grow to be up to 20 feet long. Dangling vines can be cut with a sharp, clean knife or pair of scissors.

You may also like to remove some of your plant’s leaves to stop the plant from spreading. You can easily pinch the leaves to remove them. Ensure you’ve left behind enough of the plant’s leaves so that it’s able to continue photosynthesizing and stay healthy.
