How to Grow an Avacado Tree Indoors

Overview

The seed of an avocado contains a fist-sized seed that will sprout quite easily. Because of this, a popular science activity among younger children is to get an avocado seed to sprout in a container of water. Avocado seeds can be planted in a container and will produce a tree that grows well indoors. A seed-grown tree will not mature quickly, and may not produce fruit for up to 15 years.

Step 1

Mix a potting soil that contains 1 part peat moss, 1 part sand and 1 part compost.

Step 2

Cut a square piece of window screening that is slightly larger than the drainage hole of your container.

Step 3

Place the screening over the drainage hole of the container and fill the container with the potting mix.

Step 4

Rinse the avocado pit to remove any fruit meat from the exterior of the pit. Scrub the surface with a scrubbing pad to remove the paper shell of the pit.

Step 5

Hollow out a depression in the center of the soil in the container. Place the large end of the egg-shaped pit into the depression and cover with soil so that the pit is halfway buried.

Step 6

Water the seed so that the soil is as damp as a wrung out sponge. The pit will begin to grow roots in a few weeks and the top of the pit will split open as the trunk of the tree emerges. Place the tree in a south-facing window where it will receive enough sunlight. Supplement the sunlight with plant grow lights.

Step 7

Check the container daily and water as the soil dries out. Use a liquid balanced fertilizer (10-10-10). Transplant the avocado into larger containers before the plant becomes root bound.
