To start to grow a coconut plant, begin with a fresh coconut that still has the husk on it. When you shake it, it still should sound like it has water in it. Soak it in water for 2-3 days.
After the coconut has been soaked, place it in a container filled with well-draining potting soil. It is best to mix in a little sand or vermiculite to make sure the soil you will be growing coconut trees in drains well. The container needs to be around 12 inches deep to allow for the roots to grow properly. Plant the coconut point side down and leave a 1/3 of the coconut above the soil.
After planting the coconut, move the container to a well lit, warm spot. The warmer the better. Coconuts do best in spots that are 70 degrees F. (21 C.) or warmer.
The trick to growing a coconut palm tree is to keep the coconut well watered during germination without letting it sit in overly wet soil. So, water the coconut frequently but make sure the container drains very well.
You should see the seedling appear in 3-6 months.
If you want to plant a coconut that has already sprouted, go ahead and plant it in well-draining soil so that the bottom 2/3 of the coconut is in the soil. Place in a warm area and water frequently.
Care of a Coconut Tree
Once your coconut tree has started growing, you need to do a few things to help keep it healthy.
First, water the coconut tree frequently. As long as the soil drains well, you really can’t water them too often. If you decide to repot your coconut tree, remember to add sand or vermiculite to the new soil to keep the water draining well.
Second, growing coconut palms are heavy feeders. They will need regular and complete fertilizer. Look for a fertilizer that provides both the basic nutrients plus trace nutrients like boron, manganese and magnesium.
Third, coconut palms are very cold sensitive. If you live in an area that gets cold, your coconut plant will need to come inside for the winter. Provide supplemental light and keep it away from drafts. In the summer, grow it outdoors and make sure you place it in a very sunny and warm spot.
Coconut trees that are grown in containers tend to be short lived. They may only live for 5-6 years. But, even though they are short lived, growing coconut trees can be a fun project.
