Normally growing to a height of 40 to 80 feet, avocado trees raised as houseplants can be dwarfed to three feet or less depending on the size of the container it grows in. With alternating elliptical leaves, avocado plants have an exotic look and can easily be grown from pit.
- Cut a ripe avocado in half and remove the pit. Wash the pit thoroughly to remove any avocado flesh.
- Using toothpicks, pierce the sides of the pit to suspend it over a glass of water, broad side down. One inch should be fully submerged in water. Place the glass in a warm spot out of direct sunlight. Top up the water every couple days and replace it with clean water when it looks murky.
- It can take two to eight weeks for the pit to crack, a taproot to form, and a stem to emerge from the top. When the avocado shoot is about six inches, cut it back to three inches to encourage more shoots to grow.
- Once the stem is six inches again, transfer the pit to a rich humus soil in a 10” planter, leaving the top part of the pit exposed. Set it in a sunny spot.
Oranges, lemons, limes, grapefruit, tangerines, and kumquats are all good candidates for indoor planting. Exhibiting dark, glossy foliage, citrus plants may bloom sweet smelling flowers in the spring.
- Soak citrus seeds in warm water for 24 hours before planting in a sandy loam soil, a half inch deep, pointy ends of the seeds facing up. Water well and place the pot in a warm, dark location.
- To speed up germination, cover the pot with a plastic baggie to create a humidity tent.
- The first sprouts should pop up in two to six weeks. Remove the tenting and place in a spot that receives five to six hours of sunlight.
- As an ornamental, citrus trees should be pruned regularly to maintain a smaller stature.
