Start Avocado Seeds Indoors Anytime of Year
To start sprouting an avocado seed indoors in any season of the year, you only need a few items:
- A fresh avocado seed
- 3 toothpicks
- A glass or jar slightly larger than the avocado seed
Avocados seeds do best when they start growing indoors, any time of the year, by u suspending the seed in water in a glass using toothpicks.
Caring for Avocado Seeds
As long as the seed stays between 60ºF (15.5ºC) and 80ºF (26.6ºC) and receives indirect sunlight, or light from a grow lamp, for about eight hours each day, the seed will begin growing roots within six to eight weeks, regardless of the time of year it is started.
It is important to replenish the water in the glass as it evaporates. The avocado will not grow unless the bottom of the seed stays submerged in water the entire time it is sprouting and until it is transplanted into soil in the garden or a gardening pot.
As the avocado seed sprouts in the glass of water, roots will develop underwater in two to eight weeks’ time. After the roots start growing, a shoot will appear at the top of the seed. When the shoot has grown to about 8 inches high, the avocado is ready for transplanting into soil in a pot or outdoors.
Transplanting Avocado Tree Seedlings
Avocado trees can also be grown indoors indefinitely in a large gardening pot, as long as they receive enough light, but an avocado tree growing indoors will not receive enough light for producing fruit.
The best time to plant a growing avocado seed into the garden is between March and June when the temperature is warm but not yet hot. Young avocado trees cannot take up enough water from the soil if the outdoor temperature is too hot when they are first transplanted.
Whether you transplant the avocado seedling outdoors or grow it indoors in a pot, water it thoroughly at least once per week and more often if conditions are dry and hot.
Avocado trees grown outdoors take up to ten years to produce fruit. When grown from a seed, an avocado tree probably will not produce fruit of the same type as the plant which produced the seed.
