Growing an avocado tree is a time-honored tradition for many enthusiasts
around the world, but it does not have to be limited to an outdoor
garden.
It is possible to successfully grow an avocado tree indoors that is capable of producing fruit. Here are some tips and tricks to ensure an abundant harvest.
Location
When growing an avocado tree indoors, it is best to choose a south, east, or west facing windowsill to ensure adequate light.
If direct sunlight is not available, a sunny corner, countertop, or even a table planted with a sunny lamp can also provide more than enough illumination.
Exposure to at least eight hours of bright light is essential, as avocados are a tropical fruit.
Soil
When planting an avocado tree, it is important to use soil that drains well.
A commercial potting mix that is specifically designed for indoor plants is usually the best option. Alternatively, a mixture of compost and perlite can also be used.
A third option is to build a potting soil from scratch using equal parts compost, vermiculite, and peat moss.
Regardless of the soil choice, it should not be more than four inches deep in the pot, to prevent the roots from becoming waterlogged.
Pot Size
When selecting the ideal pot size for an avocado tree, start with a 10” tall pot.
It should also have drainage holes, as these help to prevent root rot.
As the tree grows, the pot will need to be replaced frequently and transplanted into containers of increasing sizes.
The ideal pot size is ultimately determined by the size of the tree, which can range from two to three feet tall.
Watering
When it comes to watering, avocados benefit from a consistent schedule, and should be given enough water to keep the soil moist, but not saturated.
The number of times it needs to be watered depends on a number of factors, including the size of the pot, the season, and the amount of light it is getting.
A good rule of thumb is to water it every other day, or when the top inch of soil is dry.
Fertilizing
Avocado trees will benefit from regular fertilizing to maintain optimal health and promote fruit growth.
Organic fertilizers are the preferred option, as synthetic fertilizers can damage the roots and harm the tree.
Compost tea or fish emulsion can be applied once every two weeks during the growing season.
It’s important to stop fertilizing several months prior to harvesting, as too much fertilizer can affect the flavor and ripening of the fruit.
Temperature
Avocado trees thrive in temperatures between 65°F and 85°F.
When the temperature drops outside, a space heater or an extra layer of insulation will help to maintain the temperature indoors.
It’s important to ensure that the temperature does not dip below 65°F for any extended period of time, as this can stunt the plant’s growth and delay the production of fruit.
Pruning
Pruning is an important part of indoor avocado tree maintenance.
Avocado trees can get a bit leggy if they are not pruned regularly.
The best time to prune them is during the winter, when the tree is dormant.
Removing dead branches and excess foliage will help to promote a healthy and productive plant.
Pollination
Avocados are not self-pollinating, so hand pollination is necessary if you want to produce fruit indoors.
Using a small paintbrush to transfer pollen from the tree’s stamen to the stigma of the flower will help to ensure proper pollination.
It’s also important to note that avocados require a certain amount of chill hours, or time spent in cool temperatures, in order to produce fruit.
If the temperatures were too high, it’s possible that the flowers dropped off before they were pollinated.
Harvesting
Avocado trees typically begin producing fruit two to four years after planting.
When the fruit is ripe, it should easily pull away from the stem.
If it is a bit stubborn, it can be gently twisted and then released.
For best flavor and texture, try to pick the fruit at the peak of ripeness.
Avocado Pests
Avocado trees are vulnerable to a range of pests, including caterpillars, spiders, mites, and whiteflies.
The best way to detect the presence of pests is to keep an eye out for any discolored leaves or webbing.
If any pests are spotted, it’s best to take immediate action using a pesticide.
It’s also a good idea to apply a preventative insecticide at least once a year.
Pest Control
Insects aren’t the only problem when it comes to caring for avocados.
Disease is also a real concern, as it can quickly spread and damage an entire crop.
The first step in preventing disease is to make sure that the soil is never too wet and that the tree is getting adequate airflow.
Additionally, it’s important to inspect the tree regularly for any signs of disease, such as discolored leaves or a sooty mold.
If any signs of disease are spotted, treatment with a fungicide should be done immediately.
Conclusion
Although growing an avocado tree indoors can be challenging, it is certainly possible with the right techniques and a bit of care.
It is important to remember to provide sufficient light, water, and fertilizer, as well as inspect the tree regularly for any signs of pests or disease.
By following these tips and tricks, you can soon be enjoying the delicious fruits of your labor.
