What is an Olive Tree?

In the south of Europe, olives are grown primarily for their fruits and in their natural environment. They grow in olive groves, where they can reach a height of about 32 feet. Olives are one of the longest-lived trees, living for several hundred years in some cases.

Its curved trunk thickens in the lower part, and the canopy is quite broad. The bark of the tree is greenish-gray or ashy-gray. The leaves are small, leathery, silver-gray on the underside, and matte on the top. The blooming olive is full of yellowish-white flowers with a very intense scent.

The plant’s fruits are olives that can be green, black, or dark purple, fleshy, and contain oil rich in unsaturated fatty acids.

The 6 Tips & Tricks on How to Grow an Olive Tree Indoors

1. Variety

Olive trees can be bought in your local nursery or ordered online. To grow olives at home, you must first find the appropriate variety for planting indoors. You can find ready seedlings or small trees in most stores with garden material. Prices depend on the size of the tree, but most seedlings are not too expensive. It is advisable to buy a dwarf crop, though.

2. Pot

It is best to plant olive trees in pots so you can change their location when needed. The pot should be large to start with. The pot’s dimensions should be at least 23.6 inches deep and wide. It is necessary to drill a few extra-large holes in the bottom of the container for proper drainage.

3. Soil

An essential principle of olive growing is the creation of conditions close to the natural conditions from which this plant originated. The soil should be light, porous, and slightly sandy. It is best to choose a potting mix with excellent drainage characteristics, like cactus potting soil, perlite, or gravel.

4. Temperature and lighting

From mid-May, olive trees can be successfully moved and placed in a sunny place on the terrace or garden. The minimum temperature at which the olive tree thrives is about 35.6°F. The ideal temperature should be between 68°F and 75.2°F during this period. When the temperature drops below 32 °F, moving the olive tree to a well-lit place is best. Because autumn and winter are growing seasons, the room temperature should not be too high. Ideally, it should be between 39.2 and 59 °F.

This plant loves a lot of sun and heat. Therefore, it would be most appropriate to put it in the brightest area of your home. Tiny seedlings will grow comfortably on the southern window sills, but you will need to find a corner most illuminated by the sun’s rays for large ones. Moreover, it is desirable to light the plant from morning to evening. As an option, you can consider balconies and patios.

5. Humidity

Watering is mandatory every few days, depending on sunlight and temperature. The warmer it gets, the more water is needed. Ensure never to overwater this plant; the soil should be dry before watering. Do not sprinkle the leaves with water because they can turn brown after sun exposure. It is vital to water the olive tree regularly during the winter, but still very carefully.

6. Winter

Gardeners talk about the rapid adaptation of a plant cultivated outdoors to indoor cultivation. It is essential to provide the necessary temperature conditions for olives to keep your tree healthy. Characteristically, spring, summer, and early autumn are pleasant times for growing at room temperature, and in winter, the temperature must drop to 50°F–53.6°F. Therefore, it is best to move the olive tree to an insulated balcony in November. If you do not have adequate space, you can leave the pot in the same place, but be prepared for this to affect the amount of fruit.

Propagating an Olive Tree From Cuttings

Propagation by cuttings is done by splitting a few summer branches from the mother tree. The ends are sprayed with a growth stimulant, and you place the stem into a 4-inch deep hole. You will need a pot more than 7–8 inches deep. It is best to create a greenhouse effect, and for this purpose, the seedlings are covered with a transparent jar.

Olive tree rooting usually occurs in 4–5 weeks when young leaves begin to appear. The final formation of the root system occurs after 3–4 months, after which it is best to transfer the plant into a large container and keep it in a permanent place.

Tips and Tricks On How to Grow an Olive Tree Indoors

  • If your olive tree is placed in a room near the primary heating source, be sure to spray its canopy with water.
  • When buying a seedling, you should choose a specimen older than 2 years. The price will be higher than seedlings, but it is worth it since the plant will have an overgrown crown and a strong root system. This tree will more easily withstand habitat change.
  • Remember that olives are not eaten raw, directly from the tree. As a rule, they must sit in saltwater before use.
  • When forming the canopy, pay attention to the branches that compete with each other and, if possible, remove those that are weaker. For good fruit production, all shoots must receive light equally.
  • When you notice that the size of the plant and the pot do not match, you will need a new larger pot. The new pot should be larger by only a few inches in diameter and made of clay. This material allows the root to breathe. It is advisable to transplant olives every 2 years or so.
  • Any soil is suitable for an olive tree and a traditional potting soil mixture is best for many houseplants, including indoor olives. Place expanded clay or broken brick crumbs on the bottom of the flower pot for additional drainage.
