How to look after an indoor olive tree
If you’re thinking about growing an olive tree indoors, make sure you place it in a spot where it can receive as much sunlight as possible.
Mitch Lowe, Horticulturist at Government House South Australia, says to "monitor the amount of light they get as they are a full sun tree. Rotate every month, so it can grow towards your light source evenly."
As well as needing plenty of sunshine, it's important to note that olive trees can grow quite large, so consider choosing a dwarf variety.
Olive trees need to be planted in a large container with plenty of holes for drainage. Filling the pot with gravel or similar filler at the bottom will help keep the soil well-drained.
Be careful though, as overwatering can kill your tree. Water until the soil is soaked, letting the topsoil (about 5 cm) dry out before watering again.
The bad news:
Olive trees aren't your typical indoor plant. As they require a lot of direct sunlight, they will eventually need to be moved outdoors. According to this website, you're looking at about eight or nine years with your indoor plant.
