olive tree bonsai

I live in Northern Italy in areas where it is very cold in winter, can I keep it?

The olive tree is a Mediterranean plant that loves the heat and, in the case of bonsai, it can withstand up to 2-3 degrees below zero for a few days. So if you live in areas where the temperature drops well below freezing, and especially for long periods, be sure to put it indoors near a window or shelter it in a greenhouse.

Do I keep the Olive bonsai indoors or out in the sun?

The olive tree is a heliophilous plant (lover of the sun), it must therefore be exposed to full sun, even for the whole year; it is preferable to place it in partial shade during the height of summer if you live in very hot areas of Southern Italy. It can also be kept indoors in a very bright and very airy place, away from heat sources, logically it will never have the vigor of an olive tree kept outside!

How should I prune the olive tree?

The most drastic pruning can be done in winter, when the plant is at rest and no sap is coming out; you can make the cuts with the oblique cutters, taking care to close the larger cuts with mastic for hardwoods . Around June you can thin out the leaves born in the year with a scissors for twigs , in order to better penetrate the light inside the plant and to develop new branches that will thicken the bonsai stages more and more. Any suckers and suckers that arise on the trunk (often at the base) and which do not serve the formation of the plant, eliminate them as soon as possible.

How and how often do you repot?

The olive tree is repotted every 2-3 years, in the phase from February to April (before and just after the vegetative restart) by pruning the roots with a root shear to the extent of about one third. The olive tree tolerates even more drastic clods well, but be sure to dump much of the existing vegetation. The perfect mix of soil does not exist and must be calibrated mainly based on the climate in which you live, but a suitable soil for an olive tree bonsai is made up of about 50% pumice , mixed with good universal soil in the measure of 40%, and 10% river sand . You can increase the pumice and decrease the soil if you live in cooler areas and vice versa if you live in very hot areas.

How often should I water it?

Always remember that there is no rule for watering a bonsai (2 times a day, 3 times in 2 days, etc ...) This plant grows in areas with a dry climate, but also likes abundant watering; it is advisable to water it abundantly, letting the soil dry out between one watering and the next . You can water your olive tree bonsai with a handy bonsai watering can .

How can I fertilize the olive tree?

Fertilize with Hanagokoro or Biogold organic fertilizer towards the vegetative restart (March), another fertilization towards May and another in autumn. You can integrate the fertilization with Sinergon , a liquid fertilizer to be used 2-3 times a month (rich in microelements and amino acids) throughout the vegetative period, interrupting in the hottest period of summer.

Can I tie it with bonsai wire?

Of course, the olive tree is one of the most popular species as bonsai and also lends itself to fairly drastic binding. Use aluminum wire to tie the olive tree and preferably do it during the period of vegetative rest, so as not to damage the bark which is very delicate, in the period in which a lot of sap flows.
