A small, low and picturesque spreading plant growing to a height of 4 feet. The branches are typically horizontal giving it a layered appearance. Leaves are tiny, bright and light green, about 1/4 inch long. New foliar growth is bronze-colored and ages to light green.
Black Olive Bonsais should be well-watered and never dry. Close attention must be paid to watering because Bonsai trees are grown in small pots and therefore dry out much more quickly than plants grown in the ground or in larger pots. To water the Black Olive Bonsai, place the pot in a sink filled with two inches of water. Let the water seep into the pot through the drainage holes. You may also mist your Black Olive Bonsai once each week to keep leaves hydrated.
The tree needs full summer sun. If grown indoors, place the tree outside during the summer months. Keep the tree cooler in winter, but avoid freezing conditions.
Feed every other week during spring and summer. Bonsai fertilizer is best, yet regular plant food may be used — but only at half strength. No fertilization is necessary in the three months following re-potting.
The trees grow best in zones 10B to 11. Ideally, the Black Olive tree should be kept in temperatures under 64 degrees during winter, but they should never be exposed to temperatures below 40 degrees.
Re-pot the tree after two or three years, and always in the spring. The ball of the roots should be trimmed by about one third. Use soil that allows for free drainage.
