Water Requirements for Lilacs


Lilacs generally don't need a lot of water, but in hotter climates in the confines of a bonsai pot they may need more than usual. For proper watering techniques for bonsai read this article on watering. The soil should feel on the moist side, but not wet.


Sunlight for Lilacs


Lilacs need to be kept outdoors where they can receive 6 hours of direct sun per day. That being said, in warmer locations (USDA zones 9-10) you may need to find a location where it will receive less sun and more shade so that the tree does not overheat.

Lilac Soil Preference


Lilacs in bonsai pots will prefer a loose well draining bonsai soil. They prefer the soil to be tipped just slightly acidic to neutral in the 6.5 to 7 pH range. This fits the description of many bonsai soil mixes.


Pruning and Fertilizing


Lilacs don't require much fertilizer. If the growth appears stunted you can apply a half strength dosing of a slow release 5-10-10 fertilizer in October. Lilacs should be pruned after they bloom in the spring. If lilacs are pruned in the summer, fall, or winter months the tree may not bloom the following year. Flowers should be removed once they begin to shrivel. Also, if the lilac is fertilized with too much nitrogen it may not bloom and grow more leaves instead.


Lilac Pests and Diseases


Common pests of lilacs include powedery mildew and scale. Powdery mildew can be treated with a potassium bicarbonate spray available from most home improvement stores.
