Dwarf Korean Lilac Care & Growing Guide

1. Light requirements

The Dwarf Korean Lilac needs at least 6 hours of direct sunlight to stay healthy and strong. If it receives less than the 6 hours of light it requires, it will not have the energy to bloom. But if the sun is too intense, like in the summer during a heatwave, the flowers may wilt up and fall off. 

2. Water

If you have young Korean lilac plants, you need to keep the soil moist. Do not let the lilac dry out until the roots have settled themselves into the soil, which takes at least six months or more. After that, you must water the lilac once a week in temperate weather, but if it gets hotter, then you have to water it every other day to every day. 

3. Climate

Korean Lilacs do best in chilly northern climates, but not in snow or sleet. It can grow in places that have humidity or warm climates. But the more humid the weather is, the less it must be watered. 

4. Soil

The soil that the Korean lilac roots into must be able to drain quickly, and it can’t have high acidity. The soil must be close to 7.0 basic soil, the closer to neutral, the better. If you can add humus to the soil, that would improve soil conditions even more.  

5. Temperature

Cold temperatures are an everyday companion to the Korean lilac. It can survive in temperatures of around -30 degrees, but it won’t have any flowers on it.

7. Repotting

Korean Lilac bushes are not meant to be kept inside a home. They are outside plants since they take up so much room. But if you have a lilac bush you want to transfer over another area, then you must dig up a large area of soil.
