SOIL & WATER

A Butterfly bush can grow in clay soil. You do not need to amend the soil. Plant it in natural soil. Do not add any topsoil or compost to it.

Their roots are sensitive to rotting. Therefore, do not let your bush sit in water. It should be planted in well-drained soil. While butterfly bush is fairly drought tolerant, it will need watering during the summer.

When planting a butterfly bush make a shallow hole. You want to plant it high. Do not plant it even on the ground. Let it sit higher. Why? Planting it higher than ground level with help the water to drain away from the plant rather than settle around it.

fertilizing

When do you fertilize your butterfly bush? You do not!

Avoid fertilizing butterfly bush; too much fertility promotes leaf growth over flower production.

pruning

Butterfly bushes must be pruned every spring to control the height and to promote growth on new wood. Pruning in the spring, after the new growth emerges works best. Never cut your butterfly bush back in the autumn. Yes, it can look spent. However, in cold climates it could kill your plant. Pruning it in the fall can leave your bush susceptible to damage over the winter.

You should not prune until you see green buds on the stems. The blooms will grow on new wood. You can cut them back to the ground each spring. With Titanium Bypass Pruning Shears, you will make your cuts just above the big, new green leaf buds. It can take several weeks into spring for new growth to show up. Do not prune before you see the new growth. You do not want to cut them back too early.

Always prune out the dead stems by cutting them close to the ground. It is important to prune them severely to stimulate an abundance of growth. This will help your bush to produce beautiful blooms.
