Understanding Lilac Growth Habits
Lilacs are deciduous shrubs that bloom on old wood. This means that the flower buds for next year’s blooms are formed on the current season‘s growth. Therefore, pruning lilacs involves removing old or unwanted branches to encourage new growth and abundant flowering.
Best Time to Prune Lilacs
The ideal time to prune lilacs is immediately after they have finished blooming, typically in late spring or early summer. This allows the plant to direct its energy towards producing new growth and flower buds for the following season.
Pruning Techniques for Lilacs
1. Removal of Dead or Diseased Branches:
Start by removing any dead, diseased, or damaged branches. These branches are not only unsightly but can also spread disease to the rest of the plant.
2. Thinning the Center:
To improve air circulation and prevent overcrowding, thin out the center of the lilac shrub. Remove suckers, weak branches, and any branches that cross or rub against each other.
3. Pruning for Height and Shape:
Determine the desired height and shape of your lilac shrub and prune accordingly. Cut back long branches to reduce the size and shape the plant.
4. Rejuvenation Pruning:
For older or overgrown lilac shrubs, rejuvenation pruning may be necessary. This involves cutting back the entire shrub to within 12-18 inches of the ground. This drastic measure will stimulate new growth and rejuvenate the plant.
5. Removing Spent Blooms:
After flowering, remove the spent blooms by cutting them back to the first set of healthy leaves. This will prevent the plant from putting energy into seed production and encourage new growth.
Tips for Successful Lilac Pruning
- Use sharp, clean pruning shears to avoid damaging the plant.
- Make clean cuts at a 45-degree angle.
- Avoid pruning too severely, as this can reduce flowering.
- Remove suckers from the base of the plant to prevent overcrowding.
- Fertilize the lilac shrub after pruning to promote healthy growth.
