Lilac (Syringa vulgaris ) is one of the most rewarding spring / early summer flowering shrubs. It rewards us with the most delicate fragrance and beautiful flowers. Even when not in flower, the lilac makes a nice attractive green leaved shrub, that can form part of a hedge or shelter the garden.
Tips for Growing Lilacs
- Lilacs do not like waterlogged soil. It is important to plant in a relatively free draining soil.
- They can tolerate hot sun and heat (and can provide a nice dappled shade for the rest of the garden.
- In long periods of draught, it may be necessary to water. But, make sure the water gets deep down.
- Lilacs are not heavy feeders. In good soil, a general purpose fertilizer once a year, will be adequate. Be wary of too much nitrogen as this can lead to green growth at the expense of blooms.
- Lilacs send suckers from the base. These are vigorous growers and can be separated from the main bush to create new plants. A cheap and easy way to propagate.
Pests and Diseases
- Lilacs remain relative pest free. I have never had any aphids with my lilacs.
- Lilacs can be subject to powdery mildew, especially when hot and humid. The best treatment for powdery mildew is removing affected leaves and burning, and treating with suitable fungicide.
