-There are over 1,000 different varieties of lilacs and they come in many colors. The most popular is the purple, with pink and white coming in close seconds.
-As beautiful and fragrant as they are, lilacs bloom for only a few short weeks in the springtime. In order to prolong their magnificence, consider planting a variety of lilacs including early, mid, and late bloomers. Doing this should help ensure that you enjoy the fragrant blossoms for up to six weeks.
-Pruning is very important for lilac bushes as it gives them a more attractive shape and look but also has an effect on the health of the bush. They should be pruned each year but the timing is very important. Prune your bush immediately after the blooming is over for the season.
-Lilacs need very little care to grow but do not appreciate getting their roots wet for long periods of time. With this in mind, the most appropriate sites to plant lilac bushes are in slightly elevated areas, hillsides or on level ground where a good amount of drainage can take place.
Soil
-Clay is as fertile as any other kind of soil but has a tendency to become water- clogged. To improve drainage, add compost, gravel or sand to the clay.
-Drainage occurs too quickly when soil is light and sandy. To improve the condition of the soil, add compost, peat or farm manure.
-Mulching is a process of scattering vegetable material like straw, peat, or grass clippings over the surface of flower or vegetable beds. Mulching is a good gardener’s habit and yields many benefits for plants- it locks in moisture in the summertime; cuts down on weeds by smothering them and as it rots it adds nutrients to the soil.
