Post Planting Tips

Watering: Newly planted lilacs should be watered at least once a week if there is no rain. Once established your lilac will be able to cope with dry spells, especially you applied 3-4 inches of bark mulch. Too much water is just as bad as too little so a great way to check your lilac is to pull back some of the bark mulch and with a garden trowel dig into the soil 2-3" to see with the soil is moist or dry. A slow trickle from a garden hose is still the best method to be sure your  lilac is getting an adequate amount  of water.

Fertilizing: The best time to feed you lilac is in early spring a few weeks before the leaves come out. At the nursery we use an 8-20-16 Lilac Food that is enriched with lime and seaweed. The best method for applying a granular fertilizer is to apply it under the bark mulch out by the drip line of the lilac. This helps to make sure the lilac food is going down to the roots and not dissipating into the air as it breaks down. Lilacs like a soil that has a near neutral pH they don't like a sweet soil but they do like a soil that is rich in organic matter and that is why the lime is needed to help raise the pH. You can also use wood ash in place of lime but you need twice as much. Lime and wood ash are not fertilizers they are only used to help keep the pH near neutral. Fertilize your lilac again right after blooming season ends or by the 4th of July. Never fertilize your lilac in the fall. 

Pruning: Please dare to prune your lilac it's the most important step needed to insure good quality flower production. The best time to prune an over grown  lilac is in the winter months however when you prune in the winter you a sacrificing flower buds so if you can't bear to do that always prune right after blooming season ends and I mean right after. You can cut older trunks down to 12" use a chain saw if necessary when trying to rejuvenate an old lilac stand. Removing 1/3 of the older trunks per year is a tried and true method for turning an old lilac that looks like a tree back to looking like a bush. Dead heading or the removal of spent blooms is strictly done to make your lilac not look so unsightly it will not help in next years flower production that is an old wives tale.

Facts about lilac color

1. Cool damp weather at blooming time can make lilacs look darker and richer in color.

2. Hot, dry sunny weather at blooming time can cause blooms to fade to lighter shades faster as the pigment gets bleached out quicker.

3. Heavy soils have been known to bring out darker color tones especially in dark purples.

4. Lighter soils have been known to give lilacs a more washed out or faded look.

5. Any combination of the above factors can give a lilac different shades from year to year.

6. Young immature lilacs can also bloom in lighter shades; not showing their true color for 4-6 years. Lilacs can bloom when they are only a few inches tall the blooms are often bigger than the actual plant. Age does not play a role as to when a lilac will start blooming that is controlled by weather, growing conditions and some say a little lilac luck!
