Planting

Bloomerang dark purple lilac trees should be planted in areas that have well-drained soil and, ideally, full sunlight. You can plant these trees almost any time of year except for winter, but spring is recommended. Here are steps to take to plant your tree:

• Pull any weeds and remove any turfgrass and debris from the area.
• Dig a hole that is twice the width of your root ball.
• Tease the roots of your root ball gently before placing it in the hole. You want it to sit slightly higher than the level of the surrounding soil if you are worried about drainage. Otherwise, plant it 1-1.5 inches below the soil level.
• Backfill the hole with soil, tamping down to remove any air pockets.
• Water thoroughly, and place a 3-inch layer of mulch.

Growing Conditions

Bloomerang lilac trees are relatively hassle-free.

• Sun and Shade: Bloomerang lilac trees thrive in full sun, receiving at least six hours of direct sunlight per day. They can tolerate partial shade, but they will not produce as many flowers.
• Soil: The trees prefer moist, well-drained, alkaline soil. Soggy soil conditions can damage their roots. A thin layer of mulch can conserve the proper amount of moisture and protect the Bloomerang from temperature fluctuations.
• Watering: Bloomerang lilac trees will need the most water during their flowering season. Water once every 10 days to two weeks from spring until the end of the bloom season, just before the first frost. Your tree will need 2 inches of water so that the soil is moist down to 12 inches. During the rest of the year, water during extended dry periods—if the top 3 inches of the soil start to completely dry—and if the leaves wilt in dry weather.
• Fertilizing: You can fertilize your Bloomerang lilac tree in early spring starting the second year after planting. Apply a fertilizer that is specifically designed for lilacs—these typically have less nitrogen and a higher level of phosphorus and potassium. An NPK value of 5-10-10 does well.
• Pruning: Pruning is not required for your Bloomerang lilac tree—while it can boost new growth, your tree will rebloom either way. If you decide to prune your tree, do it immediately after its first bloom. Doing it in fall, winter, or before the first bloom will cut off the flower buds. If you trim, the rebloom will be delayed a few weeks.
