How to Grow and Care for Bloomerang Lilac

Bloomerang Lilac Care

Here are the main care requirements for growing Bloomerang lilac.

• Plant in well-draining, neutral soil with full sun.
• Water moderately, but more during long periods of dryness.
• Fertilize twice in the spring; once when the grounds thaws and once again after the first bloom.
• Requires an extended period of cold weather to bloom.

Light

Bloomerang lilacs do best in full sun. They tolerate partial shade but will not produce as many blooms.

Soil

Like all lilacs, Bloomerang prefers soil that is rich in organic matter. The soil should be neutral to slightly alkaline. Lilacs do not like acidic soil (pH 6.5 or lower). Good drainage is essential; lilacs do poorly in soggy, wet soil.

Water

Mulch around the base of your lilac to retain moisture. In long dry periods, water it moderately but regularly when the top inch of soil feels dry.

Temperature and Humidity

Like most lilacs, Bloomerang needs an extended period of cold winter weather to bloom profusely. This makes lilacs unsuitable for hot climates. While Bloomerang lilac can be planted as far south as USDA hardiness zone 7, it is best grown in areas with cooler summers. In areas with hot summers, the lilac fares better in locations that provide some shelter from the strong afternoon sun.

The shrub is not affected by humidity unless the weather is very hot and humid, which will slow down reblooming.

Fertilizer

Fertilize Bloomerang lilacs twice, the first time in early spring right after the ground becomes soft, and a second time after the spring bloom to give it a good boost for the continued summer bloom. Use a fertilizer that is high in phosphorus to encourage blooming, and avoid fertilizers that are high in nitrogen because too much nitrogen encourages foliage growth but not blooms. For the amount to use, follow product label instructions.

Types of Bloomerang Lilac

• Bloomerang ‘Pink Perfume’ is a standard-sized cultivar with pink flowers.
• Bloomerang Dark Purple ‘SMSJBP7’ is a standard-sized cultivar with dark purple flowers.
• Bloomerang Dwarf Pink ‘SMNJRPI’ is a compact cultivar that reaches only two to three feet in height and spread. It has pink flowers.
• Bloomerang Dwarf Purple ‘SMNJRPU’ is a compact cultivar with purple flowers.

Pruning

Bloomerang lilacs bloom on old and new wood (last year’s stems and this year’s new stem growth), and because of their fairly small size do not require regular pruning. If you want to shape the plant, prune it with sterile garden pruners immediately after flowering. For a neater appearance, remove spent flowers right after flowering in spring, but it’s not essential. Never prune Bloomerang lilacs in fall, winter, or spring during flowering because pruning at that time could remove developing flower buds.

Propagating Bloomerang Lilac

The cultivar is a registered trademark and propagating it by cuttings or seed is prohibited by a plant patent. Only the breeder is allowed to propagate this series of lilacs and sell them under the name Bloomerang.

Potting and Repotting Bloomerang Lilac

Unlike common lilac and other larger lilac species, Bloomerang lilacs can be grown in containers, especially the dwarf varieties. Keep in mind that lilacs, even compact varieties, have an extensive root system. The container should be large, at least 18- to 24-inches in diameter.

Before you start, review these common container gardening mistakes, such as filling a container with potting soil before it is placed in its final location. An 18-inch diameter container for a Bloomerang lilac holds about 15 gallons of soil and moving it after you planted it can be cumbersome. Make sure your container has plenty of drainage holes that allow water to drain thoroughly and prevent root rot. Also, stay away from plastic containers that hold too much moisture, and choose wood, concrete, or resin pots for this plant. If you live in an area with cold winters, avoid terra-cotta pots, which may crack when contents expand during a freeze.

Sufficient watering is crucial to keep your Bloomerang lilac alive and blooming. Follow the guidelines for watering container plants.

Overwintering

Lilacs are winter-hardy shrubs but you can choose to give new plants a bit more care to get them through a frigid winter. Protect young plants with a good watering before freezing followed by a layer of mulch over the roots after the ground freezes. If a late winter or early spring ice storm or arctic blast is predicted, cover the plants to protect fragile buds. Remove the covering as soon as the weather warms again.

Potted Bloomerang lilacs will benefit from some winter protection to keep roots from being exposed to freezing and thawing cycles. Move the container into a protected area outdoors or in an unheated outbuilding but do not bring a lilac indoors. They need that cold weather exposure to set buds for best flowering.

Common Plant Diseases

Bloomerang lilac is more resistant to powdery mildew and leaf spots than common lilacs, but it is not immune to the problem. Because powdery mildew, a fungus, thrives in humid weather, ensure good air circulation in and around your Bloomerang lilac by giving it enough space to mature. Plant shrubs at least 5 to 6 feet apart.

How to Get Bloomerang Lilacs to Bloom

Bloomerang lilacs are meant to easily bloom and then rebloom. The spring bloom is different from the summer and fall bloom when the panicles are smaller and darker in color than in the spring. To make sure your Bloomerang reblooms, it needs to grow well in the late spring and early summer.

Bloom Months

Bloomerang lilac starts blooming in May, and pauses in June. It blooms again in July through the first frost of the year.

How Long Does Bloomerang Lilac Bloom?

Hybrids like the Bloomerang lilac are cultivated for best performance and disease resistance, therefore, they bloom until the first frost, or for about three to five months, give or take the climate of the area.

What Does Bloomerang Lilac’s Flowers Look and Smell Like?

Bloomerang lilac’s flowers are pink and purple and smell very sweet.

How to Encourage More Blooms

During the spring and summer, keep your shrub moist and give it six hours of daily sun for the best fall flowers. Lightly fertilize before and after the spring bloom and very lightly prune the shrub after its spring flowering. These two things should encourage more new growth which will help maximize late summer and fall flowering.

Caring for Bloomerang Lilac After it Blooms

Bloomerang lilacs can be planted as a specimen plant, in small groups, or as mass plantings. If your shrub is in a container, make sure the pot is large enough and the plant is not root bound. A crowded, root-bound Bloomerang lilac will not be happy and won’t bloom very well. After blooming, water your Bloomerang lilac every 10 days to two weeks until the first frost.

Deadheading Bloomerang Lilac Flowers

By pruning you may run the risk of eliminating developing buds. For best results, go slowly and snip off a part of a branchlet just beneath the spent flower.

Common Problems With Bloomerang Lilacs

Bloomerang lilacs remain relatively healthy except for powdery mildew that can cause disfiguration of the leaves. This hybrid is robust, however, and the mildew is more of an aesthetic annoyance and does not usually have any effect on the shrub’s growth and bloom. Use a fungicide to control the mildew and rake up leaves around the plant annually.
