How fast do lilac bushes grow

Lilacs are fast-growing shrubs available in hundreds of varieties. All lilac bushes are fast-growing shrubs that add at least 6 to 8 inches of growth per year. … Common lilac (Syringa vulgaris) spreads by sending out suckers in all directions, causing some gardeners to consider it invasive.

Trim the plant annually, right after it finishes blooming, to improve vigor. Remove weak branches until you have a clump of seven to 10 stems of varying ages. Thin out top growth to let sunlight into the center of the lilac. New buds will form and the plant will grow faster.

Age: Lilac plants need time to grow before they begin flowering. So, if you have a very young plant, it may not be mature enough to bloom. Most plants start blooming after three or four years but some may take as long as six or seven. The blooms for the first few years will be sparse but should increase with time.

Where to Plant Lilacs. The ideal spot to plant lilacs is in an area with full sun (at least 6 to 8 hours per day)—give them too much shade and they may not bloom. Lilacs also like slightly alkaline, moist, well-drained soil.

Propagating lilac bushes from cuttings is tricky, but definitely not impossible. Take cuttings of lilac bushes from tender new growth in late spring or early summer. Mature growth is less likely to root. Take several cuttings to increase your chance of success.

Fragrant old-fashioned lilacs (Syringa) make a handsome natural hedge, but don’t expect results overnight. Lilacs grow slowly at first and may take as many as 5 to 7 years to fill in and bloom well. They need minimal pruning and look best when allowed to take their natural form.

Root System on Lilac

Lilac roots aren’t considered invasive and as long as you leave enough space between the tree, or shrub, and the structure, there is little risk from planting lilacs near foundations. Lilac roots generally spread one and one-half times the width of the shrub. A distance of 12 feet (4 m.)

Lilac bushes will typically flower without any effort from you. However, if left to grow and spread on their own, common lilacs will eventually only flower on the tops of the uppermost branches.

Although many lilac varieties bloom in midspring, commonly around May, the “Excel” cultivar blooms as early as February or March. Combine this early-blooming lilac with other, later-blooming varieties to extend the flowering period from late winter through late spring, or two near-continuous flushes of blossoms.

Bamboo. Bamboo is one of the fastest-growing plants in the world, so it can create a lush and exotic privacy screen very quickly. Some varieties of bamboo are invasive, so consider picking a slow-spreading, clumping variety, or planting it in large raised planters to keep it under control.

Height/Spread:

The common lilac (Syringa vulgaris) grows 12 to 15 feet tall and 10 to 12 feet wide. There are many smaller dwarf varieties that mature at 4 to 6 feet tall and 3 to 7 feet wide. Japanese tree lilacs (Syringa reticulata) can reach 25 to 30 feet tall.

Here’s the first rule of planting: lilacs need lots of space to grow. If you’re planting a hedge, they’ll need a spot at least seven to eight feet wide and ten feet wide for a shrub. They also need at least six hours of sun a day to have excellent flowering. Provide a well-drained, alkaline soil.

Lilac hedges, with their colorful, often fragrant blooms, provide privacy and beautify the landscape. Plant them as a screen, barrier, property line marker or garden room divider or backdrop.

Evergreen trees are the best choice for privacy screens as they don’t lose their leaves in the winter and protect your yard from prying eyes even in cold weather. Fast-growing choices include cypress, such as the Leyland cypress (Cupressocyparis leylandii) or arborvitae, such as Thuja occidentalis “Emerald Green”.

The single most effective way of speeding up the growth in plants is plant fertilizers. Plant fertilizers vary in terms of their NPK composition. Generally speaking, nitrogen aids new green growth, phosphorus builds strong roots and flowers, and potassium ensures strong and healthy plant cells.

Lilacs do not contain any chemicals that will poison animals or humans, nor do they irritate the skin. Even though lilac stems, leaves, and flowers pose no health threat to dogs, it is a good idea to keep your dog from chewing on the plant.

Lilac Attraction

With brilliant purple and bluish petals, lilacs attract numerous bees, especially since the flowers grow in dense clusters. As a result, bees can stay on the blossoms for even more nectar nourishment without having to fly constantly to other plants.

Grass clippings and coffee grounds can be used as a good source of nitrogen. Use sparingly, as too much nitrogen in the soil will result in poor blooms. Lilacs grow best in slightly alkaline (6.5 to 7.0 pH), moist, well-drained soil. Adding bone meal to the soil can make it more alkaline.

Squirrels sometimes strip the bark from the lower portions of lilac trees. … The creatures might by trying to access the inner bark of the shrubs, which contain nutrients their diets lack. Sometimes enceinte squirrels don’t eat in the days before they give birth. Stripping bark might quell hunger pangs.

Herbaceous peonies and tree peonies (Paeonia) are wonderful companions to lilacs. They are compatible in color, fragrance and form, and make each other look better. Plant peonies at your lilac’ foot to hide its poorly clad legs and savor the beauty and pervasive perfume they lavish on those who passes-by.

One of the most well-known of the compact shrubs is the Korean Dwarf lilac or Meyer lilac. This diminutive plant is a neat little shrub approximately 4 feet (1 m.) in height and 5 feet (1.5 m.)wide.

Their fragrant white, purple, or pink flowers bloom among dark green heart shaped leaves and are a favorite for gardeners. Although deer will feed on over 700 species of plants found in garden and landscape areas. … Even though lilacs are considered deer resistant, they will nibble on them if no other food is available.

Mice Like Lilacs

No evidence exists that mice are repelled by lilacs. Mice will chew on younger lilacs, so adding them to your garden will — at best — do nothing to help you.

Lilac damage is produced primarily by lilac borer larvae, which feeds on the sapwood of the plant. Scale insects are another lilac pest, which damage lilacs by sucking the sap from the leaves, stems and roots of the plant. … The adult form of the lilac leafminer is a very small moth.
