watering

Lilac (Syringa chinensis 'Lilac Sunday') should be watered once every 7-10 days during the active growing season (April-October). During this period, water deeply enough so that the top 6-8 inches of soil are moistened. Avoid frequent, shallow waterings that only wet the surface of the soil as this can easily lead to root rot. A good way to test for proper water depth is to take a spade and dig 6-8 inches into the soil – if the soil appears damp, you have achieved sufficient water depth. During the dormant winter months (November-March), moisture levels should not be maintained – water sparingly, only when the top inch or 2 of soil is completely dry.

sunlight

Lilac (Syringa chinensis 'Lilac Sunday') thrives best in full sun and needs at least 6 hours of direct sunlight per day. This may vary depending on the climate it is grown in, as more sun may be needed in hotter regions or during the peak of summer. During the spring and fall months, the plant may be able to get away with slightly less sun without compromising the health of the plant.

pruning

Lilac (Syringa chinensis 'Lilac Sunday') should be pruned twice a year; once after the blooming has completed in the spring and then again during the fall season. Pruning should be done lightly to thin the lilac bush and should not involve removing large branches or too much of the bush. To thin the lilac bush, any branches that cross over, are broken, dead, or diseased should be pruned out. Additionally, for larger lilac bushes, removing 1-third of the older, thicker branches each year will help encourage new stem growth. It is important not to prune more than 1-third of the bush in 1 season, as this may cause shock and delay blooming the following year.

FAQ

Are lilacs popular in gardens?

Yes, lilacs are very popular in gardens. This is because they are reliable, attractive, and easy to care for. They come in a variety of beautiful colours and can be grown as a shrub or small tree, which makes them perfect for a variety of garden styles. Lilacs are very low maintenance and are known to be quite drought tolerant, which makes them ideal for gardeners who don't have a lot of time to fuss over their plants. In addition, their scented blooms are a wonderful addition to any outdoor area.

How fast do lilacs grow?

Lilacs grow at a moderate speed, with an average mature height of 6-10 feet and width of 4-8 feet. They typically add two to four feet to their height each year depending on soil and climate conditions. They can be pruned to remain smaller and are quite hardy, though they might struggle in a colder climate with harsher winters. They prefer full sunlight and good drainage. With proper planting and care, lilacs can be expected to thrive and reach their mature growth size within five to seven years.

Can you grow lilacs from cutting?

Yes, you can grow lilacs from cuttings. It is an easy and effective way to propagate lilac bushes. Taking cuttings from actively growing lilacs in the summer is the best time. The cuttings should be 8-10'' long and straight-shooting, with several buds on them. Cut the cuttings about a half-inch below the bottom set of leaves. Dip the end of the cutting into rooting hormone and plant it into some moist soil, being sure to tamp it down firmly. Water the cutting well and keep it out of direct sunlight in a semi-shaded area. In a few weeks, the lilac cutting should begin to form roots and the leaves will soon grow fuller.

Are insects are attract to lilacs?

Yes, insects are attracted to lilacs. This is because the sweet scent of lilacs attracts many pollinators, such as bees and butterflies, while the small size of the flowers and structures make it easy for these insects to land. Additionally, the petals and nectaries of the flower are often quite accessible for them to access the sweet nectar inside. It is this combination of scent and accessibility that helps make lilacs popular among numerous types of insects.

How do you propagate lilacs?

To propagate lilacs from a cutting, it is best to select a six to ten-inch stem with 3-5 buds on it. To do this, use sharp pruning shears to cut the stem at a forty-five-degree angle just below an outward-facing bud. Strip off all but two leaves on the cutting and prepare a pot with a well draining potting mix. Poke a hole in the center of the pot and gently insert the cutting. Firm the potting mix around the cutting, being careful to not cover the two leaves. Water generously and place the pot in a bright, indirect light area. It is best to maintain a constant temperature between 65-70°F. In a few weeks, you should begin to see new growth appearing on the cutting. Once the roots become nice and established you can transplant the lilac into the garden.

How do you prevent lilacs from becoming overgrown?

To prevent lilacs from becoming overgrown, it is important to prune regularly. You should prune after every flowering cycle in late spring or early summer, making sure to remove any dead or diseased branches right away. Avoid pruning too severely, as this can cause stress to the plant, and wait for new buds to sprout before trimming too much new growth. Additionally, fertilize in late winter or early spring to help promote healthy blooming and vigorous growth.

Is there a variety of lilac that has double flower?

Yes, there is a variety of lilac that has double flowers. It is called Syringa x hyacinthiflora and is a deciduous shrub which produces an abundance of flowers in mid to late spring. It typically grows to between 4-6 feet in height and has a width of up to 8 feet. It has a somewhat weeping form, which looks magnificent when adorned with the clusters of double flowers. Syringa x hyacinthiflora has fragrant, pink or purple blooms that are arranged in pairs within one cup-shaped flower. The foliage is dark lush green, making the flowers a truly stunning sight when in full bloom.

How long is the average blooming period for lilacs?

The average blooming period for lilacs depends on the variety, but it can range from one to four weeks. The common European lilac blooms for two to three weeks, though some varieties may bloom longer. To maximize the blooming period, it is best to plant varieties with different blooming times.
