You have two options if you’re wondering when to transplant lilacs: spring or autumn. The majority of specialists advise taking action in spring. The best period is right after the plants blossom but before the summer heat really kicks in.
When may a lilac bush be moved without risk?
You’re trying to figure out if you can move your lilac bush. You’ll be glad to learn that lilac bushes are simple to move. Lilac bushes rank among the easiest plants to transplant successfully, according to our research. We will outline the procedures for effectively transplanting lilacs in this article.
The simplest lilac bushes to transplant are the young ones. They are able to quickly adapt to their new environment and put down new roots thanks to their strong, youthful growth. Can a larger Lilac shrub be moved with ease? Sure! Simply put, it requires a little more effort and “TLC” from beginning to end.
The greatest time to transplant lilacs is in the spring. In hot, dry conditions, they do not transplant well. Bushes should be transplanted after their blooming time and before the hot summer months.
It’s vital to remember that transplanting may have an impact on the following spring’s bloom. The bush will probably produce fewer blooms or none at all the next year. They concentrate on re-establishing their root system over the year following their transplant. The lilacs should blossom normally the next year.
How to Transplant Lilac Bushes
The fundamental steps for successfully transplanting lilac plants are as follows:
Lilacs require high, draining soil. When choosing the new location for your lilac bush, keep this in mind. If necessary, add a few inches to the soil’s elevation.
Make a decision regarding whether to cut the bush. Lilacs can have issues with this choice. We advise against trimming a lilac bush. Trimming plants allows the plant to concentrate on regrowing the root system, which goes against the logic of typical transplanting. However, pruning a lilac bush can mean cutting off the blossoms for the following year.
Dig far and deep to remove the plant from its present site. The transplant will be more successful and less traumatic if you have more roots.
In the new site, dig a hole. Create a hole that is roughly twice the size of the root system.
Put the lilac bush’s roots into the hole at the same depth they were at their previous position.
Water deeply and completely. When transplanting, we prefer to use a light solution of liquid fertiliser or seaweed fertiliser.
For three to four weeks, deeply water the soil every day to keep it moist but not soggy. Your roots will be helped to re-establish themselves as a result.
Where do lilacs thrive the most?
When the lilacs begin to blossom, it is a solid indicator that spring has arrived for good. While many people only have a limited knowledge of common lilac (also known as French lilac) shrubs that can reach a height of 15 feet or more, there are now a lot more options available than there were fifty years ago. Some varieties that rebloom enhance the garden’s appeal the entire growing season.
How to Choose Lilacs
The common lilac is what you will most likely find when you go plant shopping. This traditional plant comes in a variety of cultivars and variations, each of which yields fragrant spring flowers in pink, purple, white, or even combinations of those hues. Common lilacs are typically the most fragrant variety of lilac and can grow to be rangy and large.
Rebloomers have arrived in the garden centre thanks to recent introductions of hybrids between the common lilac and other shrub-type lilacs. Some of these more recent types are a little less fragrant, but they also tend to be smaller, bloom more frequently throughout the growing season, and have fewer powdery mildew issues.
The tree lilac is another common variety of lilac. It can grow to a height of around 20 feet and blooms with cream-colored flowers in the middle of the summer. Though it doesn’t require much trimming, keep in mind that the tree lilac is a tree, not a shrub.
Where to Plant Lilacs
Lilacs should be planted in full light (at least 6 to 8 hours per day), as too much shadow will prevent them from blooming. Lilacs also prefer moist, well-drained soil that is slightly alkaline.
When to Plant Lilacs
Before the ground freezes in the late fall is the ideal time to plant lilacs. After the earth thaws in the early spring, that is the next ideal period to plant. Lilacs will likely need to be planted as soon as you can locate them at the garden centre, which is great; if you choose to do so during a warmer season, they might require additional watering.
How to Prepare the Soil for Planting Lilacs
A soil test should be performed prior to planting since lilacs thrive in slightly alkaline (6.5 to 7.0 pH), moist, well-drained soil that is high in organic matter. Lime must be added to raise the pH if it is below 5.5. It’s time to get the soil ready when you’ve obtained the ideal pH. Improve individual planting holes by mixing Miracle-Gro Garden Soil for Trees & Shrubs in a 50:50 ratio with the natural soil to give lilacs a nutrient-rich start. Iron and phosphorus are also present in this garden soil to promote root development and ward off leaf fading.
Are lilac bushes’ roots deep?
Lilac shrub roots are quite rare to penetrate the side of a foundation. Lilac roots typically become damaged when they get too close to the soil-level foundation’s base. Lilac roots can only penetrate shallow foundations because of their shallow root systems. It is unlikely that you will sustain harm if your foundation is deep.
Lilacs can also cause foundation damage if the soil is thick and expands when wet and contracts significantly when dry. When there is a drought, the feeder roots draw a lot of moisture from the soil at the tips, which causes it to drastically shrink and can lead to cracks in the foundation. After a heavy rain, the soil fills once more, but the foundation still has fissures. Regardless of the distance between the foundation and the shrub, damage to foundations is unlikely in instances when the soil is light and the foundation is deep.
There is a slight possibility that lilac roots will obstruct water and sewer lines. Lilac roots choose the easiest route to sources of nutrients and water. They are more likely to enter leaking water and sewage lines than sound pipes, though. However, there is little chance of damage if your lilac shrub is located 8 to 10 feet (2-3 m) from water and sewer lines, even if the pipes are cracked.
Can you transfer a lilac shrub that is fully grown?
Lilac plants provide beauty and fragrance to any backyard garden. They are also adaptable shrubs, serving as specimen ornamentals, border plants, or components of floral hedges.
Instead of moving a lilac bush, think about transplanting a root sprout if you think your lilac will look or thrive better elsewhere. Like the French lilac, many lilac species spread by sending out shoots from the base of the bush.
How well do lilacs transplant? It’s the lilac shoots. They can be dug up and replanted, and chances are strong that they will prosper and grow in the new environment. A mature plant can also be moved in its whole, but only if required. You’ll only need to put in a little bit more time and energy.
Is summer a good time to transplant lilacs?
Plan to transplant your lilac in the late summer or fall, after the plant’s flowering season has ended entirely but before frozen ground makes digging impossible. Depending on where you reside, try to transplant as early as July and August or as late as October and November.
Can you plant a branch that has been cut off a lilac bush?
Lilac bushes might be difficult to grow from cuttings, but it is not impossible. Take cuttings from the fragile new growth of lilac bushes in the late spring or early summer. Rooting is less likely in mature growth. To enhance your chances of success, make many cuts.
When the weather is chilly and the plant is well-hydrated, take cuttings in the morning. Cut tender, fresh growth in lengths of 4 to 6 inches (10–15 cm). Leave two to three leaves on the cuttings at the top after removing the bottom leaves. The nodes—the locations where the leaves were linked to the stem—will produce roots.
Sand, perlite, and potting soil should be added to a pot. Make a small hole in the mixture with a stick or your pinky after briefly moistening it. Plant the cutting in the hole after dipping the bottom in rooting hormone. After that, lightly massage the potting mix around the cutting’s base to help it stand up straight.
If the leaves of the cuttings don’t touch, you can place many ones in the same pot. In celled nursery trays, cuttings can also be planted. Put the saucepan somewhere warm, like the top of a refrigerator. Right now, bright light is not necessary.
If necessary, water the cuttings every day to keep the potting mix moist but never waterlogged. To create a humid environment, you can place a clear plastic bag over the pot; however, you should periodically unzip the bag or poke a few holes in it to allow air circulation; otherwise, the cuttings risk rotting.
In one to two months, the cutting should start to take root, which is typically signalling by the emergence of robust new growth. At this stage, turn the pot to direct light that is bright and let the potting soil air dry for a little while before watering.
Move the lilacs to their permanent outdoor position after allowing them to mature and the roots to become well-established.
