Lilac bushes are a common member of the olive family and popular for their ornamental beauty. The most common colors in which you can find a lilac bush are lavender, blue, white, lilac, purple, and burgundy. Spring is the season when lilac bushes bloom in full mirth.

 

However, in order to thrive, they require a very particular type of environmental conditions. This includes full exposure to the sun, loamy soil type for growth, and care by pruning and splitting when required. Although they require water to grow as well, care must be taken to keep the soil around them well-drained. Lilac bushes can easily grow and expand as their shoots extend out of the main plant. Later, they can be pruned or split if you know how do you split lilac bushes.

Why Is There A Need To Split Lilac Bushes?

The cutting of lilac bushes at regular intervals stimulates new growth in the plant. It also encourages the flowers to remain in bloom for a long period of time. Splitting the lilac bushes at regular intervals during a year also ensures that the dried and dead branches are removed from the plants, making them look fresh and beautiful at all times.

 

When Is The Right Time To Split Lilac?

The best time to split the bushes of lilac is when they do not produce any more flowers and when the existing flowers turn brown. It is during this time that the new shoots come up and can grow well for the next flowering season. You can split a lilac bush during the spring or autumn season, which is when the plants bloom the best. It is during this season that the soil is usually moist and easy to dig.

 

Compared with the favorable weather conditions and the fast growth of the lilac suckers, early spring is also a great time to split the bushes and propagate new lilacs from the suckers.

 

Lilac shoots are the easiest to transplant after the splitting of the bush. To decide on how to divide lilac bushes, all you need to split a lilac bush is a shovel, a pair of pruners or pruning shears, and some rocks. Additionally, you also require a lot of water, sunlight, fertilized soil, and compost to help the transplanted lilac bush to grow and bloom well.

• Alternatively, you can choose a low-lying branch of the lilac bush and place it in a well-dug ground with rocks and compost without separating it from the parent plant.

• Always plant lilacs in a fertile, humus-rich neutral to alkaline soil, with a pH between 6.5 to 7.0.
• You must also add compost to enrich the soil when growing new lilac bushes from a split bush.
• Ensure that the transplanted bush gets enough sunlight and remains hydrated at all times for it to bloom well.
• It is also recommended to plant multiple lilac bushes around five to ten feet apart from each other.
• After splitting and planting new bushes, put a layer of compost under the bush and add mulch to it, so that it retains any moisture and controls the growth of weeds.
• When splitting a lilac bush, remove any dead branches, leaves and old shoots.
• If your lilac bush is very old, it is recommended to cut down the oldest branches by one-third of their height thrice every year, so that new shoots can grow faster on them.

On the other hand, letting it overgrow and proceed beyond the flowering period can lead to the termination of young developing buds. Therefore, splitting ensures optimum buds for the next season.
4. Lilac bushes are quite hard in nature. With the right amount of splitting, the next growing season would see a stronger lilac growth with greater quality produce of flowers while retaining the best quality buds.
5. In winters, lilac bushes are prone to damage. To ensure that the damaged areas do not affect the growth of the rest of the plant, they need to be split.

 

After looking at the pros of splitting a lilac bush, there might still be questions like can you split a lilac bush without knowing the whens and hows. The thing about splitting is that this process needs precision. Therefore, it is important to also understand why this process may have its disadvantages.

2. There could be a lack of flowering during the growing season if the lilac bush pruning is postponed till late summer.
3. Careful use of fertilizer is advised as excessive use may prevent flowering.
4. Winters might cause damage to stems and a missed pruning can lead to lack of flowering and spread of damage.
