When it comes to managing overgrown shrubs, sometimes cutting them back to the ground is the best option for restoring their beauty and fullness of foliage – and this includes lilacs! While it may sound intimidating, it is actually quite easy – under the right circumstances – to rejuvenate your lilac bushes by cutting them back to within 12 inches of the ground, also known as ‘ground pruning’ or ‘rejuvenation pruning’. Read on to find out more about when and how you should go about pruning your beloved blooms!
Reasons why cutting lilac to the ground can be beneficial
Pruning a lilac bush down to the ground can be a great way of revitalizing an overgrown or leggy bush, as this will reduce its height, encourage fuller foliage growth and provide you with more blooms in the springtime! Pruning also helps improve air circulation which in turn helps reduce disease problems, as well as helping with pest control by removing areas where pests tend to hide and breed.
Shrubs that are suitable for ground pruning
Not all shrubs are suitable for cutting down to the ground, but luckily most species of lilac (Syringa vulgaris) are – including French hybrids such as ‘Katherine Havemeyer’, ‘Monge’ and ‘Josee’. Other varieties may not respond so well, so make sure you do some research beforehand if you’re unsure about what type of lilacs you have in your garden!
When to prune lilac shrubs
Lilacs should be pruned in late winter when they are dormant; this is usually between late February and early March in temperate climates. If you live in an area with cold winters then wait until late March or April when temperatures begin to rise again before attempting any type of major pruning work on your bushes!
Tools needed to perform the task
The tools you will need depend on how much work needs doing – but generally speaking all that is required is a pair of sharp secateurs, loppers and/or a small handsaw (if necessary). A ladder may also be beneficial if you have tall shrubs that require more extensive pruning work at height! It is important that all tools used are clean and sharp – dull blades will cause more damage than good!
Step-by-step instructions on how to prune a lilac shrub correctly
1) Start by removing any dead or diseased branches first; these can easily be identified by their lack of foliage or discolouration. Then trim away any crossing branches or those which rub against each other, as this can cause wounds which could invite pests or disease into your plants!
2) Next cut back any branches which are going beyond 12 inches from the base of the plant (the trunk); this will help encourage new growth from lower down on the plant which will create a fuller look overall.
3) When cutting away large branches use loppers or saws (if necessary), taking care not to leave any stubs; these can become entry points for pests or disease-causing fungi!
4) After all major cuts have been made use secateurs for finer shaping work; make sure that each cut is angled slightly downwards towards an outward facing bud so new growth is encouraged in that direction instead of towards other parts of the plant!
The difference between pruning and shearing
Pruning is often mistaken for shearing but they are two very different techniques; while both involve cutting away foliage they achieve different results: Pruning encourages new growth while shearing simply removes existing foliage without taking into account where buds are located on the plant or encouraging new growth from lower down like with proper rejuvenation techniques like mentioned above!
Tips for ensuring proper aftercare for pruned lilacs
After cutting down your lilacs make sure you give them an appropriate aftercare regime; this includes watering regularly during dry spells, mulching around roots during springtime (this helps retain moisture) and occasionally feeding with an organic fertilizer such as compost tea or liquid seaweed extract in order keep them healthy during their recovery period!
How long it takes for a Lilac bush to recover from pruning?
It usually takes around 3-5 years before a fully grown bush has recovered its original beauty after being cut down so far back – but don’t worry, within one season there should already be noticeable signs of regrowth starting at the base where all major cuts were made!
What To Do If A Lilac Shrub Does Not Respond Well To Ground Pruning?
If after two seasons there appear no signs of regrowth then try using root stimulants such as mycorrhizal fungi products; these stimulate root development which should hopefully result in new shoots appearing eventually! If after trying these methods there still appears no sign of regrowth then unfortunately it may be time for replacing your shrub altogether…
Rejuvenating your overgrown or leggy Lilacs by cutting them back within 12 inches from their base is known as ‘ground-pruning’ and can lead too healthier, better looking plants over time – provided they’re given appropriate care afterwards! With our step-by-step instructions above – along with some tips on when and how – you’ll soon have beautiful blooms growing again in no time at all – happy gardening everyone!!
