Planting Advice for Syringa vulgaris Katherine Havemeyer Trees

Our pot grown Katherine Havemeyer Purple Lilac trees can be planted at any time of the year. Start by removing weeds and grass within a metre of your desired planting hole. Dig a square hole as deep as your root mass and approximately 2x as wide. To help the tree establish more effectively, sprinkle root grow in the hole.

Remove the pot, gently tease the roots and place into the planting hole. Mix 50% of the original soil with 50% compost, fill in the hole and firm around gently. Avoid banking the soil up around the collar of the tree. Whilst bush forms of Katherine Havemeyer Lilac do not require a stake and tie support, single stem tree forms do.

Aftercare Advice for Syringa vulgaris Katherine Havemeyer Trees

If you’re planting in spring or summer, water well for the first few months. Increase watering if there are extended periods of hot or dry weather. If planting in autumn, you may only need to water a little. Irrigation kits make it easier.

Once planted, keep the area free of competing weeds and grass for the first couple of growing seasons.

Pruning Syringa Katherine Havemeyer Trees

Pruning is encouraged when it comes to Katherine Havemeyer Purple Lilac trees. If you wish to maintain a bush rather than a tree, allow the side growth to flourish and simply prune after flowering. For a tree effect, prune the longest, oldest branches that lie closest to the ground.

If your Katherine Havemeyer Purple Lilac begins to look overcrowded, remove inner branches to allow more light and air inside the canopy. Always prune dead flowers and damaged or diseased branches.

Mature Lilac trees that have become overgrown can be hard pruned back to their former glory, but it will take time. Never prune a lilac tree back by more than a third of its size. Do this one season at a time, allowing the tree to recover in between. Apply a fertiliser each autumn and again in spring, just before flowering.

The product table at the bottom of the page gives the forms and sizes available for this variety. Please note, photos are a guideline as all plants are unique. Below are definitions of terms:

Supplied Size: Height measured from the top of the pot.

Single Stem / Pruned and shaped: Classic shaped tree with a single stem that has had pruning to help create a beautiful, natural shape.

Top grafted: A height noted next to this form refers to the length of clear stem, which will not grow taller. Only the head of branches will develop. Top grafted trees do not require complicated pruning and are ideal for small spaces.

Multi Stem: A multi stem tree is has two or more stems arising from or near ground level, growing from one root system. Take care to buy a true multi-stem like all ours and not those that are 3 saplings in a pot to cheaply imitate them.

Feathered: A feathered tree has branches from the bottom of the trunk all the way up. These branches can be removed if a clear stem is required.

Bush: A plant with many stems low down, rather than one clear stem.

Climber: A plant that is a natural climber and will be delivered usually running up a bamboo cane, ready to position in the garden.

Standard Tree: A more mature tree with an upright clear stem of approximately 1.8m-2.0m (measured from the soil to the lowest branches of the crown). Standards are available in different forms relating to their girth size (circumference of the stem measured 1m above soil level), not height:

Standard  either 6-10cm or 8-10cm girth, approximately 2.5-3.0m in height
Premium Standard  10-12cm girth, approximately 3.0-3.5m in height
Heavy Standard  12-14cm girth, approximately 3.5-4.5m in height
