How to establish your Syringa Clarkes Giant?

Plant Syringa 'Clarke's Giant' in full sun.

For the best flowering:

Choose a position with at least six hours of direct sunlight daily.
Plant in an open area with good air circulation.
Avoid heavily shaded positions, as flowering will be reduced.

How to maintain your Syringa Clarkes Giant once established?

Water regularly during the first growing season while establishing.

Once established, 'Clarke's Giant' is reasonably drought tolerant but benefits from occasional deep watering during prolonged dry periods, especially while flower buds are forming.

Feed annually in late winter or early spring with:

Compost or well-rotted organic matter.
A balanced slow-release fertiliser for flowering shrubs.

Avoid excessive nitrogen, which encourages leafy growth at the expense of flowers.

Prune immediately after flowering.

For best results:

Remove spent flower heads.
Remove dead, damaged or crossing branches.
Every few years, remove one or two of the oldest stems to encourage vigorous new flowering shoots.

Avoid pruning during winter, as next season's flower buds develop on the previous year's growth.

Lilacs require winter chilling to flower reliably and perform exceptionally well in cooler parts of New Zealand.

'Clarke's Giant' is highly frost hardy and thrives in areas with cold winters.

Apply mulch around the base each winter, keeping it away from the trunk.

This variety is generally healthy and low maintenance.

Aphids
Scale insects
Powdery mildew during humid summers

Good airflow and sensible pruning will help minimise disease problems.
