Chrysanthemum Growing Guide

Pruning

When the plant reaches between six and eight inches, pinch it out and remove the top growth. This will encourage side shoots and more flowers. Then cut back after flowering to encourage business and increased blooms.

Protection

Chrysanthemum plants are relatively hardy and can withstand temperatures as low as -5°C but can still benefit from some protection during winter. A light covering of organic matter, compost or bark chips will make a strong, protective mulch.

Chrysanthemums can grow up to 15” tall so will need some support. Staking is often required, particularly when the more autumnal weather rolls in. Add some extra protection by ensuring your plants are in a sheltered area.

Disease Management

Chrysanthemums can be quite susceptible to mildew so be sure to keep the soil dry and well drained. It is important to ensure good air circulation too.


Chrysanthemum Planting Ideas

A simple way to plant Chrysanthemums is to utilise their variation and versatility. Plant different coloured varieties close to each other for a real spectrum of colour.

Chrysanthemums grow well in containers and deliver excellent showstopping impact.

They grow well with classic bedding plants, like pansies and violas. These are a great way to surround Chrysanthemums with even more colour!

Many perennials make a good partner for Chrysanthemums, and foliage plants add a balanced contrast with ‘showier’ varieties.
