What to inspect

For a container-grown camellia, feed in early spring. Camellia japonica belongs to the group that flowers in late winter and early spring.

What changes it

Do not feed camellias later than the end of July. RHS warns that excessive and late-summer feeding can lead to bud drop.

Follow the product label

Fertilizer type and dose

Use an ericaceous fertilizer for a container Camellia japonica. RHS names soluble azalea, camellia or rhododendron food and Chempak Ericaceous Food as examples.
