REFRESH PLANTS IN CONTAINERS
Long-term container plants will benefit from some attention now before starting into growth again.
1 GIVE THEIR ROOTS MORE SPACE
Plants that have been in the same container for several years might well have become pot bound and need moving into a slightly larger container. Gently tip them out from their existing pots and tease out roots to encourage them to spread out into their new home. Trim away old or dead roots.
2 REFRESH THE COMPOST
If you can’t move them into a larger pot it’s still worth taking out the plant with as much of the old compost as possible and cut away old roots. Then repot in the same container with fresh compost and slow-release fertiliser.
3 TOPDRESS AND FEED
Container plants that don’t need repotting yet should have the top 5cm (2in) of compost scraped away. Replace it with fresh John Innes No. 3 compost and add a sprinkling of slow-release fertiliser.
