What NOT to plant!
Tender summer bulbs such as cannas, dahlias, begonias, eucomis or zantedeschia.
Tender exotics such as colocasia, aloes or tree ferns
Summer bedding plants such as pelargoniums, petunias or lobelia.
Half-hardy annuals such as cleome, zinnias and cosmos – sow these in late spring to get their best performance.
