Christmas .....

We will suspend sending mail orders from Wednesday 4th December, starting again, weather permitting,  from 6th January 2025. Orders placed after Wednesday 27th November will be sent after Christmas. Most of our plants are now under cover, dormant and not looking at their summer best, so we encourage you to look at our eGift Vouchers as an alternative.

Dahlias

Dahlias like a fertile, well drained soil and reasonable moisture levels, just not too dry. They also prefer lots of sun. They are tuberous plants and the fleshy tubers can be prone to frost damage so in cold areas it is often advisable to lift them after the first frost has knocked back the foliage and store the tubers somewhere frost free over winter.
