SOME may disregard this North American tree as the suckers can pop up all over the place, but if you remove them close to the base of the plant, it can be kept in check and the glorious autumn colours it produces will be well worth the effort.
Highly favoured as a small courtyard tree, it can eventually grow to around 6m, the red-hairy stems with large pinnate leaves turning fiery red, gold, purple and orange in autumn. The effect is greater when set against the dense cones of red fruit borne by female plants. It's an excellent specimen for small sunny gardens, but avoid planting it too close to the lawn because of its suckering habit, or surround the roots with a non-perishable barrier, which will restrict the plant's spread.
WHAT TO DO THIS WEEK
:: Clear fallen leaves and recycle them to make leafmould.
:: Prune rambling and summer-flowering roses.
:: Cut off the top growth of dahlias when blackened by frost. Lift and dry the tubers for storage.

:: Reduce food given to pond fish.
:: Cut off deteriorating foliage from pond plants before it falls into the water.
:: Clear away tomatoes, peppers and aubergines which have finished cropping in greenhouses and put them in the compost bin.

:: Divide overgrown or congested clumps of perennials , unless the soil is sodden or really dry.
