Soil can be improved by adding Ericaceous compost to the planting hole this will lower the lime content and raise acid. If pot planted best choice is John Innes Ericaceous Compost this is a specially formulated sterilised loam based, lime free compost with essential foods for plants such as Acer Palmatum. Also in the coldest areas it may be advisable wrap the pots in a winter fleece or bubble wrap during the coldest months, this will help protect the roots. Re-potting in fresh compost should be considered every 2 years. Ensure an adequate water supply and feed approximately every 6-8 weeks from early spring through to mid-summer
