Re: little colour foliage this year

Hi, Lou,
Are they planted in full sun? Sun is usually the key for Nandina colour. They need in minimum of 6 hours, better to have 8 hours of full sun each day. They tend to colour and fruit less in the UK. Other thought is the climate where you live. Though you will read/hear differing opinions, Nandina will dieback/suffer if too cold (above USDA zone 7a or 6b) but do like cool temps to produce the best colour. Also, they need regular moisture. Finally, have you spotted any pests? I don't think feeding is the problem - some cultivars won't turn red if fed.
