Note: Bacterial pathogen Xylella infects more than 500 plant species including crops, ornamental and wild plants and trees. In Italy alone, over one million olive trees are dying because of a Xylella-transmitted disease. So far Xylella has not been reported in the UK, but there is a heightened risk of its being accidentally introduced. Read more here.

Ajuga Ciatlins Giant failed after one season

Question from Keith

We have two parallel flower beds planted out 18 months ago with a large variety of plants. We have two lots of ajuga 'Caitlins Giant' in both beds. Around last autumn/winter the two lots on one bed started to die off but on the other bed they are now in full bloom. They don't get a lot of sun but all other plants in both beds seem to be OK. All were kept well watered during the dry spell last summer. Soil was well prepared before planting. Wondered if anyone could suggest why these might have died off.
