  • Purple growth on leaves

    I bought 2 fruit bushes last spring they didn't fruit last year, but overwintered finer.
    Plenty of foliar growth .... but now have thick purple growth on some of the leaves - like broccoli.

    Is this normal, if not what is it, and what do I do about it

    It's caused by currant blister aphid. If you look under the leaves, you'll see small green aphids. These aphids release a chemical as they feed, which causes the blistering.
    Despite the rather alarming appearance, it's actually pretty much harmless, and can safely be ignored unless you get a really severe infestation.

      If there are ants putting the aphids on the plants a bit of anti climb paint around the stem just above the ground will help a lot.
      Aphids can be sprayed off with water.

          Thanks for that tip, mothhawk. I have ants farming aphids all over our new peach trees and was wondering how to tackle them.
          Location: north-east Spain, where the sun is too hot, the rain too torrential, the hail too big, the wind too windy and the snow too deep. Last frost: usually mid-April, sometimes first week in May. First frost: mid-October.
