    My Solomon's Seal is riddled with Sawfly.

    What shall I do with the plant now?

    Hi poppikin, i'm sure you must have looked at this page (see link). If the infestation is heavy and you do not like to use pesticides then I would cut off/down all affected foliage and remove it from site to reduce the problem next year. Blackstart https://www.rhs.org.uk/advice/profile?pid=698

    Thanks Blackstart.

    Yes I had read the link but I do like personal experiences. I suppose it depends on whether Mr (or Mrs) Sawfly has long gone. Has it? I don't like using pesticides but I do keep Provado for "needs must" and find it very effective.

    The plant dies back very quickly and I prefer to do that rather than cut it back. So I think I will spray it and let it die back.

    What do you think?

    Hi poppikin, the larvae are probably in the soil by now ready to hatch next spring and begin the cycle again. Personally I would still remove the foliage and burn/wheelie bin/local tip/ remove it from site and then spray as soon as the grubs appear next spring. Spray often to catch later hatches. Remember, they are always easier/more susceptible to kill the younger they are. Blackstart

    Blackstart I should have said that this is in a pot and I found it like this when went to re-pot it in completely fresh compost and then didn't.

    Would it help at all?

    Wouldn't hurt, but the sawfly seem to find the plants whatever is done to prevent them. blackstart

     I grow a number of these and have few problems with sawfly, I pick them off when I see them, then every 4 or 5 years the leafs are riddled, but the plants come back the next year oK.

    Thank you Nigel.

    I have had this one in a pot for some years and not had sawfly on it before. It does die right back and then comes again well the next year.

    The sawfly here prefer gooseberries.

    I am at last getting round to planting all my pots.

     Diferent species, you will also find them on gooseberry plants and aquilejas. With over 400 species inthe UK there is probably one for every plant you grow. Don't worry about them.

    Sorry Nigel, just my little joke.

    I did worry about them on the gooseberry bushes because they were large substantial bushes and the sawfly stripped them to nothing, fruit and all.
