Unfortunately carrot flies thrive in moist and mild climates – just like ours and our countryside provides many wild plants, such as cow parsley, which the carrot fly is attracted to.

If it seems to work I am tempted to water the site of next years carrots all winter with coffee, hoe before planting and continue watering whilst growing. It can do no harm and is natural. The packet also suggests mixing radish with carrots and pulling radish when ready to thin the row - sounds good but I guess might still let the fly in
ReplyDeleteIt will be interesting to see if the coffee ground idea works.
ReplyDeleteThey also say that onions planting alongside carrots is a deterrent but then this is qulaified by saying you need 5 times thae amount of onions to carrots and that it is only effective whilst the onion leaves are actively growing.
I think you are right about pulling radish possibly drawing in the flies as presemably you would disturb the carrots in the process. Covering so far is the only thing that has worked for us so we will keep doing this as home grown carrots are worth the effort.
