Is this abnormal root condition caused by nematodes??

Sure looks like it. Do you have a microscope?

That is nematode damage. You don't need a microscope to see that. You might want to try growing nematode resistant varieties or use a rootstock that is nematode resistant and graft to it.

Its root knot nematodes. Container gardening will keep them away too.

thanks for all the input folks

Wonder how I got them-- never had any signs prior to this year , I did a few things different than just digging the hole to plant them in, like I added the bags of black cow , brought in some somewhat composted manure from a farm and the like.

Any one know of anything I can put in the ground to get rid of them before the spread to my other ornamentals and fruit trees??


Thanks again

I've been fighting these vicious little buggers ever since I started gardening in our Florida sand and as far as I've been able to learn there is no quick fix for backyard gardeners. Some commercial growers use chemicals that are banned for home grower use (that I wouldn't want to use anyway) and soil sterilization methods using equipment beyond my budget. You can read about inexpensive methods of soil sterilization on the net and might want to try that. Personally I think it's best to develop healthy soil full of beneficial microorganisms in hopes that they will eat the bad guys. That along with planting crops that are non host for root knot nematodes (RKNs) are methods I'm trying but they are long term approaches to the problem.

Is it just possible there are beneficial nematodes to help your problem??
These days they're finding all sorts of new nematodes so it's just possible. Might be worth a search.
I did use beneficial 'todes when I started serious gardening. Useful for cinch bugs, codling moth, wire worms and any soil insect, gets them in the larval stage if applied at the right time of year.
