Not sure what you can do about the termites in the fence, but if they are just eating the posts and you have space for a repair person between roses, you could have galvanized posts put in and the fence attached to them instead.

I think for subterranean termites at a friends house, they just put down some special spikes. They may sell something similar at Home Depot in your area, no idea about the effects on the roses.

At Home Depot (I think this may be what Kippy's talking about) they sell galvanized things with pointed spikes on the bottom. You can sink them in soil, but it works best to sink them in concrete. On the top end, they have upright braces. You bolt 4 x 4 uprights to those things and they're not in contact with the ground, so far less-subject to termite damage.

I was talking about the galv posts like you would think of for a chainlink fence, only they a bit heavier weight. There are hangers that will support the fence rails. It is fairly common way to deal with bad posts to try and get a few more years out of your panels or to skip wooden posts in building a fence.

Those things you pound in the ground, despite the ad photos, are only meant for short fences....somethign we discovered when using for the base of a garden fence entry arch a few weeks back... (now set in concrete too)

and janegael may have frost heave to consider, being in CT.

Home Depot carries a concentrated termite killer by Bayer Advance that worked for me. I have a wood raised bed in my front yard and had put in a lily bed in front it. Discover the damn termites when I put down the mulch. I used the Bayer Advance stuff which worked. I did have to reapply the stuff, five years later but so far so good. I also read that boric acid (which I use for ants) mixed with a certain type of antifreeze is suppose to work well.

Antifreeze brushed on the outside will kill them and keep them away.

You can buy stuff made for boats that you paint on and the wood absorbs it and hardens. It's a liquid that hardens into like a glue. I forget the name but I bought some at home depot a few years back.

Antifreeze is poisonous to dogs and cats. Keep this in mind if you have pets.

Termites live in the soil and travel to the wood to munch. Treat the soil around the damaged areas. You may need to dig down a bit for maximum effect. I think the Bayer Soil and Turf product would work.

Dig around each post completely, one at a time, replace the soil beneath with treated soil (whether you go chem or organic is at your discretion) and replace the posts that have heavy damage.
