I'd be surprised if it didn't grow back even it was cut off at ground level. Anything above the break can be cut into segments for propagating new vines. The length of each cutting should be around 4 nodes, I think, with 2 nodes buried and 2 above the rooting medium/soil.

It will grow, don't fret! I planted 96K (full sun) this spring with no underground system and I wasn't about to drag hoses around. We had 2.5 weeks of no rain as soon as I planted and then a batch of heavy thunderstorms that washed 1/3 of my seed away. It came in semi thin with loads of crabgrass and other weeds. I hit it with Bayer advanced weed killer this summer and that killed off most of the weeds and slowed the crabgrass. I haven't fertilized at all. I just overseeded it during the last week of August and I have sprouts everywhere. I'm going to apply a winterizer next month and a very thorough pre-emergent in the spring and I'm quite certain I will have a beautiful 5 blend tall fescue lawn next year. It already looks very nice (tall fescue = super deep green...even in drought) but nowhere near what it will be. I'm guilty of abuse by most standards and recklessness by some but my yard is coming in fine and getting better by the week. Just relax a little and enjoy the new growth.

I used to grow bananas. Delicious! A fresh home grown banana beats a store banana every time. But then you have to cut down stalks after they fruit. And they are heavy. I couldn't drag them and nowhere to let them rot. I tried chainsawing them and got a bath when all the water in the trunk doused me while I was sawing through them. Who knew there was that much water in a banana stalk? Then I saw a show on banana farms where a big guy cuts them down with a monster machete with one whack and they rot where they fall. There are wires between the rows of plants that run from poles and the bananas are clipped to these lines and slide along to the end where they go into a box. I could not figure out what to do with my old stalks and the weight of hauling them off was too much to pay at the local disposal station. But I did love growing bananas. Now I have figs instead and it's much easier. As far as dogs visiting. You might try my idea of society garlic and ground cover thyme. The dogs don't like the scent and wander on to the next grassy place. I have not had to clean after dogs since I changed the grass for strong scented herbs. I am getting ready to move some big plants between Christmas and New Years and I will be feeling it I'm sure. A warm soak or a shower feels so good after a big day of physical gardening. Poor old blind goose

OMG,That is sooooooooooo funny,caught me completely off guard and literally had me LOL. Thanks Kathi
