when i sow seeds in soil the sprouts are extraordinarily leggy (the stem under the first two leaves is too long) after 4/5 days these start falling down and die may I please know the solution

Hi Every one,
I'm brand new here, and I have two questions that I hope to get some help for. My most pressing is, what is the most effective yet least toxic way to prevent damp-off in my rose seedlings? I've tried the 1/19 hydrogen-peroxide to water drench with some success, but don't know how often to use it. ( oops, here's another seedling question. Should I sterilize the commercial seed starter before I plant? thought it would have been already, maybe not.)The other question is, where to find rare roses that are grafted. I'm all for own root roses for old and robust shrub varieties, but where I live, Hybrid teas and floribundas do better grafted on robust stock and planted deep. I'm specifically looking for Smokey and Jocelyn, also other marvelous and strange colors ( have you seen Paul Bardens photo of a striped Jocelyn? GORGEOUS!!!!).
Thank you very much for taking time to help!!!!

I have a problem - my roses are dying! Included in the moribund ones are Spring Gold, John Cabot and Champlain.

Symptoms - the leaves gradually fall off till the plant is bare. There is no evidence of Rose mosaic virus.

Although I suspect some other type of virus, I don't know - maybe it is some soil deficiency, as they have been up to 12 years in the same location, fertilizer having been applied regularly, but no exotic additives such as iron.

The leaves look fine until they drop off; inflorscence is greatly reduced; no insects are visible.

I'm stumped!

In late March once the snow receded I discovered the canes of four well established roses
lying flat on the ground. Voles or some other underground residents devoured the entire root ball and stems of my plants. They are 100% destroyed.

I'm wondering if I should replant in the same area. The damage went unnoticed as it all went on beneath the snow line. The canes didn't fall over until the spring:)

Is there a gardeners trick against voles? Should I pour used kitty litter over the area?
I've plugged the stems into the ground and am hopefully on my way to recovering, or at least trying to recover one or two of the three varieties I've lost. Wish me luck!
