rose cuttings put out leaves, then leaves die

| I use Rootone for my cuttings, put them in potting soil, then put them under a grow light about 8-10 inches away for 8 hours day.
After the rose stems put out 3-inch stems and leaves, the stems and leaves wither and die. I water lightly once a day.
I am baffled about what I should do with the next batch of cuttings.
Can anyone suggest anything? My cousin gave me the cuttings, and I think that they came from the end of the branches.
Thanks.

| You need to determine why they are dying. The cutting putting out leaves means nothing--there is enough stored carbohydrate in the stems to enable a cutting to put out a few leaves without growing any roots at all. So, is the bottom of the cutting rotting (black, slimey) or is the cutting just drying out? Determining one or the other will tell you what to correct. If the cutting is rotting, they are too moist. If they are drying out the humidity is too low for them. I do cuttings in barely moist potting soil but put them in a soda bottle to hold in humidity. Everything has to be clean, and the potting medium must be sterile, so mold and fungus doesn't form. But the cutting will live until it roots, even if it takes a couple months. |

| The cuttings just seem to be drying out. They are in pots. How can I make the environment humid enough? Should I buy some pop bottles, throw out the pop, and use the bottles as you do? Thanks. Paul |

I use empty 2 liter clear pop bottles to hold the smaller pot with the cuttings. Like HoovB says, make sure everything is sterile. My last batch of cuttings was put into used coir and I got a bad growth on it. Now, I am going to put my coir in the oven before it gets reused. My next problem is having the potting soil too wet. Make sure it is well drained.

I suggest read George Mander's thread. I think ur cuttings have no roots. Pull one up and check. If they do have roots on them, then the roots must have rotten from too wet.
