RAZOR BLADES.

I have success rooting about 80% of my rose clippings. I am sure all of the tricks in various threads help but there is one missing critical piece. The cut needs to be super clean. I use a razor blade at a 45 degree angle.

The outer skin carries water and minerals up the stem. When you have a rough cut, it squeezes closed the little capillaries at the cut end. Imagine cutting a straw. If you use a dull knife or your teeth, it's going to mangle the end of the straw, and it won't be very easy to suck liquid through it. If you use a razor sharp set of scissors, you get a nice clean cut with an open end. The same goes for your water carrying vessels in the rose stem.

Key tips:

1. Razor cut at 45 degrees.
2. Gooey rooting hormone on the end.
3. Break off the leaves and thorns along the part of the stem to plant, and apply root hormone all along that area.
4. Use stems that have just flowered.
5. Use larger stems, and even canes.
6. Use longer stems. They die slowly from the top but don't give up on them until they are dead all the way to the ground. I use stems at least 12" long, and go up to 4' sometimes.
7. Preset the hole with a skinny object, and then gently push the cut end 5" or 6" deep. Again, we are trying not to bungle the cut end.
8. Set up drip irrigation directly on the stem, or at least make sure the soil gets very wet around the cutting every day.
9. Try after the first blooms, but later blooms work too.

I don't bother with the jar or 2 liter bottle covering, but it doesn't hurt.
Regular strong sun.

A point of technicality:
The outer skin carries water and minerals up the stem.
Although still critical, and does not change Teammccalla's point, this is not true.

--- The outer part of the "outer skin" is equivalent to human skin, and has no net up or down movement of water, nutrients or minerals.
--- The major purpose of the inner part of the "outer skin" is to move manufactured foods and chemicals from the plant's upper parts down the stem. The direction of flow in the "outer skin" of a rose stem is down.
--- It is the central parts of a rose stem that conduct water and minerals up.

But what would happen if conduction down the stem stopped? Sure death, and this is why Teammccalla's point, that damaging the outer skin is not good, still holds true.

Welcome! Teammccalla,
Thats pretty much what I do too. I've had pretty good success also. I think the main difference between both of us is the length of the cutting and I keep the cutting in the shade. Also I used just the powder rooting hormone. It gets very hot here. The other day it was 115!

What do you use for the rooting medium?
Sand, perlite/peatmoss?
What proportions?

I've never had success with rose cuttings, but will try again with a
sharp blade vs shears.

Also, what is the name of the rooting gel? I have a liquid, Dip N Grow, and
BonTone powder.

Just checked Amazon, and was amazed to see so many different brands and types of
cloning gels & powders.

I used about 1/3 peat moss, 1/3 perlite, and 1/3 vermiculite. I can't remember the exact name of the rooting hormone right now but I think it root tone. It was about $5.00 or $6.00 at the nursery. I'll try to go find the container tomorrow.

Oops, I forgot to look. *Blush* the last container I bought was Green Light RooTing hormone. I also remember buying one brand that had a yellow label. That's the one I think was named Root Tone.
