well I dont get putting it in powder, and then sticking it into water.. Wont all the root powder wash off?
I think the entire point of the method described in the original post is that all you need to do is 1) cut a cutting from mother plant 2) sit cutting in water 3) watch for root growth. There are MANY methods for cloning, but as the OP says, this is the EASIEST method.
The original post gives tips about how to take the cutting, and how to put cutting in water, etc. What it doesn't say is "use a rooting hormone". If you want to use a rooting hormone in gel or powder form (which is the most popular method for cloning), then you DON'T want to use the "window sill method". If you'd feel better adding some type of a hormone, see my comment below about Willow Water.
I'm not an expert, but I do read closely, and I read a lot. I cloned 4 cuttings tonight using root stimulator (powder form) and potting soil designed specifically for seeds and cuttings. I'm keeping these cuttings under a dome (known as the "dome method").
Here is my version of the "Window Sill Method", with a few addendums:
1) A day or so before you want to clone, fill a clean container with tap water. Set it out at room temperature,
uncovered. This allows the chlorine in the water to evaporate, and the water will be at room temperature when you are ready to use it. (This is what you should do when you water your plants, too.)
2) When you're ready to start the cloning process, first gather together all of the materials you will need. You don't want your newly clipped cuttings to sit around while you are trying to find a razor. Clear and clean a work space next to a sink. You will need the following materials --
a) sharp blade (ex: razor blade, xacto knife, scalpel)
b) rubbing alcohol
c) cotton ball or kleenex
d) clean paper towel
d) mother plant
e) tap water that has sat out for at least 24 hours
f) a clean, opaque container (can't see through it) A shot glass is a good choice.
3) Fill your container 1/2 to 2/3 full with the room-temp water. Set to the side so you don't knock it over, but within easy reach of sink.
4) Saturate the cotton ball or kleenex with rubbing alcohol.
5) Use the saturated cotton ball to wipe the blade you've chosen.
6) Lay the blade aside (but within reach) on a clean paper towel.
7) Now wipe your fingers (especially if you smoke cigarettes!) with alcohol-soaked cotton or tissue.
Look at your mother plant and choose where you want to cut. The lower stems are better for cloning because they have more hormones, so take a cutting lower on the plant if you can. Look for a stem that will form a "Y" or that looks like a mini-pitchfork.
9) When you've decided where you will cut, TURN ON A FAUCET NEAREST TO YOU AND LET THE WATER RUN. The water should be as close to room temperature as possible. Cold or hot water will shock your fragile cutting! You will use the running water in just a minute ...
10) Pick up your sterile razor blade with your nicely clean fingers and gently cut the stem off of the plant.
11) IMMEDIATELY put the tip of the stem under the running water. While the water runs over the tip of the stem, cut it again but this time cut at a 45 degree angle. (I do this on the divider between my two-bowl kitchen sink. It's a perfect little ridge and the water reaches it easily.) Making the 45 degree cut under the running water helps eliminate air bubble(s) from entering the stem.
12) IMMEDIATELY put the properly cut stem into the opaque container.
13) Set the container on a window sill that does NOT get direct sunlight. The natural light and light cycle coming through the window is sufficient for this method, at this stage.
A FEW TIPS:
Don't take all of your cuttings and let them sit while you work with each one. Instead, take one cutting at a time and follow the above steps. It may seem inefficient, but it will reduce the possibility of air entering the stem.
Some people suggest changing the water at various intervals. There are pros and cons to this, IMO. To avoid the cons, you can have a 2nd container "on the ready". The 1st container holds your cutting, and the 2nd container sits and waits until you need to use it. Every other day or so, simply lift the cutting out of #1 and plop it into #2. It will be the exact same temperature and thus cause less trauma to your fragile cutting. While Container #2 is in use, get container #1 ready for the next switch by dumping out the water, cleaning it, and adding new water to it. Both containers should sit side-by-side on your window sill to maintain the same water temperature.
Make sure that the only part of your cutting that is below the water line (meaning, the part that gets wet) is the stem. You do not want any leaves to soak in the water. They will just rot. If your cutting has leaves that are large and/or heavy, cut the leaves in half. It's not pretty, but it won't hurt the cutting and it will help the roots develop more quickly.
You can lightly mist the cutting once or twice a day -- particularly during the winter when you have scorched air blowing into your house from a furnace -- but you don't want any of the cutting that is above the water line to stay wet; You just don't want them to dry out. If they start to dry out, they are likely getting too much sun.
As soon as you see the first little signs of roots -- tiny little hairs -- it's time to transplant into soil and start a 24/0 light cycle. You can put your newly planted clones under a dome at this point for a few days until the roots get stronger.
WILLOW WATER: The "window sill method" works best if you first make a homemade rooting stimulator called Willow Water (different than the powders or gels you can buy). All you have to do is find a Willow tree (or any tree or shrub of the willow family, a group of plants with the scientific name of Salix), take a few thin cuttings from it, and let it sit in a gallon of water for a few weeks.
WEEKS? Yes. Too impatient? There's a solution for that: Just steep the willow twigs in boiling water, then let it sit for 24 hours. It will be just as good as the slow-brew method. Willow bark contains natural plant growth hormones which can be used for rooting new cuttings. It's a tried and true method used for centuries by avid gardners. (I'll post the full instructions in another post with the proper heading.) Your willow water is also really good to use for newly planted cuttings. Just use the willow water each time you need to water the plants. (Don't forget to check the pH)
