Rooting Cuttings - dark atmosphere for the root end help?

I've read about cloning setup folks use to clone plants and some emphasize to light-proof the cloning tub so the ends you're attempting to get roots to grow from are in complete darkness. Is this a general rule to follow to help your cuttings root sooner?

I had four thyme cuttings in this glass for roughly a month(I think) and only one of them developed roots...

It's better than nothing but I am always looking to improve my technique. :) Appreciate any input.

You can wrap a cylinder of heavy paper, or even black plastic, around the clear container. Just use tape to hold it together. :)

Plants generally seem to like bottom heat to help grow roots. My recent experience growing sweet potato slips has led me to believe that tucking the glass inside a black plastic pot and positioning on a sunny windowsill to take advantage of solar heat might also help rooting cuttings like yours.

Increasing the humidity by covering the top with ventilated plastic (just like with starting seeds) should help too. My favorite method is plastic water bottles with bottoms cut off and cap removed. There's usually a right kind of bottle size/design that if you cut it at just the right place, will fit snugly over any container. 8)

The classic horticultural "propagation tray" consists of bottom heat (heating wire) in the bottom of a 6" deep wooden tray filled with moist sand, and overhead misting system. Don't have anything fancy like that myself, but I thought I'd mention it. :wink:

BTW, if the mother plant is yours, thyme propagates easily by ground layering -- lay the longer shoots on the ground (or on surface of the soil in same/another pot) and dump some soil over the stem touches the soil. Sever from the mother plant once roots grow along the stem. :D

Great info - thanks, applestar! Thinking a 2-liter bottle, cut about 1/3 the way up, filled with some sand in the bottom will do nicely. Jam the top half onto the bottom half... leave the cap off. The sand would keep it dark.

I put some gardenia cuttings in a 2-liter bottle with some sand and they're doing well.

I made a slit about 2" down the side of the bottom piece so it can fold in and I can put the top on for my mini greenhouse.

Shoots are doing well it seems :)

Make a point of removing those yellowed leaves -- in the humid atmo they can get moldy, etc. Looks like another good way to reuse those bottles, eh? :wink:
Keep us updated on progress please. :D

Will do that. Nice to reuse if possible vs hitting the recycling bin.

Will do!

The cutting on the left is doing well. The flower bud that was on it even bloomed (vs falling off) which was cool. I snipped the bloom off though as I think it was starting to get moldy. Did smell nice for a while. :) The cutting to the right has put out new shoots.

I keep watching the sides and bottoms for signs of roots but none yet.

Roughly four weeks since cutting and potting these Kleim's Hardy Gardenia cuttings and we have a visible root! :)

Not sure how long I need to wait to pull this one cutting and put it into soil?

Appreciate any input.

I would say, the longer you wait the better. The last thing you want to do is pull out the plant and risk damaging young roots, only to have it die on you in its new home! Wait until the shoots start growing more vigorously, and that will mean it's getting a good foothold. Once it roots well, it should really start to take off.

I waited six weeks and figured it was time since I was seeing some pretty solid roots. Flooded my container to loosen the sand and removed my rooted cuttings for potting.

This one has roots about 1.5" long...

The other one, which I failed to get an image of, had shorter but stout roots around 1/2"-3/4" long.

Potted these up in some perilite/potting soil mix and ready to watch them grow. Once they get going, I'm going to give one to a neighbor. Also, I took three cuttings tonight and potted them to root them. :)

Of the two cuttings I rooted, one is doing well. I had both potted up in soil and by the window. One of them(better developed root system) was a bit too much in the direct sunlight and it did it in. The other is doing well under a grow lamp...

[img]https://somegeek.home.comcast.net/somegeek_rooting_8.jpg[/img]

I checked the roots today and decided it needs more soil to stretch out into...

Planning to keep this one small(bonsai style) and in my office.
