I was told coleus is one of the easiest things to grow from cuttings, so I took a couple cuttings. What's the easiest way to get them to root? Right now they are in a cup of water.
Just put them in wet perlite with water? That's it? Sounds too easy - lol
Remove all but a couple of the top leaves, remove any flower buds that might be growing. I also like to use perlite as a rooting medium. Make sure that the container drains properly so that you can keep it watered. You are not rooting IN water, but in perlite.
I always root my coleus cuttings in water and they do well for me.
it seems everyone is able to root coleus in water ... except me, that is ... they rot & get slimey in just a few days ... obviously, doing something wrong?
I left them in the water, the little one has roots as of today. I'm hoping the bigger one will soon!
I have been rooting coleus like crazy...just clip it right below where 2 leaves are ...about a 4-6 inch clipping...then cut off the leaves above where you cut it...then cut off all other leaves except the top 2...now cut the ends off these 2 leaves...can dip them in root tone or not...stick them in some potting soil or Fafards mix...water well & put them in the shade..should be rooted in a few days...good luck!
Coleus is very simple to root. I think using water is over-thinking the process. We just pinch off a piece with our fingers and stick it in dirt ( potting soil ). They don't like full sun for the first couple of days ( they will wilt ) but in about a week they will be kicking it! You can divide these suckers every couple of weeks and get more coleus than you know what to do with.
