K. Pinnatum is a really cool succulent that propagates readily through stem and leaf cuttings. Considering it’s medcinal properties, I’m sure many of you would want to propagate this plant and share with friends.
Propagation through stem cuttings:
1. Take a healthy green 3-5 inch stem cutting from the plant and remove all the leaves from the bottom 1 inch. Save those leaves for later.
2. Make a slant cut with a sharp blade at the cut part. Your plant will still root if you skip this.
3. Dip the lower 1/2 inch of cutting in rooting compound. (Again optional. I’ve rooted many cuttings from this plant with 100% success without the rooting compound)
4. Insert the cutting in a well drained potting medium.
5. Water the around the cutting not directly near it to prevent the rooting compound from washing away.
6. Cover the pot and the container with a transparent plastic cover. (Can be a polybag, saran wrap, or anything) (Again Optional)
7. If the cover is airtight, poke a few holes in it for ventilation.
8. And wait while keeping the medium moist.
Propagation through Leaf Cuttings:
1. Pluck a few health green leaves from the plant or use the ones you removed for stem cuttings.
2. Lay the leaves horizontally over well drained potting mix preferably in a shallow tray.
3. Water the medium till it’s moist.
4. Cover the tray with a transparent plastic wrap. (Important for faster propagation)
5. Wait for upto a month and keep the medium moist till then.
Keep all cuttings in bright indirect sunlight and protected from hot or cool drafts of air.
Rooting medium depends upon availablilty of materials where you live. You can use a commercial potting mix but make sure it has no added chemical fertilizers. I use cocopeat / cococoir along with garden soil in a 70-30 percent composition. I wish I had more resources in my hostel but most cuttings root in this medium. Choose something that is not compact, airy, light, absorbs water but drains well all the excess water. A way to check is take some in you fist and sqeeze hard. If more than a few drops fall, you need to alter the consistency. Always tend towards a sterile medium as they reduce the chances of rot.
Watering scheme varies according to size of your containers. Smaller containers will dry out faster and will need more frequent watering. I cover my cuttings with a polybag so I have to water less and it also provides some humidity to the plants to minimize water loss.
Plants need some humidity to survive the rooting process. Although this plant won’t need it, I still use a cover. If the plants appear to be rotting, maybe humidity is high. Poke a few holes. If the leaves are shriveling, water and add a less ventilated cover.
