The basil leaves are now growing as usual, producing yumminess for our dishes. However, their stems appear permanently damaged.
They are hard and brown like sticks. I considered starting from scratch; I could buy another sac of seeds. But these basils had been good to me before I left them, rich with flavor. Rather than start from seed, I decided to propagate from the plants I already have. It’s a win-win for all of us: the plants pass on their genetics, and I get more basil for free.
It’s a very simple, but fruitful procedure.
How To Propagate Basil from an Adult Plant
First, snip a lush piece of the plant off. Make sure the piece has at least four or five big green leaves that can absorb sunlight well. Also, remember to leave leaves on the original plant too (otherwise it can’t absorb light).
Place the bit you’ve snipped into a cup or jar or test tube or whatever container you have available full of fresh water (it should be see-through so you can keep an eye on developing roots). Don’t let any of the leaves get wet. The leaves must stay out of the water, while the stem must be submerged.
Switch the water every two days. The water must appear clear and oxygenated–this is why it must be changed a lot.
After about a week, you will begin to see the start of roots growing from the stem. Allow these roots to grow for a few weeks.
Once the roots have grown over 2 inches long, you can pot your brand new basil plant!
