Basil can grow up to quite tall but it needs to be harvested regularly, otherwise it will start to flower and then die. I try to keep mine growing for as long as possible by cutting long stalks and replant them.
It's really pretty easy. All I do is pluck off all the leaves (for cooking or drying purposes) at the bottom, leaving top most 2 or 4 leaves of each stalk, then place them into a glass of fresh water. Over the period of a week or 2, they will start to root. Once the roots are about 2" long, I will transfer them into soil.
I also do the same when the bottom of the basil plant start to turn woody. This would be the time I prune it all down, root the upper part that is fresh and green, and uproot the woody part to refresh the soil to be ready for new plants.
This is what I often get left with, and I'm certainly not going to let them go to waste.
So I'm going to have a big melt down - for the wax 😀
It's not a very complicated process, just a little tedious and hot.
What I need are:
A big pot
Some used disposable chopsticks
Some parcel string (as I haven't any wicks readily at home)
Glass containers/candle holders - to clean up glass candle holders: boiling hot water
is to melt the old wax (different colours separately) in hot water in
the pot, with the string tied to the chopstick placed over the glass
container. The string can be fiddly. To make it easier to work with I'll
dip it with some melted wax then straighten it whilst the wax dries and
hardens up. That way it will stay down to the bottom.
