Compost can really benefit the plant in numerous ways, make sure to present it to the plant often and don’t worry about fertilizing the plant, if you want to do so, then make sure to do it at the beginning of the spring. Make sure to trim off woody parts after a few seasons to make it grow better.
Make sure not to remove the spikes before the plant starts flowering because the flowers will send signals to the plant to slow down flower production because it thinks that it met season goals. You don’t want to do that, you want to trick the plant to produce as many flowers as it can before it flowers to have a good harvesting experience.
