About a month ago I split my basil plant in half since I wanted to give some basil to a friend. I had never split a plant before. During the summer and fall months I kept my plants outside on my balcony, but since it has been getting colder I brought it inside about the same time that I split it. I have been noticing that both of my plants are losing lots of their leaves and wilting over and starting to lay down. I placed them in front of my window, but I am not sure how much sun they get since my window faces east and I am gone most of the day. I also am watering my plants about every other day. What am I doing wrong? Is there any hope in saving my poor plants?
You can't actually "split" a basil plant as they grow from one stem. What you probably had is a pot of seedlings / small plants like they are sold in grocery stores or garden centers for cooking. Please see this post for more details.
As for the collapsing, I see a few potential causes, but without pictures it is almost impossible to say for sure what causes it:
- frost / cold temperatures
Are you sure they weren't exposed to frost? But this usually finishes them off rather quickly.
meaning lanky growth due to lack of light, eventually toppling over
- some fungus (check the stems, basil can be susceptible) or pests (check the underside of the leaves)
- and finally: The end of the life-cycle.
Basil is an annual which will die after flowering/seeding.
