At a garden meeting some months ago, our speaker was Robert Bowden -- chief honcho at Leu Botanical Gardens in Orlando.
He mentioned that a lot of the basil plants may start out OK, but soon the leaves droop, turn yellow and just look awful. Well, it surprised me -- a lot of the plants are actually grown in Asia and shipped here -- and they had a virus. I had one that look terrible so threw it out. However, I also had a large basil plant that was over a year old and I allowed it to go to seed. I used those seeds and now have some gorgeous, healthy plants. I'm potting some up to take to our first garden club meeting next month.
