basil bugs and moreIt's impossible to exactly explain the failure of your basil plants to thrive. Like so many plants, this too can be tricky. It can be vulnerable to downy mildew and there is nothing you can do about it. It can be brought in on transplants, in infected seed, or as airborne spores. The best thing you can do it try again. Use good composted soil, wet but don't drown the plants, give them adequate sun. And it could be something else, too. It's tragic, but better luck next time.
