I'm worried also about the days cooling a bit and getting shorter in regards to our tomatoes. Most of the first crop of them have been pilfered by deer. I've come up with a possible deterrent that's worked for a few days.
If this works out, the plants could give us a late crop, as they are still blooming, and haven't been totally disabled by deer munching and diseases. But, I'm wondering if their production might be hampered by the cooler weather, provided they can escape any more deer shenanigans.
