Potatoes and Tomatoes

Pay attention to the yellowing of the bottom leaves of your tomatoes and potatoes. SO far this season has been warm and rainy and the blight loves that type of weather.  Yesterday, I was looking over my potatoes and they seem to have it, so I cut the plant down to the soil line.  Potatoes are know for keeping sprouting, so I hope they keep growing.  I happened to check on the tomatoes, and since this year I plant them too close, then they could also get fungal diseases.  I picked the bottom leaves, since they had yellow  and brown spots (not a good sign at all).  I also stopped watering, since it doesn't help with the humidity and hot weather this season.  My advice is to keep an eye on your tomatoes and potatoes this season. 
Also, garlic is about to be picked, since almost 5 leaves are dead on each plant !
