Composting tomatoes/cucumbers with diseased leaves?

SunshineZone7(7)August 12, 2014

So happy I found this forum! I need help :)

I know one should not compost diseased tomato plants but how about the tomatoes? Are the tomatoes that come from the plants with say Septoria Leaf spot, are they diseased too? Same for cucumbers with that powdery mildew? Can you compost the cucumbers?

bury them and you will be all right. If possible, in beds that will not get similar plants next year. Not only that, but burying organic matter recovers the most nutrients of any method.

Bury the tomatoes from diseased plants? Where, in the compost? And then you are saying plant different plants in different beds?

If you can be sure the compost will get to and hold temperatures in the 135 to 145 degree range for several days you can compost plants afflicted with Powdery Mildew, because the spores of that disease are killed by those temperatures.
Septoria Leaf spot is spread by spores in the seeds from affected plants, so composting the fruit from affected plants is not a good idea.

I'm a lazy composter, and don't know if I'm going to get a lot of heat, so I have a corner of my 1 1/4 acre plot where I take all of the "not sure" stuff to die!
That would be invasive stuff like morning glory, nasturtium, diseased tomatoes and squash. Anything with disease goes out to the east 40!
The rest that just dies goes into the compost. Nancy
