I have been gardening off and on for the last 20 years but feel I have so much more to learn. Over the last few years I have been trying very hard to do some organic gardening but seem to lose so many vegetables to disease and deer every summer that I feel discouraged. I would love some suggestions on keeping deer out. We have a fence which they just jump. Then we put up a second higher wire of fishing line which worker for a short time. The deer cleaned out the tops of my sweet potatoes, ate my green beans and my tomato plants too. Feeling discouraged. Also I seem to lose my squash and cucumbers every season due to that moldy disease. I switch planting spots every year but only get to harvert a few before my vines start to wither and die. I hate to spray them. Any ideas?
