I have two high tunnel gardens. Last year I planted plum tomatoes and Big Boy tomatoes for fresh eating. Also planted Bell and bannana peppers. Beans and butternut squash grows up on chicken wire panels . Spinach , kale and swiss chard also.
Carrots in a raised bed and a few leeks there too.
I had failures with cantolopes and watermelons. Lopes were small and rotted before getting to any size. Watermelon plants looked great and had an abundunce of flowers, All the flowers were male until October. You only get fruit on female flowers. The few female flowers that I got melons on came too late in the season. First frost and they were done.
I am trying lima beans for the first time. These will grow on eight foot high frames lined with chicken wire. I have about 20 lf of these frames.
I do not have a pest problem anymore. I tried to get rid of white flies with lady bugs , green lacewings and then chemicals. Lacewings did work for a while. Lady bugs were a waste of money as they dissapeared in two days. Chemicals worked but not very well.
I was told about Neem Oil. Tried it and was pleasantly surprised.
Kept all whiteflies , aphids and other insects out of the gardens.
Also found that Neem Oil works as a fungicide.
If you use Neem Oil read the directions carefully. Only spray when the sun goes down, otherwise the plants will wither and die. Make sure the mix is exactly as noted. Too strong a mix and the plants will die. Often the oil will solidifly. Set the container in a pot of hot water, not boiling. The oil will return to a liquid.
I had rocks and tap roots in the way when I first planted these gardens 39+ years ago. Probably spent 40 hours removing tap roots , raking rocks and removing a small area of marl ( clay).
Still finding a few rocks every year.
We had a groundhog problem, solution was a 177 caliber pellet rifle. Had to hide the critters as the wife thinks their cute. These "cute" critters can destroy a garden in a few hours.
