I planted butternut squashes on the north side of the tomato cages.  That way they don't shade the tomatoes, and they can climb the cages, keeping the squashes off the ground.  I get a lot of mileage out of the sunny spots in the garden.  

 

Some plants will do ok with some shade, but tomatoes, peppers, and eggplants want 6-8 hours of sunlight a day.  They get the prime real estate.  Squashes and beans and green leafy vegetables like a little shade, so we create it for them by planting them on the north side of the tomatoes.  

 

So far, everybody seems happy in my garden.  Even the weeds are smiling. 

 

HAPPY GARDENING!!!
