This is my 4x4' planter box. I planted all of this around two weeks ago. To the left is African Hibiscus, Gazania and pansies. To the right is Southern collard greens and Italian Parsley. And that big heaping pile of tortoise food in the middle is summer squash. It grew huge really fast. I have been trimming leaves off daily because it is shading all the other emerging plants that I planted too close to it.
So the lessons are: 1. Don't plant anything within about three feet of a squash plant.
2. This stuff will make excellent food, shade and cover in a baby pen. They can get under this canopy and feel totally safe and shaded from the sun, and then have a snack at will.
