My biggest concern with my tomatoes in the spring is WIND protection. Most of my tomato fatality's are caused by the wind. A sustained wind of just a few miles per hour can murder your young tomato plants very quickly.
A whole host of problems are out there in the spring to kill your plants from late frosts to insects here is a suggestion for my biggest problem the wind.
This is just some cages we make out of wire we wrap a layer of fabric around the cages. This fabric is a weed barrier we purchased at home depot. We like it because it breaths well so it doesn't get to hot. All were doing here is wrapping the weed barrier around the wire taping it on and were done. So easy so simple.
In just a few weeks we will take this fabric off and let the plants go. Young tomato plants need protection from the wind for at least 3 to 4 weeks. You will have better earlier tomatoes enjoy.... Later dusty
