Spacing and Planning

Tomatoes: Tomatoes need approximately 2 feet in between each plant. This is for staked tomato plants which is the way I think I am going to grow my tomatoes. Tomatoes like warmer temperatures, so I will plant them on the sunny half of the garden.

Zucchini: One healthy plant about two feet apart. Zucchini like moderate temperatures, so for spacing purposes they will go on the shady half.

Cucumber: One plant every 12 inches. Cucumbers like to be warm and will be on the sunny half.

Peppers: One plant 18 to 24 inches apart. Peppers will not fruit if it is too hot, so I will plant the on the shady half.

Spinach: Spinach plants can be within a couple inches of each other. It also makes harvesting easier when they are closer.

Lettuce: Seedlings can be planted about 4 inches apart.

After looking at these spacing needs I think I am going to plant my seeds long ways, rather than the original idea of planting them perpendicular to the fence. I will post a picture of my new plan soon. I am going to plant the spinach and lettuce at the very end, perpendicular to the rest of the garden. The fence makes a corner and more shade at the end. Spinach and Lettuce like cooler temperatures and will do better mostly out of the sun.
