Height of sides on raised beds.
Greetings! I am hoping to get a couple raised beds up this year. I want to use 8x8x16" cement blocks for the sides. What do you think will be the best height for the sides of the beds. I am thinking either 24" or 32" due to the size of the blocks being in multiples of 8". I have lost much mobililty and know that a wheel chair is in my future. For now I will still be able to either kneel or sit on a small stool.
I intend to grow mainly peppers, squash, carrots, etc. Probably no corn. The size of the beds I am shooting for is 4'x 20'. Give me your thoughts and or experience. I already use some 5 gallon containers for tomatoes and peppers. Have a great week and a great garden! Jon.
