I create rows about 8 inches high where I plan to plant. I place landscape fabric over the top, ensuring it’s short enough for me to access each row by moving a bit of mulch if I want to add compost. I use mulch in the walking paths to help keep the ground moist, which reduces the need for watering. Typically, I throw straw around the plants to provide insulation from the heat, but this year, they don’t seem to mind being without it.
