How do keep those rows weed free?
MOD
Don't water walk area between rows weed seeds don't grow. Boards around beds are levees to hold in water. I have no raised beds. Tomatoes & Peppers have soil pushed up in an irrigation row like a levee both sides of the plants. Fill the levees with water not the walk areas. Once a week I look for weeds to kill with the hoe or rake. It took me 50 years to learn how to NOT grow a garden. Look at the photo. See soil in 2 parallel rows to hold water for the tomato row. If we get too much rain soil is washed away then I use a rake to push soil up like a levee again. 2 parallel levees hold in water. I do the same thing for, peppers, melons, herbs, celery, beans, corn, etc.
Potatoes are 3 rows of seed potatoes in a bed with levee. Left of potatoes are 7 rows of onions & garlic in a bed. Left of onions are 7 rows of strawberries in a bed.
Last picture see how every row has 2 soil levees to hold in water for that row. 20 watermelons & cantaloupe have a levee to hold in water & 4 ft of space both sides for vines to grow. Rake melons in a clock wise circle when vines get too long cut off the ends.
4 rows of G-90 sweet corn on the far left side are not planted yet.
I can remove the boards at both ends of the beds to till soil in the beds. I usually fill beds with dry dead tree leaves then till them into the soil with fertilizer. Each plant has its own fertilizer that it likes best.
