Each year that you tend your garden lot it is going to get better and grow better fruits and vegetables.
Each year you are adding more compost and nutrients. You are removing weeds and plants that are getting in your way.
Think back to how things grew last year if possible. Change things that didn't work, and stick with what did work.
Weeds compete with your plants for water and nutrients. Getting rid of them before they have a chance to take over your garden is great, but having a plan to prevent them from growing is best.
Add some compost. Compost is full of nutrients that will help your plants grow strong and healthy.
