My dad was a master gardner.
He had a huge garden with all types of plants. I hated working in the garden as it made my skin itch. It was a lot of work. He had 60 tomato plants in the ground and staked up when he had his stroke. The garden died that year. The only thing we have left is one blueberry bush. I picked all the blueberries I could get and have them in the deep freezer now. We had a 26 cubic foot deep freezer, and it was packed full of vegetables when dad was still around. He grew tomatoes the size of softballs. Early Girls, Big Boy's, and Celebrity. Green Beans, Pea, Sweet Corn, Carrots, Radishes, Lettuce, Squash, Strawberries, Lima Beans, turnips, apples, raspberries, grapes, Boysenberries, and at least 12 Blueberry plants that didn't make it. Only one big blueberry bush survived. Oh yea. He planted some Pear trees too.
He watered the garden during the sizzling summer months when it failed to rain. He watered in the morning so that the water would soak down to the roots before the sun got up too high in the sky. If you water in the evening fungus will start and kill the plants.
I will share one thing that he taught me about gardening. Phosphate Rock. We used to drive 50 miles to Owensboro, KY to buy bags of phosphate rock. He also would have horse manure delivered and spread on the garden every year and tilled that into the soil.
One more tip. He used diatomaceous earth to kill bugs. He would also buy praying mantis eggs and put them into the garden to hatch. They kill a lot of harmful bugs. And he would use Seven Dust at times.
From what I learned watching him was that Soil preparation was key to a good garden. And don't overwater the tomatoes as that will make them split. Use mulch around the plants to keep the soil from drying out.
Note: Limiting nutrients like Phosphorus, and Potassium are needed for plant growth and blooms. He would make me mad when he used RAID on the young plants to keep the rabbits from eating them. And watch out for the ground hogs as they will eat the young plants as they first come up out of the ground.
Before my health went south, I would grow tomatoes, squash, and cucumbers in my small garden. My dad used one-third of an acre to grow his garden and I only had a 20 ft by 12 ft patch of dirt. My soil was full of clay and his was more organic with all the horse manure he put into the soil over 35 years. We would drive out to the East Side of Evansville on North Green River Road to a veterinary office where the vet kept horses and shoveled horse manure into the back of his 1/2-ton pickup truck and take it to his garden and spread it out into the soil. Then he had a horse farmer who had aged horse manure mixed into saw dust and had that farmer deliver it to his garden and store it in big piles. Dad would let it age before putting it into the soil. Amending the soil is a key to a good garden. The horse farm was up in Warrick County, IN. His father had a big garden too. I remember as a child walking through my dad's father's garden and catching toads. ha ha. And the toads eat a lot of harmful insects too so let them live in the garden.
