Last year, I used soaker hoses then tore them out because they didn't water very evenly. I used a hose, with no attachments and the water only half-way on, and watered the based of each plant. I had to water 2-3 times a day because I had no mulch, high heat, and sandy soil. This year I've mulch and am watering the base of each plant once a day. I don't water overhead, unless it's freshly planted seeds
, even then, as soon as I see green, I stop.
I've got some tree roots in my garden, we yank them out every spring
and they quickly grow back. They make life miserable, don't they?
