I have a water hose on a hand reel cart. I don't move the cart - but it does make it easy to pull the hose out and gather it back neatly and quickly.
I use a cheap $3 watering wand on the "shower" setting using it at about 1/3 pressure; never full as that "blasts" the soil around and causes unnecessary splash back.
Slow and steady. It takes me about 1-1:30 hour(s), 2x a day to water the garden when having high temperatures.
The soil was designed to drain well but also hold a lot of water. It's some what necessary with the type of weather we get. High heat with no rain, then monsoon for a day or two, then high heat with high humidity and no rain. Repeat.
If the soil doesn't drain well, the heavy rains will flood everything out. If it doesn't retain water then the high heat and 3 week droughts will certainly dry everything up.
Thank you for the kind words! It's encouraging!!
