I use the plastic Haws for fertilizing (1 gal) so I never ran it to that problem. I had a 1/2 gal previously for the task, too much work. For hand watering I use a watering wand.
A word of caution do not leave your plastic Haws outside exposed to the sun. UV and pastics do not mix.
Time for the monkey wrench :D:D
That is why fertilization, "proper fertilization" at the "proper time" with "the proper fertilizer" will pay large dividends.
