Each morning and night, I water them from plastic watering buckets. The one planter, however, is up on my front porch, a bit away from the back driveway where the cukes are. I've been trying to water that one from Big Gulp plastic cups. I don't want to bring a big watering bucket around each day. But I couldn't think of another solution.
Eureka! Today, I happened to realize that I have nice handy watering jugs sitting in my pantry. I thoroughly rinsed out a plastic Clorox jug that was almost in the air, being ready to toss to the recycle bin. I rinsed it over and over to make sure all the bleach was out of it. It is just perfect and even holds enough for two soakings, one day's worth.
Here is what I've noticed after taking a quick visual tour of my pantry and kitchen, regarding re-purposing jugs for watering use.
bleach, large syrup, large vinegar, liquid detergent
milk - these tend to be too flimsy - I'd want a jug to last a few months or even a year or two
Gee - I am SO proud of me!!!!!
