It seems like summer came a month early. Each of my hanging baskets is drying out faster each day. It got to where I was watering them three times a day and they were still drying out terribly.
I supposed it had been a bad idea to plant the cucumber in one of the hanging baskets and transfered them to a large bowl planter. As for the pea vines and the morning glorys, which had twined themselve about everything, transplanting was not an option. Those liners hold dirt well enough but they do NOT hold water, in fact, they are so porous that the dirt may as well be spread out in the hot sun. I had to find some way to keep the water in the baskets.
My First Solution: Soil Moist Water Crystals:
My Logic: These crystals absorb extra water and holds it until the external environment starts to dry, then they release the water.
My Process: Yeah, the instructions say, for existing plantings, to poke a hole and put the crystals down inside, cover with dirt, then water. What resulted was a beautiful (slow motion) guyser of water crystals rising out of the dirt like gelatinous zombies.
Conclusion: I will stick to mixing the crystals in with the fill dirt.
My Second Solution: Waxed Paper.
My Logic: If I wrap the inside (or outside) of the basket with waxed paper then the water will at least pool in the bottom for a while before the paper becomes saturated and evaporation starts. (Usually the water runs right out of the bottom almost as soon as I start watering.)
My Process: Bowl 1: It is not a hanging basket but a small bowl planter with some flowers that dry out too quickly. I upturned the plants and soil, and put a large strip of waxed paper in the bottom, then dumped the soil and plants right back in. Because the roots weren't much disturbed it fit back in perfectly.

Basket 1: This is the basket from which I transplanted the cucumber. It was empty and I lined the liner with a large strip of paper, cut off just below the top edge. Of course it was folded in on itself a bit to conform to the bowl shape. I then filled the basket with a pre-moisten soil mix.

Basket 2: This is a small basket occupied by several pea vines and morning glorys. Thus occupied I was only able to lift the contents a few inches without possibly damaging the vines. With this basket, I decided to put the paper underneath, between the coco liner and the metal mesh. Since this basket was much smaller, I was able to have the paper more than halfway high all around.
Watering the plants was a pleasing experience since the water wasn't pouring out the bottoms. The next day the soil still felt moist. This seemed to work well for a few days. Then i noticed that the Bowl 1 seemed too dry despite a recent watering. I watered again and noticed water pouring from the bottom. Turning the plants out, it seems that my neighborhood pests decided to chew holes into the waxed paper
That defeated Bowl 1 experiment.
The next day, while watering Basket 2 the same thing occured. I checked and checked and could not see any discernable holes. When I lifted the paper coated liner, I realized that the wire had bitten into the paper and scored a line from top to bottom. Basket 2 has been defeated.
The only one holding it's ground, was hanging Basket 1. It seems to be consistenly moist and the seedlings I put there are thriving. I've not had to drench it with water, just a light sprinkle in the morning. It seems that putting the waxed paper within the lining protects it from being eaten or worn into. I think the only thing that may foil the paper (sorry I had to say that) might be the roots of the plants trying to grow beyond the paper and tearing from the inside.
My Conclusion: I am pleased with the outcome of this experience and intend to try this process with my other shallow bowls and planters as I replant. My Urns are notorious for drying out and this waxed paper lining may benefit them and prevent me from having to water them so often. Of course I will give an update on how the paper solution holds up.
Have a Happy Thursday!
