Actually, I was following a tip from a friend who said to use 2 liter soda bottles and push them into the soil to water the plant slowly at the roots. It conserves water and keeps things hydrated when you are away.
But wine bottles are cool! Especially the colored ones like blue and green. There are even a few red ones out there. And, they have long necks so they can be shoved down into the soil to remain upright and not falling over in the Oklahoma wind. Maybe I could have at least taken the label off. But, just dig a hole next to your plant the size of your bottle neck, fill the bottle with water and place it in the hole. Water will leak out as needed.
It seems the top flower pot on my “crooked pots on a stick” is always dry. It is small and at the top of the pole so the water runs down into the other pots. So, I thought why not put the wine bottle in the pot to help keep it watered? I also have them in the front yard around a new azalea that I am babying and the front of the bed that gets a lot of sun and is always dry. They are colorful and serve a purpose.
I plan to put the plastic ones around the tomato plants in the back yard. They aren’t as eclectic but they do provide water to thirsty plants in the middle of the summer. My husband mentioned putting a pipe or hose in the hole first that would keep the water bottle from falling over. Good idea.
Try it. Your plants might like it especially with the summer water rationing that is starting up in my hometown.
