Although we don't often talk about soda bottles helping the environment — usually they're doing the opposite — that's exactly what they're doing here. There are still some chilly nights around the country and small annuals can be at risk for frost. Worry no longer with this simple trick.
By simply removing the top of a soda bottle and placing it over the soil you're helping your small tender plants to retain precious humidity and warmth. You don't have to worry about messy bags or tenting them with plastic. This quick trick is a simple fix and best of all, you can always use the tops later for funnels if you so desire!
