The paper tubes that are left after toilet paper and paper towels are used up are quite useful for the home gardener. I have used them in the past to help mark where I put a seed. The idea is that I will know exactly where to water rather then watering places where there is no seed. In a drought prone area, this can be a good way to save some water.
This year I came up with a new way to use the paper tubes. In the past when I have planted carrots I just spread the seeds and hoped for the best. I sort of tried to put them out well spaced and in a logical pattern, but the seeds typically ended up growing in the low areas. I think this is because carrots need to be surface sown and the seeds would travel with the water. So, this year I cut pieces of the paper tubes and put them into the ground where I wanted the carrot seeds. Then I put a couple of seeds inside of each paper ring. This keeps the seed where it belongs, and it allows me to water the seed better since I know where it is.
So far I am having much better luck with how my carrots are sprouting then in the past. More of the seeds are coming up, and they are better spaced.
I also used some of the tubes when planting other kinds of seeds, but didn’t take any pictures. For instance if I needed to plant a seed an inch or two deep I would dig a hole just a bit deeper then needed. Then I put a section of the paper tube in the hole, put a bit of dirt inside, and placed a seed inside. Then I filled dirt into the tube over the seed. This helps me to get the seed at the proper depth.
I hope this helps you with your planting.
