I've posted a couple of easy gardening Instructables before. Back in '07 I posted a Soda Bottle seed starting Instructable, the sandwich bag seed starter & propagating succulent cuttings Instructable.
Today I'm posting another easy one that was pretty popular on my urban gardening blog and thought I'd re-shoot some images and make it an Instructable here. You've probably seen empty toilet paper tubes used to start seeds indoors--but I've discovered that they are just as useful outdoors when you are sowing seeds directly into the ground. This method helps me remember what I planted and where and saves on watering.
All you need are some seeds, a pair of scissors, empty toilet paper tubes and a desire to garden. You start by cutting the tube into sections like in the image attached.
Step 1: Placing Seed Markers
If I don't have the original seed packet I will usually just space them about an inch or two apart. Depending on the seed I will usually place two seeds per section in case one dies or gets eaten by garden pests or succumbs to disease.
