When To Start Seeds Indoors For Spring Planting

Starting your own plants from seed is truly an exciting gardening project. There is nothing like the satisfaction of eating a ripe red tomato on a warm summer afternoon that you have started from a mere seed several months before indoors. Yes it may be a little more work than just going to the nursery to choose from all those rows of plants brought in by the truck load but there are many benefits. Starting seeds indoors is a great way to get the jump on spring. It is also a way to get established plant varieties not grown commercially such as heirlooms .

  1. Just wanted to make sure you saw this opinion-editorial I co-wrote with Urban Harvest for yesterdays Omaha World-Herald about urban and vertical gardening in the heart of Africa’s large slum Kibera in Nairobi, Kenya. Here is the link, post to our blog at the Worldwatch Institute called “Nourishing the Planet”: http://blogs.worldwatch.org/nourishingtheplanet/omaha-world-herald-kenyan-farmers-persevere-despite-cultivation-challenges/

    All the best, Danielle Nierenberg (www.borderjumpers.org)
