DIY Tip of the Week: Organic Potting Soil
Posted on: April 5, 20103 comments so far (is that a lot?)
Spring is here and it is time to plant your garden. Temperatures are right, the sun is out, and everything is starting to bloom. With sporadic April showers, nature will provide some free watering to those freshly planted seeds and seedlings so get out there and start your garden. Not only will you be so excited to see your plants grow, but when you get a taste of the freshest fruits and vegetables, you will never be able to go back to the store again!
Here are a few recipes for great organic potting soil to get a jump start on that garden. If you truly want an organic soil, make sure you check everything that you put into your mix. Don’t rely on anything being pure. Do a bit of research. You’d be surprised what you’ll find out there that has been treated.
Make sure you plants are getting sun, water, and air!

Thanks Cy, Rebecca is planning on planting an all Organic Garden this summer on the side of the house. Being all raw, it’s getting harder and harder to afford all the organic fruits and veges. G

Great stuff! In the uk we have a big problem with the use of peat as it is taken from fragile wetland ecosystems. For a good rich blast of nutrience It’s worth seeing if there are stables near you. Through the winter they’ll have tonnes of manure they want shot of so it’s usually free and if you put it out into your beds on a clear day in the winter then the frost, rain and crappy weather breaks it all down so that it’s good rich earth by the time you actually want to go out and plant without having to raise a finger!!

I’ve been composting for the couple of years or so.
Stoked to not have to send all that foliage to the land fill and to be able to recycle it back into the garden.
EZ to do and if more people did so it would have a large effect. Great tip!
