Our new front yard, part 3: design

...sely planted from above, but if you get down on your knees and look at the soil at ground level, there may be all sorts of bare soil between the plants. To avoid this, you plant in layers, from the ground up. They identify four types of functions for plants in your design: Ground cover plants: They emphasize the importance of ground cover plants as the base layer of the community. These are low, somewhat nondescript, spreading, shade tolerant plan...

Watering 101

...out. There is no formula. In the picture above, you see the surface of the soil in one of our raised beds. This is imported soil, the kind that comes in bags. It doesn’t hold water in pools like clay soil does, it doesn’t sink in fast as it would in sandy soil. It’s actually pretty tricky to water because it seems like it should sop up water well, but I think all the organic matter in it actually slows absorption. At any rate, I’d been watering th...

Day to day, our decisions count

...licking on the tag to your left] *** Last week I introduced the subject of soil. Healthy soil is fundamental to a the loving landscape, to healthy people, to a healthy world.

Gardening Mistakes: Six Ways We’ve Killed Plants

...ertility When it comes to growing vegetables, in particular, you need rich soil. Get a soil test first. But soil fertility is a lot more than chemistry–it’s about life.

I’ve bought my share of root bound plants and plants that came with diseases. The worst example I’ve...

Best Practices for Gardening in Contaminated Soil

...will improve soils in urban areas, resulting in reduced bioavailability of soil Pb and reduced fugitive dust. Plant uptake of Pb is also typically very low. The exceptions are low-growing leafy crops where soil-splash particle contamination is more likely and expaneded hypocotyl root vegetalbes (e.g. carrot). However even with higher bioaccumulation factors, it is not clear that the Pb in root vegetables or any other crop will be absorbed after ea...
