The raised bed garden I built between yesterday and today for Irene.
along with her cat and dog helpers :)
It is 16 standard cement blocks, and about 12 bags of different soils, a third of which is 'container gardening mix' We lined the bottom of the area with cardboard before we put the soil on top, just like I did in my own raised bed garden three years ago. The next step is to water it down good, and let it drain a little, and plant a few test quick-germinate things to make sure the ph level is good.
Radishes like pH of 4 to 5. If they come up purple instead of green - it is WAY too 'hot' of soil. Komatsuna and mustard greens like 5 to 6 pH, and cabbage likes 6 to 7. All of these things should show 'signs of life' within 3 to 6 days if the soil mixture is good. If it is, then put the greenhouse plants in it. If you see any warning signs, get a pH kit or, in the case of knowing that it is 'hot' - add pelletized lime, water down and let drain again before trying again.
