Class,
Your question for this week is the following:
Now that we have discussed soil amendments like lava sand and mushroom compost, what other conditions are needed for optimal growth of our plants (marigolds and zinnias) in the two flowering beds?
Look on the web or in a garden book about what zinnas and marigolds need to for optimal growth.

research question - Monday april 13
Dear Class,
What other soil amendments can you add other than lava sand?
For example, I saw mushroom compost for sale at Calloways Nursery?

research
I cannot locate the comment I came across earlier about the argument that lava sand has no benefits as a soil amendment.
I have sent an e-mail to Howard Garrett requesting any information on studies pro and con; while we cannot rely on his response completely (because he is very much pro- lava sand, and may be biased), it could be a start to lead us to the research. If research exists, we should go straight to the actual studies to decide for ourselves whether the research is well enough done to be reliable, and to see for ourselves what the results were. Of course, when our experiment is done, we'll have our own results as well!
I'll let you know as soon as he responds. In the meantime, maybe one of you can do a better search than I did. I tried typing in lava sand, controversy, benefits.

Class,
As you know when we checked our two garden plots last Friday, we had one seedling pushing through the lava sand. There were no seedlings yet in the regular bed. We also planted some strawberry plants.
Unfortunately when I looked at the beds this afternoon, the strawberry plants looked rather withered because of the intense winds. Maybe one of you could water the plants. There were also a few seedlings coming up in our lava bed.
We will discuss this in more detail, on Thursday.

Lava Sand
We found out the following about the possibe benefits of lava sand when we researched it.
It lets rain water soak in.
It lets soil nutrients get to the plant roots more easily.
It separates the the clay particles of soil.
It helps conserve water because water is retained by the roots.
Question for this week: Why do some people think lava sand has no benefits?
