Check ’tilth’ in organic garden for soil moisture
I guess weird weather is the “new normal” now, with weeks of no rain, crops fried in 100-degree days, then rain falling finally, blessedly, but perhaps too little too late for many this season.
Given the heat, now’s a good time to check the moisture holding capacity of your soil. If you have adequate tilth (loamy material) and regular watering, you should have only a light crust on the top but can push in your finger without a great deal of effort.
But if it’s too hard for a gentle push of the finger, don’t despair. It can take years to build up the soil. We’ve dumped tons, literally, on our plots and they break down rapidly with acidic, sandy soil.

Remember, with organic gardening, the soil is everything, but it’s a moving target. It’s a constant balancing act between biomass and soil digestion activity.
Take this as an opportunity for future growth: Just keep adding more compost and, in fall, more leaves or other vegetative matter to build up your tilth.
By the way, old folks used to put sawdust in their gardens. That’s fallen out of fashion, as it tends to eat up nitrogen breaking down. But if you are using foliar feeding – spraying kelp or fish emulsion to feed nitrogen for it to be absorbed through leaves – I believe sawdust could help hold soil moisture. That is, as long as it’s not chemically treated wood.
It was good enough for our Mississippi forebears and Helen and Scott Nearing – homesteaders in 1930s Maine (see their book: Living The Good Life). So, if you’ve got it, I’d use it.

Growing tip: You can grow your own natural sweetener using leaves from the Stevia plant. It’s not too late to plant to get some leaves by fall.
According to WebMD, it is useful for those who suffer from obesity, type 2 diabetes, heart disease, metabolic syndrome and other weight-related medical problems.
The leaves contain the sweet glycosides stevioside and rebaudioside, which are 300 times sweeter than sucrose (table sugar). Seeds are commonly available and can be purchased from Burpee, if not locally. It grows prolifically, like mint.
We grow it and use it. Tastes great. I like it in my tea instead of sugar.

Summer reading: I recommend: Fair Food: Growing a Healthy, Sustainable Food System for All by Oran B. Hesterman (PublicAffairs, $24.99).
Founder and head of the nonprofit Fair Food Network and a former agronomy professor at Michigan State University, Hesterman is quick to point out that he is not writing about our broken food system from the standpoint of a chef or journalist, but as someone who has experienced it from plow to plate.

The observations he makes are similar to the popular notions of journalist Michael Pollan and chef Mark Bittman, but his methods are more direct, from developing locally profitable food distribution systems in urban and rural “food deserts” to joining corporations such as Costco in developing transnational fair trade supply trains that ensure living wages for producers and reinvestment in local communities.
Fair Food is a serious book about a serious subject. It offers ideas for local communities, as well as suggestions for local, state and national policy makers (I hope members of the Legislature read this book!) It should add immeasurably to the national conversation about fixing our food – and world! – for the better.
