Grow the Soil

Above, proof of the adage that you grow the soil not the plants. On the left a vigorous eggplant growing in high-end potting soil in a self-watering container. On the right a spindly, nitrogen starved specimen of the same variety of eggplant, planted at the same time, in our parkway garden. The container eggplant on the left is larger, has greener leaves and is obviously more healthy. The stunted eggplant on the right is the victim of depleted s...

The Homegrown Mailbox: How and Where Do I Get My Soil Tested?

...tifyin’ and make no claims to accuracy. But, we’re happy to take the letters from Kevin, the horse poop for compost and try our best. Here’s one question we get a lot: Q: Y’all know where I can get my soil tested? I’ve started HUGE garden in my side yard and it just occurred to me that it is where people used to park their cars. I’m concerned about Oil or other pollutants from the cars that might still be in t...

Five Lessons We Learned About Lead in Soil

As regular followers of this blog may recall, we did some soil tests last year that revealed elevated levels of lead and zinc in our backyard. The cause? Most likely, paint from our 92 year old house and nearly a hundred years of auto exhaust and dust from brake linings. Applying a little alchemy to turn lead to gold, I think the most productive thing I can do is to help get the word out about lead soil and how common this problem is in urban a...

UMass Soil Testing

I finally got around to trying out the University of Massachusetts’ soil testing service and can report that it’s fast and cheap. I tested two areas of my yard for both nutrients and heavy metals and found out, more or less, what I expected, that I need to add a small amount of nitrogen. Surprisingly, for having such an old house, I don’t have a lead problem. It costs just $9 for the basic test and $13 for the basic test + hea...

Till vs. No-Till

...na mulch and the pros and cons of double digging/tilling. Let’s address them in separate blog posts, beginning here with double digging/tilling. There are some very persuasive arguments in favor of a no-till, leave the soil alone approach. Chalker-Scott in the comments section of her post on lasagna gardening says, . . . double digging (the equivalent of tilling in agriculture) disrupts natural soil building. No-till agriculture is incre...

Healing the yard with a huge compost pile

The new compost pile is covered with a tarp to keep moisture in. Eventually it will fill this whole space. In the background you can see our leftover adobe bricks. So–our regular readers will know that we have high levels of lead in our back yard soil. We’re dealing with this by filling most of our yard with mulch and perennial natives to lock down the soil (lead laden dust is bad) and to diversify the local ecosystem. Mea...

A Cheap Soil Testing Service

I’ve started a new method in the garden: test the soil, amend according to the recommendations and grow. Lather, rinse, repeat. In many parts of the U.S., you can get free or low cost soil tests from your county extension service, but not here in Los Angeles. Some time ago I answered a reader’s question about where to get soil testing done, only to have to correct my response several times. Last week, Homegrown Evolution pal and the...

Get a Soil Test!

Regular readers have probably already got this message, but right now we can’t repeat it enough. If there’s a lesson with our backyard lead scare , it’s to practice due diligence when beginning a garden –or better yet, when you buy property–and that means getting a soil test from a soil lab. They’re not that expensive, especially when you consider the high cost of remediation, and the well being of your self...

Remember to Label Those Jars!

Label, label, label!” This was one of the most important lessons I learned in my Master Food Preserver training. You’ll note, from the jars above, that I’m not very good about this. When were those jars canned and what’s in them? I have no idea. They were probably the result of some late night canning frenzy two years ago. At the time I probably thought to myself, “I’ll label them in the morning.”...

Peat-free Planting Mix Recipe With Coconut Coir

...ss which, upon being subjected to extremely high temperatures (850C +), puffs–sort of like popcorn, or a Pop Rock. Obviously, though its origins are natural, it is an industrial product, but it is very useful for making soil fluffy and light. You will recognize it as the “white stuff” that you see in the soil of nursery plants. As it is essentially a rock, it is a neutral player in the mix. It simply keeps things light. Note: yo...
