Garden Coach Answers Reader Question About Amending Soil

Thursday, April 30th, 2009

Moe from Orlando, FL writes:

“I have tomatoes and peppers planted- but the soil is the dark gray sandy type. It gets sooo hot- you can’t even step on it barefoot. What can I use to mulch my plants that will absorb the extra heat, and not take their water?”

Moe, thanks for writing in with your question. You’ve described your soil texture as sandy, which means nutrients and water likely pass through it very rapidly. So, adding a composted organic mulch material will likely help you hold water and nutrients in the soil a little better. Generally, mulched materials are also dark, so they may also absorb heat as well.

Mulch materials should be at least somewhat mixed with the existing soil before planting. This creates a layer of both the existing “native” soil and your organic matter. If you don’t have a mixed layer between the two, you can end up with a situation called “interfacing”. Water has a tendency to not pass readily from one medium (aka a top layer of mulch) into the next layer of soil (aka your dark sandy stuff). By having a mixture of both between, this will help the water pass through. If you do end up with a soil interface, you may have nice moist mulch on top and dried out sandy soil where the plant roots live.

Before you try to start changing your soil, consider ordering a soil test to understand more about your soil’s nutrient information, pH, potential heavy metal content and more. Once you understand this, you will be better armed to make the best choices to adjust your soil for your chosen plants.  Certainly check your local area for labs near you, or consider sending in your samples to the Umass Soil Testing facility.

Good luck!

Composting Food – It’s the Law! A Part of Seattle’s Zero Waste Initiative

Tuesday, January 20th, 2009

There are some big recycling changes happening in Seattle in 2009. Already, styro-coffin take-away food containers are banned. Next up, in April, all food waste, including meat and dairy, will no longer belong in the trash can. Instead, homeowners will be expected to include it in their yard waste pick up. But, what if you don’t subscribe to curbside yard waste?

Well, if you live in an apartment, it appears you won’t be required to compost your food scraps. If you live in a single family residence, you will need to compost your food. New 13-gallon carts for compostables should be delivered to your home by the end of March, and you will be billed for pick up beginning in May.  You do have the option or order a cart larger than the standard 13-gallon size, which will cost you $3.60/month. The largest option is 96 gallons, which will run you $6.90/month.

What if you compost at home? Well, you can opt out of the curbside composting program. But, be aware that by doing so you may get a visit to verify you have a compost system at home!

If you do want a different size container or if you want to opt out of the program, you must notify Seattle Public Utilties of your choice no later than January 31, 2009. The form and additional information is available online here.

Personally, I do it all. I have indoor and outdoor vermicomposting systems as well as a passive leaf clipping composter. As well, I subscribe to curbside yard waste pick up. In our two-person household, we produce more food waste than our worm bins can process. And, our garden produces more clippings than our smallish bin can handle, and honestly, I’d rather use my limited garden space to garden than to put up a huge composting bin system. I have the option; I can pay to have my weeds and other waste taken away for just a few dollars a month. Yes, I end up buying in several yards of finished compost each year, but honestly, I doubt given my space and inputs, I could produce the volume of return material that I need anyway.

Plus, with the city’s recycling program slated to process meat, dairy and fish waste, the price is an even bigger bonus. In vermin-infested city limits where high-heat compost systems are unlikely, processing meat byproducts in compost just isn’t a great idea. I’m sure someone out there is having success, but frankly, for a few extra bucks a month, I’m happy to have the city haul it away for me.

A few questions remain for me about how this system will succeed:

  1. Just how nasty will these bins get, especially in the heat of summer? When food waste goes into plastic garbage bags, it’s fairly well contained. When it goes into an open pile of vegetative rubbish, what kind of nastiness will we be in for — even with 1x/weekly yard waste pick up?
  2. Will rats, crows, seagulls and other critters invade? Sure, they don’t get into the trash cans too often now, but leave the lid off on trash day and watch the party start. If the flip-floppy yardwaste lids remain a bit open from a too-long stick or a bushy pile of grass clippings, will the steak trimmings and moldy cheese bring in the vermin?

What’s next for the zero-waste initiative? Well, if you live in Seattle, you’ll remember all the hype about instituting a fee for having your groceries bagged in a store bag. Well, last I heard this was sent back to the table. Will it be put into play this year? We’ll see. What I have noticed, empirically, is more people using their own bags at the store more often. Good for you Seattle!

Indoor Worm Bin in 30 Minutes

Small, Finished Indoor Worm Bin

Small, Finished Indoor Worm Bin

I’ve maintained an outdoor worm bin like the one mentioned here for several years. This winter, during extended cold snap in December, my worm bin population took a big hit. My need to have some worms and bins for the 2009 Northwest Flower & Garden Show, coupled with my losses in the freeze got me inspired to start a small indoor worm bin. I read a helpful post on Garden Rant recently that gave me the basics to start my indoor bin up yesterday. I borrowed from the plans here, but adjusted them to fit my own needs (and experiences with worm bins).

Not counting the trip to the store to buy the dark tubs, the project took less than an hour to complete. The bins, on sale, cost about $16. The recycled newspaper & junk mail bedding & yard waste leaves were essentially free — and sort of paid me in that I don’t have to pay yard waste or paper recycling to take them away. The grit, leftover from a pathway project, was essentially free. The worms, millipedes and other microbes were harvested from my outdoor bin; I did order a fresh pound of worms as well to boost the population, and they cost about $30 with shipping (they won’t arrive until next week, so we started the party without them). And the food for the worms, well, I figure that’s actually going to pay me. I won’t have to pay trash/recycling fees to take the food scraps away, and I’ll get free compost and worm bin liquid for free to feed my garden.

Please, come on down to my family-oriented worm composting presentation at the 2009 Northwest Flower & Garden Show to get a close-up look at both style of bins and learn more about vermicomposting in your own home or garden. I’ll bring this system along with me to share how far the bin progresses in just over one month!

Have questions about composting with worms or an interest in ordering a worm bin (indoor or outdoor) for yourself? Please get in touch.
