Moles have been wrecking havoc and creating mounds throughout our small lawn. They turn up the soil and create mounds that will inevitably get sucked into our electric mower as it dulls the blade and creates a bare chunk of grass. The moles like to dine on what’s living underneath the soil such as worms and our soil has a lot of worms! Being in the flood zone along the Russian River, each flood deposits rich soil on our property, long before a house was built on this land.
We decided early on to live with the moles instead of trying to trap them, exterminate them, or buy one of those beeping deterrents off Amazon (they don’t work, for moles or gophers!). Also, because we grow our lawn organically and let the clippings compost, this soil is prime which gave me the idea to grab my shovel. I noticed the soil in these mole mounds was nicely turned, rich, soft and dark. I started to take a shovel to these mounds and deposit these pilings into a large container.
I then built a small sieve out of some leftover 1/4″ hardware cloth and some reclaimed 2x4s. Sifting this soil and adding some vermiculite made for the perfect potting soil and seed starting mix.
You can not buy this quality of soil through a bag at a store. Meanwhile, once the mound is leveled, I reseed the area and wait for the grass to grow back. It seems the moles in our area are more active in the winter. In the summer, when the lawn is used most, we don’t see many if any mole mounds being created.
So, a problem turned into a solution. We now have great potting soil without leaving the house. Often the approach is to get rid of rodents, insects, like the cabbage moth eggs underneath the kale but when we do this, we are not seeing the bigger picture. I can let a few kale leaves have holes to have my other plants have a few extra pollinators (those eggs turn into butterflies). I can let some bad insects live without spraying because I know the predatory insects will begin to show up without the use of pesticides. I can live with moles because we don’t need a perfect lawn and now they’ve become our little soil farmers.
Note: If you want sterilized seed starting mix, try checking out this article on SFgate with some tips. It involves using an oven, steam or a microwave.
Note 2: If you don’t have Moles in your yard turning up your soil, you can use compost you made or soil you know is not contaminated. Sift the soil, add vermiculite and boom!
