There are many ways to raise worms and there are a lot of great ideas out there. Over the years we have posted pics of our bins and beds and some of our friends have shared theirs as well. Send us pics of your worm bin. Your idea might be the one to help someone get started or improve their set up. kyleharrell@hotmail.com
Soil remediation with Earthworms
25 JunGroups collaborate in India to clean up toxic land with earthworms.
4 acres of contaminated soil in India where 300K earthworms were added. After one year there was a 60% reduction in heavy metals.
What type of worm is right for you?
10 OctEarthworms have a couple of jobs, and depending on your goals you will need to decide what worm is best for you. Earthworms feed on decaying organic matter and produce castings. Worm castings (worm poop) is nitrogen rich, pH balanced, humous that is ready to be absorbed by plants roots immediately. Earthworms are the intestines of the soil and are top soil producers. Beyond soil production, their other job is to tunnel through the ground aerating and mixing the soil as they work. Earthworms are also the “plow of the soil” mixing layers of earth while they eat, tunnel, and deposit their castings. These tunnels allow oxygen and water to reach roots of plants and break up compacted soil for greater root penetration and growth.
Red Worms (eisenia foteida) If your goal is composting and worm casting production, this prolific producer is your worm. Well suited for bin raising, not a candidate for adding directly to soil.
European Nightcrawler (eisenia hortensis) Larger worm that is an excellent for composting and fishing. Well suited for bin raising, not a candidate for adding directly to soil.
Alabama Jumper (amynthas gracilis) Large worm that is a powerful aerator. Strong worm that is ideal for adding to garden or soil and can burrow deep in hard packed soil. These worms are deep divers and do a great job of mixing layers of the soil, can be bin raised but are better suited for the soil.
Flow Through Worm Bin part 1
22 MarI have tried several models of flow through systems and continue to tinker to get the results I’m looking for. The idea is for the finished castings to fall through the grate at the bottom of the bin and the worms to work towards the top of the bin.
Materials: square metal tubing, plywood, braided cable, 1.5″ self tapping metal screws, small I beam we found for the base bar to mount winches, and 2 winches (one we salvaged and another from Tractor Supply @$20) for pulling each direction.
We welded a bar to slide along the bottom of the bin to agitate the castings through the grate. I have tried other versions without the cutting bar, and castings tend to get clumpy and stuck. Stay tuned for the big reveal when we add worms and a few finishing touches.
Join Dr. Jerry Parsons, TexasRedWorms, and the Garden Volunteers of South Texas Jan. 23.
23 JanThe Garden Volunteers of South Texas will be hosting their monthly “Essentials of Gardening” from 12:15 – 3 PM tomorrow at the San Antonio Garden Center (3310 N. New Braunfels at Funston, next to the Botanical Garden.) Dr. Jerry Parsons will be speaking first on year round garden planning. I will follow him w/ a worm composting presentation. Admission is free but a $5 donation is encouraged. Come join us!
Harvesting Worm Castings w/ a Homemade Sifter
23 MarFor large jobs of sifting worms from castings or compost I use my Texas Worm Harvester, but for smaller jobs I have built a small box sifter. With some scrap materials, and the left over 1/4 inch wire mesh I had I put together this sifter. I have also seen where other worm farmers use 1/8 inch screen, for my use I have found the 1/4 inch to do just fine. Separating worms from castings using this or the harvester method is the first step I take and removes most of the worms are course unprocessed organic matter. I do spend time picking out tiny worms and eggs, but losing a few is not a big deal. Here is a picture of a tiny hatchling that I found while harvesting castings. As you can see, or maybe not, these little guys are hard to find. This little thread of a worm was wiggling which made him easier to see.
