Have you tried vermicomposting, otherwise known as worm composting? This simple process mixes food scraps with yard waste and other organic materials in an enclosed area containing specific types of worms. The worms (and associated microorganisms) eat the organics and turn them into a beautiful light and fertile soil amendment. This compost is almost magical! It’s packed with nutrients, improves soil structure, increases drainage and appears to improve plant growth while decreasing pest damage and plant diseases. Not only environmentally friendly, vermicomposting doesn’t require much space, is inexpensive and easy, and it’s a fun hobby for the entire family.

The Worms

The two recommended worms for vermicomposting are Red Wigglers (Eisenia fetida) and European night crawlers (Eisenia hortensis). The latter grows bigger, eats coarser food and may be heartier. They each eat their own weight in food every other day. Do not use native earthworms, as they do not live well in bin conditions.

Most people begin with 1 lb (16 ounces) of worms. These will eat 8 ounces of food every day.

TIP: To determine your average daily food waste, weigh your food debris each day for a week. Add these amounts and divide by 7. (Do not include meat, fish, oily scraps, fat chunks, bones, or dairy products, as they are not suitable for the worms or compost.)

When you know your amount of food debris, buy twice as many pounds of worms. For example, if your average daily food debris is 1 pound, order 2 pounds of worms. If your average daily food debris is 4 ounces, order 8 ounces of worms.

The Worm Bin

Your worms will need a comfortable place to live. Provide a bin with a surface area that equals the weight of the worm order. In other words, if you order 2 pounds of worms, your worm container will require at least 2 square feet of bin surface (but should be larger). This could be 1’ wide by 2’ long.

Use non-treated wood, plastic, rubber or galvanized bins. A larger container houses more worms to compost more material. Worms do not burrow deeper than 24” therefore the bin should be less than 24” deep.

The bin needs a removable cover to protect from rain, light and drying out. Remove it if the bedding becomes too wet, but place a screen across the top to prevent worms from escaping. If needed, use a moistened strip of burlap or canvas to add moisture to the bin.

Unless using wood, which is naturally porous, provide ventilation in your bin by drilling 12-18 1/8” holes on all four sides. Drill holes on the bottom to prevent your worms drowning if moisture builds up.

Remember, your worm population will increase. When sizing your bin, allow an additional 40 percent of surface area for the increase in addition to the initial population’s requirement.

Positioning Your Bin

Where you put your bin should be convenient for both you and your worms. Elevate the container on bricks to improve ventilation and drainage of excess moisture.

Place the worm bin where it will not receive direct sunlight. In a shed or garage, under house eaves or other shade structure to maintain a temperature above freezing and below 85 degrees is perfect. In the winter, prevent freezing and insulate with sheets of foam on the top and sides, add a heating pad to one side, or move inside a building if needed.

Bin Bedding

Before adding your worms, you will need to add bedding to the container so they have a place to burrow. Soak and squeeze out the excess water from shredded fibrous materials such as newspaper, egg cartons or single-layer cardboard boxes. Mix in dry grass, brown leaves and/or straw. Add sawdust or aged manure, if available. Cover with a thin layer of well-moistened soil. This bedding will give your worms a great start and will help feed your compost.

Feeding Your Worms

Until your worms begin multiplying, only feed them once a week by adding a small amount of food scraps. Chopping or breaking food into small bits helps the worms eat the scraps faster and reduces any smells and fruit flies. Mix the food lightly into the bedding on one side of the worm bin.

Ideal foods to offer your worms include eggshells, non-citrus fruits, coffee grounds, unbleached used coffee filters, leafy green vegetables, rice, grits and vegetable scraps. Do not include meat, fish, oily scraps, fat chunks, bones, dairy products such as milk or cheese or cat or dog waste. Avoid eucalyptus leaves, as these contain a natural insecticide which could kill the worms. Additionally, if adding lawn clippings, be sure the grass hasn’t been chemically treated. Green foods such as leaves, vegetable tops and green grass add additional nitrogen to the finished compost. Eggshells increase the calcium in the final compost and brown foods such as paper, wood chips and leaves increase phosphate and carbon. The more varied your worms’ diet, the richer your compost will be.

When the worms begin to multiply, provide a weekly quart of food scraps per square foot of surface area. If your bin is 2’ square, provide 4 quarts of scraps per week to nourish your worms, but avoid overfeeding. One way to tell if you are feeding too much is by smell. If it smells bad, food is rotting instead of being eaten. Reduce the amount of food going into the bin until the smell disappears.

When adding food, be sure to check the amount of bedding. The bin was full of bedding when the worms were added. When reduced to half, add more newspaper or cardboard strips, hay, straw, etc.

Watering Your Worms

Check the bin every other day and moisten the material, if needed. It should be moist but not wet. Note that the types of scraps you add will contribute to the moisture in the bin, and you do not want any puddles or sopping that could suffocate and drown your worms.

Harvesting Compost

Your worm-assisted compost should be ready in 4-6 months. The easiest way to collect the compost is to scoop out small piles of the material and place onto a flat surface. Remove as many worms as possible and return the un-composted materials and worms to the bin. You may use a wire mesh netting as a screening device. Add more bedding and let the cycle begin again.

After removing the worms and chunks, what’s left? The grand prize of worm castings (poop)! This is the “magical compost.” Some people even call it “black gold” – it’s that fantastic for your garden.

Raising worms and producing your own super compost is easy and fun. Plus, it removes food waste from the local landfills and enriches your garden. What’s not to love?

Perhaps you have used compost tea on your plants and saw the amazing effect it had. However, if you think your plants loved their compost tea, try giving them a drink of worm-casting tea. No, it’s not the liquid dripping from the bottom of an elevated worm bin – so what is it?

Making Worm-Casting Tea

This “tea” is a liquid concoction made by steeping worm castings (worm poop) in water. This is an extracting process that draws the nutrients from the castings into the water so they can be more easily and quickly absorbed by thirsty plants. Use it on your plants by drenching the soil around the roots or spray onto the leaves for foliar absorption. Both spraying and drenching eliminate the labor of spreading solid compost. And, applied as a liquid, plant resistance to pests and diseases and microbial activity in the soil are all increased. While compost tea contains many beneficial microbes, it’s nothing compared to worm-casting tea that contains a much larger and diverse microbial population due to the various physiological life processes of the worm.

To really kick up the benefits of worm-casting tea, try aerobically brewing a batch. This simple process increases the microbial populations by circulating the microbes in a nutritious and aerated solution to double the population every 20 minutes. This method also eliminates any possibility of E. coli, which can be present in both compost and worm-casting tea brewed by extraction.

To brew your worm-casting tea…

1. Connect 3’ of tubing to an air stone. Attach other end to small air pump.
2. Put 4 gallons of water into a clean 5-gallon bucket. Let sit for 24 hours to allow chlorine to dissipate. Alternatively, use non-chlorinated water.
3. Add:
   1. ¼ cup sulfur free molasses or corn syrup
   2. 1 tablespoon water-soluble sea plant extract
   3. 2 tablespoons soluble fish power or liquid fish
4. Plug in pump and place air stone at bottom of bucket to begin agitation.
5. Add 4-8 cups earthworm castings, crushed into small bits, if possible.
6. Brew until a froth or slime appears on the water surface. The smell should now be gone or very weak. This indicates the maximum population has been reached and no food remains for the microbes to eat. This solution may contain over one billion microbes per teaspoon of solution! The overall brewing time is temperature dependent, however, and warmer solutions will brew more quickly. At all times, leave the bubbler on to continue oxygenating the microbes.
7. Strain the solution to remove any solid particles. Apply to plants as soon as possible to take maximum advantage of your tea’s nutritious properties.

Note: The odor should be minimal or vaguely pleasant. If the smell is strongly unpleasant or similar to sulfur, do not use. Pour it over some weeds for a natural herbicide instead.

You can use your worm casting tea anywhere in your garden: upper and lower sides of leaves, on flowers, vegetables, trees, shrubs or soil. Spray in the early morning or evening or in the shade during the rest of the day. Use the remaining castings as you would any compost, after all, they still contain a diverse microbial population!

Now, raise your teacup and toast to a healthy, luxurious garden and landscape, all thanks to nutritious worm-casting tea!

Late winter pruning is often recommended for many trees and shrubs. Pruning the plants while they are dormant is less stressful for the plant and it’s also easier to view the structure of deciduous trees and shrubs without leaves to ensure the pruning helps create the desired shape. It’s also a time of the year when late winter sunshine makes us all long to be in our gardens and pruning is an excellent job to get us out there.

Pruning Tools

To get out and get pruning, you will need the proper tools. There are several types of pruners that should be in every serious gardener’s tool shed.

• Hand Pruners
  The simplest tool, but the hardest to choose, is the hand pruner. There are two distinct styles of hand pruners: the anvil type and the bypass. The anvil pruner is good for pruning deadwood or undesirable growth. For more valuable specimens anvil pruners tend to smash the wood during cutting, leaving the wound open to insects and disease. Bypass pruners are like a pair of scissors and give you an easier, cleaner healthier cut. Different hand pruners are available in different sizes and grip styles, including options for both right-handed and left-handed gardeners. To get the best results, it is important to choose a hand pruner that feels comfortable but still provides adequate strength for the job.

• Lopping Shears
  Another tool that comes in handy is the lopping shear. They are used for making larger cuts up to 1-1/2″ in diameter, and have longer handles to provide more power without stress or strain. The longer handles also provide a better reach than hand pruners. They are also excellent for clearing away undesirable growth in your yard, including trimming hedges.

• Pole Pruners
  The last tool you’ll need is a pole pruner. It is a combination lopping shear and pruning saw. The pole pruner extends out to twelve feet and can be used for making small cosmetic cuts or larger limb removals without needing to set up a ladder. Pole pruners are also useful in dense canopies when using a ladder would not be practical or suitable.
