Why May Is Excellent for Worm Multiplication

Temperatures are usually ideal (60–77°F / 16–25°C) for rapid breeding. Worms can double their population every 2–3 months under good conditions. Abundant green waste and kitchen scraps make feeding easy and cheap.

Your May Multiplication Checklist (Do These 4 Things)

Do these 4 things for best results:

1.Feed consistently but not too much — Give 1 - 1.5 cups of food per pound (450g) of worms every week. Slow down the food addition if you notice that the worms are not keeping up. 2.Keep bedding moist — Like a wrung-out sponge (60–80% moisture). Do the squeeze test: Take a fistful of bedding in your hand and squeeze it. If a few drops of liquid show up, the moisture level is perfect. 3.Add a little carbon-rich bedding weekly — Shredded corrugated cardboard, newspaper, or coconut coir to balance nitrogen-rich food. 4.Maintain good airflow — Loosen the top layer gently with a hand fork every second week. Make sure your tool doesn’t have sharp edges to avoid harming worms.

Worm Food

Why Feeding Is One of the Most Important (and Tricky) Parts of Worm Composting Feeding your worms correctly is the heart of successful vermicomposting. Get it right and your worms will multiply quickly, produce beautiful rich castings, and stay healthy for years. Get it wrong and you can lose your entire colony in just a few days. Many beginners (and even some experienced worm keepers) make fatal mistakes in this area: overfeeding, feeding the wrong foods, burying nothing and attracting fruit flies, or letting the bin become too wet or acidic. These errors often lead to odors, escaped worms, or a complete system collapse.

The good news? Once you understand a few simple principles — balance between “greens” (nitrogen-rich food) and “browns” (carbon-rich bedding), proper portion size, and consistent burying — feeding becomes easy and rewarding.

In May, with warmer temperatures and more kitchen scraps available, smart feeding is especially important because your worms are actively breeding and can turn food into castings faster than ever. Below is your practical May Feeding Guide to help you avoid the common pitfalls and keep your worms thriving.

Feeding Guide for May 2026

How Much per week - per 1 lb / 450 g of worms)

Vegetable & fruit scraps, Amount: ½ – 1 cup. Tips: Chop finely and bury under the bedding.

Coffee grounds, Amount: ¼ cup

Crushed eggshells, Amount: 1–2 tbsp. Tips: Great for calcium & grit. Garden greens & trimmings, Amount: ½ cup. Tips: Chop small. Excellent for worm growth and activity.

Bread, pasta, rice, Small amounts only. Amount: 1–2 tbsp. Tips: Feed occasionally.

Meat, dairy, oily food → No. Amount: None. Tips: Avoid completely.

Citrus & onions → Very little. Amount: Max 1 tbsp. Tips: Can make the bin too acidic.

(The amounts given are general guidelines. If your worms are feeding faster than expected, increase the food slightly. If food keeps building up, reduce the amount.)

Pro Tip:

Always bury food 2–3 inches deep to prevent fruit flies and odors.

Tip of the Month: “The Coffee Filter Method”

Save your used coffee filters (with grounds inside) and place them directly on top of the bedding. The worms love the grounds in moderation, and the paper filter slowly breaks down with time. This is an easy way to feed while reducing kitchen waste — many readers report excellent results with faster worm activity.

Quick May Troubleshooting

1. Bin getting too warm? Move it to full shade, insulate it with wet towels or place it in a polystyrene box on hot days. 2. Fruit flies appearing? Stop feeding for 3 days and cover the surface with 1 inch of damp shredded newspaper. 3. Worms slowing down? Check moisture level and add more bedding — they may be too crowded.

A polystyrene box like the one above is a great protection for your worm bin against extreme hot or cold weather.
