Soils and potting mixes that include compost produce healthier plants whether it is used for indoor gardening, rose gardening or vegetable gardening. Although it won’t guarantee the best vegetables, fruit or flowers, composting can help make up for all kinds of plant deficiencies by improving your garden soil. Adding compost will boost plant health and helps the environment by reducing the amount of organic material that goes to waste (literally) in landfills.

Following are materials to add or not to add to create optimal composting for gardening:

Materials to Add

Add aged manure, cottonseed meal, alfalfa meal, blood meal or a compost starter. These elements are rich in nitrogen and will help jumpstart the microbes responsible for breaking down the organic matter into compost.

Add a mixture of green materials (grass clippings, food scraps and manure) with brown materials (dead leaves, hay, wood chips and shredded newspaper) to add necessary nitrogen and carbon. Both elements create rich compost for quick decomposition. A ratio that combines equal portions of both works best.

Add coffee grounds and let the worms help with the composting.

Add algae and seaweed. Rinse off any salts before using.

Add straw for an excellent source of carbon but make sure it doesn’t contain weed seeds. Materials Not to Add

Do not add fats, pet droppings, or animal products. These elements attract pests to the pile and can spread disease.

Do not add ashes to the compost bin (or do so sparingly) since they are alkaline and affect the pH of the pile.

Do not add plants treated with pesticides or herbicides (like weed and lawn clippings).

The compost is finished when it looks, feels and smells like rich, dark soil. You should shot be able to recognize any of the elements placed in it. Finished compost is generally less than half the volume of the materials placed in the bin, but it’s much denser.

Compost piles should remain damp but not saturated (think of a wrung out sponge). Aerate the compost pile regularly (every two weeks) to create air spaces which will reduce the smell.

Apply the finished compost to your garden about 2 to 4 weeks before you plant to give the compost time to integrate and stabilize within the soil.

Popular Questions

What materials should you add when composting for better gardening results?

Combine nitrogen-rich materials such as fruit and vegetable scraps, coffee grounds, fresh grass clippings, and green plant trimmings with carbon-rich materials like dry leaves, shredded paper, straw, and untreated cardboard. Aim for a balanced mixture rather than adding only food waste or only dry material. Chop large pieces and mix the ingredients so the pile has enough air and moisture to break down efficiently.

Which kitchen scraps and garden materials are best for optimal composting?

Suitable kitchen additions include vegetable peels, fruit scraps, coffee grounds, tea leaves, and crushed eggshells. Garden materials such as leaves, grass clippings, weeds without mature seeds, plant trimmings, and small twigs can also be composted. Avoid meat, dairy, oily foods, diseased plants, pet waste, and weeds carrying seeds because they may create odors, attract pests, or spread problems.

How do you balance green and brown materials in composting for gardening?

Green materials supply nitrogen, while brown materials supply carbon and help maintain airflow in the pile. Add several parts brown material for each part green material by volume, adjusting the mix if it becomes wet, compacted, or slow to decompose. If the compost smells sour or rotten, mix in dry leaves, shredded cardboard, or straw; if it stays dry, add moist green materials or a small amount of water.

What should you avoid adding to a compost pile when choosing materials for gardening?

Do not add treated wood, glossy or heavily coated paper, synthetic fabrics, chemicals, or plants treated with persistent herbicides. Meat, bones, dairy products, fats, and oils can attract rodents and other pests in a typical home compost pile. Keep pet feces, diseased plant material, and invasive weeds out unless you use a managed system capable of reaching and maintaining sufficiently high temperatures.
