Understanding the Role of Flowers in Compost: Greens vs. Browns

Before diving into the specifics of composting flowers, it’s essential to understand the basics of green and brown materials in composting. Greens are moist, nitrogen-rich organic materials, while browns are dry and carbon-rich. Examples of greens include vegetable peels, fruit scraps, grass clippings, and yes, flowers. Browns, on the other hand, include items like sawdust, shredded newspaper, and dried plant matter.

Flowers can be categorized as either green or brown compostables. Fresh, moist flowers are considered greens, while dried flowers fall under the browns category.

Step-by-Step Guide to Composting Flowers

Composting flowers is a straightforward process, but following best practices ensures effective decomposition. Here’s how you can compost flowers in bins, tumblers, heaps, or piles:

  1. Preparation: Chop the flowers into smaller pieces to increase their surface area, aiding faster decomposition.
  2. Sorting: Remove non-compostable parts like thorns or bulbs. While thorns can decompose, they may take longer and potentially affect the compost’s pH balance.
  3. Mixing: Combine fresh flowers with other greens like vegetable scraps or grass clippings. If composting dried flowers, mix them with browns like shredded cardboard or dry leaves.
  4. Layering: Add the flower mixture to your compost bin in layers, alternating between greens and browns.
  5. Moistening: Sprinkle water gently between layers to maintain moisture, which accelerates the composting process.
  6. Turning: Start turning the compost every couple of weeks to enhance microbial activity and decomposition.

A well-managed compost bin can decompose flowers within six months to a year. However, without proper composting practices, it could take longer.
