Planting bulbs in straight, evenly spaced rows can be time‑consuming and surprisingly difficult to keep consistent. One practical solution is using recycled egg cartons as a planting guide inside a trench. This method is simple, low‑cost, environmentally friendly, and especially useful when planting dozens—or even hundreds—of bulbs at once.

Below is a complete guide to how the method works, which bulbs are best suited for it, and how to maximize your chances of strong, healthy blooms.
How the Egg Carton Trench Method Works
The idea is to combine two helpful tools:
A shallow trench for uniform planting depth
Cardboard egg cartons for perfect spacing and organization
The cartons act as biodegradable planting trays. They separate bulbs evenly, prevent rolling or shifting, and slowly break down in the soil, adding small amounts of organic material.
