There is no rule stating that seed starting necessitates extravagant flats or trays. For the financially prudent gardener, investing in pots and containers is a clear no-go. A minimal portion of your gardening budget should be earmarked for containers. Why? Because they are readily available for free or at a low cost! There are numerous do-it-yourself (DIY) options to explore!
When searching for items to repurpose as seed starting containers, opt for pots that allow for proper drainage. You can create holes to facilitate water drainage. In cases where puncturing the container is not feasible, place rocks at the bottom to prevent the plant’s roots from sitting in water. Consider container sizes based on whether you intend to repot seedlings later on or if you plan to transplant them directly into the garden.
I prefer placing my containers on a tray to contain any accidental soil or water spills. I also recommend watering seedlings from below to prevent damping off. Some time ago, I invested in sturdy seed starting trays, anticipating their longevity. Any type of tray will suffice. Check your kitchen cabinets for old serving trays.
Egg cartons, Chinese takeout containers (plastic or paper), paper towel rolls, dollar store options, coffee pods, yogurt or applesauce containers, paper cups, bulk plant trays, Jiffy or coir pellets, clamshells, juice or milk cartons – these are all inexpensive or free options for seed starting containers. Each option has its unique benefits and can be easily sourced or repurposed for gardening.
If you still consider purchasing specialty trays and flats, that’s perfectly acceptable. However, prioritize investing in high-quality containers that can be reused annually. Regardless of the container chosen, ensure proper sanitation if it is being repurposed or reused.
