Also, some cells become over-saturated while seedlings on the edges may dry out faster. I've tried lifting the flat and dumping water underneath into the tray. Top irrigation works ok, but can be quite messy inside the home. In my personal experience, I've found the trays to be hard to water. They may not be the best solution in a small scale home environment. But seedling trays are most useful in a nursery or greenhouse application. They devote only a small amount of potting media to any given plant. Such systems are very common and cheap to implement. The trays also can hold excess water, keeping things neat. The tray offers structure during transport. Each flat is usually placed into an accompanying tray. This high density system allows a lot of plants to be squeezed into a small space. SEEDLING FLATS / CELL PACKS & TRAYS: Seedling flats offer tiny cells of soil for each plant. So you will be stuck buying new ones every year. One final thought: these are consumable products. Growth will not be restricted and you should have good results. If you see tips of roots, then once you plant this in the ground, you know the roots will be ready to quickly spread out into the native soil. Have plant roots begun to poke through the edges? These pots are meant to air prune the roots, preventing root spiralling. One way to tell is to examine the outside edges of the pot before planting. If your pot is kept moist and is breaking down quickly you may be just fine.
To avoid this, I peel away the pot and toss the pieces in the ground at planting time. If this happens, your plant may become root bound and its growth will be stunted. Some gardeners have complained that their biodegradable pot never properly decomposed during the growing season. Processing cow poo into a pot is also a cool way to utilize a resource that might otherwise be considered waste. Coir is a more renewable alternative since it is a by-product of the coconut industry.
Some environmentalists oppose the use of peat moss for horticultural use due to the negative impacts of harvesting it. All of these are marketed with the intent that you can just plant the entire seedling into the ground and the pot will break down, allowing the seedling to grow to mature size.Įach of these materials has varying levels of sustainability. And CowPots are derived from composted cow manure. Coir or Coco pots are made from recycled coconut fiber. It's possible to find pots made from several biodegradable materials. COW / PEAT / COIR POTS: Perhaps you've see square or round pots that have a texture similar to cardboard pulp.
