Biodegradable

For plants that don’t like having their roots disturbed a very effective approach is to use bio-degradeable pots. These can then be planted straight into the soil and the roots will just grow through them. Various types are available but steer clear of peat ones because of the environmental impact - alternatives include recycled fibres, coir and even dried cow manure! The main problem is that you can’t pot them up with fresh compost so I think these are best used for fast-growing plants such as squash that will be hardened off and planted out within a few weeks.
It is easy to make your own biodegradable pots. There are simple instructions available for making pots out of newspaper but they usually need a firm tray to keep them upright and in my experience they are hard to make with enough depth for many seedlings. An alternative is to use cardboard tubes stood upright in a tray with compost stuffed in as they provide better depth. I use these for peas and beans in a similar way to roottrainers.
Recycle and Reuse
You can often reuse perfectly good plastic containers rather than sending them to landfill:
- Almost any plastic container can become a plant pot as long as you punch plenty of holes in the bottom for good drainage. This is important because soggy roots can’t get the oxygen they require and that will stunt growth.
- Many thousands of plant pots and trays are thrown away every year by people who buy their bedding plants from garden centres. Just ask any neighbour you know who does this and you can have an endless supply of perfect pots with perfectly fitting trays which make them easy to move when hardening off.
- Old guttering can be used to raise peas and beans. Once they are a few inches tall you can slide the plants out of the guttering into a trench for planting. It’s a little tricky the first time you try it but it works well for succession sowing where the plants will be in the ground quite quickly and so don’t need a lot of depth for roots.
This snippet is from http://www.growveg.com/growblogpost.aspx?id=134. There are some great ways to re use old household items such as toilet roll tubes and cardboard boxes. From reading this it gave me the idea of turning my packaging into a secondary use for the garden. Due to the three triangular shaped storage sections being quite deep it is ideal for planting beans. The cardboard will eventually degrade with use causing no harm to the environment.
