Browse Forums Landscape & Garden Design 1 Jan 05, 2010 2:48 pm We've noticed a few plants we planted last spring are growing in cardboard pots. We didn't even see them when we took the plants out of the plastic containers and planted them but now that I guess some of the soil round the stem has washed away, there they are. Or maybe the root growth is pushing them upwards. Anyway, some of these plants aren't doing too well in the hot weather and I'm wondering if these cardboard pots are impeding root growth to a detrimental degree? I would have assumed they're biodegradable but they don't look like they're going to break down any time soon. Should I remove the cardboard and replant now, wait until autumn to do so, or just give them plenty of water and some patience? Re: New plants - cardboard pots inside plastic pots 2Jan 05, 2010 7:15 pm It's cool Macy It isn't cardboard but the idea is similar. They are fast becoming the norm for growers. Some plants are even sold in retail garden centres in pots made from the same stuff. Totally biodegradable traditionally a grower would by in tube stock (tiny plants in things the size of a film canister almost but a bit bigger) and pot on those into 140mm pots or even straight into 175mm or 200mm pots. They would have to remove the tube and pot the plant up and when there are 10's of thousands of these to do, it's not much fun So some clever sorts created these bloody wonderful biodegradable tube pot thingys and now the grower can just bung in the plant, pot and all and grow it on. Cuts out so much fluffing around and the plants have no root disturbance meaning they grow faster and healthier Now the rates at which the biodegradble pots break down varies and both growers and manufacturers are still ginning around with the formula required best for each individual grower. That means we still see them in the top of the pot when purchasing or later when planting or growing. Expect to see these as becoming more common instead of plastic pots in nurseries and garden centres in years to come too. Then there will be a biodegradable pot inside another biodegradable pot But no plastic We will also start seeing "rocket pots" and plastic pots with just one hole in the centre of the base Australia in many peoples opinions leads the world in plant growing but others will not see that point of view. The people who do are the ones getting results and getting healthier stronger plants to gardeners and landscapers They are made from bamboo or corn starch most commonly.
