>=3B Steve=2C
>=3B Yes=2C some rainforest plants are rootbound in the wild if they are
>=3B lodged in small crevices or holes in limestone=2C e.g.=2C various
>=3B Amorphophallus.
>=3B I am a strong advocate of maintaining plants=2C any plants in pots=2C
>=3B under rootbound conditions for the reasons that others have given here
>=3B and more. It boils down to the health of the roots=2C which is really
>=3B the greater part of horticultural method. You will notice that a plant
>=3B is at its best when it is well along after repotting=2C becoming
>=3B pot-bound=2C yet before it is really cramped. This ideal state does not
>=3B last more than a year or two in many cases=2C unfortunately.
>=3B The rootbound condition necessitates more frequent and more thorough
>=3B watering (a good thing for many aroids) but otherwise should not be a
>=3B problem for the grower. Shortly before a plant is simply obnoxious
>=3B because it dries and wilts all the time=2C it should get a bigger pot.
>=3B Naturally there are exceptions=2C such as fast growing plants or aquatic
>=3B aroids=2C that can be "overpotted" with no ill results. If plant health=2C
>=3B time of year and other conditions are ideal then it may be fine to put
>=3B a large pot-bound Philodendron in a 6" pot directly into a 5gal tub if
>=3B it is a large species.
>=3B I would add that the firmness of the container is important too. Roots
>=3B seem to need physical resistance=2C and I have generally had much better
>=3B results with very firm=2C stiff pots (good polstyrene=2C clay=2C wooden
>=3B boxes=2C etc.). Any squishy-soft pots are thrown away. As a consequence
>=3B of "greater efficiency" in modern injection molding I have lots of
>=3B plastic pots 10 years old or more that I value highly.
>=3B Particle size of potting media is another consideration=2C in addition
>=3B to others. It is a complex topic that is not often properly addressed.
>=3B Best of luck with you article!

>=3B >=3B Some of you know that I love to chase down the sources of horticultural
>=3B >=3B beliefs. If you have ever spent time on any plant forum you know the common
>=3B >=3B advice is to keep your plants root bound=2C or at least when you repot give
>=3B >=3B the roots only an "extra fingers width" on each side the pot.. My question
>=3B >=3B is where do that advice originate? Why do we believe it? Is this really
>=3B >=3B good growing advice or just an old wives tale? Are plants in the rain
>=3B >=3B forest root bound?
>=3B >=3B
>=3B >=3B I understand that nursery men prefer to start their plants in small pots
>=3B >=3B and allow the roots to fill it before stepping the seedling up to a larger
>=3B >=3B pot.. My understanding is they do this in order to encourage a hearty root
>=3B >=3B system first. But it appears some growers may have taken this advice to
>=3B >=3B excess and always keep their plant's root bound. Should we always keep our
>=3B >=3B aroids in pots so small their roots are for ever crowded=2C or give them space
>=3B >=3B to grow?
>=3B >=3B
>=3B >=3B We always have new growers looking for good growing advice. If you have
>=3B >=3B adopted a small pot policy please tell us why. If you are an experienced
>=3B >=3B grower and prefer a tight pot method I would enjoy knowing the reasoning.
>=3B >=3B Many of you don't know that I have written for years for a variety of
>=3B >=3B magazines and I have another train of thought in this area. I am now
>=3B >=3B working on a new article to explain about aroid growth=2C a plant's need for
>=3B >=3B oxygen around its roots as well as how to keep their root systems healthy.
>=3B >=3B This discussion will help me to formulate my article.
>=3B >=3B
>=3B >=3B If you are new to growing=2C please chime in.
