I would like to talk a little about, and hopefully dispel the myth that certain plants 'like' or 'prefer' to be grown tight (under root-bound conditions). Maybe we can also understand that no plant will 'do well' when it's pot-bound, if you are using a plant with plenty of room for its roots as the standard to judge against. If plants did better growing under root-bound conditions, it would seem that Mother Nature would have arranged for in situ (where they naturally occur) plants to grow with their roots in tight little cones or cubes, yet we never see that occur. While it's true that we may be able to use the STRESS of our plants being root-bound to bend plants to our will and achieve OUR goals, the fact is that this serves US well, and not the plant.
Lets examine what 'growth' is. Growth is simply a measure of the increase in a plant's biomass, how much bigger it has become (the weight of the sum of it's parts), and is the actual measure of how 'well' a plant is doing. We know that tight roots restrict growth, reduce the amount of extension, and reduce the potential for an increase in mass, so even if we THINK plants are doing well because we use the stress of tight roots to get them to bloom or grow in a particular habit that we like, the truth is tight roots are stressful and plants would rather have plenty of room for their roots to grow so they could grow as mother nature intended. No one is more aware of the negative influence tight roots has on growth than the bonsai practitioner who uses that tool extensively to bind down the plant's growth habits so the will of the grower, not the 'will' of the plant, prevails. Using tight roots as a tool to achieve an end is all about the grower's wants, and not the plant's.
If we chase this a little further, we can see the reasons that it is suggested that particular plants might like root-bound conditions. Tight roots alter the plant's growth habits, and the stress of tight roots can cause other physiological responses like bloom induction. Again, this is happening because of stress, and is the plants unhappy response. Bright flowers make the grower happy, but from the plant's perspective the view might be entirely different.
Where I was really heading when I started to write this is: There is a relationship between plant mass (size), the physical characteristics of the soil, and the size of the container. In many cases, when we are advised that 'X' plant prefers to be grown tight, we are being told that this plant won't tolerate wet feet for extended periods. Someone somewhere assumed that we would be growing this 'X' plant in an out-of-the-bag, water retentive soil, and a big pot o' that soil stays wet for a long time, so we better tell these people to grow this plant in a tiny pot so the plant can use the water in the soil quicker; then, air will return to the soil faster and roots won't rot.
If you place a plant in a gallon of water-retentive soil, it might use the water fairly quickly, at least quickly enough to prevent root rot; but if you put the same plant in 5 gallons of water-retentive soil, the plant will take 5 times as long to use the water and for air to return to the soil, making it much more probable that root rot issues will arise. So lets tell 'em to grow these plants tight to save them (the growers) from themselves ... because we KNOW they're all going to be using a soggy soil.
Key, in this instance, is the soil. If you choose a very porous soil that drains well and supports no (or very little) perched water (that water in the saturated layer of soil at the bottom of the pot), you retain the capability of growing a very small plant in a very large pot, and making the plant MUCH happier than if you were growing it tight. You still have the option of choosing those plants you prefer to stress intentionally (with tight roots) to get them to grow as YOU please, but for the others, which comprise the highest % of houseplants, it makes much better sense to change to a soil that allows you to give the plant what it needs to maintain peak vitality, than to do something that stresses the plant as the large part of a strategy to keep it viable.
