Don't know what a 1 gallon pot is in size but generally the more room and less crowding they have the faster they'll grow. The first few years they grow continuously, sometimes with up to 3 leaves at one time. While they're in this growth stage you don't want to be repotting them (disturbing the roots) again because they've outgrown their container or are becoming too crowded. So better they have their own individual pots rather than be crowded 3 to a pot.

Depending on your climate, full sun could be a bit too much for them. Very bright but filtered light would be better.

I do notice a flush of new roots accompanying the ones with the rising shoots. One of them already has a shoot taller than the original which will likely double it up, but the diameter is around double that of the old one.

The ones outside appear to handle full sun in the 70s just fine. They are growing in VA so I guess the sun is not super bright, but I don't see any adverse effects from the sun so far so I guess they can handle it right?


I guess I'll make sure they get their own pots once each one has a shoot that is getting nice and big already, forcing me to have to give each one its own space eh. I wonder when I will get more than 5 leaflets per leaf.

I've been selling them off slowly and will only keep the largest ones which are currently close to 5/8 inches in diameter with tubers likely getting up to the size of tennis balls. They are getting heavier by the day. They aren't that tough to grow, and yes, they do seem to handle full sun pretty well once fully adapted and the sun is already as strong as it will get up here.

Ahhhhh... supporting one's "habit." <G>

I must admit that the desire to grow these amazing plants can be addictive. Even though I live in the tropical region of Australia my altitude means that winters can bring some "killer" low temps. This time of the year (our winter) I often have to muster my small titanums into the house each evening when the 'ol sun goes down. I don't know what will happen when one of these suckers gets so big that mobility becomes a major logistical exercise.

Right now I'm experimenting with a cheap, effective means of providing heat for those cold periods just before sunrise. One possibility is an inner tube from a tractor tyre, filled with water and heated by one of those 25 watt reptile heating cables. If it works, put the pot right in the guts of the tube. As they say, "necessity is the mother of invention."<g>

I'm knew to all this, I notice you have the pots in bags. Is that to hold the moisture in the dirt or the keep the counter top tidy?

It serves both purposes,and makes it so I hardly have to water them. I have since sold or donated all of them but 1.
