Hello all,

I am the sort of person who believes in big pots. I am only a bit more cautious when dealing with xerophytes. In the beginning, I followed the herd and moved the plants up two inches. Now If I have a four , I might move it up to an eight or ten. A ten to a thirteen ( cuz that what I always have on hand),etc ..

If have a plant that seems to have a very vigorous root system, the jumps between sizes may be more extreme. I figure it's time to pot up when I see roots peeking from the bottom or when an inspection shows roots going around the surface of the rootball.

I do use a very porous mix as follows

one part loam

one part promix bx

one part play safe mulch ( coarse cedar)

one part pine mulch fines

one part coarse perlite

a handful or two of slow release fertilizer ( using one of those big muck buckets).

If I'm potting up aroids, I might be inclined to increase the play safe mulch. I used to use orchid bark , but the mulch runs about $3 for two cubit feet.

I don't know if the plants appreciate the big pot more or the aerated media but i am generally successful in growing plants to specimen size.
