Repot pot sizes

[cloudswinger]

If I have plants that are in 2.5 or 2.25 pots, should I go to 3 inches or 4. The 3 inches seem kind of small in relation to the current size which are square. I'm using the round translucent with slits, and would like to stay with the same type.

It would depend on the amount of roots. You might be better off to stay in the same size. post a pic of the roots so we can help.

I believe if you measure the diagonal of a 2.5 inch pot you will come up with about 3 inches. Probably a 2.5 inch pot would fit inside a 3 inch one. So 3 inch is only slightly larger. I would consider a 3.5 inch round pot or a 3 inch square one. (provided you don't overpot or have too much space from roots to wall of pot.

It depends on many things:
1) type of orchid
2) how much it has grown
3) how big is the root mass
4) what the cultural requirements of the orchid are

I frequently repot orchids in the same size pot. What more can you tell us?

Hi.
I agree with Kmarch.
I grow Cymbidiums from flasks and they start their life in 48 mm square tubes, 1 per pot.
They stay in this until the roots fill the small pot, usually about 9 to 12 months.
Then into 100mm round tubes.

I also grow a lot of Paphs and after I break the community pot up after 1 year from deflasking.
I also plant them into the 48 mm square tubes

Now if I then repotted them after 1 year into the 100mm round tubes I would lose the lot.
Reason "Overpotting" As they say "Horses for courses"
If we knew the type of plant it would make the problem easy to answer.
My 1 penny worth.
Cheerio

Some are bare root which were recommended to use 2.5-3 in pots, but I can't get all the roots in without coiling them. A mini-cat with roots sticking out of the bottom. A bollophylum with a root tip right at the edge of the top of the pot.

Bulbos are veyr rambling orchids. They grow roots and vegetation all over, especially once they're well establishied and getting good culture. A root tip at the edge of the pot does not necessarily indicate a need to repot. When wes it last repotted?

The mini-cat might need repotting, but I have several orchids with roots coming out the bottom which I'm not going to repot. Does the mini-catt have room to grow more pseudobulbs? And when was it last repotted?

And finally, what genera are the bare root orchids?

[cloudswinger]

t's not a bulbo, it's a bollopetalum, I misspelled. cross between a bollea and a zygo. And the tip of the root had gone down to the bottom of the pot and was on it's way back up. I don't know when any were last repotted, I just got them from the grower.
The bare roots are a odbrsa, a bulbo and a paph. The bulbo I mounted, it was the odbrsa that I couldn't coil enough to get into the smaller pot.
