Sorry to bump my own question but,

This guy is growing so fast I can't stand to see him in that tiny pot, (he looks like he might climb right out soon!) I need to pot up, but I can't stand to put him in more potting soil!

At the same time I don't want to disturb him with a repot while he's growing so fast!

Is there an ideal compromise?

Repot in bigger pot now. The bigger the pot, the bigger the plant you'll have so keep that in mind. Can get as monstrous as you'll let it. A container will control size so choose accordingly

So you do mean"repot" as in remove all soil? I'm with you, get the shock over with now because its not going to slow down much into the winter... I'll be gentle, quick and keep the roots damp while I work... tomorrow since my back is bad atm

Repot as in get bigger pot and some additional potting soil and move plant from present pot to bigger pot. You can add soil from existing pot to the new larger pot.

Thank you. Ok, so "pot up"- I can do that, just hate to see it in crappy potting soil.

Wonder if I can wait for early spring to do a proper repot into quick draining soil, I know its a more appropriate time for the plant but...

Thank you I appreciate the support and guidance- I've been delayed, haven't done anything yet- it is growing VIGOROUSLY, every day and even through the day I see height, foliage size, new leaves, roots growing... just took a peek at the roots and I'm thinking I may need to do something to a couple (1st pic- root circling top) so they don't cause trouble between now and June, and also, I'm really really fighting the urge to repot hahaha

Bossy, there's a difference between a repot and potting up.

Repot inlcudes removing all old soil.

Potting up means you would just remove the plant with soil intact, place in a slightly larger pot and will the sides and bottom with fresh soil.

That said, OP, listen to Al.

I meant repot as in take from 1 pot and place in another pot. Redo potting. And btw I don't waste the original soil, I add it to new pot. I know how to take care of my plants so seldom worried about contaminated soil. could this be regional variance? I've not heard of "potting down" so when u REPOT in my neck of the woods its means change container whether to larger, smaller, with completely new soil or old+new.

I see where a distinction is made between repot and pot up, as explained here. Maybe I'll remember it

Re-pot vs Pot Up

Did you know that plants don’t necessarily have to be moved into new containers to reep the benefit of a spring re-potting? Actually, if you’re going to graduate your plant to a roomier vessel, you’ll be “potting up” your friend, rather than just re-potting. Re-potting your plant into the same container works wonders by refreshing the soil and freeing up root space. Potting up should only be done when your plant has become root bound or overcrowded in its container.

A repot includes root pruning and a change of soil. It ensures the limits imposed by root congestion are relieved. Potting up is simply moving the plant and it's root mass into a larger pot and filling in the space between the pot bottom and walls with fresh soil. This practice ensures the limitations imposted by root congestion remain forever with the plant, unless someone physically gets their hands into the root/soil mass and relieves root congestion via root pruning. Even planting a plant out in the landscape will not relieve the limitations associated with root congestion once the plant has reached the stage wherein the root/soil mass can be lifted from the container intact.

Repotting houseplants in early spring should be avoided because plants are normally at their very weakest after a long winter of short days and adverse conditions, ensuring prolonged recovery periods and unnecessary risk. Repotting very late in the spring or very early summer, around Father's Day or the summer solstice, is MUCH easier on the plant due to the plant's higher energy levels and it's enhanced ability to make food due to longer and more intense photo loads.

Update: 2 days ago- beyond potted up.

(photo is early in the brief process, more soil was removed and more roots loosened)

3 or 4 large roots were already encircling, knotting and growing vertically, I gently teased them loose and was delighted to find the soil falling loose from the root mass. With only a gentle bare handed tickling motion, much of the root mass untangled, and maybe half the soil fell free. I gently played this loose mass into a mixture of approximately 1-1-1 perlite, pumice and potting soil, in a pot approximately 2 sizes up. Roots reached within 4 inches of the bottom, and 3 inches of the sides in any direction. Everything looked healthy, no dark roots. Roots visibly removed/broken were likely 5%-10%.

It got a gentle (slow) pot flush with filtered water.

The cheap potting soil used is marked as "with fertilizer" but I have never seen CRF and plants I have put in it have gotten hungry fast.

The plant went in well fed on FP a couple weeks and was growing strong.

2 days later he's enjoying very diffuse sun or bright shade, showing continued growth and no discoloration. He sits outside (cloudy or shade) when temperatures are equal to indoor. He got a little rain shower today :D

Yay Monstera! Go! Go!

Pics coming

How's your beautiful monster? ;)
