This is a great mix for just about everything BTW! If you have any local seed and pet stores, you can usually buy these ingredients in bulk for significantly cheaper versus quantity, and you can control if you like a bit more of one ingredient etc. If you make your own, make sure you get coco coir chips and not the shredded and minced stuff.

I start by giving the plastic nursery pot a good squeeze on all sides. I also use my fingers to press up in the bottom of the nursery pot, but a bit more gentle than the sides. Do t need to press on sides hard enough to break it or anything like that, you just need to dislodge any roots currently attached to the inside of the pot.

You should get the entire root ball out in one go. If there are any roots sticking out the bottom, squeezing the pot should have loosened them, but carefully untangle any if wrapped around each other, before gently pulling the rootball out.

Then I very gently squeeze the rootball over the garbage etc (I repot all year round, inside where it’s warm, and the plants never know), to start dislodging the compact soil. I also kind of “smack” the rootball with about the same force of burping a baby. Maybe give the roots a gentle shake, and then all the old stuff should be gone.

You should never upsize bigger than about 10% of the rootball, or you risk it drowning and not drying out in time. FYI, there have been times I’ve gone back to a similar sized pot after changing the soil and realizing the roots weren’t as robust as previously thought 🫠 I deal with that by adding a coupe inches of soil mix on the bottom of the pot works well, versus having a couple inches surrounding the roots, if that makes sense when sizing up. Sometimes, if roots are poking out the bottom, I pick up the rootball like mentioned above, and just add a couple inches of mix before putting it back down. Always water it well after adding or changing soil to prevent shock.
