I was gifted a large syngonium at an estate sale over the weekend, and it's in a lovely, globe-shaped pot. However, the roots are packed so tightly that I am afraid of tearing up the plant or breaking the pot to get it out. I thought about using a hose to wash away some dirt, I'm pretty sure it hasn't been repotted in at least 10 years, so new soil would be good; the current soil is incredibly compacted and hard as a rock; even the hose didn't move enough soil to soften up the root ball so I could section it.
Any ideas? It's a lovely hand-thrown pot, and a lovely plant that I don't want to kill, but it desperately needs Al's soil mix and a larger pot.
