Hi there! I'm a very, very new gardener and have gone a bit overboard with my new pet projects.
I have a Valencia Pride Mango tree (I think "grafted"--whatever that means) that I need to plant in a container ASAP.
Question 1: What is the recommended planter size container? I've heard 15 gallon, but then when I look for pots, they are not labelled by gallon size...rather in diameter.
Question 2: What is the best soil type to fill with. I've heard a lot of "No, no MiracleGro!" so I know to avoid that, but I've also heard that a volcanic-y soil is beneficial.
Thanks in advance! I probably spent too much on this tree as a novice and really, really don't want to kill it!
