Medium for citrus trees in smart pots
Hi all, just bought a Moro blood orange, Improved Meyer Lemon, and Washington Navel orange today from Four Winds. I plan on putting them into 7 gallon Smart Pots for the next couple years and they will be sitting directly on dirt.
I plan on using Foliage Pro for fertilizer, but am having questions about which medium I should be using. Was originally planning on using Al's gritty mix, but I fear that with the drainage and breath-ability of Smart Pots, that the medium will dry out too quickly. I have also read here on Gardenweb that if they are in smart pots and on the ground, the ground will act as a wick, pull moisture away and facilitate good drainage. So therefore, can I use another, more moisture retentive medium like Pro-mix?
Anyone have experience with dwarf citrus in Smart Pots?
