Oops. I just looked at the flip side of the crape myrtle growing instruction page, and it says to totally replace the hole dirt with potting soil.
Guess that's what the grower was talking about.
Hmm. I’ll have to think about this. Do I want to dig up the two I planted and redo both those holes? Not necessarily . . . Because I’ve read other authorities on growing shrubs who say that if the soil in your planting hole is too much different than the native soil around it, the roots will never venture into the native soil, they’ll just coil round and round in the fancier dirt you put in. And never really get established.
Only thing that might make me start over is the warning on the crape myrtle instructions not to use heavy sand-based mixes. That’s what I’ve got out there, that’s for sure. I mean, don't I want these babies to have every possible advantage?
On the other hand, can I really afford the luxury of several bags of Miracle-Gro potting soil?
Um, no. Maybe I'll just get some perlite and lighten the mix I’ve got going.
Oh, yes-- for what it’s worth, it’s been running rivers of rain since 8:30 or so. Did not go out in it to see if the leaf mulch is holding. If it's not, there's nothing I can do about it tonight.
