relative vigor and weed competition
H'man's comment in another thread (which I'm copying below) got me trying to connect some dots with what's going on with my fruit and nut trees.
"It is very difficult for establishing fruit trees to compete with tall weeds- 3 options- frequent cultivation, mulch or herbicide. Keep at least a 4' diameter circle free of grass and weeds at least from early spring into July."
First, a couple questions about keeping down weeds. H'man, you talk about difficulty competing with "tall" weeds, but you don't mention mowing as any kind of option. What's the usefulness and what are the limits of mowing when establishing fruit trees?
As far as cultivation, what are the options there? Does that mean hand weeding? Rototiller? Any other cultivation options? I'd be afraid of the damage I'd do to my tree roots from rototilling.
And what about flame weeding? Would that be another option? Anyone use flame weeders around his trees?
I moved to where I live in the fall of '07 and immediately started planting trees, so after nearly 5 growing seasons I'm starting to notice some big differences between trees in vigor and growth rates, and I'm wondering how many of the slow growers can be explained by my failure to follow H'man's advice above.
Trees that have grown very vigorously for me despite minimal attention to weed/grass competition include:
European and Asian pears (on whatever Hidden Springs uses for rootstock)
European plums (except that I planted them on the N side of a building where there isn't as much grass/weed growth)
Trees that have had growth that seems normal and healthy but that don't seem as vigorous as the group above:
some apples (stayman, limbertwig... M111 stock)
Italian stone pine
Trees that seem healthy but have grown very slowly:
other apples (Arkansas black...)
Meader persimmon (although it seemed to finally catch a good growth spurt last year, year 4, but was hit twice by hard freezes in early and late April this year)
Trees that look stunted:
Gold Rush apple, Liberty apple
or appear healthy but haven't hardly grown any in 5 years:
