To say it was a challenging summer for gardening is an understatement. Yet despite the record-breaking weather, we can claim some modest victories for the OMNI garden.
Up until mid-July we harvested a few tomatoes, and quite a few cucumbers and squash. All summer long--and up to the present--the sweet potato vines have stayed very green (see photos). So, if hotter summers are here to stay, plant more sweet potatoes! Of course, they haven't been harvested yet, so when we dig them up in a few weeks we may be disappointed, but at least the above-ground part has stayed pretty. They also benefited from partial late-afternoon shade.
One other victory was the battle against Bermuda grass. It looks like we have gained the upper hand. We painfully combed through every square inch of soil in the spring and removed big bunches of rhizomes. We did miss a few, but pulling up the survivors once or twice a month has been effective. So, if we stay vigilant, it looks like we can keep them under control. A secondary strategy was to dig a small trench around the perimeter of the garden, and about twice a month chop off any creeping Bermuda grass stolons/rhizomes creeping into the garden (see photos).
We'll probably put the garden to sleep here in a couple of weeks by planting a cover crop (Austrian Winter Pea) and hope for a better year next year.
