I pulled out some underperforming cucumbers and saw the telltale knobby roots of a nematode infestation. Nematodes are microscopic worm-like organisms that feast on your plant’s roots, inhibiting their ability to uptake nutrients and water. Above-ground symptoms include yellowing of leaves, stunted growth, loss of vigorous growth and lack of yield.
My plan is to solarize the garden by covering the soil with plastic for about a month and letting the sun superheat the soil. It has the added benefit of killing lingering weed seeds. I will also make sure to plant some chrysanthemums and marigolds to repel any re-infestation.
Hopefully our fall crop will make it… because I love brassicas.
