What, if anything, can be done to mitigate the effects of my already tilling last year's Clopyralid-tainted compost into my garden? Will the stuff ever degrade? What will it do to the $50 worth of bulbs I just planted in that bed?
"Tulips are one genus in the family 'Liliaceae' and not considered a susceptible plant to Clopyralid damage," said Mollie Mangerich, operations supervisor at Lawrence's Waste Reduction and Recycling Division.
Plants most susceptible to Clopyralid include potatoes, tomatoes, peppers, peas, beans, petunias and sunflowers.
Mangerich said most of last year's Clopyralid should be gone by next year's growing season.
"Research varies on the length of time that Clopyralid degrades, varying from the average of one to two months and ranges up to one year, dependent on soil type, climate and moisture in the soil," she said.
