2020 Plant Health Forecast

Last Spring/Summer

• Cold & Wet Spring, created ideal conditions for fungi in the summer months – Mainly Anthracnose & Fire Blight
• Lots of defoliating pests last summer – Aphids, Japanese Beetle, Fall Webworm, Caterpillars

• Predicting a wet and cold March
• April and May are predicted to be warmer and rainier than normal
• Summer is supposed to also be hotter and rainier than normal, so high humidity levels are expected.

This will create the perfect conditions for fungus and insects to thrive!

• Oak wilt – causes the rapid decline and death of mature oak trees
• Box tree moth – Can strip ALL foliage from your boxwood in 1 day

• Make sure your tree has the tools it needs to bounce back from fungal and defoliator stress with Cohen & Master’s ArborGain™ treatments

• Get your pest treatments planned early – if you had caterpillars or aphids last year, have your arborist out in early spring to do an inspection of your trees

• Make sure your soils are draining properly to accommodate increased precipitation – have your soils renovated with our air spade tool and ask your arborist about soil aeration tubes to improve drainage around your tree’s roots
