No Nitrogen Fertilizer
No more nitrogen containing fertilizers for your roses. Instead fertilize with potassium/potash to help your roses harden off for winter. Alaska Morbloom is a good, easy source of potassium.
Japanese Beetles
Japanese Beetles have arrived in the Twin Cities. For quick knock down use Spinosad or Carbaryl. For longer term effect try deltamethrin or bifenthrin. To kill grubs apply a good grub killer to your lawn between July 15th and Aug 1st. For best results dethatch lawn first then water grub killer in after application.
Upcoming Arboretum Activities
It’s time for the 2017 work dates at the Wilson Rose Garden at the Minnesota Landscape Arboretum!
