defoliated pussy willow from caterpillars

Anonymous added on June 4, 2015 | Answered

Last summer we planted a weeping pussy willow. This year it bloomed nicely but within the last 24 hours it has been attacked by a swarm of black and orange caterpillars who have literally defoliated the tree. What should we do? Will the leaves grow back when the caterpillars leave (if they leave)? Will this spread to the rest of my garden?

Products containing Bacillus thuringiensis (like Safer or Bonide) will help and are readily available at most garden centers and plant retailers. Here is more information on getting rid of caterpillars: https://www.gardeningknowhow.com/plant-problems/pests/insects/prevent-caterpillars.htm
