Fertilizing outdoor plants in spring
I live in Portland, OR, and was wondering when I can fertilize my outdoor perennials in the spring. Is April 13th too early? Thank you!

The best time to fertilize outdoor perennials is when they start to put out new growth in spring, so for most plants that's now. That way they have all the nutrients they need for the spring flush of growth. By the way the worst time to fertilize most plants is late summer when they will put out lush new growth that will be vulnerable to winter damage.
