Spring Gardening Checklist

Checkbox-imagePLANT COLOR

An ideal time to plant colorful, summer-blooming shrubs like spirea, hydrangea and easy-care shrub roses. We also swear by Fertilome Root Stimulator and Elements, on organic Fertilizer.


With a pot trellis, containers turn colorful vining plants like mandevilla, moonflower, black-eyed susan vine or morning glories into vertical art.


Schedule a Snapshot Gardening Consultation at the garden center to get you going in the right direction. Find out more. Perfect for DIYers and created for small spaces.


Pinch off dying/dead flowers to make room for new ones and help things along with Jack’s Petunia Feed.

Checkbox-imagePRUNE LIKE A PRO

The perfect time to prune early spring flowering trees and shrubs like lilacs (once their flowers have faded or fallen). Find the imaginary center of the shrub or tree, then visualize the general shape that builds around it. You don’t have to be perfect, just trim any wayward branches right above one or more healthy leaf buds.
