Landscape plantings “spring forward” with a spring application of a simple, well-balanced, slow-release fertilizer. I recommend a granular or spike-form fertilizer rather than water-soluble types; which are mainly for container gardens. When applying your fertilizer, follow the directions on the label. You don’t want to over-fertilize and damage the roots. ONE exception is roses, which do well with monthly applications through mid-summer. By late summer, it’s time to halt all fertilizing activities. If you’re not sure which fertilizer to use, ask a professional at your local garden center. Be prepared to tell them what types of plants you want to fertilize, and they will be able to help select the right product!
Thanks for asking!
