Plant - Stop buying bags of mulch. Plant one of these groundcovers instead and you'll have permanent weed control that actually improves over time... There's a reason professional landscapers use groundcovers in places they never want to maintain. Once these plants establish, they self-perpetuate. They spread, they thicken, they shade out competition. You're not just solving this year's weed problem. You're solving next year's and the year after that. Many learn this the hard way trying to maintain large garden beds without help. Mulch seemed like the answer until they realize they were reapplying it every spring, pulling weeds through it all summer, and watching it wash away in heavy rain. Groundcovers changed everything. They stay put. They multiply. They get better with age instead of breaking down. Creeping Phlox is the perfect example. You plant it once in a sunny spot, and it gives you spectacular spring flowers. But more importantly, that dense foliage stays thick all season. New weeds can't push through. Existing weeds get smothered. And every year, the phlox spreads further. For moisture-loving areas where weeds thrive, Creeping Jenny is nearly unstoppable. That bright chartreuse foliage roots at every node, creating an interconnected network that nothing can penetrate. I've used it to fill wet spots where regular mulch would just float away. Problem solved permanently. Deep shade used to mean constant battle with creeping weeds and exposed soil. Then I started using Hostas as groundcover instead of specimens. Plant them close enough that those big leaves overlap. The soil underneath stays dark and cool. Weed seeds don't germinate. The ones that try get shaded out immediately. Here's what makes groundcovers superior to mulch. Mulch is passive. It sits there doing nothing while weeds probe for weak spots. Groundcovers are active. They grow. They spread. They fill gaps automatically. Every runner that roots down is another square foot you'll never weed again. The setup requires effort. Clear the area completely. Plant closer than the tag recommends. Water consistently that first season. But once they connect and fill in, you're done. That spot maintains itself. You've converted a maintenance problem into a maintenance-free zone. Have you tried using groundcovers for weed control, or are you still fighting with traditional mulch? [snbWv] | Facebook

Summer-Flowering Perennials

Summer-flowering perennials like black-eyed Susans, coneflowers, and daylilies provide continuous color throughout the growing season. Many of these plants are drought-tolerant and low-maintenance, making them ideal for mulch beds.

These perennials attract pollinators like bees, butterflies, and hummingbirds, creating a vibrant, ecologically diverse garden. Group plants with similar water and light requirements together for easy care and optimal growth.

When creating your mulch bed, consider the plant's mature size, growth habit, and care requirements. Layer plants with varying heights, textures, and bloom times to create a dynamic, engaging landscape. Regularly refresh the mulch to maintain its benefits and keep your garden looking its best.

Embrace the journey of designing and maintaining your mulch bed. With the right plants and a little TLC, you'll create a beautiful, functional outdoor space that brings joy and life to your home.
