Creeping Phlox Emerald Blue Plants for Sale Online

It's rare to find such a vigorous source of blue in a ground cover. A notorious dweller on edges of rocky embankments, the Emerald Blue Creeping Phlox is just that. The mass of deep blue flowers and evergreen foliage spreads over curbs and short retaining walls, or amidst rocky outcroppings. This perennial is an ideal cover plant for difficult edges of dry streambeds or rock waterfalls. However, the Emerald Blue Creeping Phlox is equally at home in the front of a traditional flower border or planted along the edges of flagstone walkways.

    Planting Information

    We suggest when planting your newly purchased Emerald Blue Creeping Phlox plants that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Emerald Blue Creeping Phlox does prefer drier soils so if there was ever a plant that we would recommend not adding topsoil or compost this is one. Bio-tone starter fertilizer is a great starter fertilizer that provides plants with mycorrhizae fungus. It is a naturally occurring beneficial fungus that colonizes on the new growing roots of plants. It creates a barrier between the roots of the plant and fungus and pathogens that can cause root rot. We love this product and use it on all plants we install in our own gardens. Bio-tone is a gardener’s best friend and can help guarantee your success.
