Step 7 · Apply Mulch

Once the flowers are planted and watered, apply a 2-3 inch layer of organic mulch, such as wood chips, shredded bark, or straw, around the base of the plants. Keep the mulch a few inches away from the plant stems to prevent rot and discourage pests. Mulch helps to retain soil moisture, reduce weed growth, and insulate the soil, protecting plant roots from extreme temperatures.
