Perennial planting, care and maintenance
Set perennial plants in their permanent places so their roots are completely covered with prepared soil, but avoid burying the stem or crown. Place container-grown plants the same depth that they were grown; place dormant plants at the depth at which they grew the previous season. To encourage side root growth, make a planting hole twice as wide as deep. With bare-root perennials, spread the roots outward as well as downward. For container-grown plants, loosen encircled roots and shake some of the potting soil into the planting hole. Remember to crumble away the top edges of a peat pot to prevent water loss through wicking. Do not let roots dry out, especially during transplanting.
Water the plants thoroughly to force out any air pockets and to settle the soil. Mark and label the plantings. Mulch the bed surface with pine straw or bark to keep soil from drying, crusting, and overheating in the summer, and to prevent many weed seeds from germinating.
Care and Maintenance
If you do not mulch your plants, use shallow cultivation in the spring and early summer to break and aerate compacted soils. This also aids in water penetration and makes it easier to incorporate fertilizer. Summer cultivation can damage shallow roots and is more difficult because the plants will be larger. Early in the season, stake tall plants with wire stands or bamboo canes. Use care to avoid root damage.
Apply fertilizers sparingly to plants early in their growing season, after new growth begins to show. If plants are growing well, no additional fertilizer may be needed; otherwise, a second light feeding will be helpful several weeks into the season.
In the fall, cut the old plant stalks to the ground after the leaves have fallen and mulch to protect crowns and roots from the harsh extremes of our mild weather followed by sudden cold spells. Remove any winter annual weeds that may have germinated before applying mulch. Fall is also a good time to divide many plants that may be encroaching on one another.
It’s starting to get hot out there, y’all! Don’t let the Mississippi heat deter you from taking good care of your garden and landscape.
Many of the garden center stars that draw the most attention are plants with big, flashy flowers. But there’s a group of plants that can have just as much landscape value: plants with tiny flowers.
One of the landscape views many gardeners ignore is the horizontal plane. Plants that create mats or carpets create a lot of interest and serve an important role in landscapes and gardens.
Let’s look at a few of my colorful carpet favorites.
I’m becoming increasingly optimistic about our 2020 Mississippi summer gardens and landscapes. COVID-19 is on everyone’s mind, but an upside to the virus is that more homeowners are gardening than ever before. If you’re looking for summer color that will grow through the summer and beyond, then Profusion zinnia is the plant for you.
