Site Selection and soil preparation for perennials
Consider the site before selecting your plants. Although many perennials, such as ferns, tolerate heavy shade, most perennial plants require abundant sunshine. Air circulation is important for avoiding diseases; stagnant, warm, and humid air creates ideal conditions for diseases. Perennial plants also require properly prepared soil, and a few have specific drainage and fertility requirements.
Soil preparation for perennials is similar to soil preparation for annuals. However, you should devote some special attention to perennial bed preparation, because plants may occupy the site for several years with little opportunity to correct any problems. When possible, add sand and organic matter such as bark, peat, or compost to soils well ahead of planting time.
A layer of organic matter 3 or 4 inches deep, worked into the soil a shovel's depth, is usually adequate. Since different types of organic matter work and decompose at different rates in the soil, it is best to use a little of two or three kinds of organic matter than a lot of just one.
Soil testing provides specific recommendations for fertilizer and lime needs. Since lime lasts for several years depending on the type used, never add lime without a soil test. Many fertilizers, such as phosphorus, are best applied and mixed into soils before planting. Perennials need a balance of several nutrients, including nitrogen, phosphorous, and potash; most garden supply stores carry a wide variety of fertilizer mixes. Keep in mind that phosphorus, including that found in bone meal, lasts for several years and need not be applied regularly.
One of my favorite easy-care, flowering plants has to be lantana. This low-maintenance plant is highly tolerant of the hot, humid summers in our Mississippi gardens.
It’s no wonder that lantana has been selected as a Mississippi Medallion winner three times.
Through February, I’m highlighting plants named 2020 Mississippi Medallion winners. Each of these winners is superbly adapted to our garden and landscape environment.
This week, I want to tell you about American beautyberry, a winner that is a native species found across the Southeast. It is known botanically as Callicarpa americana.
A couple of weeks ago, I had the privilege of introducing the 2020 Mississippi Medallion Winners at the Gulf States Hort Expo in Mobile, Alabama. This is a special group of selections, as the Mississippi Medallion program is celebrating its 25th anniversary in 2020.
The plants selected for 2020 include Colorblaze coleus, beautyberry, Luscious Series lantana and Garden Gem tomato.
It may be chilly outside, but don’t let that deter you from going outside and working in your garden and landscape. Grab a jacket and your gardening tools, there is plenty to be done during February!
I don’t think you can go wrong with some dianthus in your landscape in 2020.
I love the flower colors that include pink, red, lavenders, white, and bicolors. The foliage of these plants ranges from being grass-like to broader strap-like linear leaves. Plus, the foliage provides contrast with colors ranging from bright green to steely blue-gray.
There are some great selections that will do a fantastic job in our Mississippi gardens and landscapes especially in the cooler months of the year.
