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.
Home gardeners in Mississippi need colorful plants that hold up to the hot conditions we have every year. One group of plants that is a great choice for summer color is salvia, which includes both perennial and annual top performers.
The annual Salvia Splendens, as the name suggests, can't be beat. It is commonly called scarlet salvia, but it comes in a variety of bright colors.
BEAUMONT, Miss. -- For 16 years, Christine Coker has been doing what she loves: putting food on people's tables.
"In college, I really liked the study of plants, but I knew I wasn't going to be the world's greatest botanist," she said. "What I really wanted to do was feed people."
I really like to the flowering annual purslane in our hot summer landscapes. It's a vigorous, low-growing plant that forms a colorful carpet with succulent foliage.
But I plan to write about that wonderful plant in the future. Today, I want to extoll the virtues of one of its cousins: moss rose.
Moss rose has fleshy, succulent foliage that helps it hold up to the summer heat. The 1-inch-long, cylindrical foliage is bright green and arranged in clusters on the stems.
VICKSBURG, Miss. -- The Southern Gardener, Gary Bachman, would like to see Mississippi's historic bed and breakfast owners step up their game in the garden.
"What is your budget for your landscape and labor costs? Do you serve anything you grow and use your own flowers?" Bachman asked owners at a recent Mississippi State University Extension Service workshop. "I want to show you how, with minimal effort and minimal out-of-pocket expense, you can get a good return on investment from the landscape of your historic properties."
With summer officially here and hot and humid weather firmly in place, many gardeners -- myself included -- like to look at a pretty landscape, but don't really want to get out and do much work in that same landscape.
So selecting plants that look good without much work pique my interest. One plant that doesn't disappoint me is Sun coleus.
