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.
If you read this Southern Gardening column frequently, you realize that I grow much more than pretty flowers in my home garden. Besides ornamental plants, I love to grow vegetables that my wife and I can enjoy for dinner.
Salvia is one of the groups of plants that everyone should have in their landscape. This plant group has flowers with a wide-ranging color palette and different sizes. Salvias are loved -- by me especially -- because of their ability to attract pollinators, butterflies and hummingbirds.
If you’re anything like me, I find any excuse to get outside. The warmer temperatures and colorful blooms are refreshing, especially after the cold winter we had! Working on outdoor chores is a great excuse to get some fresh air. Here are a few tasks you need to cross off your checklist during April:
Some of my favorite late-summer annuals are the ornamental peppers. These tough plants have to survive the heat and humidity of our Mississippi summers before they become the stars of my summer landscape.
We had another great weather weekend in the garden, and I spent a couple of days catching up on getting my Urban Nano Farm ready for spring. I’m almost finished repairing my fence after it was redesigned by Hurricane Zeta last year
