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.
The last two weeks, I’ve told you about two of my top three cool-season flowering bedding plants. Today, I’m going to complete the trifecta with another plant everyone should have in their landscape: the viola.
Violas may have smaller flowers than their cousin, the pansy, but they’re maybe even tougher and more tolerant of cold, winter weather than pansies. These plants are beautiful massed in landscape beds, and they can be great performers all the way to Easter.
Even though the air is still warm in many parts of Mississippi, it’s time to plant annual winter color. Last week, I wrote about pansies being a great color choice. Another sure-fire pick is dianthus.
These days, I have to wear my hoodie sweatshirts and long pants for anything below 60 degrees. But the falling temperatures also signal something great: racks and racks of great, cool-season color as pansies fill local garden centers.
This year, I’m getting an early start on my ornamental kale and cabbage planting for the fall.
A couple of weeks ago, I found these plants being marketed in variety packs, so I picked up a selection of kale and cabbage. What an easy way to select plants for your landscape this weekend.
Confederate rose is sometimes called Cotton rose and Cotton rosemallow. Despite the references to cotton, this plant is actually a hibiscus that originated in Asia.
