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.

There is a type of plant treasured for its ability to be shared. Known as pass-along plants, these are often shared by gardeners, friends and family, typically through cuttings, divisions or seeds.

These plants carry sentimental value and foster a sense of community, as they are often passed down through generations or exchanged within local gardening groups.

I’ve always been a fan of butterfly bushes, so in my garden, I have both regular-sized varieties and a couple of dwarf varieties.

My favorites are the dwarf ones. They are compact and known for their fragrant blossoms and ability to attract pollinators such as butterflies, bees and hummingbirds.
