  • When growing perennials, extra care should be give to preparing the soil. Incorporate organic matter in the beginning is the soil is lacking in this regard. Amending the soil prior to the first planting will be the easiest time to do so. Amendments must be done piece meal thereafter as small areas of the bed are dug an replanted.Pay attention to mature size of perennials. When the label says that a particular hosta will spread to 3 feet in diameter, believe the label and plant accordingly. Crowded perennials will decline and produce fewer and smaller flowers and stunted growth.When planting and transplanting pay attention to depth. Plant perennials according to label directions or at the same depth as they were previously growing.The fertilizer recommendation give the amount of fertilizer to apply per 100 sq. ft. and this amount should be split into 2 spring applications about 6 weeks apart. Perennials should not be fertilized after about mid summer since late fertilization will encourage new growth in late summer and fall when most plants should be slowing down to enter dormancy.l
  • Things to consider when placing perennials in the landscape.Height, be sure that larger plants are placed toward the back of the bed while smaller ones are used in the front.Choose color combinations wisely. Remember that blues tend to add depth to a planting while bold colors tend to jump out.Unlike annuals, perennials often have a specific season of bloom, some may only bloom for a few weeks during spring, summer, or fall. Make wise choices to ensure that something will always be in bloom if that is your objective.But don’t look only at flowers, some perennials are grown only for their foliage and contrasts in foliage textures and colors can be just as important as coordinating flower color.

    2. 2. Brought to you by:<br />
    3. 3. What is a Perennial?<br /> A plant that lives for three or more years<br />Usually herbaceous<br />Flower for a shorter period than annuals<br />Whether it’s a perennial, wildflower or weed depends on us<br />Tops generally die back<br />Average a three week bloom<br />
    4. 4. Perennials v. Annuals<br />Pros<br />Variety of plants, blooms and foliage<br />Don’t plant every year= less expensive<br />Ability to specialize in plant groups<br />More challenging to combine well<br />Cons<br />Divide every 3-5 years<br />Short bloom period<br />Less striking blooms<br />Too many choices=design over time<br />
    5. 5. Things to think about when choosing perennials:<br />Soils<br />Light<br />Spacing<br />Hardiness<br />
