Perennials Hibernate, Too!

Of all the seasons, winter has always been the toughest on our garden plants, since the elements become too harsh for tender plants to survive. When warmer temps plummet into near freezing numbers we find it’s best to prepare our landscape for the season ahead. Among our entire landscape, our perennial flower beds need the most attention.

As we know, perennial flowers are those that bloom year after year, making them a vital component of any landscape. Since perennials retreat underground during winter months, now is the perfect time to prepare the soil around them (carefully.) Putting our perennial flower beds to sleep is pretty much like hibernation for these plants. They lie dormant all winter, gathering nutrition and moisture from amended soil. Warmer spring soil allows them to burst forth, stronger and healthier than ever after a long winter’s nap.

Here is a step-by-step guide to putting your perennial flower beds to sleep:

Cut back all the flowers to the ground. Flowers, stems, leaves, cut everything you see down to ground level. Remember that these types of plants are tubers and bulbs. That’s why they stay alive even if everything visible is cut back; the heart of the plant is alive underground. We like to mark each plant/bulb with Popsicle sticks or (upside down) plastic spoons. This way, we won’t plant on top of existing bulbs in the spring.

Remove the mulch and weed your flower bed. Once you’re done cutting everything, it is time to get busy weeding. First, scrape off all the mulch on the flower bed then pull out all the weeds. Make sure you weed thoroughly, pulling out the roots of the weeds to make sure they don’t come back.

Aerate your flower beds. This doesn’t mean that you have to dig holes in the flower bed. You simply have to stick a pitchfork or small garden spade into the ground and wiggle it a bit. This will loosen your soil, making it easier for the nutrients to reach the roots. Just be careful, you wouldn’t want to hit any existing tubers or bulbs.

Now, spread a thick layer of compost evenly over the entire flower bed. Compost is very important because it adds vital nutrients and oxygen to soil, increasing soil organic matter and water holding capacity. Compost also serves as your flower bed’s protection against the harsh elements that winter may bring. When you spread your compost, make sure that you spread a very thick layer (3”- 4”) over the entire flower bed.

Depending on your location, the layer of compost may be all the protection your soil and bulbs require. If you choose, you may place mulch on your flower bed for some added protection. Once the compost has been spread, just add a fresh new layer of mulch. This will protect your perennials throughout the winter, allowing them to sleep comfortably during the cooler weather.

Follow these simple steps and come spring, you'll begin to see signs of color. Before long your perennials will be back, stronger and more beautiful than the year before!
