Though most perennials may take a couple of years to flower from seed, many are as easily started as annuals. The quickest way to have blooming plants, however, is by vegetative propagation, such as by dividing old plants or rooting stem cuttings. Plants produced vegetatively have all of the traits of the "mother" plant. Propagation by division may seem difficult at first, but most gardeners find that dividing crowns and roots and separating bulbs takes very little experience and can be mastered quickly. Try dividing monkey grass for experience; then move on to daylilies, and before long you will have the hang of it.
Perennial plants with shallow roots are easily pulled apart by hand. Long fibrous roots can be pulled apart with a hand fork. Thickly intertwined roots may need more forceful separation or cutting with digging forks. Replant only those segments with strong roots and a few intact leaves or crowns.
In general, it is best to divide perennials during their dormant or "off" season; divide spring bloomers in the fall and fall bloomers in spring. Some perennials may need dividing every 3 or 4 years, or they will slowly crowd themselves into clumps of nonflowering leaves and roots.
Many perennial plants may be propagated from stem cuttings, which does not disturb the plant's roots. Take stem cuttings during the spring or early summer, choosing stems that are mature and firm but not yet hardened and woody. Cut off 4- to 6-inch segments using a sharp knife or shears, and pinch off the succulent tip and any flower buds to force the cuttings to concentrate their energy on producing roots. Remove the lower leaves that will be below the surface of the rooting medium, but leave a few leaves to provide a source of energy for root initiation and growth.
Because of disease or weather conditions, cuttings often will not root directly in garden soils. They may be easily started in a pot containing a porous, well-drained rooting medium, such as a 1:1 mixture of perlite and peat moss. Coarse sand and vermiculite are also used as rooting soils. These mixtures will hold moisture and yet allow drainage for air circulation. Root-stimulating compounds, including those that contain fungicides, are available at most garden centers. Using a blunt stick, pencil, or finger, open a hole in the rooting medium and insert the treated cutting. Firm the medium around the cutting and water in well.
Many commercial growers use a mist bed to keep cuttings from wilting, but this is usually not feasible on a small scale. You may easily construct a humidity tent from plastic film loosely draped over a frame covering the cuttings. Place the tent in bright light, but prevent overheating by making sure the tent is not located in direct sunshine. Keep the plastic loose to allow air circulation. Avoid direct contact between the leaves and the plastic. The tent will serve as a tiny greenhouse and will maintain a good rooting environment with daily light watering. Rooting often occurs within 3 or 4 weeks. By the time new leaves begin to appear on cuttings, roots are usually formed. Remove the plastic tent and water regularly until plants are firmly established.
Transplant newly rooted plants into prepared beds or pots and place in a bright, protected area until you are ready to set them into your garden or share them with others.
Late summer and early fall are among my favorite times of the year because the ornamental peppers are starting to really color up.
More and more fellow gardeners are jumping on the bandwagon and planting these beauties in their landscapes. These plants are hot -- in landscape character and accent -- and they carry the garden through the fall season and maybe beyond.
Most ornamental peppers begin setting fruit as the temperatures rise, so the best show is always saved for late summer and continues through the fall as they keep producing. This means you need to set these plants out in the late spring.
This is the time of year many gardeners have been waiting for all summer.
If you’re thinking about the cool front that blew through this past weekend, I’m afraid you’re incorrect. What I’m talking about is the emergence of naked ladies in gardens all across Mississippi.
I’m talking about the seemingly magical plants known botanically as Lycoris. Common names include magic, surprise or resurrection lily, but some gardeners simply call them nekkid ladies.
CRYSTAL SPRINGS, Miss. -- Home gardeners and horticulture professionals can learn about the latest plants, research and gardening techniques during the 39th annual Fall Flower & Garden Fest on Oct. 13 and 14.
This year has been a challenge in my home landscape and garden.
First, we have had a lot of rain: more than 93 inches and counting collected in our Community Collaborative Rain, Hail & Snow Network rain gauge. If you’re interested in being a volunteer rain reporter for them, go to http://www.cocoraahs.org for more information. I’ve seen so many waterlogged landscape beds and lawns that just won’t dry out.
The second big challenge was the heat. When it’s not raining, the high temperatures and humidity have maintained heat indexes that make me -- and many others gardeners -- just stay indoors. Surely that yard work can be put off until October.
But I’ve taken the steps to make my gardening an easier chore
