Poinsettia Do’s and Don’ts

Poinsettia Do’s and Don’ts

Poinsettias are one of the most popular plants during the Holiday Season. Poinsettias grow as shrubs in their native southern Mexico but have been bred to become compact, bushy plants perfect as container ornamentals. The showy “flowers” of poinsettias are actually modified leaves called bracts. Usually red in color, modern poinsettia breeding created showy bracts ranging in color from red to pink to white to orange, with lots of variegations and different leaf coloration patterns and sizes. The true flowers on poinsettias are the small green and yellow parts located in the center of each group of bracts.

Here are some do’s and don’ts to ensure that your poinsettias stay beautiful through the holidays and beyond:

  • Do choose plants with true flowers that are greenish. Plants with unopened or newly opened flowers will last longer than those already sporting true flowers dusted with yellow pollen.
  • Do choose plants that are bushy and leafy. Plants that have lost their lower leaves usually indicate the plant was mishandled and may decline quickly.
  • Do place poinsettias in an area with bright light but not direct sunlight.
  • Do keep poinsettias away from children and pets. Poinsettias are not poisonous but still might cause skin irritation and upset stomachs. People allergic to latex should be aware poinsettia sap contains latex-like materials.
  • Don’t overwater poinsettias. Only water poinsettias when the top of the soil is dry, and let excess water drain away. Remove the poinsettia from the decorative foil wrapping to allow water to drain out.
  • Don’t expose poinsettias to temperature extremes or drafty areas. Poinsettias like the same temperatures as people, so keep them away from cold (temperatures below 50) or heat (temperatures above 80).

After the holidays are over, you can plant poinsettias outdoors. For more information see:

Evergreens for Holiday Decorating

Evergreens for Holiday Decorating

Now that we’ve all been stuffed like a Thanksgiving turkey, it’s time to transition into the final and, arguably, most ornate holidays of the year. Right now you can hear your mantles and door frames crying out to be adorned. Your windows are begging for wreaths and giant red bows. And there may be a certain corner in your house that has been waiting all year for an evergreen, or two.

As we delve into the winter holidays our homes are being dressed to impress. There is nothing better than fresh foliage placed along a mantle or maybe a little mistletoe hanging from a previously unadorned beam. The scent of pine is in the air and I don’t know about you, but I’m ready to get decorating.

Here is a list of a few evergreen plants that make wonderful decorations for the season. You may even find some in your own backyard! Just make sure when you are removing foliage and fruit that you do it gently, so as not to harm the plant. Make all cuts at a 45 degree angle so that water will not pool on branch tips and rot. Also, if you forcefully remove foliage from a plant you could expose the susceptible cambium layer.

Traditional

Magnolia (Magnolia grandiflora) – This southern staple provides foliage that will liven up any banister or door frame. After being cut from the tree it can withstand the dryer temperatures indoors for days on end. 

Hollies (Ilex spp.) – Hollies not only provide glossy green foliage, but bright red fruit that will beautifully adorn holiday arrangements and centerpieces. 

Pine/Pinecones (Pinus spp.) – Pine trees offer a wispy presence to many decorations and their cones can give structure to wreaths and mantle pieces. 

Boxwood (Buxus spp.) – Boxwoods are great for a touch of green.

New Ideas

Abelia (Abelia x grandiflora) (evergreen to semi-evergreen) – Abelia are not commonly thought of when making holiday arrangements, but the texture of their foliage and the myriad of colors can spice up traditional decorations. 

Aucuba (Aucuba japonica) – Aucuba offer a coarse texture that would pair well with the wispier pine foliage. Also, the gold dust variety will add a little more color to the mix.

Aspidistra (Aspidistra elatior) – Aspidistra foliage tends to feel more tropical. If you want to try a non-traditional arrangement these would work well and they can last for days provided a small amount of water. 

Aspidistra foliage that could easily be worked into a stunning arrangement.

Remember that a few well placed planters can liven up even the smallest spaces. Try using a small evergreen tree or shrub such as a magnolia, cypress / false cypress or arborvitae and surround them with poinsettia or pansies. You can try a smaller planter and add in pine cones, poinsettia, grasses, etc. Also if you are celebrating this holiday season with a live Christmas tree, then don’t be afraid to ask the grower/retail center for discarded branches. These can easily be formed into a wreath or used throughout the house. And since this is Florida there’s always the option of decorating your palm tree!

The poinsettia is a beautiful plant associated with the Christmas holidays. These plants create colorful holiday decorations for any home. After the holidays are over, they can be used as landscape plants.

Poinsettias are non-poisonous and non-toxic. However, some people may be sensitive to the latex in poinsettia sap. Although eating even a large number of leaves will not result in illness, the plant is not considered edible. When used as an indoor plant, it should be kept out of reach of children and pets.

Keep your poinsettias away from drafts and chilly air. Water your poinsettia when the surface of the soil is dry to the touch. Place a saucer under the pot, and drain the saucer if water starts to collect in it. Keep the soil from getting soggy. Gently spray the plants with a mist sprayer or place them on gravel trays. Slightly humid air will help prolong the plants’ color and life span. Do not fertilize your indoor poinsettias until you are ready to move them outside. High levels of fertilizer will reduce the quality of the plant.

When the temperatures start to warm up in spring, trim the fading bracts. Leave 4 to 6 inches of the stem on each branch. Begin using a well-balanced fertilizer, and move the plant outdoors to a somewhat shaded area. Once the poinsettia has acclimated to the outdoors, plant it in an area that receives full sun most of the day. Keep in mind that to put out its colorful bracts, poinsettias require 14 hours of complete darkness each day for 6 to 8 weeks. Any interruption to this dark period can delay or prevent the plant from flowering.

Keep the soil moderately moist at all times. Poinsettias grow best in moist, well drained, fertile soils. The ideal soil pH range is 5.5 to 6.5, but the plants will tolerate a range from 5.0 and 7.0. Fertilize your outdoor poinsettias once a month. In north Florida, the plants should be fertilized between May and September.

In the landscape, prune your poinsettias in early spring after they are finished blooming, and when the danger of frost has passed. Cut them back to within 12 to 18 inches of the ground. If the plants have been frozen below this point, cut them back to the live wood. Pruning during the growing season will produce a compact plant at flowering time. After four weeks or when the new growth is 12 inches long, cut the plant back, leaving four leaves on each shoot.

Plants Poisonous to Pets

Plants Poisonous to Pets

Is your pet one of those that likes to nibble on or gobble down new plants in your home or landscape? If so, it would be wise to make sure that the new plants you introduce do not send you running with your pet to the vet. There are many common plants that can adversely affect the health of your cat or dog. Symptoms range from mild nausea and vomiting to death, depending on the plant species and the amount ingested.

Vacation Care for Plants

Vacation Care for Plants

Summertime is vacation time for people, not plants! While getting ready for that long awaited trip, it’s easy to forget about your lawn, landscape, vegetable garden and house plants. A little time spent preparing your leafy friends for your absence could save you needless worry and hours of extra work when you get back.

A vacation may be relaxing and rejuvenating for you and your family, but it can be hazardous, even deadly, for your plants. Unless you make adequate preparations before leaving, you could return to vegetable disaster.

One of the first things you might do before leaving home is ask a neighbor to check your plants periodically while you’re gone. All plants need some care. During an extended vacation container grown plants require special attention and different species have different needs. Be sure you give your friend specific instructions for the care of each type.

If you can’t find someone to personally look after your plants while you’re away, there’s plenty you can do prior to departure to make sure you don’t come home to a limp landscape and sickly house plants. Outdoor container plants should be placed in a shady area to conserve moisture. Under a tree or on the north side of a building are good locations. A thick layer of mulch will help conserve moisture for landscape plantings. Mow your lawn just before leaving, cutting the grass a little closer than usual. An unkept lawn can encourage disease, and it’s a tell-tale sign that no one’s home.

Give lawn and landscape plants a heavy watering – especially recently planted beds, which will need extra moisture. Also, thoroughly spray or dust your plants to protect them from insects and diseases while you’re away. If you have flowering annuals, cut the blossoms before departing. If you don’t, they’ll soon stop blooming. Harvest all ripe or nearly ripe fruits and vegetables. Like flowers, they will continue to produce only if they’re picked frequently. Otherwise, they’ll go to seed.

Do a thorough job of weeding. If weeds are allowed to go to seed while you’re away, you can expect to encounter much more difficult problems later in the season – even next year – when the seeds sprout. Weeding eliminates a major source of competition for your landscape plants’ food and water which may be in short supply during your absence.

Plants kept indoors require special consideration. Before leaving home, place your house plants in a room which receives indirect sunlight. Direct exposure to the sun will dry the soil too quickly. Of course, you don’t want to put your plants in a room that’s too dark, either. Too little light will almost always result in leaf drop. And, just before you depart, be sure to water your house plants thoroughly. This is especially vital, because – unlike lawn grass and landscape ornamentals – house plants cannot benefit from any rain that may fall while you’re gone.

You’ll enjoy your vacation more by making sure your plants are well prepared for your absence.
Gardening in Containers

Gardening in Containers

In a world of limited time and space, container gardens seem to make more and more sense. Poor soil and no place to put plants in the ground are no longer good excuses for not being able to enjoy the simple pleasures of gardening. Container gardening allows the individual to create gardens to fit any situation. Gardening in containers can be just as rewarding as having a full-size garden.

There are a few items to consider when you are planning your container garden. The first is the plants you intend to use. If you are planting more than one plant in the same pot be sure that all your plants meet the same requirements. The requirements you should consider are amount of light, amount of water, climate and fertilizing needs. Some other things you might want to think about when planning your container garden are height, color, and texture. A nice variation of these elements will make your container gardens more attractive and increasingly more interesting to look at.

The next step in container gardening is choosing your container. A good rule of thumb is: “Anything that holds soil and has drainage holes in the bottom may be transformed into a container garden.” It can be a pot you purchased from the local gardening center or an old bathtub you picked up off the side of the road. However, be sure that the size of the container matches the current and potential size of your plant. For vibrant plant growth, the containers must provide adequate space for roots and soil media, allowing the plant to thrive.

Colorful containers bring life to your small spaces.

Colorful containers bring life to your small spaces.

Next on your list is choosing a soil for your container. Container soils need have good aeration and decent drainage, while still being able to retain enough moisture and nutrients for plant growth. When choosing what to use in containers, never use garden soil by itself. When garden soil is added to a container, both drainage and aeration are severely impeded, and the results are plants that grow poorly or not at all.

Container soils are often referred to as soilless or artificial media, because they literally contain no soil. They are commonly composed of various media such as peat moss, perlite, vermiculite, bark and coir fiber (ground coconut hulls) in a variety of mixes. When using soilless media remember t0 moisten it slightly before planting. Fill a tub with the media, add water and lightly fluff the media to dampen it. This will keep the mixture from becoming hydrophobic (unable to take up water) throughout its life in the container. When adding media to your containers, never fill the pot to the top. You should leave about a one-inch space between the top of the soil and rim of the pot. This will make watering the pot easier as it provides a place to “put water” and not have it run over the edge.

When watering your container gardens, the best time to do so is in the morning. Watering in the morning allows the leaves of your plants and soil to dry out, preventing diseases and viruses. Remember that overwatering is the most common reason for fatalities in container gardens. Check your soil by pushing your finger into the media; if the media is moist don’t water it. When it comes to fertilizing your container gardens, fertilize only as needed. Over-fertilization will result in a buildup of salts and may burn the roots of your plants. Try to fertilize your plants during the growing season, and only if needed during the dormant seasons.

The most important objective when container gardening is to be creative. Maybe, try a variety of plants in one container garden. While an nicely put together individual container can be quite impressive, think what might happen if you put several containers together in a group. Also, don’t limit your container gardens to flowers–many vegetables can be grown in a container and actually do quite well. There really is no limit to what can be done in a container!
