Gardening Question of the Day for Friday, December 14, 2007
I have a healthy gardenia in a pot. The plant is well over a year old and has yet to bear flowers. Any ideas as to why? (answer).

Basically it involves the same practice as Vegiforms. Rather than try and get the fruit into the bottle once it's mature, the bottle is placed over the fruit blooms and the fruit grows inside the bottle.
Once the fruit is fully ripened then the bottle can be removed. Then it's just a matter of filling the bottle with your favourite liqueur and storing. And these can be stored for years - the longer the better.

The Path to Enjoy 2009: Sustainability
Sometimes nothing is a better than lip service. Case in point, being the ‘lip zone’ in a plant pot. Hilary Allan, one of our growers, and I were walking through the greenhouses the other day, and she pointed out that she always leaves a two-centimeter, soil-free zone at the top of the Easter lily pots. The reason she does this is so that customers will have just the right size water reservoir to ensure that their lilies get water and their kitchen counters and floors don’t. It may not sound like a big deal, but I think those little details make the difference between thoroughly enjoying a plant and wishing that you hadn’t bought it. I am the first to admit that I can be sloppy with the watering can at home (call it the curse of growing up in the greenhouse where water on the floor wasn’t a big deal), so I’m happy to take all the help I can get.
Hits & Misses
Hit: Popular Plant Arrangements
Indoor plant arrangements are hot items this Christmas, and I think their popularity can be attributed to their simplicity and ease of design. All you really need to create a great arrangement is an attractive pot, some quality potting soil and an assortment of small indoor plants. Add decorative rocks for top-dressing and a tiny ornament, and presto!—a terrific holiday centrepiece is born.

Miss: Tight Spaces
Heat and low light levels are a bad combination for plants. Each year, because of a lack of space, a few plants manage to find their way beneath the hot water pipes in the greenhouse. The problem with that scenario is that the heat encourages the plants to grow, but the light source doesn’t provide enough energy for them to assimilate nutrients. The inevitable result is soft, stretched and weak plants—the kind that usually topple and fold like cheap umbrellas in a wind storm.
Question of the Week
Why are plants green?
My daughter is studying light and lenses in her Grade 4 class and asked me why plants are green. The short answer that I gave her was that plants are green because they hate the colour green. Of course, that’s not exactly the truth, but I was going for drama. What I went on to explain was that while plants don’t hate green, they don’t get a big charge out of it either—literally. Plants prefer to utilize light in the red and blue spectrum and to reflect light in green spectrum. And that reflection of light accounts for why our eyes perceive most leaves as green. So the next time you are admiring the verdant leaves of your favorite shrub, remember that it is doing its best to give it away.
Science & Technology
Potassium Deficiency
Researchers in the department of Horticultural sciences at Texas A&M have determined that Phalaenopsis or moth orchids, as they are commonly called, do very poorly when grown in soils with low levels of potassium. The bottom line is that if you grow this type of orchid in your home, give it regular feedings with fertilizer that has a high last number on the label. A good indicator that your orchid might be a bit low in potassium is when it displays yellowy or bronze lesions on its leaves.

Sustainability
Can art make a greenhouse more energy efficient? Well, maybe it will in our new location. We are working with a glass-blowing studio and various experts in the sustainable energy field to explore the possibility of recapturing the waste heat from the glass blowing furnaces. The heat would be used to warm the water in the greenhouse, and the vases manufactured in the studio would be sold in the Floral Design department. We think the answer is Yes!
