Yes. The best thing you can do for your tropical indoor alexandras is grow in containers. A good rule of thumb is: grow as many alexandras as you can possibly grow within your living room, and put them under a ceiling-mounted light. Since they grow so well inside, they should thrive just fine out of a container.
Which strains would my alexandras love?
A good question. All are different and they each have their own qualities that they want.
Pumpkin Alyssa: A sweet, almost citrus-floral fragrance, it smells wonderful fresh-smelling or dried. It’s often used in place of other flowers. It’s also used as a very good winter bloomer.
Blue Dream Alyssa: A slightly fruity fragrance with a sweet aroma, but it tends to lose its flavor, so keep it in a cool, dark place. It’s usually picked on the driest or wettest days of the year.
What are the best conditions for growing orchids in your area?
There is some good evidence that the best growing conditions available today are for high latitude, low humidity areas:
In the south of Spain, northern Italy and Greece, a hot dry season with warm daytime temperatures and nights around 30C-36C and low humidity. (A good growing medium for tropical butch is pecans, with the pecans getting extremely moist as humidity levels fall. I’ve had a good deal of success with pecans growing in these conditions.) In France, the summer months in southern France and southern England are typically cool on days of 45-55C with the highest humidity of 90%, and hot (65-85F) on nights.
In eastern Australia, and central and east-central France and northern Italy, the summer months are moderately cool with a mean daytime temperature of 28+C with a mean nighttime temperature of around 28-31C with high humidity (in France, 60% to 80%!). In the warm north, the summer months are hot with a mean daytime temperature of 25
Let us mention that a growing medium may have different nutrients than your soil. You can expect that there would be an effect on the germination of a seedlings (due to the growing medium), and in some plants, you may have to supplement the nutrients too.
In these plants you would be required to feed at the following rates:
1.65kg (3.4oz) or more in total per litre of water
1.5 kg (3.3oz) or more per litre of nutrients, or
0.9 kg (2.5oz) per litre of nutrients in combination with air feeder solution.
When to Plant
If the above recommended levels are satisfied you should consider planting your orchids indoors, as the growing period will shorten significantly once you leave the box for the evening or early morning
