Phalaenopsis Ice Cube Trick

First off, there is no “Phalaenopsis Ice Cube Trick.”

Most of the members of the orchid family, the Phalaenopsis included, are tropical plants. This means they don’t know what to do with ice or cold temperatures in general. Please don’t use ice cubes to water your orchid. Instead, water it thoroughly rather than partially, as suggested by the care instructions provided with your orchid. By watering it thoroughly, you’ll approximate the Phalaenopsis’ native environment that normally includes heavy rain showers.

The trick about watering Phalaenopsis orchids is that their roots should be moist, not wet, and should not be allowed to dry out. Consequently, after watering thoroughly and allowing the water to drain, expect the orchid media (the material in which the orchid resides) to be wet, but to eventually dry out until it is simply damp. It is imperative that the roots not be too damp as orchid roots will rot if kept too wet. Phalaenopsis fans will often refer to this as saying phalaenopsis don’t like “wet feet.” Be sure that the pot in which your orchid is kept will drain freely. If you take a close look at most “orchid pots” you’ll find that they are all designed to drain freely. Planters and pots that don’t allow water to drain away will kill your orchid.

Once all of your blossums have dropped, we’d recommend repotting the orchid, especially if the orchid is potted in spaghnum moss. Moreover, sphagnum moss will only last about 2 years at most, so you need to plan on repotting your orchid some time in the future. The good news is that the Jacksonville Orchid Society conducts Re-Potting Clinics at the Mandarin Ace Hardware store (see http://www.jaxorchidsociety.org/repotting.htm). You are invited to visit and we’ll try to answer any of your questions. Our website is a source of information at: http://www.jaxorchidsociety.org. You can also find good information on orchids in general at the American Orchid Society – http://www.aos.org. You may also find their information on the Phalaenopsis orchid of interest as well at: http://www.aos.org/orchids/culture-sheets/novice-phalaenopsis.aspx or http://www.aos.org/orchids/culture-sheets/phalaenopsis.aspx.

It’s actually funny… I’ve been hearing the “ice cube” watering instructions for years, but have never seen them until now!

 

Orchidwiz Express – No Longer Available?!

My copy of OrchidWiz Express is several years old. In a quest to see what might be required to update my copy, I went to the OrchidWiz site and found the announcement that OrchidWiz Express will no longer be available. However, until the end of August, they are offering a reduced rate upgrade for “Express” users to move up to the latest version of OrchidWiz Encyclopedia.

I do use my copy of OrchidWiz Express frequently, so I guess its time to make the investment in the upgrade. Nevertheless, I’m still hoping for a Mac and / or iPad version.

A Few Notes on Insecticide Use

ART_2575Recently, I was reviewing my notes of Jim Roberts (See Note 1) 2012 presentation to the Jacksonville Orchid Society on “Growing Orchids Outside.”  During that presentation, Jim made a little noted comment about application of insecticide.

He said: “Read the Instructions.”

This is really a very important observation.  Reading instructions as we all have seen, tell us about the amount of insecticide to use in a given application.  However, most of us stop at that point.  We shouldn’t; we really need to read all of the instructions and the warnings as well.

Many will say they get it, but then go right ahead and apply insecticides with little concern about their exposure after the first time they get some on themselves and nothing happens.  The truth, however, is a bit more complicated.

But first a little background.  Many of you know that I retired after a career in the Army.  I spent most of my time as a Chemical Officer; that is to say, an expert in the use of chemical, as well as biological and nuclear weapons.  Moreover, my last job before joining the Army was as an exterminator applying chemical insecticides.  No doubt, many will say: ok, I get the connection, but most don’t.  The important thing to know is that the “nerve agent” (See Note 2) series of chemical weapons are simply insecticides for bigger bugs – People!

Many of the more effective insecticides belong to a class of chemicals known as organophosphate compounds and were first  discovered shortly before World War II by German chemists looking for better insecticides.  The good news for us as insecticide users is that the ones we use are far weaker than those used as nerve agents.  But here’s the problem, they are still dangerous.  Many of these compounds act as a cumulative poison.  A little bit today won’t hurt, but who knows about tomorrow?  Moreover, the medical research is still not complete about sub-critical dosages and their effects on human health.

Ever notice a statement on some insecticides that “atropine is antidotal?”  Atropine is the first of several antidotes administered to counter-act the effects of nerve agent poisoning!

So what to do?  I’m not a “licensed professional,” but like everyone else, do use insecticides.  Here’s my method, use it if you will, without warranty.  My approach is intended to minimize my exposure:

  • Wear a charcoal-based respirator (charcoal-filled)
  • Wear clothing that leaves little to no exposed skin
  • Wear a hat
  • Wear wrap-around eye protection.
  • Wear chemical proof gloves
  • Apply insecticide with the wind behind you so that it blows any excess away from you
  • Don’t apply around gardens or other food stuffs
  • Don’t allow the overspray to hit gardens, foodstuffs, others, children, or pets.
  • Immediately upon finishing, wash your hands and exposed skin with cold water (which lessens likelihood of absorption)
  • Immediately upon finishing, separately wash your clothes and exposed articles.
  • Use only one sprayer for insecticides, don’t use it for anything else (You don’t want to spray high-strength insecticides on your garden by mistake!).
  • Rinse-out your sprayer after use to minimize exposure later.

This seems like a lot to go through just to use insecticide.  There is.  Having been in the business of killing little bugs and knowing how to defend against those trying to kill us bigger bugs, I choose to err on the side of caution.

On Orchid References

I posted the following to the Florida Orchid Growing group on Facebook in response to a question about references.  It tells a bit about me and my approach…

First a confession; I’m a recovering academic. As a result, one of the first things I look towards when exploring a new field is its supporting literature. Although I was exposed to orchids at a young age, it wasn’t until I moved to Florida 10 years ago that I’ve been able to pursue my love or orchids more actively. Below is the beginngs of a library. I’ll consider myself somewhat well-read when I’ve hit about 100 volumes, so I’ve got a ways to go (Please don’t tell my wife!).

Dad’s Orchid Notes

In going through my late father’s papers I came across the notes that follow.  They are a bit dated, but the general advice is still accurate.  It needs to be said that I am the Orchid Man’s Son; he started me with orchids when I was two years old.  He loved orchids all of his life and shared that love with me.  Enough said; Dad’s notes follow…

 SOME INFORMATION ABOUT THE ORCHID

The orchid is a plant that is no different from others, in that it requires water, light, warmth, and ventilation, though in somewhat different proportions than the average plant. Orchids are very hardy plants, and will take a great deal of mistreatment.

Some basic rules which will be of value in the culture of orchid plants follow:

Watering:
A. Plants should be thoroughly drenched with a hose or placed in a bucket of water until bubbles no longer appear from the plant; this is done especially at times when the plant has become thoroughly dried out. Do not water on a dull or shadyday— pick a day when the sun is shining and they will have a chance to dry out very quickly.

B. Over watering will rot the roots of the orchid, since the osmunda fiber, in which they are potted, will retain some moisture from six to 10 days, under normally dry conditions. If no rain has occurred for a week and the plants are out of doors, it is safe to water the plants, provided the osmunda fiber feels dry to the touch, they should be watered about once a week in the house.

C. It is much better to keep plants too dry than to let than stay damp for an extended period; letting plants dry out too long will merely retard their growth and slow down their flowering period — keeping them too wet will kill them.

D. If plants are to be kept in the house, the leaves should be sprayed with a hand sprayer atomizer about two or three times a day during the summer on normal days; once on a dull day. In winter, spray the plants about twice a day on bright days and once, or not at all, depending upon the feel of the potting fiber, on dull days. In the house, it is wise to set the plants a few inches above a pan of water, which will raise the humidity of the air around the plant.

Sunshine:
A. Winter time sun is not so strong as that in summer, thus plants may be subjected to almost unrestricted sun all day in a window, preferably on the south side of the house. A kitchen or bathroom window is desirable, since these are the most humid spots in the average home.

B. Sumner sun is quite strong and if unrestricted, may be injurious to foliage and blooms, in summer, plants do well when placed out- side under the sparse foliage of a small tree. Care should be taken to prevent squirrels from getting to the plants, since they may eat the tender shoots and buds — they are particularly fond of the blooms, as are some birds. A suggested plan is to hang plants on a clothesline under light shade of a tree where a great deal of light is available without the rays of the midday sun falling directly upon the plants. Morning and late afternoon sun are not too severe for the plants.

Ventilation:
A. During the summer, adequate ventilation is assured in the yard, on a porch, under a tree, or in a slat house, thus no problem exists outside the house.

B. If plants are to be kept in the house, a window should be cracked very slightly in order to keep air from becoming stagnant. Do not open opposite windows to form a draft, since plants will suffer due to too much cooling; it may also create a problem in your personal comfort and in heat loss to the house. Pick a window where it is a little cooler than the rest of the house and normal flow of air currents will probably make it unnecessary to open a window at all.

Warmth:
Temperatures of 50 to 80 degrees Fahrenheit are good for the plants; they can stand temperatures down to, but not including freezing, and up to 100 degrees. It is safe to say that if you keep yourself comfortable and subject the orchids to the same temperature, you will provide a good growing environment.

Flowering:
Blooming period for a mature plant is fairly constant, thus you may expect it to bloom about the same time each year, provided it gets the same care from year to year. Plants should be watered thoroughly just as the blooms begin to break open, then no more root water should be given until the blooms fall off. Daily foliage spray may be applied while in bloom; however, avoid getting water on the bloom to prevent fading and water-spotting of the bloom. After blooms fall off or are out, normal watering and treatment may be resumed.

Potting:
Potting is done in osmunda fiber and should be good for about two to three years. Plants are potted with the old growth near the edge of the pot and the new growth will progress toward the other edge. Repotting should be accomplished when the new growth touches the opposite edge. Someone familiar with the technique should be called upon to repot the plants and demonstrate the technique to you the first time. It may be advisable at time of repotting to split the plant into one or more additional plants, adding to your collection; the person who repots you plant should be able to advise you in this matter and make the division for you in the event it is advisable.

An excellent book on orchids is “Home Orchid Growing,” by Dorothy Northern, and is found, along with many other good books on the subject, at most public libraries.
