Volume 31, No. 10, June, 2009 ASPIRIN AND GROWING ORCHIDS Newsletter excerpts No. 201 –F - G by Dot Henley
Besides the fun, the good thing about teaching biology for years was learning more. When I taught, I started the school year with a lab where students diluted aspirin (325 mg
adult dose) in water and then poured the solution on radishes, oats or other quick-growing vegetables. The lab never failed, The strong (1 part aspirin to 1,000 parts water) stunted the seedlings; the medium ( 1/10,000 dilution) groups grew remarkably better than the water control group; and the weak (1/100,000 dilution) grew no better than the water control group.
Students learned that aspirin contains salicin (C13H1S07), which is found in the bark of
willow trees. Native Americans chewed on willow twist to relieve headaches, and later botanists found that duckweed and other aquatic plants that grew in willow-edged streams grew better and matured faster due to the slaicin. Turn salicin into salicylic acid and voila! Aspirin is made. Recent literature indicates that aspirin is also and effective agent in treating some human fungal infections.
About a year ago, armed with all this information. I began treating our orchid collection
to a weekly dose of aspirin. I found that I could approximately duplicate the good 1/10,000 dilution by adding three quarters of one aspirin (325 milligrams) to a gallon (4 liters) of water. We have about 2,000 orchids and I used15 aspirins in a 20-gallon hose-end sprayer. In the growing season, I added 6 tablespoons of fertilizer and a squirt of Whisk or Dawn. In winter, I used 3 tablespoons of fertilizer. (Forgive the teacher repetition, but one whole aspirin per gallon of water will stunt growth and you may not want to use this system if you have acid water. Our water has a normal pH of 9.0 and the aspirin lower the pH to 8.6. Of course, the orchids receive rainwater or tap water as needed during the week.
To make 12 gallons of fertilizer solution, combine 9 aspirin with 12 gallons of water; for
4 gallons, add three aspirin to 4 gallons of water; and for only one gallon dilute one aspirin in a cup of water, discard 1/4 cup of this, and then add enough water to make one gallon.
Our plants have more blooms, bigger growths and fewer fungal problems since aspirin
became part of our culture. The only changes in culture have been the addition of aspirin once a week. Maybe it is the lower pH, or perhaps the magic that things our blood and stops our aches and pains can also help us grow better orchids.
The other thing I learned that I have used for several years came from a science project
done by one of my students. It was not applied to orchids, but to six or so varieties of garden plants where the student tried to show that the highest metabolic rate occurred at 11 am by the sun and that fertilizer and weed killer were best applied at that time. Even half-strength worked as well as full-strength. Fewer chemicals can't be all bad. ed. note:- I have read in very old gardening books that if you want to make a cutting of a difficult shrub you put it in water with some lengths of willow twig as it will make roots grow faster on the chosen cutting. It is interesting to find out that aspirin originated with willow twigs.

Volume 31, No. 10, June, 2009 Keeping Windowsill Cattleyas Healthy Ned Mattinen Although I greatly admire the Cypripedium, Phalaenopsis, Cymbidium, Odontos and many other orchids. . . the Cattleya will always rank top on my list as I find it the easiest orchid to grow, the hardiest, longest-lived and one of the most fascinating that I have had in my windowsill collection. How many other orchids can be obtained in as many different colors as the Cattleya (hybrids, especially), and the many fragrant Cattleyas also! They are definitely of very easy culture for home windowsills, but I will mention, for the amateur grower especially, how to avoid a few pitfalls while growing these exotic orchids in the home. Seedlings. . . Mature Plants and Sunlight Fresh air and sunshine are needed for Cattleya plants, but young plants in 3" and smaller pots should never be in full sunlight, as they will weaken badly (especially in the summer months). Keep small pot seedlings between larger pots where the sun isn't quite so intense (young plants should never be in the very front of the window). When the plants have reached 4-inch pot size, move them gradually into more sunlight. There are times when a young plant or mature plant will show shriveling foliage. If all the foliage is shriveled on the plant, correct the cause and move the plant a bit farther away from strong sunlight. (Over- watering. . . stagnant potting media. . . too much sunlight (if the entire group of leaves are yellow and shriveling) are some of the causes. Potting Media Stagnant or decomposing potting media is very detrimental to Cattleya orchids. . . affecting flower quality, size and production of blooms, besides weakening the plant. Very little root growth is noted during decomposing or stagnant conditions in the potting media. Some redwood bark in the pots may appear very dry and hard in appearance, with an "off" coloring to the bark chips as though a dirty grayish-brown color. When the bark has this appearance, do not depend on a stagnant odor to be prominent, as it will not always be prevalent when the topmost bark (surface) is drier than the bark underneath. Dig down into the bark a few inches deep and you may then note a stagnant odor and find a few bark chips covered with stringy white patches of fungi. It is time to repot . . . and fast (that is, if there are no buds or flowers on the plant. . . if so, wait until after they have flowered before repotting)! If you are a user of redwood bark for potting media, I would highly recommend Dimmick's redwood bark as one of the best that I have ever used. No other redwood bark has surpassed this brand with me. I have noted after using this product over a year that every Cattleya orchid potted with Dimmick's redwood bark produced new growth quicker than any other bark I've used, and the plants established themselves without any setback. No millipede problems with this bark to this day. Looks as though I will leave my favorite sphagnum far behind! I use the medium size bark for pots from 4-inch to l0-inch size. At only $6.95 a bushel size bag, shipping charges paid, you can't go wrong! Volume 31, No. 10, June, 2009 Rest Period for Cattleyas After your Cattleyas have finished blooming, give them a rest period for about a month with a little less sunlight, and stretch the watering period to a couple of days longer. (If you have been watering the plants every seven days, do it every nine days instead. . . for a 30-31 day period.) After my plants have finished blooming, I move them back a bit from the window and put other plants (which are due for buds or bloom) in their place. Keep rotating plants all year around. The approximate size of scale is shown. Also illustrated is the coming "coup de grace’ from both pests Root System of Cattleyas Most healthy Cattleyas have at least several roots creeping out of their pots. Dead roots appear tannish or brown and are very dry to the touch, whereas live roots are white with green tips and quite brittle. The live aerial roots serve as an excellent watering gauge and will let you know just how much water you have given the plants. I have found that Forman & Krumpe's method of "reading the roots" is quite accurate, with perfection being when the green of the root tips measure about 1/4 inch. . . and, over one inch indicating that the plants need more watering. 1/16 of an inch of green tip or less indicates a bit too much watering. Volume 31, No. 10, June, 2009 Less Fertilizing ForWindowsill Cattleyas For home windowsill growers of Cattleya, I believe that fertilizing of Cattleyas more than once a month in winter months can hold back blooming of the plants. Fertilizing more than twice a month during spring and summer months may also hold back blooms and only produce a lot of new growth. Cattleya and other epiphytic orchids grow on trees and cliffs in their natural environment and do not receive as much nutrients as the terrestrial orchids. . . so why kill them by over feeding! I very seldom fertilize my Cattleyas, and only in the late spring and summer once a month on 1/2 strength solutions of fertilizer, if I do (after watering the plants). I find the best time to do this is when foliage is more on the chartreuse side than green, in mid-summer to retard chlorosis. I will say that very young plants from 1" to 3" pots can use fertilizing more than mature plants, as they need it in order to mature. (Greenhouse grown Cattleyas of all sizes are fertilized more often than home windowsill grown plants, as the latter plants are grown under more light and other conditions, which will allow for more fertilizing.) Scale and Mealy Bug I recall about six years ago visiting a woman who grew orchids and other p1ants together in a large sun porch. (The invitation to her home was mainly for me to diagnose her ailing and shriveling Cattleya orchids.) One cannot imagine what a jolt I received to observe 35 orchid plants covered with mealy bug! Every Cattleya was loaded with mealy bugs. . . and a sorry sight it was! A number of the plants were too far gone to be remedied or saved. The cottony patches of bugs seemed especially fond of the basal area of the pseudobulb, but also were noted near me leaf-bulb conjunction area. If these pests should be found on any of your Cattleyas get rid of them as quickly as possible. . .by handpicking with tweezers. (Destroy picked up mealy bug by flame.) Spray the plants with a good pesticide after picking most off the plants. Another very injurious pest to Cattleya orchids is scale, like mealy bug, scale can shrivel both foliage and pseudobulbs in no time at all. About 12 years ago, one of my Cattleyas had a bad case of scale from an unknown source, which I handpicked off the plant and sprayed the plant afterwards with Acme indoor plant spray. That was the first and last case (l hope) of scale. A tiny tannish "scab" is what scale exactly resembles. New orchid growers should watch for both of these pests and get rid of them pronto! Poinsettia, gardenia, African violets and several other plants have been known carriers of injurious pests. Perhaps that is why I haven't had these pests on my Cattleyas only once. . . twelve years ago, when I threw out all other house plants! Misting Your Cattleyas If you do not have a humidifying system in your home, try misting your Cattleyas a couple times a day. They'll love it! Especially if the humidity content in the room is below 50%. Here in the north, humidity is quite low outdoors during cold months and very low Volume 31, No. 10, June, 2009
indoors, if one does not have a humidifier. I depend mostly on my humidity trays underneath the plants, but when I find the time I fill my one-quart size "science trigger spray gun" with water and empty about 3/4 of it out over the plants in mist form. (I do not spray over plants with open flowers or buds which are just opening. . . but I do include buds which have no open seams.) Plants which have just arrived from the nurseries, via mail especially, are almost immediately misted at least three times a day since they have been accustomed to higher humidity than what my apartment can furnish. Buds can shrivel on these plants quickly if the home humidity is much under 50% at that time. (Do not aim your spray gun directly at the plants, but more towards the ceiling so that a fine soft mist will slowly settle on the plants. You do not have to "drench" the plants, , , but just enough moisture like a thin, visible film over the foliage and buds.) Do not mist the budded plants if the sun is shining on them. Cattleyas Outdoors in Northern United States Recently, I have begun using my outdoor windowsill ledges for cooler night temperature growing to force buds more quickly. It works nicely! While indoor night temperatures remain between 72-76 degrees F. for the month of August (which has been Duluth's hottest season in years), I find our recent outdoor temperatures at night between 50-58 degrees F. and the plants now setting buds after being set on the outside window ledges. The plants are returned indoors for the daytime. Plants which had lost their "zip" from the heat of the day showed a marked improvement from the cool night treatment! If you plan on leaving your Cattleyas outdoors day and night in summer months, be sure to spray the plants with insecticide once a week without fail. I spray the entire area thoroughly before setting the plants in position. Do not set plants directly on the ground, but on boxes or ledges, which are several feet off the ground to avoid damage by insects and animals. Cattleya orchids outdoors will dry out quicker than indoors and may have to be watered twice a week or more depending on the pot size. In the northern states, Cattleyas may have to be brought back into the home before the latter part of September to avoid freezing. Sunburn to Cattleyas can be very severe if there is no overhead protection or shading of the plants. (Do not select a windy spot for your plants or the blooms may not be on for long!) Shaded Bud Problem There are times when the home windowsill grower of Cattleyas will note that due to the position of his plant(s), which cannot be turned to face the sunlight (when in bud), he will have to resort to other methods in order to have the sunlight reach the new starting buds in the leaf-bulb conjunction. When plants are too large or foliage extends in the way of other plants, some budded plants cannot be turned to have the sunlight enter the leaf-bulb conjunction. I then use my aluminum foil technique or method to introduce more light into the leaf-bulb conjunction as illustrated. Volume 31, No. 10, June, 2009
I use about a 3-inch square of aluminum foil. , , keeping the bright side of the foil facing the bud and the upper part of the foil about 2 ½ inches from the conjunction. This method is especially helpful to northern windowsill growers whose orchids do not receive quite the amount of sunlight as other portions of the United States do. I have no idea how the aluminum foil method would affect Cattleyas grown in states with a bit more sunlight, that is, if burning of the buds can occur or not, , . but if you are from such an area and wish to try this method it may be best to use a 4-inch strip of aluminum foil and keep the topmost part of it about 3-3 ½ inches from the conjunction to avoid too strong sunlight. (When buds are high enough on the plant for the sunlight to reach them I then remove the foil.) Crinkling the aluminum foil should help prevent burning somewhat and distribute the light more evenly. As yet, I haven't had any burning problems of the buds here.
