  • 4. Editor’s Note: M ore change awaits you. We are now offering a PDF version of Hobby Greenhouse magazine, which can be downloaded onto your computer or hand-held device. This PDF version will be sent at no charge to all current Hobby Greenhouse Association members for whom we have an email address. You dont have to do anything. Just wait for it to arrive. If you dont want it, simply opt out. When your current membership is ready for renewal, you’ll have the option of continuing to get both the paper and PDF versions of the magazine or receiving only the PDF version at a reduced rate of $14 a year. New members will have this same choice. In this way, we hope to increase our appeal to younger generations of greenhouse gardeners for whom e-books and e-zines are a routine part of daily life. Another change you’ll notice is a new section on garden tools in this issue. Both good and badgarden tools are being sold today, and it is always useful to get some help distinguishing between thetwo. We plan on trying out a variety of greenhouse tools and telling you what we learn. This monthwe feature tools by the English company Burgon & Ball, which has kindly given us the stainlesssteel tool set shown on page 13. We’ll send this premium tool set to the person who brings to ourassociation the most new members over the next two months, so I encourage you to sign up everygreenhouse gardener you can find and help our association grow. Finally, I call your attention to the mini-survey in this issue. It is hard to operate in a vacuum, sowe’d like to find out exactly what you’d like to see in this magazine. With your help, we can featurearticles and information specifically tailored to your interests. So please fill out the survey and sendit in.

  • 7. Your Questions AnsweredNote: All responses may be edited for length and clarity. Black and Green AphidsI have been fighting green and black aphids constantly for years. I, like so many others, bring in plants into thegreenhouse in late fall. Usually in too big of a hurry. Mums are terrible for aphids, both kinds. I change my spraysand usually get them under control. What other people doing to combat them?Bob Carney FLI purchase ladybugs (lady beetles) once or twice in the spring (or as they become available), make sure I keepthe doors and vents closed for a week to 10 days, and that usually gets them under control. Other times of year Iuse insecticidal soap spray as needed but not when ladybugs are in action. Spraying with insecticidal soap (reallydrenching plants) before you bring them into the GH in the fall also helps. You can really drench them, then spraybriskly again (1/2 hour or so) with regular water to wash off the soapy scum. I do not use any other pesticides.Alice Dionne, WAAn old gardener once told me that the best way to get rid of aphids is to regularly spray your plants with a solutionof water into which garlic has been left for a while. The garlic water gets rid of aphids and then you can move theplants into your greenhouse without problems. If you do suspect aphids on your plants, make an isolation chamberin the greenhouse with either a large glass fish tank and a close fitting pane of glass as a cover or get one of theinexpensive small plastic greenhouses and use it as an isolation chamber. Put your plants into it and leave themthere until you are sure your plants have no aphids then move them into your greenhouse. You can even movethe isolation chamber into the greenhouse as long as you open it outside until you are sure that your plants haveno aphids. Id also leave a can of garlic water in the isolation chamber, if it doesnt kill off the aphids itll give thembad breath!Roger Marshall, RIIt is important to NOT rush bringing your plants inside, but inspect for pests. Even an alcohol spray will help greatlyin reducing the infestation brought indoors. Once indoors, the environment is ripe for spreading. Follow up every7 days until there are no signs of infestation. Doing so on sunny days when the temperature is high will be moreeffective because the little buggers are more active and not prone to hide, or be slow. It is not about what you use,but being diligent about it.Greg New FL (continued on next page)Hobby Greenhouse Page 7
  • 8. Your Questions Answered... againIn the summer I remove all of the plants from my greenhouse in the spring (March or April,depending on the weather).In fall, around September, I go through a greenhouse cleaning process. I don’t know how scientific it is but the onlyyear I had a problem with insects was the year I neglected to do it. My greenhouse is 12 x 24 with a door at eachend. I remove the benches that can be taken out (some are built in) and first blow out all of the sand and debris.Then I wash it all down with a hose. Then I wash it all down with bleach in a hose end sprayer (mixes the bleachand water). I let it dry, then sweep and blow some more. I have a lot of tropical plants and all sorts of insects lovethem. I don’t like to use pesticides but if necessary, while the plant is still outside I might spray with insecticidalsoap. But once they’re in the greenhouse, if I see a bug I isolate that plant and spray with plain rubbing alcohol. Ido on occasion get fungus gnats and, although annoying, they don’t hurt anything. I always have lizards and toadsthat sneak in and overwinter, and I don’t want to poison them, or myself with anything stronger. I really think themost important thing is to start every fall with a really clean greenhouse. And, if a plant is really infested, toss it.Carol Mirabella Finch GA NEW CHAPTER BEING FORMED PHILLY HOBBY GREENHOUSE Meetings will be held at : The Horticulture Center, West Fairmount Park, Philadelphia, PA The purpose of this organization shall be to stimulate and promote interest in growing plants under different conditions.

Roger Marshall Frost Protek Plant CoverS You may have used a row cover to protect your plants or wrapped them in a blanket when a frost is forecast, leaving your garden looking like something out of Sanford and Son. Now you can protect your plants against a moderate frost with an easy to use, slip on cover. The Frost Protek has a drawstring at the bottom to enable you to pull it snugly around your plants. The cover is permeable but it will also keep insect pests off your plants while aloowing rain or moisture to penetrate. It also helps to protect plants against wind and sun and may keep larger pests (deer and rabbits) off them as well, When not in use the Frost Protek covers can be folded and netly stowed in your potting shed. The covers are sold in garden centers across the country and come in various sizes. Why not buy one or two now and The Hobby Greenhouse Association does not have them ready for use endorse or promote products.

I’ll group theforms together, calling them all just greenhouses. Beforediscussing options, let’s look at some basic considerations. within to above freezing all year. In summer you will provide ventilation and shade to control overheating. Almost all plants will need air temperatures above freezing and below 120F to survive. As growth only occurs between about 50F and 90F, heating the whole greenhouse to any temperature The purpose of having a hobby greenhouse is to take between 32F and about 50F is a waste of money.

Your time and dedication are factors too, as temperatures in the growing range are common in winter,no plant can be left alone for extended periods without so a heater won’t even come on during many days andany care. Plants which survive outside in your climate even infrequently at night due to stored heat. Plants can,will need water, at a minimum, in your greenhouse and without harm, grow when temperatures are suitable, goprobably need some protection from temperature swings dormant when too cool and resume growth the next day.and likely some protection from insects too.

The later in the year that you takecuttings, the more difficult it usually is to get thecuttings to grow. There are three methods of taking cuttings.You can take cuttings from the stem tips, youcan slice off a side shoot (called a basal cutting),or you can take a heel cutting by pulling a smallbranch off the main stem. Different plants preferdifferent cutting methods. To take tip cuttings, simply cut off the tips ofstems, taking two or three leaves, dip the cut endin rooting hormone, and plant it in well-drainedsoil.

Proofing Seeds You can keep seeds from year to year in a cool place, but gradually they may lose their viability. Proof old seeds by starting ten or twenty in damp paper towels. Put the seeds between two damp towels and put them in a plastic zip top bag. Set the bag in a warm place to germinate where temperatures are about 70 degrees. After four or five days remove the seeds from the bag and count the number of seeds that have germinated. If half your seeds have germinated, you have a 50% germination rate. When you plant the remainder of your seeds, double your normal seeding rate to account for the lack of germination.

Greenhouse factoids Greenhouses were originally called glasshouses and had small panes of glass overlapped at the bottom to prevent heat loss. The overlap was hard to clean and often harbored moss and other plant life. In the drab winter months of 19th century England glasshouses provided a bright green splash of color in the winter landscape. Because of the greeness the structures became known as greenhouses. A big fad inVictorian England was to grow pineapples, when the structure was know as the pineapplery. If oranges were grown, then it was often known as the orangery. Similarly, if grapes were grown it might be known as the vinery. To keep the large plant pots warm in winter, fresh horse manure and straw was piled around each plant container. As the manure rotted down it gave off heat which kept the temperature up. Larger greenhouses used wood fired steam heating systems with pipes around the base below the greenhouse glass and while it may seem impossible, many greenhouses including England’s most famous Crystal Palace, burned down when the heating system went awry.Hobby Greenhouse Page 21

Watering ficuses can be tricky, especially if the plants are large. Allow the soil in large pots to dry out to a depth of 2-3 inches in between waterings. Plants in lower light will need much less water. If you forget and let them get too dry, ficuses will may suddenly drop all their leaves, but unless they are totally parched you can bring them around with regular watering. No fertilizer at this point, please! Check to see if the branches are still supple. If so, the plant can be saved. Leaf drop may also occur as a result of sudden changes of temperature and overwatering. The common insect pests found on houseplants also attack ficuses. Infestations of scale insects, mealy bugs, and spider mites are not atypical. It’s always a challenge dealing with these pests, especially when the plants are large. Horticultural oils mixed with water are especially effective for dealing with scale insects, but will also work on the other two pests. It’s best to do this outside during warm weather, but never in direct sun to avoid damage to the leaves. Indoors, the logistics of shielding your walls, furniture and floor coverings from damage can prove formidable. You’ll generally need to apply the oil- water mixture more than once. Ficuses are usually not damaged by this treatment, unless you get carried away and add too much of the oil. Remember, your goal is to suffocate the insects, not the plant!

Whether the latest version is less buggy, we shall have to see. Hobby Greenhouse Writing Guidelines 1. Aim for articles between 600 and 1200 words long. As we move toward web-based publication, shorter, well-illustrated stories will work best. If you have an article much longer than this guideline, think about breaking it into parts for inclusion in more than one issue. 2. We like to see as many high-resolution photographs as possible accompanying a story. Even if we can’t use all of your submitted photos, it is helpful to have a variety to choose from. At a minimum, try to include at least six good images. Remember the old adage “A picture is worth a thousand words.” Good illustrations enhance an article greatly. 3. Do not embed images in the text. The only time that you might do this is if you have 10 to 20 images and want to show us where they should be placed. If you embed images in the text, we have to delete them to do the layout, so please supply your images separately. 4. If you email images to us, you may have to send them in multiple emails. We have found that three or four hi-resolution images per email is best. 5. Don’t be afraid to give your story a strong voice. Tell the readers what worked for you, why you think it worked, and anything you did that may have created problems. Personalizing a story in this way can often make it more interesting to read. 6. Especially if your article is on the long side, consider inserting some headings to make its structure and subtopics clearer. A few well-chosen headings can be very helpful to readers. Also, use one space between sentences, not two spaces. 7. Try not to digress from the main subject of your article. If you have something peripheral you’d like to say, consider putting it in a short sidebar. If the sidebar is getting long, you’re probably better off saving the peripheral topic for another article. 8. Please send your story to editorhobbygreenhouse@gmail.com. If you send in a printed version by snail mail, please also enclose an electronic version, either on CD or flash drive. CDs and flash drives are really good for lots of pictures. The snail mail address is: Editor, Hobby Greenhouse, 44 Fort Wetherill Road, Jamestown, RI 02835. 9. Hard-copy-only versions will need to be sent out to be retyped and may not be in the issue that you would like them to be in. If you send hard copy photographs, they will need to be scanned, and the scanning quality is often very poor. Polaroid pictures scan particularly badly. 10. We suggest that you check back if you have not heard from us within a week after submitting an article via email. Sometimes our server thinks perfectly legitimate emails are spam and deletes them.Hobby Greenhouse Page 25

Gardeners who have tried the battery-powered applicator found it comfortable to use, providing a steady, even application rate. The new applicator cap has an inner fan powered by two AAA batteries, which come installed. The user simply flips open the top, points the cap toward the ground and switches on the fan. Gravity feeds the Preen granules into the fan, which distributes them easily and evenly. Adjusting the angle of the bottle changes the flow rate of the application. The bottles are refillable from Preen’s larger sized pails and bags. The batteries are estimated to run for a minimum of eight hours, which is enough to apply the equivalent of 80 bottles of Preen. The batteries are replaceable. Preen Garden Weed Preventer with the regular shake-top applicator cap is offered in bottles with 5.625 lbs. of product, estimated to cover 900 square feet, with a Suggested Retail Price of $17.99. The new Preen Garden Weed Preventer with the Power Spreader applicator cap is offered in a bonus size with 6.25 lbs. of product, estimated to cover 1,000 square feet, with a Suggested Retail Price of $22.99.Hobby Greenhouse Page 33
