At Christmas time, my husband did a good deed and received an orchid as a token of appreciation. Since we knew nothing about raising orchids except for their alleged finicky and difficult reputation we went into panic mode when the giver also said, “By the way it needs repotting!” So now what were we to do with this thing?
The first step was to decide what type of orchid this was in order to provide the best growing conditions. There are five major orchid types: Cattleya, Paphiopedilum, Phalaenopsis, Dendrobium, and Oncidium. Phalaenopsis (moth orchids) and some Paphiopedilum varieties (slipper orchids) are best suited for home environments. Flowers on these orchids are long lasting. Phalaenopsis flowers can last from two to six months. My orchid arrived without a tag, but had the leaf and flower structure of a Phalaenopsis orchid and arrived potted in sphagnum moss rather than regular potting mix, suggesting that it was epiphytic and not terrestrial.
Once you identify your orchid, you will be able to plan for its care. Orchids really seem very easy to grow if you supply the correct potting mix, light requirements, water, and fertilizer. The correct conditions usually allow you to successfully grow any plant.
Because many orchids are tropical in origin and are found in nature growing on trees or tree branches, they require a potting mix that is composed of bark, sphagnum moss or a fibrous potting mix. They get most of their water and nutrients from the air through aerial roots. The potting mix should let the water flow through freely and orchids should never be left in standing water. Water again when the potting mix has dried out some but not completely. The roots should not be trimmed. Because many orchids are native to the tropics, they may benefit from a more humid environment than we typically have in our Maine homes in the winter. Putting your orchid on a tray of gravel and water with the roots above the water level will provide some humidity.
Orchids need good light and warm temperatures — about 68-75 degrees during the day and about 10 degrees cooler at night — in order to set buds. Orchids may fail to bloom if night temperatures are the same or very close to daytime temperatures. A two-week period in spring or fall where temperatures at night are kept ten to fifteen degrees cooler than during the day should initiate flower development, assuming the plant is receiving adequate light levels.
Orchids are intolerant of temperatures that are either too low or too high, so you may need sheer curtains in the summer to reduce temperatures in south or west-facing windows. You may choose to grow orchids under fluorescent lights if you don’t have an east, south or west-facing window. The lights should be about 8-12 inches above the orchids’ foliage, and should be on from 12-14 hours a day.
Orchids need fertilizer for good growth and flowering, and are also very sensitive to over-fertilization that can cause root damage. Only fertilize actively growing plants and do not fertilize during the plant’s rest period. Use a special orchid fertilizer or a good houseplant fertilizer and feed plants potted in bark every two weeks and plants in sphagnum once a month following the label directions.

In August, we gardeners are typically awash in produce, so much so that putting it to good use becomes a challenge. Our friends, neighbors, and co-workers grimace as they see us coming with yet another bag full of zucchini, carrots, and beans. So, rather than doing the same thing this year, commit now to making a plan about where your high-quality excess produce is going to go.
Why It Matters
Both nationally and regionally, Maine’s food insecurity ranking is frightening; third highest in the nation, highest in New England.
Food insecurity in wealthy nations like the US doesn’t look like the stereotypical images of swollen bellies and stick-like arms and legs. Rather, in Maine and elsewhere, it is more likely to look like obesity; the result that in America, calorie-dense, nutrient poor food is generally less expensive than nutrient rich food. So, making a plan to donate your garden produce to those with limited access to fresh produce just might start to turn the tide against food insecurity here in Maine.
