Motes Notes - Florida Orchid Growing
Progress of the Season
Overall July has been wetter than usual but atypically much of the excess fell in one exceptional wet week. If our orchids escaped this onslaught, they fared well for most of the month with sufficient rain but also sufficient drying between rains.
Indeed, as the last of July has proved drier than usual, the threat of mites has loomed larger than usual. Mites are typically washed away by the heavy rains of summer but because of their ability to reproduce with incredible rapidity at high temperatures can become well established when several days pass without a heavy rain in the heat of summer. Use the methods outlined in Florida Orchid Growing to control mites.
Even if one has been virtuous and applied the proper snail bait in June, a new generation of snails is emerging. They are smaller and less noticeable, but still can do considerable damage. Control these new comers with several more applications of snail bait, lightly a week or 10 days apart.
We can capitalize on the slightly drier than normal conditions which are ending July by judicious watering and by occasionally allowing our plants to dry "Hard". An occasional weed in a potted orchid can be a good indicator. When most plants wilt, most orchids are happily safe from their mortal enemy, fungus. Let them dry!
With the early mangoes finished, now is a good time to prune them and indeed all our trees. Pruning vertical branches and the interior of trees allows beneficial light to reach our orchids. Such pruning also makes the tree more hurricane resistant. Trees which were pruned to provide optimal light for orchids naturalized on them were the ones which remained standing after Andrew.
The shorter days and longer nights of August mean early morning temperatures are often in the mid-70's. Rise early and enjoy the world cooled down.
January in Your Orchid Collection
January is somewhat like December but in reverse, with each succeeding day bringing longer hours of sunlight until days are long enough that afternoons return at the end of the month with extra sunshine to warm us after the extra sharp cold snaps. January, like December, is cold and dry, in fact even colder and drier. Dry is good, cold can be very bad. We need to accentuate the positive by especially... read entire article
February in Your Orchid Collection
Despite the bloom on the avocados and the burgeoning new leaves on the live oaks, February is not spring in South Florida. Danger of freeze continues past mid month and frost can occur still into March. Even if the weather is balmy, it's too early to let down our guard or take down any protection we have mounted against the cold. The trend however is toward the positive as each lengthening day brings extra hours of warming sunshine... read entire article
March in Your Orchid Collection
Signs of spring abound with an abundance of emerging flower spikes and buds. The flush of spring growth will follow soon so plan your repotting program which should begin in earnest this month. The best time to repot is right before the new roots start growing so the plants will reestablish quickly. Watch for signs of mites, particularly on thin leaved orchids like the catasetinae and grammatophyllums, and treat any problems promptly...continue reading
April in Your Orchid Collection
Far from the cruelest, April is the kindest month to South Florida orchid growers. The weather in April is definitely settled into warm, even deliciously hot, with passing cold fronts only adding the delight of a pleasant change in temperature. The clean, bright days brimming with abundant sunlight and the low relative humidity create the high drying potential that orchids love. ... read entire article
May in Your Orchid Collection
May is a month of transition in South Florida. Early in the month we can expect the driest weather of the year. Because of the clarity of the air and lack of cloud cover, temperatures rise rapidly in the late morning and can reach the upper eighties or nineties by mid afternoon before cooling substantially in late afternoon. Fortunately, over night radiant cooling rapidly dissipates the previous day's... read entire article
June in Your Orchid Collection
June is the most dramatically tropical month in South Florida. As the southeast Trade Winds blow cool moist air off the Gulf Stream daily, as surely the heating effect of the center of the peninsula percolates up massive thunder heads. The increased cloud cover drawing a veil across the afternoon sun provides much cooling relief for our plants... read entire article
July in Your Orchid Collection
Although it mostly passes unnoticed to millions locked in their air-conditioned bubbles, July in South Florida is quite different from June. While the pattern of afternoon showers built from the moisture of the morning's sea breeze persists in July, the thunder-storms are sharper and shorter. The clouds linger less and the foliage dries more quickly. Less quantity of rain falls in July than in June... read entire article
August in Your Orchid Collection
July and August are the two most similar months in South Florida. Most of the advice on watering, disease and pest control in last month's calendar still apply but subtle changes are taking place. Although it may not seem so, as temperatures climb into the low nineties most afternoons, summer is in retreat: each day a little shorter, each night a little longer. With shorter days the importance of watering as early... read entire article
September in Your Orchid Collection
September looms as the only truly dismal month in South Florida. Even without the prospect of the unspeakable 'H' word, September disheartens since it is easily the dampest, dullest month in the year. Although more inches of rain fall in June, more hours of rain occur in the often slow, seemingly endless drizzles of September. Frequently a day or two can pass without so much as a solid hour of truly bright... read entire article
October in Your Orchid Collection
October is a month of change in South Florida. If the Romans had lived here where we do, they would have named this month for their two faced god Janus. Usually around the middle of the month, and certainly by the end of the month, the first strong cold front pushes into South Florida bringing to a close the monolithic heat and damp of summer and ushering in weather as most of the continent knows it... read entire article
November in Your Orchid Collection
In November we can no longer afford to be dominated by the illusion, so easy here at the northern edge of the tropics, that summer will never end. Although Indian Summer persists for the whole winter in South Florida, November is the month to prepare our plants for those short sharp blasts of cold which are inevitably coming as each successive cold front pushes the overall temperature a little lower... read entire article
December in Your Orchid Collection
December marks the beginning of the serious dry season in South Florida. While this additional dryness provides relief from the autumnal rains that can bring so many fungal problems, December is also the month of shortest day lengths. This contracted period of light, on the contrary, reduces severely the drying potential for our plants. Nature thus both gives and takes away from us in December. We must... read entire article
