Motes Notes - Florida Orchid Growing
Progress of the Season
September has come to an exceptionally dry and pleasant end. For the first time in a lifetime one could wish for a little more rain in September. This unusual mini-drought has been extremely beneficial for our orchids. The disease pressures that have built across the summer, have not reached the crescendo they usually achieve in the drizzle of September. The lack of rain has also brought more sunshine and greater heat, drying our plants more quickly, which is always a good thing.
Careful watering, only when truly necessary, will preserve the benefits that have accrued from this unusually dry weather. Should we be lucky enough for this pattern to persist, a watchful eye will need to be kept for the mites and Thrips which are normally washed clear of our plants at this time of year. They, like our orchids, love to stay dry.
Now is the time to space out all the plants which are preparing to go dormant: catasetums, dendrobiums of section Callista and the Nobile types, calanthes etc. The extra space will allow them to dry more quickly and stay dry longer. Cattleyas that have finished their growth will appreciate the extra space as well. Fertilizer should be withheld from all these.
Continue to water and fertilize the vandas and Phals. Be ready to protect these should we get early cold.
The longer nights of October yield up cooler mornings. Early risers get to enjoy a wonderful time in South Florida. Don't miss out, be outside!
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
