The fall months are depicted as a time when plants are preparing to take their long-awaited winter nap as leaves (deciduous plants) begin to fall from the trees along with the slow growth of garden plants. And while this is true for many plants there are so many that continue to grow (every green plant) throughout the year. Deciduous plants lose their leaves at a certain time of the year but will produce fresh beautiful leaves when the growing season or warmer months returns. Evergreen plants are plants that retain their leaves throughout the year and into the following growing season. However, in our discussion, we will be turning our attention to orchids.

Installing orchids in your indoor living space during the fall months is a great way to not only connect with nature indoors but to really brighten and liven up things  Over the years I have worked with many species of orchids on so many garden projects creating many beautiful shows that were just simply amazing. There is said to be about 47 orchid species that bring their very own uniqueness with their many leaf shape, flower designs, sizes, and colors.

While we cannot discuss all 47 of them which is beyond the scope of this article we will be taking a closer look at at least 5 of them so you can know how to care for them during the fall months. So with that said we begin our discussion on orchids to plant in the fall in South Florida.

1. Phalenopsis Orchids

Phalenopsis orchids

Phalenopsis orchids are native to the tropical regions of Australia and Asia, this perennial herbaceous plant thrives best in USDA Hardiness Zones 10 to 12. Phalaenopsis orchids require good lighting, however, direct lighting will scorch the leaves, if insufficient lighting is an issue then consider installing artificial or grow lights. A 40 0r 70 fluorescent tube can work, once the light or lights are installed place the orchid 12 inches underneath the light. Rotate phalaenopsis from time to time to keep the growth even. During the colder months place your phalaenopsis in a south-facing or east-facing window to get some direct sunlight. Insufficient lighting will result in dark green leaves while too much lighting will encourage a reddish or pink tinge to form along the leaf margins that will turn yellow in time.

During the growing season water your phalaenopsis weekly or whenever its exposed roots turn silvery white, water your phalaenopsis once a week. Pour room-temperature water slowly over the bark. Repeat this action 3 0r 4 times to ensure the orchid gets adequate water. Once the orchid pot is completely drained return the plant to its position, always water orchids from the roots because if the leaves get wet and that moisture is allowed to remain will encourage rot.

Root and stem rot occur when the growing medium has been overwatered and is saturated, during the growing season which is the summer months apply a diluted orchid fertilizer every third or fourth week. During the spring fall and winter months avoid fertilizer application which will encourage leaf growth and no bloom.

The temperature and the humidity level play an important part in the health of your orchid, the inside temperature can be anywhere from 65 to 85 degrees Fahrenheit. A fan or humidifier will help to keep the inside atmosphere comfortable. Mature orchids can be pruned once a year during the dormancy period after the blooms have faded. Snip back unhealthy roots, that are brown, mushy, or dead, and remove spent flowers with the help of a clean sharp knife or scissors. Cut the top portion of the stem back to 1- inch above a node to encourage a new stem section and more blooms.

2. Dendrobium Orchids

Dendrobium orchids are native to tropical and subtropical  Asia, Australia, and many Pacific islands, dendrobiums are epiphytes meaning they can grow on other plants. In nature, dendrobiums can be seen growing on other plants, the USDA Hardiness Zones for these orchids are 9 to 12, and there are said to be almost 2000 species of this plant type, water your dendrobium with tepid rainwater in the summer just enough to ensure that the potting mix dose, not dry out.

Once watering is done make sure that the remaining water is drained from the drip try to ensure that the roots are not exposed to standing water, during the growing season mist on a regular basis, and feed every third watering with orchid fertilizer.  A daytime temperature between 16-21°C (61-70°F) during summer time with a 5°C (10°F) difference will keep your dendrobium in good shape.

During the winter months locate your orchid in an area that’s warm, and bright with cool temperatures between 10-13°C (50-55°F), ensure during the winter months that your dendrobium is exposed to direct light. Once the flowers start to appear place orchids back in their original place once cold months have passed.

Dendrobiums prefer a humidity level between 50 and 70 percent, if the tips of these orchids turn brown may be a sign that the air is too dry a spinning fan or humidifier will offer some help.

Allow the potting medium to dry out between watering. Applying water once a week is sufficient, after a week if the potting medium is still damp wait about a day or two then add water or give the orchid a good soaking.
