Part I: What is an orchid?:

Part I: What is an orchid? Orchidaceae Flowering plants Monocotyledons Unique flower structure 56,000 kinds of orchids in 1965 About 1000 new orchids are added each year. Most are perennial herbs Epiphytes grow on trees or shrubs. Lithophytes grow on rocks. Terrestrial grow in the ground. Saprophytes get sustenance from decaying matter. Two are subterranean. Cattleya by R. Voelker

Part I: What is an orchid?:

Part I: What is an orchid? Orchids exist on every continent except Antarctica Temperate orchids are usually terrestrial. Tropical orchids are usually either epiphytic or lithophytic.   Roots types are varied Terrestrial orchids usually have tuberous or fibrous roots. Plants are symbiotic with fungi. As orchids left the ground, roots changed. Became anchors. Became water and food gatherers.   Orchids vary greatly in size   Largest can be over eight feet tall and weigh over two tons. Smallest is two millimeters across and one cell thick Discovered in 2009.

Part II: Which orchids are native to our area?:

Part II: Which orchids are native to our area? In 1950 about 170 species/varieties were known to live north of Mexico   Many more have been discovered or have been introduced. In northern Florida 52 species presently occur, mostly terrestrial. Mostly small, unobtrusive, ground-hugging. Dormant most of the year. Lady’s Tresses bloom in spring. Bog orchids bloom in summer. None should be considered “houseplants.”

Part II: Which orchids are native to our area?:

Part II: Which orchids are native to our area? Greenfly Orchid is the most common epiphytic orchid in Northwest Florida Grows in moist areas in conjunction with resurrection fern. Grows in adjacent states. Protected in the wild and must not be collected. Not showy and should not be considered as a houseplant. Epidendrum conopseum by R. Voelker

Part III: What to look for/avoid when buying an orchid.:

Part III: What to look for/avoid when buying an orchid. What to look for:   Buy plants that will thrive in the conditions that you can offer. Buy healthy, mature plants. Look at the orchid and learn about the type you have chosen.   What to avoid:   Impulse buying. Plants with obvious problems. Distorted flowers or leaves. Bug infestation. Looks unhealthy.

Part IV: I just brought an orchid home. Now what do I do?:

Part IV: I just brought an orchid home. Now what do I do? Variety of Orchid   Orchid type determines water needs and frequency of fertilizing. Common orchid species.   Growing Media   Type of media determines feeding, repotting, and watering needs. Common media types.   Location in Home   Location, location, location. Meeting the needs of the orchid.

Part V: Maintenance:

Part V: Maintenance Light   Inadequate light = Inadequate blooms. Most common reason. Too much is better than too little. Southern sunlight is best followed by east/west then north. Be sensitive to outside shading. Use a light meter when in doubt.   Growing Media   It’s media--not soil--and certainly not dirt! Types are many and limited only by availability, experience, and budget. Osmunda fiber, chopped tree fern fiber, bark, porous stone, and charcoal to name a few.  Select regional mix for best results.  Looser mix for thick roots and finer mix for thin roots.

Part V: Maintenance:

Part V: Maintenance Temperature Range is 55-80 degrees. Temperature drop at night and 24 hour fluctuation of 10-15 degrees are critical for blooming. Placement near windows/turning off artificial light will help this. Humidity NW Florida is almost ideal to satisfy 50% - 70% range. Paphiopedilum by R. Voelker

Part V: Maintenance:

Part V: Maintenance Cardinal Sin #1: Overwater. Cardinal Sin #2: Leave orchid in standing water. Allow media to dry before watering again.   Soak entire media completely until water comes out of drain holes.   Morning or afternoon is best to avoid excess watering. Use room temperature/slightly tepid water to avoid shock.

Part VI: Frequently Asked Questions:

Part VI: Frequently Asked Questions How do I get my orchid to bloom? Lighting. The best types of lighting.   When and how should I repot my orchid? Frequency. Growing media. Timing.   How can I propagate my orchid? Ways to propagate. What are the most recommended ways? Zygopetalum by R. Voelker
