After you've stocked up on hurricane supplies and prepped your home in advance of a storm, you will likely want to turn your attention to your orchids and other plants if there is time. After all, some collectors have invested a significant amount of time and money into their orchid collections.
Tips for Your Orchids
Relocate and Secure Your Pots
In addition to structural damage, hurricanes can do a doozy on your landscape --- especially your orchids. We’ve assembled a few quick tips to help avoid further damage after a hurricane.
Too Much / Too Little Sunlight
If a storm causes you to lose trees and branches that previously provided filtered light for your orchids, be sure to relocate your orchids to a shadier spot as soon as possible to avoid orchid sunburn.
If you took your orchids indoors before the storm, make sure they are still receiving plenty of filtered sunlight. Often times, growers will move their orchids into a garage or bathroom to keep them protected but end up leaving them "in the dark" for too long while tending to other post-storm tasks.
If your orchids were exposed to saltwater associated with storm surge, it’s really important to flush your pots with fresh water. Saltwater can be very damaging to orchids. Salt, in a concentrated form, is a type of herbicide. The sooner you can clear the saltwater from your plants, the better your chances of saving them.
Too Much / Too Little Water
If your area received a lot of rain, check your outdoor pots to look to see if they are draining properly to avoid root rot. Drain holes may be clogged with debris and plant saucers may need to be drained. These efforts will also help to reduce breeding grounds for mosquitoes.
If you relocated your orchids indoors before the storm, don't forget to keep them hydrated. The air in your home is less humid than outdoors. Try misting them often until you can move your plants outdoors again.
Hurricane stress isn’t just for humans, orchids can experience it, too. Watch for signs of fungus and bacteria. When a plant is weakened from changes in the environment, they are more susceptible. Treat at the first sign of fungus or bacteria and keep your sick orchids isolated from your healthy ones.
Understanding the natural growing habitats of orchids helps us to understand where they should be happiest in our home. In nature, most orchids grow in tropical climates with lots of humidity, ventilation, and filtered light. Here are a few tips for growing orchids indoors and outdoors.
Finding the Perfect Indoor Spot
Find a window that provides good filtered light throughout the entire day. In nature, most orchids grow in trees or within the landscape under trees and get filtered light from daylight until dark. Make sure the light your orchid receives is filtered with a sheer or screen. Don’t place a plant in a window with direct light as glass can actually intensify the light and cause burn.
Orchids do well in bathrooms as they provide plenty of humidity. However, not all bathrooms have a window which is needed to ensure proper lighting. If you don't have a sunny window, grow lights are an alternative option.
Also remember that humidity levels are important when growing indoors. Your air conditioner and heater are designed to remove humidity from the air. So you will need to provide additional humidity by misting your plants daily. Another alternative is to create a water reservoir with pebbles and a shallow dish filled with water to the top of the pebbles. By setting your orchids on top of the pebbles, your plants won't sit directly in the water - but humid air will rise around the plant to provide the humidity your plants need.
Outdoors with a view
Back porches, lanais or pool areas provide a great growing environment for your orchids. Just remember to place your orchid where it won’t receive direct sunlight. Be sure to check the light levels throughout the day as shadows and light patterns may change from the morning to the afternoon.
Typically, an outdoor environment provides natural humidity, but it’s still a good idea to keep an eye on the weather. During certain times of the year, the humidity can be very low and you may need to mist your plants. Also pay close attention to the type of orchids that you are growing. For example, vandas often require daily waterings.
Another benefit to outdoor growing is natural ventilation. However, during certain times of the year, the wind may be stagnant. Most plant diseases and insects thrive in hot, stagnant areas. A simple box fan can provide the circulation needed to keep diseases and insects at bay.
While the information above offers good rules of thumb (a green thumb!), keep in mind that different types of orchids have different requirements. To learn how to care for specific orchid varieties, visit our common orchid varieties page for more details.
What potting mix is best for growing orchids? Bark, moss, lava rock? Well, the answer depends on the type of orchids you are growing, the location of your orchids, and how you care for them.
For example, if you're in an area with a very dry climate, you should select a mix that retains moisture. If you grow your orchids indoors and tend to over water your plants, you will want potting mix that drains well. So how do you know which mix retains moisture and which ones do not?
First, let’s look at the ingredients found in orchid potting mixes and their specific traits:
Of course, we don't expect you to find these individual ingredients and make your own orchid mix. Thankfully, our head grower applied his many years of research and experience to develop our line of Better-Gro Orchid Potting Mixes. The following products are the exact same mixes that we use in our greenhouses to grow thousands of plants each year.
Summer is a time when fungal infections can quickly spread through your orchids. Fungi thrive in warm, humid conditions which coincidentally are the same conditions that most orchids need to survive. So, whether you are a greenhouse grower or your orchids are grown outside, you need to be vigilant about watching for the first signs of an infection. If left untreated, a fungus can kill your plants. But don’t worry, follow these instructions below to help detect, treat and prevent to bring your plants back to good health.
Let’s talk about the most common types of fungi that may impact your orchids:
Botrytis causes small brown spots on your flowers, ruining an otherwise beautiful flower. As the fungus spreads, you will notice more spots that are larger in size.
Use a fungicide such as Physan 20, Daconil, Thiphanate Methyl according to the product directions. For a less toxic option, you may also use Hydrogen Peroxide in a spray bottle. You should know that spraying a fungicide will help control the fungal problem, but may also spot a flower or brown the edges.
Improve the air circulation around your plants and remove dead plant materials (expired blooms, old pseudobulbs and dead leaves). Avoid watering flowers, and water early in the morning to allow plenty of time for excess water to be absorbed or evaporated. Also, monitor night temperatures and avoid dips below 60 degrees when possible.
We hope you never find evidence of these fungal infections among your orchids. However, know that if you do catch it early, you can save your plant before it is too late.
Remember to keep a clean growing environment, remove dead plant debris, allow for proper air circulation and water plants early in the morning. These simple suggestions will help keep the fungi away.
Happy Blooming from Better-Gro!
If you keep your orchids outdoors during the summer to take advantage of the rainy season and warm weather, be careful that your plants aren’t receiving too much of a good thing. Orchids are natural epiphytes that derive water and nutrients from tree canopies. Their native settings allow plants to soak up just the right amount of rain, shed unnecessary water and allow roots to dry out between rain showers.
Despite our attempts to mimic an orchid’s natural setting, an outdoor potted orchid needs extra care and attention to avoid receiving too much water.
All orchids are not the same. Some varieties prefer to dry out completely between waterings such as vandas and phalenopsis (moth orchids). Other orchids such as paphiopedliums (lady slippers), miltonias (pansy orchids) and cymbidiums like to stay evenly moist but not soggy. Orchids that like something in the middle - evenly moist during high growth periods but dry outs between waterings - include cattleyas, dendrobiums and oncidiums.
What Is the Harm in Too Much Water?
There is such as thing as “too much of a good thing” as it relates to rainwater and your outdoor orchids. Without proper drainage, too much water can literally kill your plant. Overwatering can deprive your orchid roots of oxygen. In a short period of time, your healthy green or brown roots will turn black and begin to rot. This wet environment is ideal environment for bacteria or fungus. If you aren’t careful, the damage caused to your roots will eventually show in the leaves of your plants. By then, unfortunately, it may be too late to save the plant. So take the time this summer to routinely check your outdoor orchids to be sure they aren’t getting too much of a good thing with these summer rains.
