Orchids and their place in the landscape
In this article, we will be looking at orchids and their place within the landscape.
There are many species of orchids that are beyond the scope of this article so we will be looking at some basic information about orchids, i.e. how to care for them and place them within the landscape. Orchids are in my opinion very exotic plants that can really add that elegant touch or flavor to our landscapes or interior plant scape.
I have worked with orchids over the years using them in many plant designs. I enjoy working with orchids because orchids can give that soft touch and appeal that can get the attention of just about anyone with their bright beautiful showy flowers.
Use of orchids in interior design
Many years ago I worked at a five- star hotel as an interior plant scape designer and had the privilege of working with many orchid varieties that included dendrobiums and phalaenopsis.
Adding these plants to arrangments with their many colors brought a delightful transformation to every space.

These are just a few of the many colors that you can add to your home/office to brighten up your surroundings. Dendrobiums can also be used on the exterior by attaching them to trunks of trees with fishing line or some persons use nylon women’s hosiery.
Dendrobiums Growing on a tree
This is a unique way that orchids can be used to bring beauty and color into the landscape. It is so amazing that these plants can attach to the trunk of a tree with their roots and survive for a very long time.
Dendrobiums have the ability to draw moisture from the air. That is why orchids are known as ‘air plants’ being able to draw all the moisture that they need from the air.
How to train orchids to attach
Supplies you will need are:
- Fishing line.
- Spanish moss.
- 32oz spray bottle filled with water.
- Pruner or butter knife.
- Someone to assist.
Care of Dendrobium indoors
Instead of soil, sphagnum moss is used to grow orchids. Make sure that the sphagnum moss is somewhat moist, not too wet and not too dry. Mist the leaves as needed with water. From time to time you can also mist the sphagnum moss with water.
Phalaenopsis orchids can also give that ‘wow’ to your landscape design. I have also worked with these over the years and I have seen them in so many color varieties. In my opinion, Phalaenopsis gives a softer and elegant appeal.
Taking care of phalaenopsis is the same as taking care of dendrobiums. Phalaenopsis should also be handled with care because they can be damaged very easily.

These are just a few of the many colors that you can choose from.
Mist the plant leaves enough so that plants can get the right amount of water. Orchids that are exposed to air conditioning do not need as much water because of the cold that they are allowed to grow in. Make sure that your orchid plants get sufficient light. Like other plants, orchids also need some light. So placing them by a window or making sure that the room they are in has the right amount of light is a necessity.
Pests and disease control for orchid plants
As beautiful as our orchids maybe growing, it is always good to be on the lookout for insects and disease that can cause these plants to drop leaves and in some cases die.
Therefore it is good to have an inspection program where you inspect your plants at least twice a week, so if there is any problem you can take care of it before it becomes major.
Orchid plant pests
Some of these pests include scales, aphids, mealybugs, whiteflies and spider mites. You can treat these plants by using insecticidal soap. Be sure and follow direction. With a spray bottle knock the pests off with a strong spray of water.
These insects will suck the juice from your orchid plants. The excrement from these insects is sugary and sticky which is called honeydew. This is followed by a black mold that forms on your plants due to this honeydew.
This black mold will not only cause your once beautiful plant to lose its beauty but if left unchecked your plant will eventually die.
To prevent this, use cotton swabs dipped in rubbing alcohol to be applied to the affected areas or apply neem oil.
Diseases affecting orchid plants
Disease issues are another thing that we must deal with or try to avoid when caring for orchids. If you are faced with this challenge, there are measures that you can put in place to combat this problem.
While discussing orchid plant disease is beyond the scope of this article because of its vastness, we will be looking at some of these measures in other articles that will teach you more in depth.
Causes of orchid plant disease
Orchid plant diseases can be brought on by warm and moist conditions. Sometimes the aspiring gardener may use an infected tool on the plant without sterilizing it.
Diseases are caused by plant pathogens such as virus, bacteria, and fungus. Therefore it is important that we do not create situations that are favorable to them.
When watering orchids do not over water your plants. Try to always water plants during the day so it has time to dry out before nightfall. The sphagnum moss that the orchid grows in, should be somewhat moist and not waterlogged.
Make sure that the pot your orchid is in has good drainage because if your pot does not have proper drainage and your plant is allowed to sit in water, the leaves will turn yellow causing the plant to experience leaf drop. So make sure that the pot you use has sufficient drainage holes.
Another way to avoid orchid plant disease is to make sure to provide good air circulation for your plant.
Orchid diseases consist of:
1. Bacterial leaf rot
2. Crown Rot
3. Bacterial root rot
Leaf rot causes the leaves to slightly discolor. If you allow this to persist the spot will become larger. The infected part will turn gray and then soft.
Remove the infected part of leaf back to the sound tissue with a razor blade, sharp pruner or scissors. Treat the sound part of the leaf with a bactericide
Crown rot: Crown rot attacks the uppermost leaves. The uppermost leaves become soft at the attachment point to the plant stem. Remove the uppermost leaves then treat the infected area with a bactericide.
Bacterial root rot: Bacterial root rot is caused by overwatering. When this occurs some of the lower leaves will show signs of shriveling, then the infected roots will become dark and soft. Treat the plant by cutting off the infected part of the roots and change the potting soil medium.
In the process of treatment, do not water the plant for a week and then water plant less than you did originally.
Leaf burn: Leaf burn happens when the plant is overexposed to sunlight.
Black spot: Black spot is caused by a lack of fresh water or too much fertilizer. Black spots will appear on the leaves so make sure that your plant gets good circulation.
Bud blast: Bud blast occurs either with the bud in the sheath, or when the orchids emerge as buds. This happens when you move your orchids from one environment to the next. Because of the change in temperature and lighting the buds in the sheath develop a bacterial rot. Sometimes the buds in the sheath turn black.
Due to the fact that moving your orchids from one place to the next can cause bud blast, just wait until the flowering buds on your orchids open before moving them.
Follow these tips and you will have beautiful flowering success.
