What Can Cause Bumps on Orchid Leaves?
Bumps on orchid leaves can be caused by including pests, or due to Edema, and fungal or bacterial infections. It can also be caused by physical damage that can hurt the plant, and lastly, due to its natural growth developing as such.
Sometimes, bumps on leaves can be a sign of diseases or infections. However, this isn’t always the case, as other factors can also come into play. These other factors may include insect pests, environmental factors, or natural causes. It’s very important to examine your plant’s properly to determine the cause of the bumps, so you can be sure of the right course of action to take.
– Pests
Unsurprisingly, pests come up when you talk of common orchid problems. These pesky bugs have a way of showing up everywhere on plants, leaving behind terrible effects. Pests like Scale insects appear like brown spots on orchid leaves, giving the illusion of black spots. If you rub your leaves, then you will know you’re dealing with these insect pests.
Also, the feeding action of pests like spider mites, Thrips, Mealybugs, and scale insects can cause blisters on orchid leaves. Despite their small size, these bugs will suck the sap from orchid flowers and leaves, which can cause little bumps to appear over time. To prevent the bumps from appearing, you need to deal with the problem, which in this case is pests.
– Edema
Edema on orchid leaves is a condition that happens when your orchid’s roots absorb far more water than they let out through transpiration or when leaves take humidity from the atmosphere as opposed to transpiring. This causes a transparent pocket on the surface of the leaves that slightly resemble scales, and the closer you look and examine, you would see that Edema occurs due to your plant’s growing conditions.
Edema can occur in any orchid species, including heat-loving varieties like Phalaenopsis orchids or cool-growing orchids like Cattleya, as long as the plant is absorbing more water than it can transpire per time.
So, it’s safe to say that the root cause of Edema is overwatering. Although this condition is harmless to your plants, the blisters or bumps it causes can be unsightly that are bumps on the leaves of the plant.
– Fungal or Bacterial Infections
Another possible cause of bumps on leaves is fungal or bacterial infections, and you must know that these conditions occur as a result of an orchid’s poor growing conditions. Most times, the bumps that surface on your plant’s leaves are permanent.
However, in some cases, like when you have a scale infestation, the bumps you see are pests. The cause of the bump often determines if it’ll be temporary or permanent.
In addition to this, you would see that when you water the plant excessively, it provides a conducive environment for bacteria and fungi to grow. In the same vein, poor air circulation and excessive humidity cultivate the ideal conditions for these infections to thrive. If the infections persist on your orchids, you may notice bumps or elevated yellow or brown patches on their leaves.
Moreover, you will also notice that bacterial or fungal infections will adversely affect your plants. So, you’ll likely be dealing with two stressors; the infections and the bumps. While there isn’t a lot to do about the bumps, there are certain steps you can take to treat the infections and prevent them from growing on other leaves.
– Physical Damage
It’s possible for your orchid plants to get injured when you’re moving things around or when you’re changing their location. Accidental physical harm can cause insignificant bumps or elevated patches on the plant’s leaves.
While this might be a minor issue, the bumps will impact the plant’s overall appearance and its aesthetic development. It’s best to prevent or avoid physical harm to your plants as much as possible.
– Natural Growth
For many orchid species, slight bumps, rough patches, or raised areas on leaves are natural. These lumps are normal to their natural growth and are not deemed signs of health problems.
In fact, many of these wrinkles or bumps may be a defining aspect of the plant’s appearance, adding character and contributing to its distinctive beauty or appeal. So, if you notice bumps on your plant’s leaves, it isn’t necessarily terrible.

It’s best to protect your plants and keep them away from areas or items that can bump or scratch them. The general aim is to protect your plants from harm, so they don’t develop tiny bumps as a result.
In addition, when this matter is caused, and the bump left is a naturally grown one on leaves, it can appeal to some because nothing caused it, but this is how it grew, as you give it the right necessities to grow and develop.
