The Swiss cheese plant (Monstera adansonii) gets its common name from its large, heart-shaped leaves that develop holes as the plant ages, making the leaves resemble Swiss cheese. It can be trained to grow up a moss poll, but it looks great when left on its own to grow long vines.
Like its cousin Monstera deliciosa (also sometimes referred to as the Swiss cheese plant), monstera adansonii grows quickly, with an average growth rate of one to two feet per year in ideal growing conditions. Kept as a houseplant, itll grow to between 3 and 8 feet long; in its native habitat, it can grow up to 13 feet.
Its important to note that all parts of Monstera plants are toxic to pets, so be careful when growing them indoors.
Ivy is a beloved outdoor plant, known for its ability to scale walls and provide ornamental appeal. However, ivy owners may notice mysterious holes appearing in the leaves, which can be alarming. What causes holes in ivy leaves, and what can you do about it?
What Causes Holes in Ivy Leaves?
There are several potential culprits when it comes to holes in ivy foliage:
-
Insects – Common ivy pests like caterpillars, beetles, leafcutter bees, and leaf miners chew holes in leaves. Look for signs like skeletonized areas, perfect circles, winding tunnels, and small notches between veins.
-
Slugs/Snails – These gastropods leave behind ragged notches in leaf edges and slimy trails on plants overnight as they feed.
-
Disease – Foliar diseases like anthracnose and shot hole can first appear as leaf spots, which then spread into holes.
-
Environmental factors – Issues like hail damage, sunscald, and nutrient deficiencies can also potentially cause holes.
Carefully inspect leaves to determine what may be causing the damage. Capture any insects found for identification.
How to Prevent Holes in Ivy Leaves

-
Remove weeds that harbor pests from around ivy plants.
-
Apply 2-3 inches of mulch to suppress weeds and slugs/snails.
-

-
Use row covers to exclude pests but allow airflow.
-
Apply biological controls like beneficial nematodes.

How to Treat Pest Problems on Ivy

-
Remove heavily infested leaves and stems to eliminate pest habitat.

-
Spread diatomaceous earth to deter crawling insects.
-
Trap slugs and snails using beer-baited containers sunk into the soil.
-
Improve airflow and use sulfur powder or horticultural oils to treat mites and diseases.
Always follow label directions when using organic pest control products.
Will Ivy Recover from Pest Damage?
In most cases, ivy will bounce back after periodic pest attacks. As long as the main stems are intact, new leaves will generate over time.
To help ivy recover:
-
Prune away extensively damaged leaves and stems.
-
Provide supportive trellising if needed until regrowth establishes.
-
Apply organic fertilizer to stimulate new growth.
-
Keep ivy well-watered while regrowing.
-
Monitor for recurring pests and quickly treat any new holes.
With prompt treatment and attentive care, ivy can fully recover from minor to moderate pest damage.
Preventing Further Issues
The most important step is preventing extensive pest damage in the first place by:
-
Choosing more pest-resistant ivy varieties like duckfoot, butterfly, or collegiate ivy.
-
Providing ideal growing conditions including proper light, water, humidity, air circulation, and nutrition.
-
Monitoring plants vigilantly each week for early signs of pests.
-
Applying preventive measures like horticultural oils and insecticidal soaps before infestations take hold.
-
Responding quickly at the first sign of holes with organic treatments.
Healthy, vigorous ivy better withstands occasional pest attacks. Stay on top of care and inspection to avoid major holes in your ivy leaves.
When to Seek Professional Help
For severe ivy pest infestations, seeking professional advice may be warranted. Consult an arborist or horticulturist if:
-
You cannot successfully identify the culprit pest.
-
Damage is rapidly spreading.
-
Recommended organic treatments are ineffective.
-
The ivy suffers over 30% defoliation.
-
The plant’s main stems and branches are compromised.
-
The ivy fails to recover within several months.
Experts can pinpoint tricky pest issues through inspection and offer treatment guidance. They may advise pruning severely damaged ivy or using professional-strength products. This provides the best chance of saving extensively infested ivy plants.
Enjoy Pest-Free Ivy
Don’t let mysterious holes detract from the beauty of ivy. With vigilance and prompt organic care, ivy can continue flourishing. Check plants routinely, act at the first sign of pests, and help ivy regain its vigor after damage. A healthy ivy will keep climbing walls and draping fences hole-free for years to come.

Is your Adansonii a Wide or Narrow Form?
Monstera Adansonii is typically found in two forms – wide leaf form or narrow leaf form. Both forms of this plant require the same care. It can be difficult to see the difference in juvenile plants but as the plant grows to maturity it will be quite apparent. Narrow form leaves may have less fenestrations than wide form and the immature ones may show no fenestrations at all. On the narrow form leaf, the shape is much more pointed and lance-like. On the wide form, the shape is much more round. Both forms require the same care and will grow in the same manner.

Should your Monstera Adansonii Climb or Hang?
Monstera Adansonii is a vining plant which, in the wild would use it’s aerial roots to find a tree to climb. As the vine climbs it will begin to receive more light and will grow larger and larger leaves in response. You can choose to encourage your plant to climb by giving it support like a trellis or pole but be warned, keeping an eye on this plant is important whether you allow it to climb or leave it to trail. It’s going to do what it naturally does no matter what you might wish it to do. Mine quickly outgrew it’s trellis and, after finding the wall behind it, attached to the surface and began to climb up it.
I will say, it looked amazing and natural that way however, the vines will cause damage to the paint and drywall if left to do their own thing. Be aware that if you allow your plant to climb your walls, you will likely have a home repair job in your future.
If you leave your plant to trail it will be doing the opposite of what it likes to do in nature. This may result in smaller leaves with less fenestrations which is fine. It won’t hurt the plant. Just know that if you want a big leaved, jungly looking plant, allowing it to climb will get you there.
