Monstera Adansonii 

Monstera Adansonii leaf with holes

These unique somewhat rare plants are a conversation starter for sure! There are two forms of the Adansonii, the "Wide" form & the "Narrow" form. The Photos area of a "Wide" form. These originate in warm, humid Mexican rainforests where they are found growing up the trunks of trees searching for light. They use their aerial roots to grab onto whatever they can to support them absorbing water and nutrients from the air and moss around them. As they use these roots, they stimulate the plant to grow 13 feet or more and the leaves can get up tp 10 inches long! They have fenestration with each new leaf that is actually an evolved advantage. In the wild strong winds and rain will destroying plants, causing sever damage. The Monsteras evolved these splits (fenestration) to help pass winds and rain through their leaves minimizing the surface area for the elements to damage their leaves. Cool right?! Even though they look advanced, they are a very forgiving plant and a fantastic option for apartment living.

 

Lighting:

These require bright indirect lighting, to bright filtered lighting. The Adansonii can handle lower light conditions for short periods of time before they become stressed.  Some will say their Adansonii does fine in little to know light however, we have been growing these for years and noticed under low light conditions, they start to stress slowing their growth and causing the new leaves to become thin and warped. 

Water:

Try keep the soil moist but not soggy at all times, generally a weekly water will be just fine. Try avoid the roots to stand in water for too long as they don't like "wet feet". We notice that if they do dry out for too long they seem to temporarily stunt their growing.  

Soil:

These prefer a chunky soil that still retains moisture but still fast draining. Generally an Aroid mix will work just fine. You want to keep the soil moisturized not soggy, as these do poorly when the soil drys out. We use a mix of coco coir chunks, ground coco coir and perlite. 

Fertilizer: 

Choose a high quality balanced water-soluble fertilizer which you can use in every watering. This will get the plant to really take off and get to a larger size, especially during its growing season. 

Temperature:

These prefer an average room temperature around 65-85 degrees.  Anything below 65 and your Adansonii will become stressed and the leaves will turn yellow.

Humidity: 

These thrive in higher humidity, around 50-80% will help prevent the leaf tips from browning and protect the aerial roots from drying out. If your climate is dry, misting 1x-2x a day will make it feel right at home.

Containers: 

In general, any material will work just fine for the container you are using, just make sure it has drainage holes at the bottom. If they don't you can drill a hole at home. For the most part they can handle being root-bound for a short periods of time, but ideally repotting at least 1x a year. Rule of thumb, is sizing up one size each time you are repotting. This is crucial for root health and growth development.

Common Pests:ÔĽŅÔĽŅ

The most common pests you would encounter with the Adansonii would be Spider Mites, Fungus Gnats, Thrips, Scale and Mealy Bugs. A great way to "scout" your plants, would be a weekly leaf inspection with diluted Neem oil on a paper towel. Use the paper towel to wipe down the fronts, and backs of the leaves to help prevent or treat pests on your plant. Doing this weekly will help catch signs of bugs early on and keeping them under control.

Troubleshooting:

Yellowing leaves are signs of overwatering and/or insufficient nutrients. Try checking soil to make sure it isn't to wet and try fertilize more frequently. Browning leaves are signs of too much sun exposure. These need bright indirect light or bright filtered lighting. Try place your Adansonii in another location in your home, or try hang it in a plant hanger. Another cause for browning leaves could be over fertilizing. Try skip the next few time you plan to fertilize or dilute the fertilizer in water.

Maintenance:ÔĽŅÔĽŅ

 Maintenance: Try keep a consistent watering schedule and daily listings as these will drastically help maintain a beautiful healthy plant. Always remove yellow or dying leaves. Inspect your plant(s) at least 1x a week "scouting" for any signs of pests or disease, follow up with a neem oil leaf treatment. Try to flush the soil 1x a year to avoid salt and mineral buildup, as this will prevent the roots from burning. Always repot 1x a year, always upgrading one or two inches wider/deeper then the one it was previously in. Overall, this is a great option for anyone living in apartments or wanting to add something unusual to your collection!
