Do not leave your plant in a cold draft or near a cold window or a fan heater
Do not leave your Monstera in direct contact with the sun
Do not overwater it or let it dry out
Do not leave the roots in constant contact with water for an extended period of time
Just relax and enjoy it
It will grow fast very quickly
Light and Location
Monstera prefers diffused bright light. Place it in either a bright room with indirect sunlight or a bright room with plenty of shade. Its growth will decrease if your plant gets too much shade. The leaves will grow toward the light. Too much sun will scorch the leaves.
In their natural habitat, they climb trees and gain shade and moisture from them. You will have to find the right balance between light and shade. Signs for lack of light are small and weak leaves and thin air roots.
Turn your plant every two weeks, for your plant to have an uneven shape. If you don’t, your plant will grow toward the light.
Ensure that your water is at room temperature. Allow the soil to dry for a couple of inches before watering again. Watering once a week is the right watering balance. They do not like to have their feet wet. Water sparingly to make the soil barely moist, but not wet.
Temperature & Humidity
The ideal temperature for a Monstera is between 18-29℃. They can survive in temperatures as low as 10℃, but it won’t grow. If the temperature is above 16℃+, your plant will continue to grow. Below 15℃, the growth rate slows down, and you will need to water less. Our home temperatures have the ideal climate for a Monstera Deliciosa.
Do not leave your plant near cold draft or a cold window.
They like to have humidity around them. Usually our homes are do not have a high level of humidity. If your home is too dry, you can mist the leaves, or you can make a humidity tray. Make sure the roots are not in contact with water for a prolonged period.
Repotting & Compost
You can repot your plant every couple of years. If you want to slow down its growth, take some of the soil out and top up your soil. The more you repot, the bigger your plant will become.
Gently work the old soil out of the roots, to help them spread out in the new pot. Try to take as much old soil out of the roots. Place your plant in a new pot with gravel at the bottom for drainage, fill around the root ball with fresh soil.
Monsteras need a soil well drained soil. The ideal soil is peat soil mix with vermiculite.
My potting mix is:
10% agricultural charcoal
10% vermiculite is good for drainage
80% Westland compost.
This is my personal preference. It works for me. As long as you have drainage in your compost, your plant will be happy.

During the growing period, from the end of March to end of October, feed once a month with fertiliser. Once established, they require less fertiliser.
I use Happy House Start Me Up (in addition to RootGrow when I repot). It is completely natural and there is not risk of overdose. Just add to the surface of your plant, lightly fork and water as usual. Remember, do not over fertilise your FL and always follow the guidelines of the fertiliser you are using.
Propagating this plant is such an easy process. Spring/Summer is the best time to propagate a Monstera, but you can achieve it at other time of the year.
Cut a stem with 2 or 3 leaves at the root node, with a root at the bottom if possible. Place it in water or in moist potting soil easy to drain. You should see results in a few weeks depending on the time of year. Transplant the plant into a pot when you notice roots appearing. It is an easy process.
There is no rule. You can leave your plant be or cut the stems to change the shape of your plant.
If you want to propagate, make sure you cut a stem with a root attached.
Cut any yellow leaves.
Cleaning the leaves
Gently clean the leaves regularly to get rid of dust, bearing in mind that they are delicate.
Trunk & Growth
If you have a mature plant, it will require support with a moss pole to support its weight and to grow tall. You can use any stick to train your plant. If your plant is small, it is not necessary to have a support pole. If you are using a moss pole, mist the moss from time to time to encourage the aerial roots to take hold.
In their natural environment, they climb trees to get support and use their aerial roots. If your plant is small, it is not necessary to have a support pole.
Monsteras are famous for their large green glossy leaves. A juvenile Monstera starts with full leaves with no slits. When the plant matures, the leaves grow larger and begin to have a slit.
The Monstera Deliciosa is often called “the monster” due to its rapid growth. If you want to keep your plant controlled, do not repot it too often as it will shoot off.
A mature Monstera can develop a large number of unruly roots. You can cut them or put them back in the soil. If the roots are outside the pot, they won’t damage your wall or wallpaper.
Tips of leaf and edges turning brown is a sign of root bound, and it needs repotting. It could also be a lack of humidity.
Leaves not getting slits is potentially due to lack of light.
Yellow leaves could mean that you are overwatering your plant or it does not have enough nutrients in the soil.
Brown leaves indicate that you are overwatering and the roots are rotting. remove your plant from the pot, remove the wet soil, leave the roots dry out of the pot for 24 hours. Repot into a clean pot with fresh dry soil. Place your plant in bright indirect light. Go easy with watering until your plant has recovered.
Powdery mildew can kill the leaves’ tissue. You will end up with your leaves dropping and your plant not growing. You can resolve this problem by using an organic fungicide or wash your plant with a damp cloth and a drop of washing liquid.
If your plant has pests, put it in quarantine before it spreads to your other plants. Monsteras are resistant to pests. Usually, they can be infected by surrounded plants.
Spider mite is a small red spider. Pale spots on the leaves appear. Use a fungicide to clear it.
Mealybug looks like lumps of cotton wool, and they live at the bottom of the leaves. The plant will start by losing its leaves. Spray with a fungicide and repeat the 1 week later until your plant is cleared.
A good tip to clear your plants from pests is to use a damp cloth with a little washing liquid. Clean your leaves and do it again every week until it has resolved.
I had whiteflies, last summer, and I cleaned the leaves and trunk thoroughly with a damp cloth and a drop of washing liquid. I rinsed my plant and followed the same process a week later. Furthermore, I used a fungicide between cleaning. My plant has survived but brown scars have remained with brown spots on the leaves.
If you have pests, put your plant in quarantine until the problem is resolved.
