The Dypsis Decaryi, also known as the Triangle Palm, is a special and elegant plant from Southeast Madagascar. This palm is known for its unique growth habit in which the large, gray-green leaves grow in three directions when viewed from above, forming a triangle. With its exotic appearance and relatively compact size, the Dypsis Decaryi is a real eye-catcher in any interior or on the patio. This palm thrives best in a light location with sufficient air circulation and needs slightly moist soil. With the right care, this plant can grow into a beautiful eye-catcher and is certainly worth considering for lovers of special plants.
The Triangle Palm likes a sip of water
The Triangle Palm needs moderate to a lot of water to thrive. It is important to keep the soil slightly moist, but certainly not too wet. In the summer months, the plant will need more water than in the winter. Make sure that the plant does not dry out during dry periods, but also avoid that the roots are in wet soil for too long. It is advisable to regularly check whether the soil is moist enough, for example by feeling it with your finger. In addition, it is important to place the plant in well-drained and humus-rich soil, so that excess water can drain well and the roots do not remain wet for too long. By ensuring this simple water care, the Dypsis Decaryi will grow and bloom beautifully.
Summer
During the summer it is very important that this plant, when it is outside, is kept well moist. Especially during the warm days it should be watered every day, so that the root ball is well moist. On the less warm days this can sometimes be skipped for a few days. This is so important because otherwise the plant 'drinks' moisture from its leaves, causing it to become dry and eventually die. This should of course be prevented.
Winter
When winter is upon us, the rules are reversed! If the Triangle Palm is outside, it must remain dry so that the moisture does not freeze and damage the plant. The Triangle Palm does not suffer from a dry root ball during this period, it is in a kind of hibernation!
When the plant is kept indoors during the winter it should be kept slightly moist, so not soaking wet (as in summer), but just so that the root ball feels slightly damp.
General rules
In addition to the above guidelines, it is best to follow these rules:
First, give the plant a little water. If the soil is dry within 2 days, it means it needs a little more water. Adjust the amount of water until it still feels slightly moist between 2 and 5 days after watering, and almost dry after 5 days. If it feels very wet after 5 days, wait until it is almost dry and water again, but reduce the amount.
Spraying
We recommend that you spray the Triangle Palm with water weekly. However, we do not recommend this during warm summer days, so that you do it either in the evening after sunset, or on days when the sun shines little, because the water droplets bundle the incoming sunlight into small points that become very hot. These cause the leaves to dry out, or even burn through.
Aside from the detrimental effect of bright sunlight on wet leaves, misting has beneficial effects for your Triangle Palm. Namely, it removes dust from the leaves, allowing them to better absorb sunlight and appear more beautiful, and it deters certain types of pests.
Where is the best place to place the Triangle Palm?
The Dypsis Decaryi thrives best in a light location with full sun. This palm needs a lot of light to grow well and can also be placed on the terrace in the summer, provided it is slowly accustomed to direct sunlight. In addition, the Dypsis Decaryi tolerates temperatures down to -2 degrees Celsius, but it is advisable to keep the plant above zero. A moist soil is important for this palm, but it is important to prevent the roots from staying wet for too long. It is also advisable to fertilize the plant regularly from March to August. All in all, the Dypsis Decaryi is a beautiful and special plant that will certainly be an eye-catcher on your terrace or in your garden.
Light
The Triangle Palm is a plant that likes a fair amount of sunlight. It likes to be in full sun or half shade, taking in all the light. Is it indoors? Then it wants a spot near a window or where light comes in. The Triangle Palm requires at least 1 to 3 hours of direct sunlight per day
Wind
Make sure that the Triangle Palm experiences as little wind as possible. Wind can damage the leaves, causing them to die off more quickly. A little wind is not a problem.
Temperature requirements
Minimum 0 ℃ during the day
At night minimum 0 ℃
Repotting, why and when?
The Triangle Palm is best repotted once the roots begin to fill the current pot and grow out of the drainage holes. This may be necessary every few years, depending on the growth rate of the plant. Look for signs of rooting, such as roots emerging at the surface of the pot and slowing growth. Repotting is best done in the spring or early summer, when the plant is actively growing. Use a pot that is at least 20% larger than the current pot and provide good drainage to prevent waterlogging. With proper care and attention, the Dypsis Decaryi will continue to thrive and produce beautiful gray-green foliage.
General rules
When the Triangle Palm has taken root (often every 2-3 years) we recommend repotting it in the spring. If it is always inside, it does not matter. If it is outside, it is not a problem to repot it in the summer, but we advise against it in the fall and winter, because it will not grow and take root optimally. This can make it somewhat weak, and it may suffer damage from frost.
When you choose to repot your Triangle Palm, choose a nice pot that is twice the size of the root ball. Place a layer of hydro grains at the bottom of the new pot for better moisture control. It will be grateful for that. Fill this layer with some Mediterranean potting soil. This type of soil ensures that the Triangle Palm roots optimally and is fed. Then you can place the root ball on the ground. Make sure that the top of the root ball is slightly below the edge of the pot. Aim for a difference of 2 to 6 cm. This difference ensures that the water does not run off the root ball when you water it.
Every year you should replace the top layer of soil, because it hardens and 'wears out' in nutrients, due to regular watering and because of the sunlight on the upper edge of the root ball.
Provide the Triangle Palm with good nutrition
The Dypsis Decaryi does not have many special nutritional needs. A light, well-drained and humus-rich soil is ideal for this plant. It is important to fertilize the plant once every two months from March to August to ensure that it receives all the necessary nutrients. During dry periods it is important to ensure that the soil does not dry out, but it is also important to prevent the plant from standing in soil that is too wet.
It is an easy plant to care for and can be kept both indoors and outdoors, as long as it has sufficient light and air circulation. The Triangle Palm is drought resistant, but a slightly moist soil will ensure better growth. All in all, the Dypsis Decaryi is a beautiful and striking palm plant that can be a real eye-catcher in the home or garden with the right care and nutrition.
Diseases and pests
Although the Dypsis Decaryi is generally not affected by diseases and pests, there are still a number of problems that you should take into account. One of the most common diseases in this palm is the so-called leaf spot disease, which is caused by fungi. This disease can lead to brown or black spots on the leaves and can affect the general health of the plant. To combat leaf spot disease, it is important to remove affected leaves as soon as possible and ensure that the plant is in a well-ventilated place.
Another problem that Dypsis Decaryi can face is the presence of spider mites. These small insects feed on the sap of the plant and can lead to yellow spots on the leaves and a general weakening of the plant. To combat spider mites, you can regularly spray the leaves with water to wash the insects away. In addition, you can also use natural pesticides such as neem oil to remove the mites.
In addition to leaf spot and spider mites, the Dypsis Decaryi can also suffer from mealybugs, which feed on the sap of the plant and cover themselves with a white, fluffy substance. To combat mealybugs, you can clean the affected leaves with a mixture of soap and water, or use natural enemies such as ladybugs that eat the mealybugs.
It is important to regularly inspect your Dypsis Decaryi to be able to discover and combat any diseases and pests in time. By giving your palm plant the right care and attention, you can ensure that it continues to grow healthily and beautifully and enjoy its beautiful appearance in your garden or on your terrace. With the right preventive measures and timely interventions, you can ensure that your Dypsis Decaryi continues to shine healthily for a long time.
How and when should you prune the Triangle Palm?
The leaves of the Triangle Palm will eventually wither. If this is the case with a leaf, you can simply cut the stem near the trunk. It is not a problem to cut off an entire leaf with the stem of the plant. This is the way the plant forms its trunk.
How can I propagate the Triangle Palm?
The Triangle Palm can be propagated by seed. The seeds should first be soaked in lukewarm water for 2 to 3 days and regularly refreshed to prevent mold formation. The seeds can then be planted in an airy sowing mixture of perlite, coco peat and coarse sand. Keep the soil slightly moist and place the sowing in a warm place between 25°C and 30°C. The seeds can germinate between 2 weeks and 3 months. With the right care and attention, these special palms can be propagated yourself.
