Philodendron Weeks Red is a unique hybrid that originated in Miami, United States. It was crossbred by Ron Weeks, an American botanist.
This magnificent plant has gigantic emerald-green leaves that have red streaks on them. New baby leaves are strawberry-colored with pink mottling. These change to yellow, lime-green, and then emerald-green as they mature. These leaves are 4 to 5 feet long and triangular-shaped.
This plant blooms when provided with ideal growing conditions, for example, its natural habitat. Therefore, you will rarely see it produce flowers indoors, even in the growing season. In its natural habitat, it produces white-colored inflorescence.
It attains a mature height of 3-4 feet when given favorable growth conditions.
Philodendron Weeks Red Care
Philodendron Weeks Red prefers humidity above 60% and temperature above 12°C. The highest temperature it can tolerate is 26°C. Other care requirements for this plant include once-a-week watering and tri-yearly fertilization. It should be placed under partial sunlight or dappled shade for proper growth of its foliage. Moreover, it should be grown in loose, organic, and rich potting soil.
|Watering||Once a week|
|Soil type||Well-draining, organic, rich soil.|
|Sunlight||Partial or dappled shade (70-85%)|
|Temperature||12°C to 26°C|
|Fertilizer||A slow-release fertilizer three times a year|
|Pruning||One to two times a year|
Like most Philodendrons, Philodendron Weeks Red needs hydrated soil to stay alive. Keep in mind hydrated soil is different from wet, mushy, and damp soil. Too much over-watering can kill this plant even if the other growing conditions are perfect. The reason is that overwatering leads to root rot which is one of the most common causes of plant death.
To ensure that you do not overwater, always let the soil dry between waterings. Stick your index finger into the soil till your first knuckle. If it comes out with soil, do not water your plant. It means the soil is still moist.
In the growing season, you can water this plant once every week. Decrease the watering frequency during winters.
The secret to a healthy plant is good soil. So, let us tell you the ideal potting mix for this Philodendron hybrid. This plant likes loose, well-draining soil. But the soil should not be so loose that it cannot hold water. It should be able to retain the necessary amount of water and drain the excess water at the same time.
A peat moss-based soil works best for this Weeks Red Philo. It has an airy and coarse texture. The airy texture is responsible for the aeration of the soil, while the coarse texture helps the soil retain water.
This plant prefers dappled to partial shade to grow properly. Direct sun can burn its leaves and eventually kill the plant. Similarly, too little light exposure is bad for this plant’s foliage. Low sunlight exposure leads to droopy foliage and outward arching stems. Therefore, you must ensure your plant gets 70-85% sunlight exposure every day.
The north and east-facing windows are perfect for its placement. But if you have a south-facing window at home, place your plant at least 6 feet away from it. You can also use artificial lights. 12-hour exposure to artificial lights is necessary for this plant’s proper growth.
Like all other tropical philodendrons, for example, Philodendron McColley’s, Philodendron Painted Lady, and Philodendron Burle Marx fantasy, Philodendron Weeks Red grows best in warm and humid surroundings. This plant prefers a temperature range of 12°C to 26°C to grow indoors. It cannot tolerate temperatures below 10°C. Therefore, you have to keep it in a warm, cozy place on a chilly night; otherwise, it will get cold injuries.
If you want your gorgeous Weeks Red Philo to produce large, shiny, and healthy leaves, you must maintain the humidity levels around it. It is a humidity-loving plant. Humidity levels above 60% are the best way to keep its foliage healthy and shiny. Although it can tolerate low humidity levels, it thrives in a highly-humid environment.
A popular way to increase humidity for this plant is to mist its foliage twice every day. But this practice also puts the plant at the risk of getting a pest infestation. Therefore, you should spray the plant monthly with a pesticide to kill any possibility of a pest attack.
There are two types of fertilizers that you can use for this plant. One is a slow-release fertilizer. It dissolves in the soil slowly and is available for many months. Therefore, it needs to be applied only thrice a year.
The second type of fertilizer is liquid fertilizer. It is readily available to the plant and thus readily finished too. Therefore, it needs to be applied 1-2 times every month during the growing season.
Whichever fertilizer you use, make sure to dilute it to half its strength and add it 6 inches away from the base of the plant.
This handsome plant with gigantic leaves does not need any pruning unless you want to control its size. If you like it to take all of the available space in your room, you should let it grow and not cut it back.
However, you still need to cut its old leaves from time to time. Cutting dead, old, and yellow leaves increases the plant’s growth rate. Therefore, it is a healthy habit. The only thing you need to keep in mind is never pruning the plant during the growing season.
