Coffee plants produce beautiful green leaves that turn brown as they grow. The process is completely natural and can be a bit confusing for those who don’t know why it happens. In this post, we’ll discuss 3 reasons why do coffee plant leaves turn brown and what you can do to help keep your plant healthy!
Why Do Coffee Plant Leaves Turn Brown
The leaves on your coffee plant may turn brown and fall off for a few different reasons. Direct sunlight can scorch the leaves, as well as fungal diseases like leaf spot disease which can be fatal to the plant.
HARDINESS AND COLD DAMAGE
Although coffee plants are indigenous to Ethiopia, they grow best in subtropical and tropical climates. The vast majority of these plants thrive when temperatures fall between 70-80 degrees for daytime and 60-65 degrees for nighttime. Although the plant can withstand a brief spell at 40-45 degrees without dying, anything below 55 should probably be avoided. Coffee plants have evolved to be cold-tolerant but can only withstand a certain amount of heat and sunlight.
FUNGAL LEAF SPOT
Brown spots on leaves are a common fungal disease caused by Cercospora. These brown spots can be surrounded by a light yellow halo, which creates an eye-like appearance.
If you want to manage leaf rust, remove all fallen leaves and debris. Thoroughly remove weeds from around the plant and prune branches that are touching the ground.
COFFEE PLANT LEAF SCORCH
The coffee shrub does not like being in direct sunlight or extremely dry and windy conditions. Scorch on the leaves is typically a sign of these harsher conditions, but it can be avoided by planting the bush where it will not be exposed to either.
Though scorched leaves may never green up again, providing enough water and moving the shrub to a location with partial or dappled sunlight should help. Remember that a little bit of burning is normal during especially hot summers.
PREVENT COFFEE PLANT PROBLEMS
Future leaf browning can be prevented by providing the plant with proper coffee arabica care and soil conditions. The University of California Cooperative Extension Service recommends a pH between 4.2 and 6.0 for optimal growth.
You should use fast-draining potting soil and a bright, sunny spot in front of an indoor window to care for your shrubs indoors. To prevent leaf spots from fungal infections, you can apply a diluted copper fungicide once per month when the plant is flowering.
How To Care For Coffee Plant?
To make your coffee plant happiest, grow it in bright light spots. As the plant reaches its full size, you can trim back the excess growth to give the rest of your coffee a denser and healthier look.
You will need to water the coffee often, between once a week and every other day. It should be watered less frequently than a standard houseplant.
A plant native to tropical regions, coffee thrives in high relative humidity. But if your home has too little moisture, the leaves of your growing coffee plant may turn brown edges or tips. Incorporate more humidity to keep new leaves healthy and green.
A minimum is to fertilize your coffee once or twice a year in the spring and summer, but you can do more as often as you want.
Some Other Related Questions
How often should you water a coffee plant?
Roughly water every week, and reduce watering in winter.
Water deeply each time and don’t let the soil dry out. To be honest, it’s difficult to judge when to water based on leaf color alone.
How do I save my coffee plant?
The soil should be kept moist, but any excess water should be removed from the roots after watering. The pot may also benefit from a humidifier or humidity tray to keep the coffee plant thriving.
How much light do coffee plants need?
Coffee plants enjoy bright, but indirect light. To achieve this lighting, they should be placed next to a window, although not directly in the window itself. The coffee plant also cannot tolerate temperatures below freezing and does well with warmer temperatures (below 65 F).
Coffee, a favorite drink worldwide, is made possible thanks to the Coffee arabica plant. Growing up to 15 feet tall, the evergreen shrub produces bright red berries that surround coffee beans. The leaves of this plant are typically green and shade their coffee beans from frost or scorched areas. If your coffee arabica plant has leaves turning brown, these are the three most common reasons that this happens.
I am Ralph Mason and I am a passionate coffee drinker. I worked as a barista for a few years and since 2012 I have been trying to convince as many people as possible of good coffee.
I started writing on the barista blog on RepublikCoffeeBar in 2018. It was a pure hobby site and I tested coffee products like coffee machines, beans, mug, and other accessories. After the first year, my blog is becoming a well-known coffee site with about 100 thousand visits per month.
In 2019 I decided to focus on RepublikCoffeeBar only. I became a full-time coffee blogger and was declared crazy by many.
