🌿From Coffee Tree to Morning Cup 🍵

Sunshine: So coffee really can be grown at home?
Smokey: With proper care, your morning cup can begin on your own coffee tree.
Sunshine: Excellent. I am removing coffee from my Sunshine Special subscription. Donuts only.
Smokey: Please wait until the tree actually produces coffee.

Most people meet coffee as a bag of roasted beans. The plant behind it, Coffea arabica, is an evergreen shrub with dark shiny leaves, white flowers, and red fruit, and it grows well in a container.

Coffee is a Fruit Tree

What we call a coffee bean is a seed. Each seed sits inside a small fruit, commonly called a coffee cherry, with a layer of flesh around it. The fruit starts green and passes through yellow or orange-red before reaching full ripeness in deep red, depending on variety and stage. The flesh around the seeds is edible, though the seeds are the part normally processed into coffee.

Why Coffee Does Well In a Pot

Coffee prefers bright filtered light or partial shade. Harsh, exposed afternoon sun scorches the leaves and bleaches their color. That preference is what makes it practical indoors. A bright window, a shaded patio, a greenhouse bench, or a warm-climate spot under high canopy all work. It stays a manageable evergreen shrub or small tree in a container.

The Flowers

Coffee flowers are small, white, and produced in tight clusters along the branches rather than as single showy blooms. Their scent is often compared to gardenia or jasmine. Coffee and gardenia belong to the same family, Rubiaceae.

Flowering does not last long. A plant may open most of its buds within a day or two, and for that short stretch the whole branch is lined in white and the room smells like a gardenia hedge.

From Flower to Fruit

Once the flowers finish, small green cherries set along the same branches. They take months to size up and color. A mature plant often carries several stages at once, so you can find open flowers, hard green fruit, and ripe red cherries on the same branch. Flowering time depends on the plant's age, size, and growing conditions, so patience is part of growing coffee.

Practical Care

• Light: Bright filtered light or partial shade. Indoors, a plant will survive in modest light, but flowering and fruiting need more. An east or lightly shaded south window, or a supplemental grow light, is usually what it takes to get fruit.
• Water: Water regularly and consistently. Coffee is not a plant you can forget about. Let the top inch of soil dry out, then water thoroughly until excess water drains from the bottom of the pot. Never let the plant sit in soggy soil, as constantly wet roots can quickly lead to root rot. During the cooler winter months, reduce watering significantly. Coffee plants dislike the combination of cold and wet conditions and often enter a semi-dormant state in winter, when their metabolism slows and they require much less water.
• Soil and container: Well drained potting mix with some organic matter, in a pot with real drainage holes and no saucer full of standing water. We recommend Abundance - TopTropicals professional soilless potting mix with perfect drainage characteristics.
• Hardiness: USDA Zone 10-11. In colder climate grow in pot
• Temperature: Warm, and protected from cold. Coffee is not frost hardy, so in a marginal climate bring it in ahead of the first cold night when temperature drops below 40F
• Humidity: Moderate. Indoor winter air with the heat running is dry enough to brown leaf edges, and grouping plants or running a humidifier nearby helps.
• Feeding: A balanced fertilizer during active growth in the warm months, easing off in winter when growth slows. We put a scoop of GreenMagic controlled release fertilizer every 6 months and liquid SunshineRobusta that is safe to apply with every watering, year around. Coffee plants respond very well to fertilizers.

• Pruning and repotting: Prune lightly to keep the plant compact and encourage branching, since fruit forms on branches. Move up a pot size as roots fill the container.

From Cherry to Cup

Yes, you can make coffee from your own tree. The process is not complicated, but each step takes time, and most of it is waiting.

• Pick fully ripe red cherries. Underripe fruit makes poor coffee, and ripeness on a single plant is uneven, so expect to harvest in several passes over a few weeks.
• Remove the fruit pulp. A small batch can be squeezed or rubbed off by hand. Underneath is a seed still wrapped in a slippery coating.
• Soak the seeds in water for 12 to 24 hours to loosen the slippery coating.
• Wash the seeds until they feel clean rather than slick.
• Dry them thoroughly, spread in a single layer, until they are hard all the way through.
• Remove the parchment layer, a thin papery husk around each seed. At this scale, rubbing the dry seeds between your hands and blowing away the loose husk works. Easy trick: give the dried beans a quick 1-2 second pulse in a coffee grinder - just enough to crack the parchment loose, not grind the beans. Then simply separate and discard the loosened husks.
• Roast the green beans. A heavy skillet over medium heat or a hot air popcorn popper both work. Keep the beans moving and watch the color.
• Cool them quickly and let them rest a day before grinding.
• Grind and brew as usual.

Home processing is small scale and imperfect. Batches vary, and the results are inconsistent by nature. The pleasure is in growing, harvesting, processing, and tasting coffee from your own tree. It also makes for good company. Pouring someone a cup and telling them it came off a plant in your living room tends to get more attention than anything else you could serve.

How Much Coffee Will One Tree Make?

A home-grown tree usually provides a small personal harvest rather than a household supply. Yield depends on the size and age of the plant, growing conditions, how well the flowers set, and how many cherries actually ripen.

Think of a home coffee tree as an ornamental fruit plant that also produces real coffee.

As a Gift

Coffee works well as a gift for coffee drinkers and plant lovers, since the plant connects to something they already drink every morning. Shiny leaves, fragrant flowers, and colorful fruit come with it.
