How to Grow Herb Coffee: Planting to Harvest Guide

If you're trying to grow herb coffee—not the commercial arabica or robusta you brew, but the herbal or substitute variety—knowing the right steps makes all the difference. This isn't about producing roasted beans for espresso, but cultivating a hardy, non-demanding plant with its own unique care needs. Here's exactly how to do it, based on field-tested steps from actual cultivation guides.

The best time to plant herb coffee is between April 15th and 25th. It thrives in well-drained, sandy loam soil, doesn’t need heavy fertilization, and should never be exposed to chemical pesticides or synthetic fertilizers.

When and Where to Plant Herb Coffee

Herb coffee should be planted during a specific window: April 15 to 25. This timing ensures the soil temperature is warm enough for germination without being too hot early on. As for location, it’s fairly flexible—you can grow it in plains, on slopes, in wasteland, around your house, or even between young fruit tree seedlings. Just avoid planting it under tall trees or in areas with poor air circulation.

Soil, Water, and Fertilizer Needs

Herb coffee doesn’t like excessive water or strong fertilizers. If you have access to farmyard manure, that’s ideal. During its growth, watering once or twice during drought is enough—overwatering is not recommended. Importantly, never use chemical fertilizers or herbicides. The plant prefers soil that drains well, with deep, loose, and fertile sandy loam being optimal, although it can tolerate more marginal land.

Seed Selection and Germination Testing

Before sowing, test seed viability. Take plump seeds, divide them into batches, label them, and soak 125–250 grams of each batch in water around 50°C for 24 hours. Drain, rinse with clean water, then cover with a damp cloth. After three days, check for sprouting—only use seeds with an 85% or higher germination rate.

Planting Process Step by Step

Start by preparing the soil: apply 2000–2500 kg of farmyard manure and 25 kg of calcium superphosphate per acre, spread evenly, then plow, harrow, and level the ground. Don’t bother making raised beds unless you want to—they can be 1.2–1.5 metres wide if you do.

For the seeds, soak the selected ones in 50°C water for a full day until swollen, then dry the surface. Plant them during the Qingming to Grain Rain period (mid-April), when temperatures are between 15–20°C. Avoid early planting (soil too cold) or late planting (seeds won’t mature properly). Use the row planting method: space rows 50–70 cm apart, dig trenches 5–6 cm deep, distribute seeds evenly, cover with 3 cm of soil, press lightly, and expect sprouts in around 10 days. In dry northern areas, water before sowing—not after—to prevent surface crusting.

Field Management

When the seedlings reach 3–6 cm, thin them by removing weak or overcrowded ones. At 10–13 cm, set the final spacing to around 30 cm per plant. Do light weeding and soil loosening at the same time. The plant is drought-tolerant but benefits from modest watering in dry spells. However, reduce watering during the ‘dwarfing’ phase at final spacing. Stop all watering by White Dew (early September), when fruits near maturity.

Before plants grow too leafy (around 35 cm tall), apply a mix of 20 kg calcium superphosphate and 10–15 kg ammonium sulfate between rows. Hoe it into the soil and mound earth around stems to support the plants and prevent lodging.

Pest and Disease Control

The most common disease is grey spot, caused by a fungus attacking the leaves. Early signs are light brown spots that develop grey mold. Treat with 500x diluted 65% zinc bacitracin or 800–1000x diluted 50% thiram before or at the first sign. Pests like aphids appear in late spring to early summer; control them with a 200x diluted dimethoate spray.

Harvesting, Processing, and Storage

Herb coffee is ready around the Autumn Equinox (late September), when pods turn yellow-brown. Cut down the whole plant, dry it, remove the seeds, clean off debris, and you’ve got your herbal coffee ‘beans’—often used as medicinal material. Store in a cool, ventilated, dry place, away from moisture and rodents.

Frequently Asked Questions

What month is best for planting herb coffee?

The ideal planting window is between April 15 and 25, when soil temperatures are warm enough to support germination without being excessively hot early in the season.

What kind of soil does herb coffee prefer?

Herb coffee grows best in well-drained, deep, loose, and fertile sandy loam soil. It can tolerate poorer land but does not perform well in compacted or waterlogged soils.

How often should I water herb coffee plants?

Water sparingly—once or twice during dry periods is sufficient. The plant is drought-resistant and should never be overwatered, especially not right after sowing in dry regions.

Can I use chemical fertilizers or pesticides on herb coffee?

No. Herb coffee should never be treated with chemical fertilizers or any kind of herbicide or pesticide. Use organic options like farmyard manure if fertilizing is needed.

When is herb coffee ready to harvest?

Herb coffee typically matures around the Autumn Equinox (late September). You’ll know it’s ready when the seed pods have turned yellow-brown.

How should I store harvested herb coffee?

Store the cleaned seeds in a cool, dry, and ventilated area, protected from moisture and rodents to maintain quality and prevent spoilage.
