How to Grow Herb Coffee: Step-by-Step Guide

If you’ve ever wondered how to grow your own herb coffee—without relying on traditional coffee trees—this guide covers everything from soil prep to harvest. Unlike arabica or robusta, herb coffee (also called ‘non-coffea coffee’) is a hardy alternative that can thrive under the right conditions, with proper attention to water, fertilizer, and pest control.

The best time to plant herb coffee is between April 15 and 25. Choose well-drained, sandy-loam soil, avoid high-fertilizer inputs, and never use chemical herbicides 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 risking frost damage to young plants.

You can grow herb coffee in a variety of locations: plains, gentle slopes, uncultivated land, or even around the base of young fruit or forest trees. Avoid planting near tall trees or in areas with poor air circulation. It’s adaptable to edges of properties, gaps between trees, or unused plots—but not heavily shaded or wind-blocked spots.

Growth Requirements and Plant Traits

Herb coffee thrives in warmth and tolerates drought but is sensitive to cold. Frost can kill young plants or defoliate mature ones, preventing seed development. It prefers deep, loose, well-drained sandy soils with good drainage, though it can grow in less ideal ground. The plant does not demand rich soil or heavy inputs.

Ideally, the soil should be sandy loam, rich, deep, and well-drained. While it can grow in marginal land, performance improves with better drainage and fertility. Excess water or cold snaps are the main stressors.

Starting Your Herb Coffee Crop

Seed selection is critical. Before planting, test seed viability: divide plump seeds into batches, soak 125–250g of each in 50°C water for 24 hours, rinse, then wrap in a damp cloth. After three days, select batches with over 85% germination rate for sowing.

Prepare the soil by applying 2000–2500kg of well-rotted manure and 25kg of calcium superphosphate per mu (about 0.067 hectares), then plow, harrow, and level the ground. Avoid making raised beds unless necessary—use 1.2–1.5m-wide flats if you do. Soak selected seeds in 50°C water for a day until swollen, then dry them lightly before sowing during the Qingming to Grain Rain period (mid-April), when temperatures are 15–20°C. Sow in rows 50–70cm apart, dig 5–6cm trenches, place seeds evenly, cover with 3cm of soil, and press lightly. Seedlings usually emerge in around 10 days. In dry northern areas, pre-water the soil—not post-sow—to prevent crusting.

Caring for Growing Plants

Once seedlings reach 3–6cm, thin weak or overcrowded ones. At 10–13cm, set plants 30cm apart to finalize spacing. Always loosen soil and remove weeds during thinning and setting. Herb coffee is drought-tolerant but benefits from occasional watering in dry spells. However, reduce irrigation while plants are ‘hardening off’ (during seedling establishment). Stop all watering by early September (White Dew), when fruits begin maturing.

Before plants reach full canopy (around 35cm tall), apply 20kg calcium superphosphate and 10–15kg ammonium sulfate along the rows. Hoe it into the soil and mound slightly to support plants and feed roots without promoting lodging.

Pests and Diseases

The most common disease is grey spot, caused by a fungus affecting leaves. Look for light brown patches that develop grey mould. Prevent it by spraying 500x diluted 65% zinc bacitracin or 800–1000x 50% thiram before or at first sign. Pests like aphids appear in late spring to early summer; treat with 200x diluted dimethoate spray.

Harvesting, Processing, and Storage

Herb coffee ripens around the Autumn Equinox (late September). Harvest when seed pods turn yellow-brown by cutting whole plants, drying them, then threshing seeds and cleaning debris. Store in a cool, dry, ventilated area away from moisture and rodents.

Frequently Asked Questions

What is herb coffee and how is it different from regular coffee?

Herb coffee refers to coffee-like plants that are not from the Coffea genus—often called ‘non-coffea coffee’. Unlike arabica or robusta, it’s a hardy alternative grown for seeds that may be used similarly, though it’s not true coffee. It tolerates poorer soils and harsher conditions but produces a different product.

When is the best time to plant herb coffee?

The optimal planting window is between April 15 and 25, when soil temperatures are warm enough for germination but not so high as to stress young plants or invite frost later.

What kind of soil is best for growing herb coffee?

Herb coffee grows best in deep, loose, well-drained sandy loam. It tolerates poor soil but performs best in fertile, aerated ground with good drainage. Avoid compacted or waterlogged soils.

Do I need to fertilize herb coffee?

No. Herb coffee does not require chemical fertilizers. If possible, use well-rotted manure. Avoid synthetic fertilizers and herbicides entirely, as they harm the plant and the crop.

How and when do you harvest herb coffee?

Harvest herb coffee around late September (Autumn Equinox), once the seed pods turn yellow-brown. Cut the whole plant, dry it, then remove and clean the seeds for storage or use.

What pests and diseases affect herb coffee?

The main disease is grey spot, a fungal leaf infection. Aphids are the most common pest. Control grey spot with zinc bacitracin or thiram sprays; manage aphids with diluted dimethoate.
