Khat cultivation:

Try to replicate the conditions of high altitude Ethiopia !
I have had great difficulty growing Khat from seed, however once you have a plant growing it is easy to take cuttings.
Catha edulis is adapted to a wide range of soil conditions (near Harar, where most of the Khat is grown, the soil is said to be neutral to slightly acidic despite being high in calcium and low in nitrogen) - it is suggested that water supply is more important than soil type, particularly in the early growing period.
Catha edulis does not tolerate poor drainage and will not grow well in wet soils.
It will grow in full sun, partial sun, or even shade.
In Ethiopia Khat is not grown from seed, but is vegetatively propagated from 12" suckers or branches near the ground level, and sometimes by cuttings taken from branches (although these do not root so readily).
Plants are set out when the rainy season begins.
The top parts will be cut back by frost but Khat plants will grow back from the roots - unless they are frozen too.

Catha edulis is adapted to a wide range of soil conditions, ranging from light, sandy to heavy black. Water supply, however, seems to be more important than soil type, particularly in the early growing period.
The entire area of Alemaya, Combolcha, Harar and the eastern extremity of the Chercher Highlands is hilly, and erosion is severe, so chat is grown on the hillsides, which are usually terraced, while lower lands are devoted to sorghum, corn, vegetables and grazing.
Granite is the prevailing parent material, along with limestone and sandstone. The soils are red or reddish-brown, neutral to slightly acidic, and high in calcium and low in nitrogen. A good response in plant growth is realised from fertiliser applications. Nitrogen applications increase the vegetative growth of chat, and thus increase the yield.
Chat can be grown in dry areas provided there is irrigation, but it does not tolerate poor drainage and does not do well in wet soils.
Sorghum, corn and sweet potatoes are generally intercropped with chat; this is possible as the chat trees are so spaced that they leave much area between plants. The preparation of the seed bed for intercropping is in a sense a cultivation of the chat field, so the chat benefits.

Germination guide for Catha edulis

These notes are a general guide, it is recommended to check specialist literature for some of the more unusual seeds in our lists.
Seed Germination Theory and Practice by Professor Norman C. Deno
Some knowledge about growing from seed is necessary to germinate even the easiest seeds. Most seeds require humidity to germinate, even desert plants like Welwitschia mirabilis require that their growing medium remains moist until germination.

Most seeds require oxygen to germinate, if buried too deep in their growing medium, or if the medium is too wet, the seeds may not get the oxygen they require.
Some seeds need to be in the light (surface sown) or in the dark (sown deep enough to receive little or no light) to germinate. A rule of thumb is to cover the seeds their own width deep in the growing medium, but some seeds prefer to be sown much deeper, and some fairly large seeds like to be surface sown (or higher).
Many seeds germinate best at certain temperatures, some will germinate at a comparatively wide range of temperatures, yet others need fluctuating temperatures.
Almost all seeds are waiting in a dormant state for some outside stimulus to break their dormancy, some just need sufficiently high ambiant humidity, others need scarification, vernalization or to be passed through the intestines of an animal.

Catha edulis seeds will usually germinate in 7 days, if conditions are favourable.
Normally germinates in the dark. Sow Catha edulis seeds about 5mm deep in a free draining, but water retentive seed sowing mix at about 35°C.

Soak in warm water for a day before sowing, I have had the best results at around 40C. Gibberellins are said to be helpful.
