Timing for Marama Beans follows soil temperature and frost, not the calendar date. The Global vegetable planting calendar explains the method. To work out where it fits in your beds, sketch your plot in the free Garden Layout Planner.
What the research guides add
Marama is a wild desert legume that is barely domesticated, and the review below explains the drought strategy that decides where it could be grown.
- A wild perennial legume native to the Kalahari Desert in Southern Africa, growing mostly in sandy soils. (Frontiers in Plant Science)
- Because it grows in sandy soil, water can remain in the root zone for months after rain and a taproot reaches it. It also forms a true tuber that acts as both a starch reservoir and a water reservoir. (Frontiers in Plant Science)
- Older tubers weighing more than 200 kg can contain 90% water by weight, and the bean very likely survives drought by drawing on this stored water. (Frontiers in Plant Science)
- The seed is high in protein and the tuberous root high in carbohydrate, making the bean an important local food. (Frontiers in Plant Science)

Frequently Asked Questions
What soil pH do marama beans need?
A pH of about 5.5–7. That span reflects genuine variation between the authorities we cite rather than a single agreed figure — the References section lists each source's exact range.

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against international horticultural research and extension sources. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
