So, I actually just bought myself an A. Crassna tree! Seems they are finally being made available to the public. I'd love some tips on how to grow? This is purely for the love of growing unusual and rare plants. Not for any real desire of making my own oud (although that would be very cool). I live in sub-tropical Queensland Australia. Any ideas on what would be the best conditions for the tree to grow?
Agarwood Tree (Aquilaria crassna) is a prized medicinal and aromatic tree known by many names, including Eaglewood, Aloeswood, Gaharu, Oud, Agar Tree, Ca...

Nice going! This is one of the few threads mentioning growing agarwood as a hobbyist (not a plantation), and it just so happens I have 3 Aquilaria crassna specimens growing indoors under lights (I live in Canada, so year-round outdoor cultivation is not possible). I purchased 50+ fresh seeds almost 2 years ago, but they are so short-lived that after 2 weeks of transit (plus presumably a short period of post-harvest storage by the supplier) only 3 seeds germinated. I still consider myself fortunate to have them, and I plan to order more seeds this coming season.
As for soil and growing tips, this comes to you 6 months late but here's what I've learned:
-SOIL - Prefers moist but well-draining soil that is nutrient-rich (e.g. compost); they can grow in moderate levels of heavy clay and nutritionally-poor soils, but good drainage is best;
-LIGHT - Seedlings require shade until well-established; after that, established plants/trees can be grown in full sun or semi-shade;
-HUMIDITY - Plants prefer high humidity, if available (personal note: mine are grown exclusively indoors, and appear to tolerate typical indoor levels of 30-40% RH.)
-WATER - Plants prefer consistent rainfall throughout the year, or regular watering (especially younger saplings);
-PRUNING - Light pruning is recommended, to promote a strong trunk and branches as well as good overall tree form;
-FEEDING - Organic fertilizers are preferred, with good N levels for younger plants then transitioning to a more balanced organic fertilizer for older trees so as not to over-apply N while under-supplying other macro-/micro-nutrients that are important to root and wood development.
I recently had to defoliate my indoor plants and soap-spray them for spider mites, then I'll do a pruning (and try to root some cuttings??) and let them leaf out again. Then I'll post a new thread to show them here, and later some seed/seedling pics, in case others are interested in the idea of growing agarwood as a houseplant. I am also growing a range of other incense-relevant potted plants - including frankincense, myrrh, several copal species including palo santo, dragon's blood, atlas pistachio, gum arabic, and sandalwood. It's a fun hobby, and I plan to try selling live plants starting this year (domestic sales only).
Anyway, good luck with your crassna!
