Notes for landscape architects and designers putting Thai Botanic material into a drawing set.
At design stage
Ask us before the schedule is fixed, not after. We can tell you what is genuinely available at the size you are drawing, which species will hold up in your destination climate, and where a substitution would serve the scheme better than the tree you had in mind.
Availability at large calliper is the constraint that most often forces a late redesign. It is worth checking early.
How we measure
Conventions vary between suppliers, and a schedule that assumes one convention and receives another causes arguments on site. Ours:
| Height | Measured from the top of the root ball to the highest growing point |
| Calliper | Trunk diameter measured 1 m above soil level |
| Root-ball diameter | Widest horizontal dimension of the wrapped ball |
| Root-ball depth | Top of ball to base, measured after wrapping |
| Clear stem | Root collar to the lowest permanent branch |
| Tolerance | Confirmed against your schedule at quotation, per species and size band |
Specifying from this catalogue
Each entry in the species catalogue carries mature height and spread, the calliper and root-ball sizes we supply, and site tolerance written with arid and coastal conditions in mind. Figures marked [to confirm] are being verified against current stock — ask and we will give you the real number for the size you need.
Botanical names follow currently accepted nomenclature. Where a species is widely known under a synonym, both are given.
Plant schedules
Send the schedule in whatever format you already work in — spreadsheet, PDF, or an extract from the drawing set. We return it marked up with what we can supply, at what size, and where a substitution is worth considering.
Ask and we will send the current species list as a single document you can attach to a drawing set.
Visiting the farm
Specifiers working at volume are welcome at the nursery in Suphanburi, about 185 km from Bangkok. Seeing the stock standing is the fastest way to settle a specification.
Design-stage questions are welcome and cost nothing. Get in touch.
