The proof
Same house.
Same weeks.
Counted stem by stem.
We tracked five varieties in commercial production for a full year in Naivasha, counting, grading and weighing every day. On every one, ProTatu finished ahead of Natal Briar — the lead widening as the year went on. This is just one trial. We have done many over the last twenty years and the result is more than often the same: PRO Rootstocks outperform Natal Briar and give your farm a supercharge.





And it isn’t only these: across the wider trial, 39 of 45 varieties gave more stems on ProTatu than on Natal Briar — median +20.4%.
Every variety earns a rose-grade for the floor it has proven it can reach — ✿ beats Natal Briar, ✿✿ strong, ✿✿✿ exceptional. Look up your variety →
