Because the plant architecture and resistance profile have changed, the growing instructions have been updated. Follow this new protocol for maximum yield.
Without specific details on the medium or exact composition of "Petit Tomato," one can still speculate on its potential artistic merits:
The updated variety has higher drought tolerance due to its nematode resistance. Allow the top 1 inch of soil to dry completely before watering. Overwatering is the #1 killer of the 2024 version.
For a few years (2022–2024), the Petit Tomato became notoriously hard to find. Production slowed due to supply chain issues with the Japanese steel laminates and a shortage of skilled finishers at the Takefu Knife Village.
