While scarlet sage is most commonly propagated through stem cuttings or seeds, attempting leaf propagation can be an interesting experiment. Here’s a unique approach, blending typical methods with a twist:
The “Humidity Dome Leaf Bed” Method:
-
Selection
Choose healthy, mature leaves. Avoid very young or damaged ones. Select leaves with a portion of the petiole (the leaf stem) still attached. This is crucial.
-
Preparation
Sterilize your tools (scissors or a sharp knife) to prevent infection. Prepare a well-draining potting mix. A blend of perlite and peat moss or coco coir is ideal. Lightly moisten the potting mix.
-
The Unique Step: The “Leaf Bed”
Instead of individually planting each leaf, create a shallow “bed” of the moistened potting mix in a wide, shallow container. Lay the leaves flat on this bed, with the petiole slightly pressed into the surface. Do not bury the entire leaf. This “bed” style, increases the surface area exposed to humidity, and helps to maintain consistent moisture.
-
Humidity Dome
This is vital. Cover the container with a clear plastic dome, bag, or even a cut-off plastic bottle to create a humidity dome. This high humidity environment encourages root development.
-
Light and Care
Avoid direct sunlight, which can overheat the leaves. Regularly check the moisture levels. The potting mix should remain consistently moist, but not waterlogged. Ventilate the dome periodically to prevent mold growth.
-
Rooting and Transplanting
Gently check for root growth by carefully lifting a leaf. Once the roots have formed, carefully transplant the new plants into the individual pots.
Why this is somewhat unique?
-
“Leaf Bed” Approach
Traditional leaf propagation often involves individual planting. This “bed” technique maximizes humidity around multiple leaves simultaneously. It also reduces the amount of individual disturbances of the very fragile new root systems, that would occur from individual plantings.
-
Emphasis on High Humidity
Scarlet sage, while relatively hardy, benefits significantly from high humidity during leaf propagation.
Important Considerations
Leaf propagation of scarlet sage can be less reliable than stem cuttings. Success rates may vary. It is very important to maintain high humidity levels.
