How often should I water leaf propagations?

Prof. Charles Hartman, Ph.D.*Propagation of succulent leaves is determined by watering frequency. Overwatering causes rot, and underwatering leads to desiccation of developing roots. I water only when the top 1/2 inch of soil has dried completely. This happens about every three to five days. This continues to provide moisture without sogginess and protects the delicate meristematic cells at the base of the leaf.
Calloused Leaf Phase
- Method: Light misting using fine spray bottles
- Frequency: Every 5-7 days when soil surface turns pale
- Volume: 1-2 sprays per leaf avoiding the base directly
Root Formation Stage
- Method: Bottom watering soaking tray for 5 minutes
- Frequency: Every 3-4 days when roots appear white
- Volume: Enough to moisten entire soil depth
Pup Development Phase
- Method: Direct soil watering around base
- Frequency: Every 5 days when pups show color
- Volume: Quarter cup per plant avoiding foliage
Test soil moisture using the knuckle method. Stick your finger in up to the first knuckle and don't water unless it feels scorched. I also use moisture meters for accuracy. Don't have a set watering schedule, but water according to the soil's condition, as this changes with the climate and season.
Understand hydration signals from leaves. If the leaves are wrinkled, the plant is underwatered; if they are translucent, it is overwatered. Healthy propagations consistently remain plumply shaped with slight curling upwards of the leaf tips. I check the leaves daily and water them appropriately, not according to a calendar or schedule.
Adjust watering methods as roots develop. You start with misting and switch to bottom watering when you see white roots. This prevents putting shock on your delicate new growths. I soak mine for five minutes in shallow trays with water 1/2 inch deep.
Consider environmental factors such as humidity and temperature. A high humidity will require you to water less; however, high temperatures will increase evaporation rates. My propagation journal noted that summer conditions needed 40% more watering than winter conditions!
Avoid usual blunders by refraining from watering the foliage directly, and no watering at night. Water in the morning so it evaporates during the day. I have watering cans with long spouts, allowing me to water the soil without wetting the foliage.
