Angraecum leonis growing in vase
About 1.5 months ago, I increased my watering of the Angcm leonis to twice daily in an attempt to simulate the monsoon season that this orchid experiences during the warm months. My hope was that extra watering would encourage some faster growth from this very slow orchid.
New root tips on Angraecum leonis
Within a couple weeks of the increased watering regime, the orchid activated new root growth, producing the branching seen in the picture above. These new root branches now measure between 1/4"-1/2" long after 1.5 months growth. I cannot conclude whether it was the extra water, or the additional exposure to Superthrive which directly caused this root growth.
I haven't notice any other changes in response to the twice daily watering. Now that the weather has cooled down (and because watering an orchid twice a day is a pain the neck) I scaled my watering regimen back to once daily.
Angraecum growth progress over 1 year
Although I complain about this orchid being the slow-poke of my collection, a comparison to my oldest photo of the plants does show a rather significant amount of root growth in the past year. In fact, most of the roots in the December picture are themselves newly grown (they are a light green, in contrast to the darker tone of the old roots). The truth of the matter is that the orchid arrived to me in poor health, and needs to regrow its root system before it can really start growing impressive leaves or buds.
