[Aroid-l] Monstera tenuis in cultivation.

From: abri1973 at wp.pl (Marek Argent) on 2008.07.04 at 18:41:57(18072) Hi, What to do with such climbers? I plant the young offset deep in the pot until the plant produces its own roots, then I tie it to a coconut fiber stake below every new leaf and keep it moist. The plant roots in it and each new leaf is larger than the previous one.

It is about five years ago that I found a well developed, adult species of Monstera tenuis in the Botanical Garden of Darmstadt (Germany). It didn?t have a name tag and nobody could tell. I got a stem cutting with two internodes and adult leaves. After I have cut the stem into two pieces (each nodium) I sterilized it and put it into a cup of fresh water. As soon root tips developed after two weeks, I put the cuttings into a cup filled with sterile, washed coarse river sand. There it took a while until new shoots showed. The result was: a stem of one millimeter diameter, very long internodes and tiny, round, juvenile leaves. The stems grew for several meters, but the leaves did not get any bigger. I cut the stems again and again and each new cutting produced the same type of new shoots. Over the years now, the oldest plants have a stem of 15 millimeter diameter and still the same type of round, juvenile leaves up to 20 cm diameter. I think it needs time and the right growing conditions to produce adult, split leaves as well as shorter internodes. I never had problems with rooting any cuttings,- like I hardly have problems propagating different Monsteras under "Central European greenhouse conditions". I am about to make a picture documentation of my different Monsteras (with a lot of ID- questions directed to the forum). I wish I had more time to do it. I?ll be back!
