I've read that MBVS can be difficult to root. I started 4 other varieties at the same time and all are exploding with roots, except MBvs. I'm using spagnum moss in plastic containers. The cuttings are leafing out without roots.
should I score the cuttings?
Does MBVS like cooler temps for rooting?
Cut the leaves?

Maybe I'm being impatient and just need to wait it out longer.

Thanks Matt

I recall mbvs taking a very long time to root, but were slow and steady. I was surprised that all cuttings survived. First year, they were slow to grow. In the second year I re-potted to a large pot and they really began to take off, catching up with other varieties quickly. I'd just be patient and expect a long rooting process (maybe several months). 

Wow- Several months... I wasn't expecting that. These cuttings will be small trees without roots. Should I cut the leaves off?

I personally had a tough time with that variety, and generally have a pretty good success rate. I had a couple that rooted but refused to put out leaves forever.  I had one that leafed out and died.  The 2 that survived I am thankful for and are growing vigorously with about 10 figs on them already. 

I'll keep my fingers crossed and give them time.

I have a few more cuttings - any rooting suggestion that might have a higher success rate for the MBVS?

Read this page then use the new alternative technique.  You can use any plastic container and you have to rinse the perlite dust off of the larger particles.  Use the coarsest perlite you can find.  If you have a hydroponics store near you they'll often carry ag grade #3 which is the perfect size.  If my cuttings don't root in 5 weeks I always change the media.

I rooted some this winter with 100% success rate, they actually went crazy with roots first and then took a while to produce leaves. I put the cuttings in moist coconut coir and it took about three weeks until I started to see roots. Then I up potted directly into 50% perlite, 50% potting soil. I invested in some supplemental light this winter (T8), that has made the largest difference in my success rates/ growth).

Sometimes it depends on the quality of the cuttings.

Hi Matt, Mine came from Herman 2 originally and I was able to root them 10 out of ten cuttings. I think thay are getting either too much light or too warm. I root mine indoors in the A/C in the dark till roots appear then move them to indirect light.
