What I learned this winter
As usual I push the limits when growing plants. As my plant collection gets out of control, I'm constantly experimenting. (That way some die off lol)
1. H. dasyantha grows outside just fine down to freezing. It even continued to grow through the winter.
2. Both of my speckled leaves publicalyx grow outside just fine down to freezing. They slowed down the growth during the coldest part of the winter, but picked right back up when it warmed up.
3. My plain green leaf publicalys hated the cold. Had to bring it in and put it in ICU. Has since recovered.
4. Diversifolia, bella, polyneura, fungii, DS-70 and obovata did wonderfully through their second winter outside down to freezing.
5. In experimenting through the winter with rooting cuttings. Rooting in a Turface/Perlite mix, about 60% of the cuttings rooted and have started to grow. Also compared against rooting in S/H. About 90% rooting rate. (BTW, when using S/H to root plants that do not like to remain wet, when rooted I just poke holes in the bottom of the pot, converting it away from S/H without disturbing the plant)
6. I tried a mounting experiment on some plants. Serpens, calycina, diversifolia, obovata and probably a couple more I'm not thinking of. I used a cedar shingle, lined with spag, and tied down with fishing line. All have rooted and started growth. The serpens even is budding up.
7. My tap water absolutely does not have enough Ca in it I think. Once I started supplementing with Ca, yellow leaf drop stopped.
8. sp. Tanna Island doesn't know how to stop growing. The main plant grew even when I forgot it and didn't water it for a month. I left some rooted cuttings outside down to freezing, they grew. I have thrown every possible obstacle at this thing and it is still growing out of control. Now if I could just figure out how to bloom it.
I wonder what I'll think up next winter :)
