Sorbus domestica. One of my trees, a grafted "Sossenheimer Riese" true sevice tree,  is sick and has been for a while. I don't know what disease it is. It causes the branches and buds to dry off and die. It also leaves black, ugly marks on the bark. I cut off the top of the tree this winter and i put a heavy BRF mulch (bits of branches) around it and i am hoping that it will recover or at least continue to grow. It is very difficult for me to grow any sorbus trees here as they all seem to get diseases. An exception seems to be the service tree ( sorbus torminalis) that is growing fine for now. But rowan (sorbus aucuparia),


sorbus domestica and also different intergeneric sorbus hybrids (sorbomespilus, sorbaronia) all suffer and don't grow well for me.




I don't know what else to do to help the tree. I cut off the upper part and i gave it loads of mulch. I don't think cutting off all the affected parts will solve the problem, so for now i just wait and hope that it will heal itself.

 I weeded all my malus sieversii trees and i lost quite a few to what i believe was a combination of deer, rabbit and rodent attacks. I think i lost between one fourth and one third of the 426 plants i grew from seed. I discovered some visually very amazing and different ones in two of the six seed batches. I singled out several unique ones that i planted in my polytunnel to grow them properly. I didn't have the time to protect the 426 as i would have liked to. All trees of the 4 other batches have basically green leaves. Here is one example. This is a very nice green leaved one. And another green leaved one. Already these two are different in leaf colour and shape. But i selected them from the batches where all had green leaves in order to be sure to have genetic diversity. I kept 18 seedlings in the polytunnel that contain some of every batch. The following ones are very special and unique and display many variations of red and green and even other colours. One seedling with nice

 Avocado. My mexicola avocado is looking so bad now that i am starting to doubt whether it will grow back. It could always in theory sprout back up from the roots though and that's what i am kind of hoping for. If that happens i will probably cut everything off except the new shoot. I have a second smaller plant outside that looks in much better shape. It is a fantastic seedling so that might be why. To me, which might make some people laugh, it looks really good right now compared to the mexicola. fantastic seedling that up to now survived the winter quite well. Notice the green petioles of the brown leaves. This tree if no further catastrophe happens will surely grow again. And now here comes the mexicola: this is not looking good... It will be interesting to see if it grows back from anywhere above ground, from the roots or not at all.

Monkey puzzle

 Last year many monkey puzzle trees (araucaria araucana) around here made good nuts and for the first time i tried them. Raw they are ok, but not great like a raw sweet chestnut. Lightly roasted they are delicious. Roasted too much they turn hard and are less good. So i went and collected nuts under all the trees i could find and kept the biggest for sowing. I was surprised that they grow very easily if you don't let them dry out they germinate and grow quite well in poor soil. The seeds germinated very well and now i have quite a lot of young baby trees. One thing i love about them is that they don't need fencing. I heard that goats will eat them but my local wild life doesn't touch them. I will probably plant them all out amongst my larger ones. Lots of tasty nuts sometime in the future.
