Malus sieversii. I got a grafted malus sieversii that supposedly makes really nice fruit so i planted it recently. I made an effort to protect it really well since i get a lot of damage from deer. Malus sieversii was found to be the ancestor of all modern apples. Trees were found in kazakhstan that were estimated to be 4 to 5 hundred years old. Trees of 30 meters height! (98 feet) were also discovered. When the apple made its way to the modern world a lot of genetic diversity was lost in the process and nowadays malus sieversii is being used widely in apple breeding to reintroduce disease resistance and other useful traits into modern varieties.

 I am growing sesame for the first time this year. It's a beautiful and very useful plant. I never grew it before so i made lots of mistakes. I planted them into the ground while they were still very small and then i lost 15 out of 20 seedlings to slugs and snails in the polytunnel. This one is about to flower soon and the next one too. I have only 5 plants from 4 different varieties (one variety i have two plants left) whereas i planted 20 plants 4 each of 5 different varieties With a bit of luck i might get some seeds of all remaining plants i hope.

 Avocadoes. I am trying to grow avocadoes in my polytunnel and outdoors. I managed to obtain Del Rio avocado seeds and 5 seedlings are growing under plastic. They survived the winter but the smaller ones suffered more than the larger ones so i wonder if it's the seedlings size or if some are hardier.  This is the biggest and also the best looking Del Rio seedling after the winter. It had the least leaf damage. One of the two small seedlings that both suffered most damage. And the second small one. Then there is two medium sized ones  They both look pretty good so i am asking myself if the size determines hardiness or if hardiness determines size.                                In other words, has the largest of the 5 seedlings the least leaf damage because it's larger, (and then the other ones could be the same when they get bigger) or did its inherited frost resistance help it along all the w...

 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.
