Do I assume correctly that if I use the grape leaves from my orlah grapevine, they have to be ma'asered?

I assume that grape leaves from my vine that is in its second year of orlah are allowed to be used.
Am I correct?

 I'm a yeshiva bachur and live with my parents. My parents have a lemon tree growing in their yard, from which they pick lemons. Can I subscribe as a member of Beit Ha'otzar and tithe the fruit without my parent's knowledge?

Whoever sees especially beautiful creations recites the blessing shekacha lo ba'olamo; "Who has such things in His world."
Whoever goes out to fields or gardens in the days of Nissan and sees trees blossoming and budding recites birkat ha'ilanot, the blessing for the trees: "Blessed … who has withheld nothing from His world, and has created in it beautiful creatures and trees for human beings to enjoy.'"  What is the difference between both blessings?

Can one say birkat ha’ilanot on trees grafted in a forbidden fashion?

I have blueberries growing in a planter in my garden. Last year, I was told I need to count orlah years for it, which seems to make it a tree. If it has flowers, can I count it as one of the trees for birkat ha'ilanot?

Can we say birkat ha'ilanot on a tree with buds that resemble white balls, whose petals have not opened yet, or is it necessary to see the petals of the flowers? We have an orange tree in this state now.

I was wondering what the halachic implications of companion gardening and permaculture are. 
Is there a way to plant a field this way without violating kilayim?

There are people who prepare liqueur from the small fruits that grow on myrtle bushes (hadas) during this season of the year (hereinafter: "myrtle berries"). Is it necessary to separate terumot and ma'aserot from them?
