It may sound like I repeated myself.
Vandalay cracked so badly every year. A few that I got tasted similar to Black Gold, some sweetness, somewhat soft texture. I could not tell the difference between the two re. taste and texture. Removed Vandalay last year. No regret.
Biggest issues with cherries for me are cracking and rotting. Can’t prevent cracking (not willing to cover the trees with shade cloth when it rains) but Indar stops rotting.
My trees are on Gisela 5. A dwarf rootstock for cherry is a relative term. A cherry tree can grow 30-40 ft tall. 15 ft cherry tree can be considered dwarf. I has kept my BG at 6 ft tall in an umbrella shape.
I’ve read about many cherry pruning styles including KGB. You want to put 3-4 trees in a 12 ft long bed. That is a tall order, in my opinion. Even a KGB style needs at least 4-6 wide space. For 12 ft bed, two trees would be just right.
Cherry needs to have air circulation. Cramping them together could make rotting worse.
Heard that Lapins tastes good. Don’t know about Tehravinee or Hartland.
