Blueberry bushes

me and my cousins usually pick them to make some money to buy stuff, last year they were to small and the plants were to sparse to make it profitable

So I planted a blueberry bush three months ago and it is still the same size as it was before. Can anyone explain to me why this is happening because I planted other plants and they grew just fine. By the way I live in San Diego California.

help

if so how

i was going to try to grow into a blueberry bush what do i need to do first i know i dont just bury the blueberry and pray

I would be interested in height and width.

I bought a couple of blueberry plants. They’re only about 10 inches high with 2 or 3 branches, with the leaves just budding. I’m going to nutture them as best I can, but how do I avoid those tiny, sour berries?

Someone told me they have to crosspollenate or something.
I mean do I have to plant 2 or 3 blueberry bushes together to get them to grow better and plant 2 or 3 plum trees together to make them grow better. I didn’t mean I wanted to plant the plum tree and the blueberry bush together.
