tophat blueberry plants -- several questions
[I'm a new gardener, so please forgive these naive questions, and please talk slow when you answer.] :)
I just bought 2 dwarf tophat blueberry plants from Gardens Alive. They arrived today. I've read several other threads about these plants and I'm still really confused. Here are my questions.
Container type: Seems a 20" pot is ideal if I don't want to repot for at least a couple of years. True? Can I just buy standard type pots and use them as-is or do I need to do any drilling/lining/etc.? I assume I should mulch.
Cross-pollination: GA catalog says "No pollinator needed." Does this mean I do not need to buy other blueberry varieties? Would it be helpful for me to do it anyway? If so, what varieties do you recommend?
Timing: OK to put them in pots and place outside right now? Is winter too close?
Winter: OK to leave them out in pots over the winter? Is it critical to bury the containers for the winter? If so, when should I do it and when should I pull them back out?
Location: North side of house is pretty sunny but limited space; could put pots on front steps if they're not too big. West side of property is lined with hedges but gets lots of sun during the day. Rest of property has big trees and is pretty shady. Suggestions?
pH: How carefully do I need to check soil pH, and how often?
