I heard you need another Blueberry plant to make them come back next year. How do I overwinter them?
It depends on your cultivar. Many varieties don't need a second plant for pollination but you will have more fruit if you do have more than one blueberry bush.
Their coming back depends on the hardiness zone you live in and what the hardiness zone is for your cultivar. For example, if you live in hardiness zone 8 (you do) and buy a blueberry bush rated for zones 4-7, it may not come back. The USDA hardiness zones help determine what temperature a plant will thrive on based on average annual minimum winter temperature.
Zone 8 is tricky for blueberries because they need a certain number of chill hours during winter to produce fruit the next summer. Be sure the blueberry bushes you buy are rated for zone 8. They also need very acidic soil.

I already cut away dry dead tips but wonder whether I should be doing something else. I repotted the bushes 2 years ago and each spring rake away the soil at the top and replace it. Many thanks.
Yes, you prune out two of the oldest canes each winter, as well as any dead wood and nonproductive wood. Here is a good video produced by the University of Maine.
I am really struggling with the proper way to trim my blueberry bushes. I have googled and used YouTube but still seem to limit my production each season.
One of your main goals should be to eliminate any branches/stems that are criss-crossing, opening up the middle of the bush so light can filter through it. Also, remove the two oldest canes each spring.

Hi there, 2 yr ago I opened up a new High bush blueberry area and it was doing well. Last year we put some mums in between the blueberry bushes and they wound up getting a bit beefy. They are all at least 12" apart. I'm wondering if these will bother the blueberry bushes development at all? Thanks, in advance,
Blueberry bushes will not tolerate most fertilizers. As long as you DO NOT feed with any nitrates and as long as what you feed them contains ammonium SULFATE and NOT ammonium NITRATE then they should be fine. Otherwise, Blueberries are sensitive to nitrates and will not do well when it is concentrated in the soil.

I've been told by the local nursery I can use coffee grounds to add nutrients and acid to the soil around my blueberry bushes to promote berry growth. I have a bag of unused (not brewed) coffee grounds. Should I dilute the grounds in water and strain the grounds out first or can I put the fresh grounds directly on the soil around my bushes? I wasn't sure if the fresh grounds would be too strong for the bushes and I didn't want to shock them and potentially harm them. Thank you
Fresh coffee grounds are better if you want the acidic benefit. Most people use a fertilizer recommended for azaleas and rhododendrons.
I have a very young blueberry Bush that was only planted a year ago. It survived all winter and a few weeks ago seemed to be full of young life with tiny new buds developing. Now it looks like it's dying. Can I save it?
Check your care with these care tips. Blueberries need very acidic soil and well-draining. Without those, it will suffer.
Fertilizing Blueberry bushes? How often and can you use 10 - 10 - 10 fertilizer
It would be best to use a fertilizer for azaleas and rhododendrons as blueberries are acid loving plants.
