It does not need a pollinator and is highly productive. It generally can grow to 20-30 ft on average but at maximum can reach up to 70ft. Mine is currently 8ft. I love being out in the garden and pruning so I won't let this guy get anymore than 15ft. No need to feed just the birds.
I only fertilize once a year with some tomato fertilizer which is lower in Nitrogen and higher in Potassium and Phosphate. I don't want it to grow too quickly but instead focus on fruit production. I also top it with Bone meal around the base.
So far it's been a very reliable producer and will continue to be one of my favorite trees every year. My son loves it too. He's only a 1yr old but has already chosen this tree as his favorite.
