Thoughts on Bella Gold

Here is the peacotum I have planted in full blossom. It’s from Raintree. The first peacotum I planted in 2013 died but they replaced it. Planted in 2014. It’s about 4 foot tall but I clipped off about a foot a couple weeks ago. I need to prune it some more (and should have done so before it woke up!), maybe take off those lower branches because I’d like to get it to a nice open center eventually. But I don’t want to kill the tree by being over-eager with the shears. Does anyone have advice on pruning and training? This is my weak area!

I have two Flavour Grenade pluots and a Santa Rosa plum as pollination partners. Right now the 1st Flavour Grenade you see staked in the background because I’m trying to spread the limbs. It’s in bloom now too but was about 5 days behind the Peacotum. The 2nd FG is to the right of the 1st in the image, the Santa Rosa is to the left. The 2nd FG was planted in 2015 and has no blooms yet, probably next year. The Santa Rosa has blooms but they haven’t opened yet so they’re not matching up with the Peacotum. The blooms on the Peacotum seem to be very long lasting - they’ve been open at least a week and are still going. I’ve also noticed bumblebees and honeybees flying between the peacotum and the FG and have done some hand pollinating. Even if it sets fruit I’m going to pick it off because I want the tree to focus on growing this year and get a better form established.
