fruit trees- suckers and water sprouts. [View all]

so, i have this cherry tree. a purple cherry. it about 4 yrs old, and this thing just sends out suckers like it’s gonna die. it has a very scraggly habit anyway, sending out new shoots every which way. have yet to get cherries, and thinking it’s just a dud i shd take out.

i also have a pear that sends up water sprouts like crazy. partly cuz it got a too heavy crop too young and a lot of the branches got bent down. i had pros come and trim last yr, cuz things got away from me while i was sick for a long time. but there’s only so much they cd do at 1 time. can i trim these now, wait for the fruit to set, or just wait til winter?

any advice to get this stuff under control?
