Quick question on cross pollinating
If a tiny fruit forms on a tree that needs cross pollination, does that mean it was indeed properly pollinated? I had some plums last year that showed tiny fruit after the flowers fell off and wanted to know if that meant they were properly cross pollinated or if all flowers end up creating a tiny fruit? None of the fruits grew much larger as they all dropped.
Trying to figure out if I need o buy and plant cross pollinators or if there was another reason for zero plums off of two trees last year.
