Can anyone shed light on why 3 very healthy jostaberries have not flowered in the 3 years they've been in the ground? They are within 12 feet of each other, and also near a healthy group of productive gooseberries and a serviceberry tree that produce well. They are regularly watered, lightly fed and seem in great shape- Except for that part about not producing even a flower, much less some fruit. They were grown in my locale, supposedly for this climate (zone 5A). Any helpful hints?
