Title: tangerine tree problems
Post by: TheFlyingFarmer on September 04, 2020, 10:14:54 AM
good day everyone, whos ready for labor day weekend?

while outside yesterday i noticed my tangerine tree had dropped all of its buds and the ends of some new growth were turning black. i had recently been dealing with asian psylids and finally seem to have a handle on them.

anyone have any ideas? my persian lime tree also had them but seems to be doing fine since the treatment.

thanks for any input

I'm not sure about the dried ends of the current new growth.   It could be under watering, as new tender leaf growth requires more irrigation than the mature foliage, due to the higher levels of transpiration (losing water) then mature leaves.  The curling and deformation of the larger mature leaves happened way back when they were just forming.  It was caused by insects such as thrips and others feeding of the new leaves. Tender new growth is dessert to insets.

been pretty hot down here in south florida, but ive been giving it about 2 gallons of water every 2 to 3 days, the soil about 2 inches deep is always moist.
