Duane,
Which copper product did you use, and how much does the label say to use per gallon?

Thanks Guanabanus,
It was BONIDE brand 0.5 to 2 fl ounces per gallon. My solution was very dilute (~12 ml per gallon). I was applying it weekly to closed buds.

4 weeks ago I began applying weekly copper to the new buds on this PPK.  We had several days of temps down to 35 degrees followed by heavy rain. In the last 2 weeks most of the buds that I sprayed have turned brown but the PPK has the leaf changes shown here and the dead flowers.  I thought most of the copper had been washed off by the rain which was heavy for Southern California. I see similar bud damage on most of the trees that I sprayed except  Sein ta Lone and a few others. The copper was pretty dilute - only 3ml of concentrate per quart.  I am in California, Zone 9b/10a.  Any thoughts?

Thanks.

No compost or fertilizer in planting hole.
Mulch is cleared from the crown.

I will cut the water way back and apply some Palm Gain: It meets the specs you posted.

Thanks Guanabanus.

Hello,

I'm new to the forum but have read the threads many times to learn more about mangoes.  I have been "obsessed" for about 2 years and have about 20 plants, mostly in pots.  I would like to grow enough mangoes to share with my colleagues and friends.  I live in Rancho Cucamonga, CA  -- Zone 10a.  Looking forward to learning and contributing.

Hi, I'm in Southern California and new to the forum.  I was seeking the forum's help with some leaf changes on a Fruit Punch mango that has been in the ground for about a month.  The mango is on a drip system and might have been over-watered.  The weather has been in the low 70s and night temps in the mid 40's.  The tree has full sun for about 7 hrs per day. I have posted some pix of the leaves and new growth.
Thanks for your help.
