Curious...what do you do if you should over-fert your plants and they curl under. Is there a way to save them?

i've heard you can flush the plants ... this is puttin a sh*t load of water in them, letting it drain, puttin water in, draining, and so on and so on for a long time. this will eventually get rid of the ferts, dont know how healthy this is to plants, i've never had to do it, cuase i sparingly fertlize mine...maybe 2-3 times a month they get a good big of pecan special fertilizer 25-5-10

Just remember, combinations can cause the symptoms to appear as a completely different problem.

Paying attention to your plant is still the best way to know what needs to be done.

Always allow 3-5 days for the effects of any change you make to become apparent. The damaged leaves usually don't recover, depending on severity of damage. Watch new growth.

Smiles,
