Was it knocked out of the pot, rcently root-pruned, or shocked by a sudden hard freeze? Those symptoms aren't likely caused by heavy rain.
Maybe upload a picture. Over how many days did it turn yellow. Pine needles usually turn slowly, did you spray it with anything? Perhaps the area you live in sprayed some kind of powerful insecticide it didn't like.... How are your other trees?
This may sound like a stupid question, but did you happen to water it while it was under the porch? Did it get any sun? ...
Rain water doesn't kill trees. Even acid rain won't kill a pine in one night. It's more likely that it was under watered all winter and just happened to turn yellow after the rain.
The only other solution is someone poured something on your pine like weed killer. Or it suffered from a real hard freeze. Can't think of any other reason your tree would turn yellow overnight....
I dont have one. Ill upload one in the morning. Im new to this, so do you have a pic of candles extending? Thanks guys for the help. Sorry for so little info.
