Pine 'needles' are often used for mulch. Around gardenias, they help retain moisture.
Pine cones? Shouldn't harm...may cause water retention initially, until they rot and
die...which would probably be quiet a while. I have a gardenia under a pine tree
and it's doing really well. Gardenia's like acid. So I'm not sure what (other than
partial shade) the pine tree does, but it does seem a most apros place for the gardenia.
