I have a small Crocston grapefruit grafted onto FD. The new growth started wilting last week and I noticed red spidermite infestation. I sprayed it and all my yearling trees that have been growing inside house over winter with paraffin oil solution per label for growing citrus. Mites are gone. Tree wilting in window yesterday so I planted outside and watered well. Still wilted and some yellowing stippling leaves. Shouldn't it perk up after watering? I'd place pic but don't know how. What do I do to save tree?[/img/Users/charlesfox/Pictures/iPhoto Library/Modified/2013/Apr 8, 2013/IMG_0970.JPG

Young tender new flush growth transpire water faster than mature foliage. Therefore, will wilt quicker than mature foliage. However, it should quickly recover when watered. If it continues to wilt you need to check the root system. I would not have planted it outside. It would have been better to gradually climatize the tree slowly, or even let the tree get a little growth before placing it outside. - Millet

No new growth yet on baby crocston, but still perky. Spring is a month behind as y'all know, and I had low of 36 degrees F last Friday and lower 40's the past 2 nights. Highs in 60's. my Citrus need heat!

Last week the temperature dropped to about 40 degrees officially, but there may have been a light frost. The following day there was severe wilting on all of the most tender growth. It was so bad I thought the spring flush would die. This included Poncirus. One plant was put in water in an attempt to revive it, but it stayed completely limp.
Some of the plants were brought inside and covered with plastic in an attempt to rehydrate them.
