Question
I have an avocado sapling that is about two months old (approx. 12-14 inches) and that, until recently, was progressing quite well.  I have it in-doors on a south-facing window sill in well draining soil.  Over the last couple of days several of its initial leaves have shriveled and turned brown.  However, it has also sprouted new leaves which appear to be doing well.  Should I be at all concerned about the shriveling of the initial leaves?  Thank you much in advance.

Answer
Hi Matt,
Thanx for your question.  It's normal for leaves to age, shrivel up and fall off.  If your tree weren't replacing them with new leaves I might be concerned but I think your tree is just discarding old leaves.  Summertime is a great time to let your indoor plants like potted avocadoes have a summer vacation.  Put them outdoors in the shade for 10 days and then in full sun until just before the first frost is anticipated.  Your plant will be much healthier getting real sun and being out in the real elements.  Be sure to water every day.  Side dress the soil in the pot with some well-composted manure.  I hope this helps.
