Lemon tree very crispy and lemon flower is dead,
Lemon tree, there's no saving, so I'll dig it up instead.
Global Cooling managed to get my Eureaka Lemon tree. Fortunately it was less than a year old (and I save my tree receipts). Lowes gave me my money back, but had no citrus in stock yet, Home Depot did though.
Ended up buying a Meyer Lemon. Now the Meyer lemon is not a true lemon, rather it is a rather slutty citrus that climbed in bed with a mandarin sometime back in history. Still they are very popular, though a touch sweater than a true lemon.
