"Citrus Blossom and Buds......."

When checking my 4 citrus trees this morning, I noticed several flower buds on my variegated lemon tree. I knew I had a blossom on my orange tree, but to see buds on the variegated lemon was truly surprising! The tree has not been doing well as of late, although it started regrowing leaves a few weeks ago after I sprayed it with a homemade "shower spray"......having used that last winter when I "think" it had spider mites. A few of the old leaves still have black spots, like mildew, but the rest of the plant is looking, and doing, very well.
