I recently planted a Strawberry Guava shrub on the southern side of my house (full sun). I have been watering it almost daily since, otherwise the newest growth withers within a day or so. Right when I put it in it grew about 4-6" of new growth. Since then it stopped growing and one would think that it's focusing on root growth, but at the same time if it was growing roots then it wouldn't wither without 1 day of watering after 2 months. I fertilized it after 2 months with palm fertilizer per the man at the nursery. He said that I did not need to amend the soil, which I believe after researching the plant.

Any ideas?
