I've had a 3 foot tall Parfianka Pomegranate tree planted in the ground for several months. It gets about 7 hours of direct sunlight per day. It's been fertilized with compost, mycorrhizae enriched 10-10-10 fertilizer, and slow release fertilizer (In different months). I'm watering it deeply once a week. The leaves aren't browning, so I didn't think it needed that more water.
It has barely grown - just a few leaves here and there. I noticed that the color of the leaves are pale green, even white on the tips. Many of the leaves also have faint gray dots.
On the other hand, I have a Wonderful pomegranate of the same age growning nearby that has been doing stupendously. It's leaves are a deep forest green, it's creating many thick branches, and it's even flowering. The difference in care is that the Wonderful was grown in a pot in the beginning, whereas the Parfianka was immediately planted in the ground upon receiving it. The Wonderful is using Miracle-Gro soil, which is was more "soil-like" (dark black and mushy), while the Parfianka is using Kellogg soil (less composted, wood chippy).
This is a photo of the Wonderful. It's a little hard to compare because the lighting is different, but the Wonderful is definitely bushier, greener, and thicker.
