My three dwarf pomegranate trees have been growing in some small pots for a couple of years, and I felt they needed larger pots to flourish. Pomegranates do well in dry conditions, so I chose terra-cotta pots that should help prevent waterlogged soil.
To fill in the extra space in the larger pots, I used potting soil that I purchased at a home center. It contains fertilizer that is supposed to feed the plants for a few months. I added some sand to the soil, again to help prevent it from becoming waterlogged. I used pool filter sand because it is clean and contains uniform, small grains.
I also used a terra-cotta pot and added sand to the soil when I re-potted the jade plant last year, and I think it’s growing better now.
I put landscape fabric at the bottom of the pots to keep the soil from running out the drainage hole.
Next, I added enough soil/sand mix to the new pot to make up the difference in height between it and the old pot. I poked a soil knife around the inside edge of the old pots to loosen the root balls so I could remove the trees more easily.
Pomegranates are deciduous, so the trees have lost their leaves. Either that, or I killed them either by leaving them out in the cold too long or by letting them dry out. They should leaf out again by summer.
I used my fingers to loosen any roots that had grown around the edge of the pot and become matted, just like I do when I transplant vegetables. Then, I placed the tree in its new pot.
I added soil/sand mix to the pot to fill in the gap between the pot and the root ball. I pushed my fingers into the new soil to remove air pockets.
I watered the plants in their new pots to help settle the soil. It took about 1.5 pints (0.7 l) in each pot. As I actually used about two pints, I had to pour off the excess from the stainless steel steam-table pans that I was working in.
With the gnarled tree trunk and the moss growing around the base, the tree at the rear looks like it could be a bonsai. I think these dwarf pomegranate trees would be good subjects for bonsai.
I started these dwarf pomegranate trees from seeds a few years ago. I planted two seeds in each of the pots in a plastic “six-pack,” a smaller version of the one I use to start eggplant and peppers. The seeds required cold treatment before they would germinate, so after I planted them, I kept the six-pack in the refrigerator (in a plastic bag so they wouldn’t dry out) for six or eight weeks. Only three seeds germinated out of the twelve that I planted; of course, two were in the same pot so I had to separate them when I first re-potted them.
The dwarf pomegranate trees produce a lot of flowers in the summer and even some tiny fruit, which are edible but very sour.
