Question
Hi,
In February or March this year I put some pomegranate seeds in some soil, and four of them came up. The smallest is now about 35 cm (1 ft) tall, while the biggest is about 75 cm (2 1/3 ft). I grow them indoor in Norway (63 degrees of north). When it has been really hot (25-30 degrees Celsius) and strong sunshine in the window, I've put them away from the window. I've watered them almost every day, and almost never let the soil get dry at all.
Now I see that some of the leaves are a bit ... what to say ... maybe curly. I wonder if that is because they get too much water (in the beginning they seemed to like much water). Or maybe they need really a lot and now get to little water? Or maybe I should give them fertilizer more often? Today I discovered that some of the lowest leaves are yellow and have came off. Are they entering winter mode already? It has been really much light in the summer because I'm living close to the area with midnight sun, but now it's getting darker. The temperature and day-time sunshine is still fine as it was earlier in the summer. Indoor temperature is between 20 nd 25 degrees Celsius.

Well, to sum up: My main question is: Why do the leaves get "curly", and what to do to prevent it?

I hope you will be able to answer from the information I've given you.

Sincerely, Gunnar H.

Hilsen Gunnar H.,
Thanx for your question.  The temperatures seem fine for your pomegranates.  I think you're watering them too much.  You need to allow the soil to dry out a bit and make sure the pots drain well so the roots do not sit in soggy soil.  Fertilize your plants with a balanced 12-12-12 fertilizer according to the directions on the container.  I definitely think you are watering too much.  I don't recall that pomegranates are daylight sensitive as far as growing goes but I could be wrong.  I live in the Midwestern U.S. where we have long days in the summer compared to the Southern U.S. and the tropics and I can pretty much grow whatever I want.  One thing Gunnar, put the pomegranates outdoors when you don't have anymore frost conditions and leave them outdoors for the summer unless you get frosty nights.  The pomegrates like to be outdoors and enjoy the sun.
Twenty-five to thirty Celsius may be hot to you but this tree grows in the Middle East and Southern Europe where summer temperatures often exceed 35 C.  It is a tree that grows well in Israel, Lebanon, Egypt and North Africa as well as the South of France, Southern Spain, Greece, Italy and in Florida, Texas, Arizona and California in the USA.  So, less water, more sun outdoors in the summer and I think the pomegranates will be fine.  I hope this helps.  I have a friend whose ancestors immigrated from Norway in the 1890s to North Dakota.  Her family still makes a dish called Kumla which I had never eaten until last year.  We have also discussed ludefisk but no one seems to want to try that!  Also they enjoy making lefsa.  Some of these dishes may not mean much to modern Norweigians nowadays.  I don't know.  We have some Swedish communities in my state mainly the Swedish community of Lindsborg, Kansas which the Swedish King visited in the 1970s.  I have been to this town before and it is very clean and well-kept and still maintains the Swedish heritage, et al.  I know the Norweigians established their independence from the Swedish throne 100 years ago but I was just mentioning the Swedish immigrants to my state as a reference point.  Some day, I hope to visit the countries of Scandinavia.  Anyway, I diverged from the main subject.  

I hope my answers to your horticultural questions were helpful.
