My Norfolk Island pine is not doing so well: the needles are turning brown and the branches are drooping. See photos below.

Why did this happen to my plant, and how can I cure it?

Is the pot draining well? I have had norfolks die from overwatering. –  Evil Elf Jun 7 '13 at 13:37
    
I recently made several holes, also removed try tray at bottom, so that water goes off, I water after every 3 to 4 days, climate is moist, only problem is that plant wasn't getting direct sun light. –  Kunal Bhatia Jun 9 '13 at 4:28

My (limited) understanding of Norfolk Pines is that they:

  • Don't like to be re-potted and will sometimes go into shock when this is done.
  • Like a moist environment and some folks will mist them weekly. It is my understanding that they are originally from a subtropical climate.
  • Can exhibit the curling up when being over-watered or under-watered. How often are you watering it?
  • Like to be near a window and get plenty of light each day. And do better if they can get some direct sunlight rather than indirect sunlight.

Are the branches drying out - it looks that way in the picture to me.

Did you recently re-pot it?

Are you perhaps over- or under-watering it it? We usually water our indoor plants once the top inch has dried and then water them until we see some water in the bottom tray.

What about fertilizer? There are indoor plant fertilizers and this plant might benefit from that if you aren't already giving it an occasional does of an appropriate fertilizer.

One thing about this tree that I read is that it really does best when it gets direct sunlight and enough moisture. The humidity level in most houses is going to be much lower than what the Norfolk Island Pine will want and so misting it often with a spray bottle will help. A humidifier would help too, though that is a bit more of an investment.

I'll follow your guidelines... 1) to keep plant in sun light 2) spray water on leaves 3) Not to re-pot 4) Not to overwater. –  Kunal Bhatia Jun 10 '13 at 12:54

From here the Norfolk Island Pine likes

The ideal indoor climate for this species is bright and cool, with daytime temperatures ranging from 60 to 70 degrees and slightly cooler at night.

My experiences with this plant is that the dry conditions (relative humidity less than 40%) that are so common inside our houses are not ideal for this plant. Under less than ideal conditions it will drop lower branches as fast as it grows new ones from the top.

A south exposure is too hot in most locales and bright northern light is better in the Western hemisphere.

Wikipedia notes that

It grows well in deep sand, as long as it receives reliable water when young. This, and its tolerance of salt and wind, makes it ideal for coastal situations. Additionally, it is necessary for the species to be grown in oceanic coastal areas because bodies of fresh water do not provide enough precipitation, moisture, consistent wind levels and no saline air which are all things the species requires.

I do not agree that these plants need saline air but suspect that a sandy soil with constant access to moisture would be more successful than the common peat based soil and regular waterings. A wicking system as described in the link would be a low maintenance alternative.
