Indoor pine trees aren't just for Christmas any more. Many people enjoy the look and the aroma of a living indoor pine tree all year round. The Norfolk pine makes an excellent choice for an indoor tree as it grows well in containers and its needles do not shed readily. Keeping a Norfolk pine healthy indoors involves the maintaining the proper balance between sunlight, water, humidity and fertilizer. Norfolk pines can be grown from seeds, or small container pines can be purchased.
Collect Norfolk pine seeds if you wish to grow your own tree. Gardening Know How.com recommends that you place the seeds in a bowl of water; keep the seeds that float and discard the others. Keep the seeds in a sealed plastic bag in the refrigerator vegetable drawer until late winter or early spring.
Fill growing pots with potting soil and place one pine seed in each pot. Press the seed into the soil with the pointed end down and the rounded end just covered with soil. Water lightly, keeping the potting mix damp but not soggy.
Place the growing pot in a sunny window where it receives plenty of direct sunlight each day. Keep it at approximately 70 F during the day, and 60 to 65 degrees at night. Be patient. The seeds should sprout in two to four months, according to AllExperts.com.
Choose a sunny location for your container-bound Norfolk pine, whether one that you have grown from a seed or one which you have purchased. Choose a window which admits plenty of direct sunlight each day.
Allow the top inch of soil to dry occasionally before you water. Dump any excess water which drains out of the holes in the growing pot.
Turn your tree every couple of days so both sides of the tree get the same amount of sunlight in order to keep your tree growing straight.
Fertilize your tree twice a year, in spring and again during the summer months, giving it a commercial indoor plant fertilizer, following the manufacturer's instructions.
Run a humidifier during the winter when the humidity level in your home typically plummets. Norfolk pines do best when the humidity is approximately 50 percent.
When your tree shows signs of outgrowing its current pot (roots coming out of the drain hole, for example) then replant to a larger pot filled with good quality potting soil.
