How to Grow a Norfolk Pine From Clippings

Answer

Araucaria heterophylla, more often known as Norfolk Island pines, are tropical evergreen trees that are cultivated for their unique, scaled leaf and symmetrical growth habit. These trees are also known as star pines. According to the Urban Forest Ecosystems Institute, they have optimal growth inside the plant hardiness zones 10 and 11 of the United States Department of Agriculture, where they will eventually develop to a height of around 100 feet.

Clippings, also known as cuttings, of Norfolk Island pines may be easily propagated into new plants. For optimal results, cuttings should be begun in the summer. The cuttings will swiftly put on new growth after they have been treated with rooting hormone, which improves their overall performance. According to research conducted by the University of Florida IFAS Extension, it is necessary to take cuttings from the tree’s terminal branch since side branches lead to the development of trees with an uneven and asymmetrical form.

Tip

When it comes to propagating Norfolk Island pine, clippings, also known as cuttings, are your best bet. These take root most successfully when begun in the summer. Rooting hormone should be applied to the cuttings after they have been taken from a terminal branch.

  1. 1. Identify a suitable tip cutting in summer

    Clippings of Norfolk Island pine should be rooted in the summer, when the growth of the current season has begun to develop. Find an appropriate tip cutting on one of the central leaders, which are the vertical stems that are located at the very point of the tree.

  2. 2. Prepare a container

    Before you collect the cutting, you should have a rooting container ready. A mixture of half wet, milled peat moss and half perlite or vermiculite should be used to fill a plastic container that is 6 inches in diameter. Applying pressure on the surface will help to eliminate any air pockets.

  3. 3. Take the cutting and dust with rooting hormone

    Using clean pruning scissors, sever the selected cutting six to eight inches from the tip, and remove the leaves from the lowest third of the stem. Apply some rooting hormone talc to the end that was severed. To shake off any extra powder, gently blow on the stem of the plant.

  4. 4. Plant the cutting into the planting medium

    Create a planting hole in the middle of the wet peat mixture using a sharp object. Create a hole that is sufficiently deep to accommodate the lower portion of the cutting. After dusting the end of the Norfolk Island pine cutting with talcum powder, place it into the hole and pack the mixture firmly against it.

  5. 5. Protect the pot with plastic

    A big plastic bag made of transparent plastic should be used to cover the pot in order to keep the air surrounding the cuttings wet. To prevent the bag from lying on the cutting surface, use wooden skewers to give it some support and prop it up. A rubber band should be used to fasten the bag to the pot. Create a slit in the bag that is a half an inch deep to allow for some air circulation.

  6. 6. Situate the pot in a location with indirect light

    Put the cutting of Norfolk Island pine in a container and place it inside, preferably near a window. Pick a window that lets in plenty of light but not direct sunlight. It is best to keep the cuttings away from windows that face south since the excessive heat will cause them to burn and dry out.

  7. 7. Maintain proper moisture

    Daily spritzing of the Norfolk Island pine cutting will help the leaves retain its natural moisture. When you spray the cutting, it is important to check the moisture level of the peat mixture so that you can guarantee it does not get completely dry. When the top two inches feel mainly dry, water to a depth of three inches. Water should be added.

  8. 8. Open the plastic bag once roots develop

    After six to eight weeks, give the base of the stem a little push to determine whether or not it has established a firm hold on the growth medium via the development of roots. Remove the Norfolk Island pine from its plastic bag and acclimatise it to room temperature and humidity by cutting the bag apart.

  9. 9. Transplant into a larger container

    Transplant the Norfolk Island pine to a protected outdoor location as soon as possible. It should be grown for about one month in its original container before being transplanted into a container that is 10 inches in diameter and is filled with a medium that is light, drains quickly, and has a pH that is somewhat acidic.

  10. 10. Grow under light shade for the first summer, then transplant in fall

    During the first summer of its life, the Norfolk Island pine should be grown in partial shade. To prevent the plant’s leaves from drying out, water it once a week to the depth of one inch and spray it regularly. Either place it in a permanent pot and grow it inside as a houseplant or transplant it into the garden in the fall after the first rain. You can also grow it outdoors.
