Can You Keep A Norfolk Island Pine Small?

Controlling the size of rapid growers like Norfolk Island Pine needs a careful understanding of the growth pattern and factors that can affect it directly or indirectly.

If you mistakenly cut the top, the Pine will stop growing from that point, messing up the prized symmetry.

So do the pruning carefully by keeping shorter branches atop. Meanwhile, gradually keep longer ones at the bottom to restore a symmetrical shape and keep the plant small.

Aim to prune off lateral side branches. While pruning, prioritize older, diseased, drooping, limping, or dying branches, then only focus on shaping the plant.

You can opt for a major pruning session in the active growing season, i.e., Spring and Summer.

Besides pruning, abstain from over-fertilizing the plant as it not only boosts growth but can also harm the plant.

So, infrequent use of slow-release fertilizers is ideal for taming the height of the plant.

Note: Pruning of Norfolk Island Pine is not recommended by many gardeners, as any mishaps in pruning ruin the plant’s stature.
