When to Plant Plum Trees in New Zealand

Plum trees are productive fruit trees that are easy to grow in New Zealand's climate. Their juicy and delicious fruits are acquired tastes to many, but they make excellent preserves, jams, and desserts. Gardeners and homeowners looking to plant plum trees in their gardens or orchards must choose the right time to do so to ensure the trees establish well and produce healthy crops. In this article, we will explore when to plant plum trees in New Zealand and what factors to consider.

Choosing the Right Time to Plant Plum Trees

Plum trees are deciduous, meaning that they shed their leaves seasonally. The best time to plant plum trees in New Zealand is during their dormant period, which is winter. The ideal time to plant is between May and July, depending on where you live. These are the months when temperatures are low, and the trees are in their natural state of rest. Planting during the dormant phase ensures that the trees are less likely to suffer transplant shock and have ample time to develop strong root systems before the growing season.

Factors to Consider When Planting Plum Trees

Planting plum trees in the right season is only one part of the equation. To get the best out of your trees, you need to consider the following factors:

Weather: Check the weather forecast before you plant. You want to avoid planting during a cold and wet spell, which can delay growth and cause root rot.

Soil Type: Plum trees require well-draining soil that is rich in nutrients. Before planting, test your soil to determine its pH levels and adjust accordingly.

Spacing: Plum trees need enough space to grow and mature. Their roots can spread up to twice the tree's canopy. Allow at least 3-4 meters of soil around the tree to give it room to spread.

Pollination: Plum trees need cross-pollination for good fruit set. If you only have space for one tree, consider planting a self-fertile variety like 'Gold' or 'Owen T.' Otherwise, plant two or more compatible varieties that bloom at the same time.

Location: Choose a location that receives full sun and has good air circulation. Avoid planting near structures or in low-lying areas that may be prone to frost damage or waterlogging.

Caring for Your Plum Trees

Once you have planted your plum trees, you need to care for them correctly to ensure they grow healthy and produce a bumper crop. Here are some tips:

Watering: Water your trees regularly, especially during dry spells. Avoid overwatering, which can lead to root rot.

Fertilizing: Fertilize your trees twice a year with a balanced, slow-release fertilizer. Apply in early spring and mid-summer.

Pruning: Prune your trees every year to remove dead or diseased wood, shape the tree, and promote fruiting. Prune during the winter dormant period.

Pest and Disease Control: Monitor your trees for pests and diseases and take necessary action to control them. Common pests that attack plum trees in New Zealand include aphids, leaf curling midge, and thrips. Common diseases include brown rot and bacterial canker.

In Conclusion

Planting plum trees in New Zealand is easy, provided you choose the right time, location, and varieties, and care for them correctly. Remember to check your soil quality, plant in full sun, keep them watered and fertilized, and watch out for pests and diseases. By following these steps, you'll soon have a beautiful and productive plum tree in your garden or orchard!
