Do Gardenias Grow In New Zealand?

Gardenias grow well in New Zealand, though they do prefer the warmer regions. In colder climates they can experience frost damage, particularly when they are small. That said, they will cope with moderate frosts the following season after plantings.

Some varieties of Gardenia are better suited to New Zealand growing conditions than others:

Where Are Gardenias Native To?

Gardenias are native to tropical and subtropical regions of Africa, Asia, Madagascar, Pacific Islands, and Australia. There are over 140 species of Gardenia, and they are found in a wide variety of habitats, including forests, woodlands, and coastal areas. Some of the most well-known Gardenia species include:

How Do I Plant A Gardenia?

Choose a full sun position with good drainage and moderate shelter for your Gardenia plant. The hole should be dug to at least 50-75% deeper and wider than the container the plant is currently growing in. A planting spade makes the hole digging a lot easier. The Plant Company recommends incorporating compost or sheep pellets into the soil to provide additional organic material, but this is not essential. Do not put fertiliser in the bottom of the hole, rather spread that on the soil surface after planting, and preferably do this when the plant is actively growing in spring.

Remove the plant from the container it is growing in by either pulling it free or by cutting the bag. We recommend cutting the bag or container, especially for larger grade plants, to minimise any chance of damaging the roots. If the roots have been growing in a circle or are all bound up you can tease them apart if you want but this is not essential. Similarly, you don’t need to remove any of the growing media. The Plant Company does not recommend cutting the roots, even if the plant is root-bound as this offers no benefit. This is explained in our article, Managing Rootbound Plants.

Now place the plant in the hole and make sure it is level with the soil surface before filling in around it. If it is above the soil surface, dig more out. If it is below, put in more soil and retest the level. Once the plant is set level with the soil surface, add more soil gradually and firm it around the plant using gentle pressure as you go. Scatter fertiliser for acid loving plants across the soil surface after planting and the give the plant a good watering.

Do Gardenias Grow Quickly?

Gardenias are generally considered to be moderate growers, meaning they won't explode in size overnight. They typically add somewhere between 30-60 cm of growth per year until they reach maturity. However, the exact growth rate will depend on the variety of Gardenia, the climate, and the quality of the soil. They thrive in full sun and with a well-drained soil. Here are some tips for encouraging your Gardenia grow quickly:

With proper care, your Gardenia plant should grow quickly and provide you with years of enjoyment.

Where Do Gardenia Grow Best?

A full sun position with good drainage is essential for getting the best results with Gardenias. On poorly drained sites or with over-watering they tend to become stunted, sickly looking, and may even die. In partial shade conditions they can be become “leggy” and flowering is often reduced. The position should also be moderately sheltered so fresh growth is not damaged by wind, and this will help produce a better shaped plant overall. They are generally regarded as frost tolerant, though alpine environments or areas that experience very heavy frosts should be avoided.

What Is The Best Fertiliser For Gardenia?

Gardenias are lush plants that require feeding to keep them growing optimally and they do require an acidic fertiliser. The Plant Company’s fertiliser for acid loving plants has been blended to give plants an initial boost and then sustained nutrition for 12-months. We recommend the fertiliser is applied to the soil surface in spring just as the plants start to grow actively. More importantly, we advise that no fertiliser is placed in the hole at planting, but rather spread around the soil surface so it can wash through the roots as it releases. This Plant Company’s fertiliser for acid loving plants ensures that nutrients remain in the soil around the plant rather than being lost through the soil profile to where the plant cannot reach it. This also applies to plants grown on sandy soils. The Plant Company’s fertiliser is therefore very environmentally friendly and longer lasting than most other products in the market.

Foliar feeding using a liquid fertiliser can be undertaken if you have time but this is not essential if acid fertiliser has been applied. If you think the plants need an extra boost or have some yellowing, however, a liquid fertiliser application won’t hurt. A great benefit of foliar feeding is that it helps keep the leaves strong and lush.

What Is The Best Fertiliser For Gardenias Grown In A Pot

Gardenias grown in containers require different fertiliser to those grown outdoors in soil. In this instance the correct fertilisers to use are either the container plant fertiliser or fertiliser tablets. Each of these will provide safe, sustained, and complete nutrition to the plant for the next 12-months. Using other types of fertiliser can be detrimental to the plant and may result in plant injury or death.

Foliar feeding using a liquid fertiliser can be undertaken if you have time but this is not essential if container plant fertiliser or fertiliser tablets have been used. If you think the plant needs an extra boost or has some yellowing, however, a liquid fertiliser application won’t hurt. A great benefit of foliar feeding is that it helps keep the leaves strong and lush as the nutrition is right where the plant needs it.

What Is Causing The Gardenia Leaves To Yellow?

Leaf yellowing, which often occurs during winter with Gardenias is the result of a lack of magnesium in the leaves. The colder weather restricts the uptake of this nutrient through the roots and results in the leaves developing yellow tones. The issue is easily fixed with a liquid feed that contains magnesium. After 2-3 applications the issue should be resolved. A lack of nitrogen will also cause similar symptoms, which again will be corrected with a liquid feed and fertiliser for acid loving plants.

Leaf yellowing can also result from Gardenias being over-watered, poor drainage, or both. They will also develop yellow leaves if they have not been watered for some time, but this is usually coupled with leaves dropping. Other common causes are too much shade, or the plants have not been fed for several years. A liquid fertiliser can be used to correct issues quickly and should be supported with fertiliser for acid loving plants during spring if you think this is the cause.

Pests sucking on the leaves can cause leaves to yellow, but this is often mottled and varied across the plant. Inspect the leaves for scale insect, aphids, thrips, and whitefly mainly, and be sure to check the underside of the leaves. These are all easily controlled with an insecticide.

Are Gardenia Plants Expensive?

Gardenia Propagation

Gardenia are easily propagated from stem cuttings. Semi-hardwood cuttings are usually taken from autumn until mid-spring. A stem about 8-10 cm long is trimmed into a cutting using secateurs with 2-3 leaves at the top and just below a node. A nick is taken off the base of the cutting to expose more tissue. The cutting is dipped in rooting hormone for 5-10 seconds and then inserted into propagation growing media. The tray of cuttings is placed under mist with bottom heat also applied. The cuttings will have taken root inside of five weeks as a rule.
