- How Do I Plant A Hydrangea?
Choose a full sun position with good drainage and moderate shelter for your Hydrangea 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, especially for larger grade plants, to minimise any chance of damaging the roots. Once out, you need to assess the roots before progressing. If they are not all bound up, and haven’t been growing in a circle within the container, place the plant in the hole without removing any of the growing media or cutting the roots. You can tease them apart if you want but this is not essential. If, however, the roots have been circling the inside of the pot or they look totally root bound, simply cut through those very outer roots on either side. You don’t need to be any more aggressive than this or remove any of the growing media. You can try and tease the roots apart, but this generally breaks them which is why we cut them.
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 shrub fertiliser across the soil surface after planting and the give the plant a good watering.

Hydrangea Planting and Growing in NZ
The article discusses how to plant and grow hydrangeas in New Zealand. Here are the key points:
- Choosing the right location: Hydrangeas thrive in a full sun position with good drainage and moderate shelter.
- Preparing the hole: Dig a hole that is 50-75% deeper and wider than the container the plant is currently growing in. Using a planting spade can make the digging process easier.
- Incorporating organic material: It is recommended to incorporate compost or sheep pellets into the soil to provide additional organic material, although this is not essential.
- Fertilizing: Do not put fertilizer in the bottom of the hole. Instead, spread it on the soil surface after planting, preferably when the plant is actively growing in spring.
- Removing the plant from the container: Remove the plant from the container by either pulling it free or cutting the bag. Cutting the bag is recommended, especially for larger grade plants, to minimize the chance of damaging the roots.
- Assessing the roots: If the roots are not bound up or growing in a circle within the container, place the plant in the hole without removing any of the growing media or cutting the roots. If the roots are circling the inside of the pot or look root bound, cut through the very outer roots on either side. Teasing the roots apart is optional but generally breaks them, which is why cutting is preferred.
- Planting the hydrangea: Place the plant in the hole and make sure it is level with the soil surface before filling in around it. Adjust the level by adding or removing soil accordingly.
- Firming the soil: Gradually add more soil and firm it around the plant using gentle pressure.
- Fertilizing and watering: Scatter shrub fertilizer across the soil surface after planting and give the plant a good watering.
These steps provide a general guideline for planting and growing hydrangeas in New Zealand. Remember to consider the specific needs of the hydrangea variety you are planting and adjust the care accordingly.
