Planting Tips

There are many things to consider before you start to plant out your garden. The following is a guide to ensure your plants are given the best chance to perform.

Planting Tips

Hole Preparation

The planting hole must be at least two times the width of the root ball size and no deeper than its current height. This is to ensure the roots have sufficient medium to grow into and the plant has have access to sufficient oxygen which is essential for root growth. Collar rot can also occur if a plant is planted too deep.

Glazing can occur when digging in clay. Glazing occurs when the sides of the hole become smooth acting as a barrier that the roots cannot pass through. Using a fork instead of a spade will break up the “glazing”. If the soil is heavy clay you may have to ensure proper drainage is installed before planting. This is important to ensure the hole does not fill up with water causing the roots to rot and the plant to die.

A good quality planting/garden mix should be used to backfill. If the existing site soil is ok then it can be mixed in with the planting mix. If you are planting natives then use a low phosphorus mix. When backfilling the whole make sure you don’t over compress the soil with your feet. Instead you should lightly compress the soil with your hands.


Most people think that plants get all the nutrients they need from the soil. This could not be further from the truth. It is essential to feed plants in order for them to thrive. We recommend using a slow release fertilizer as well as a soil conditioner such as Seasol. Application rates are different from product to product. Directions will be found on the packaging.


Watering in is essential at this stage of planting. This will allow the soil to settle properly and ensure there are no air bubbles. While the plant establishes itself in it new environment sufficient watering is necessary. It is very common for water not to penetrate the root ball and to only wet the top 10cm of the soil. To ensure that water is getting down to the roots you will need to dig down and check to see if it’s wet. If the soil completely dries out for a period of time it may actually repel water and a wetting agent will need to be applied. Overwatering can also be a problem. In general you should allow the soil to dry out before re-watering.


A layer of mulch is the last step of the planting process. Mulching the soil prevents moisture loss and also provides a barrier for weeds. Much should be applied to 75mm. Form ‘Dish’ around base of plant to retain water. Keep mulch away from base of stem.

These are the basic steps to making sure your plants thrive in your new garden. If you have any other questions of comments about planting, please post on our Facebook page or email us at
