There is nothing quite as exciting as bringing home new plants to enrich your garden and lift its appearance. With a good selection to choose from, creating a thriving garden is achievable for anyone, whatever your level of experience.
To ensure your new plants grow well and hold their beauty over time, they need proper planting and ongoing care tailored to their specific needs. In this guide we work through the essential steps: soil preparation, best planting practice, and the post-planting care that promotes healthy growth and long-lasting vitality.
With the right approach, you can create a garden that stands out, showcasing both your own style and the plants you have chosen. The first month after planting matters more than any month that follows, so it is worth doing carefully.
Selecting the right plants for your garden
Before you begin planting, it is essential to choose plants that suit your garden's conditions and the outcome you want. Consider how much sunlight the chosen area receives, your soil type, your climate and how much water is realistically available.
By selecting plants specifically adapted to your garden's conditions, you will not only enjoy far better success rates but also minimise the ongoing resources and maintenance the garden demands. If you are unsure how large something will arrive, our plant size guide sets out what each pot size looks like in practice.
Preparing the soil for optimal plant growth
One of the most crucial factors in successful planting is proper soil preparation. Good soil promotes healthy root development and allows plants to access vital nutrients, oxygen and water. These are the steps that make the difference.
- Assess and amend your soil: evaluate your soil's texture and structure to identify any amendments needed. If your soil is too heavy with clay or too sandy, incorporate organic matter such as well-aged compost or well-rotted manure to improve structure and increase nutrient availability. Test the pH and amend accordingly with lime to raise it or sulphur to lower it if necessary.
- Remove weeds and debris: to minimise competition for water, sunlight and nutrients, clear the planting area of weeds and debris. Dig out any deep-rooted weeds to prevent regrowth and ensure a clean slate for your new plants.
- Loosen and aerate the soil: compacted soil impedes root penetration, water infiltration and aeration. Use a garden fork to loosen the soil in the planting area to a depth of roughly 30cm to 45cm, giving your plant's roots plenty of room to grow.
- Fertilise the soil: incorporate a slow-release, balanced fertiliser into the soil according to the label instructions. Always consider the specific needs of your selected plants, since natives in particular resent high-phosphorus feeds.
Our detailed guide to preparing the soil for planting covers each of these steps in more depth, including how to tell when a bed is genuinely ready.
Planting techniques to promote healthy growth
Now that your soil is prepared, it is time to plant. Follow these basic techniques to give your plants the best possible start.
- Dig a suitable hole: create a hole slightly wider and deeper than the plant's root system to encourage roots to spread. Loosen the soil at the bottom of the hole to help drainage and root growth.
- Position the plant correctly: gently remove the plant from its container, taking care not to damage the roots. Place it in the hole with the top of the root ball level with the soil surface. For container-grown plants with compacted roots, tease them apart gently before planting to encourage new growth into the surrounding soil.
- Backfill and water: fill the hole with the prepared soil, firming it gently around the plant to eliminate air pockets without over-compacting. Water thoroughly immediately after planting to settle the soil and hydrate the root system.
If you are moving an established plant rather than putting in a new one, the rules change considerably. Our guide to transplanting trees and shrubs explains how to reduce transplant shock.
Ongoing care and maintenance for long-lasting beauty
After planting, ongoing care is essential for maintaining health and vigour. These are the key habits that keep a new garden moving forward rather than standing still.
- Watering: develop a consistent schedule based on your plants' needs, local weather and the season. Monitor soil moisture and adjust accordingly, providing a thorough soak rather than shallow, frequent watering. Overwatering kills more new plants than drought does, and our guide to overwatering and root rot explains how to tell the difference.
- Mulching: apply a layer of organic mulch such as bark chips, lucerne hay or sugarcane around the base of your plants to conserve soil moisture, moderate soil temperature and suppress weeds. Keep the mulch a few centimetres clear of plant stems to discourage collar rot.
- Fertilising: apply regular, balanced fertilisation so your plants have access to the nutrients they need. Be mindful of each plant's specific requirements and adjust your feeding schedule accordingly. Over-fertilising causes more harm than good, so follow product instructions carefully to prevent burning roots or creating nutrient imbalances.
- Pruning and deadheading: prune regularly to maintain a good shape, promote healthy growth and encourage flowering. Remove dead or damaged branches, along with any new growth that disrupts the desired form. For flowering plants, deadhead spent blooms to encourage further flowering rather than seed production. Our pruning guide for beginners is a good place to start if you have never done it.
- Monitoring for pests and diseases: watch for signs of pests or disease, which cause significant damage if left untreated. Treat infestations promptly with appropriate control methods such as horticultural oil, pruning of affected limbs, or a registered fungicide.
One thing worth knowing in advance: newly planted stock often shows crisp brown leaf margins in its first few weeks, particularly after a hot or windy spell. This is usually transplant stress rather than disease, and our guide to understanding leaf burn explains how to tell it apart from something more serious.
Common first-year mistakes
Planting too deep. Burying the root ball below the surrounding soil level is the single most common error, and it slowly suffocates the plant. The top of the root ball should sit level with the soil, or very slightly proud on heavy clay.
Watering little and often. A daily sprinkle keeps moisture in the top few centimetres and teaches roots to stay shallow, which leaves the plant helpless in its first hot spell. Water deeply and less frequently instead.
Feeding too early. A newly planted specimen has a damaged root system and cannot use a heavy feed. Wait four to six weeks, then apply a light dose of slow-release fertiliser.
Skipping the stake, or leaving it on forever. Tall plants in windy positions need support for their first year so the roots can knit in, but a stake left in place for three years produces a weak trunk that has never had to hold itself up. Remove it once the plant is anchored.
