Ideal Home’s gardening guide outlines five steps for planting shrubs: soak the roots, prepare the soil, dig a wide hole, set the root ball level with the ground, then water and mulch. Horticultural experts quoted in the report also warn against burying the shrub too deeply, adding organic matter to poorly drained planting holes, or piling mulch against stems.
Ideal Home has published a five-step guide to planting shrubs, drawing on advice from horticultural experts about preparing roots and soil, setting planting depth, and watering after planting. The guidance is aimed at helping gardeners establish shrubs successfully, particularly in autumn, when the report says soil is still warm and moist enough for roots to begin developing before spring.
The first steps are to soak the shrub’s roots and prepare the ground. Paul Parker of J. Parker’s advises dousing the roots in water until they are completely soaked, which he says helps minimise stress on the plant. While the roots soak, gardeners can remove perennial weeds and loosen compacted soil, according to Annelise Brilli, a horticultural expert at Thompson & Morgan.
Next, dig a hole that is about three times as wide as the shrub’s pot and slightly deeper, Parker advises. Loosen soil beneath and around the hole to help roots establish. When placing the shrub, handle it carefully to avoid damaging the roots, and check that the top of the root ball is level with surrounding soil. Brilli suggests laying a cane across the hole as a depth guide. Backfill and firm the soil gently, without pressing hard enough to damage roots.
Finish by watering thoroughly, even if the soil is already damp, to settle soil around the roots. Spread mulch in a wide circle to retain moisture and suppress weeds, but leave about 10 centimetres clear around the stems. Brilli cautions that mulch piled against stems can hold moisture and encourage stem rot. After planting, she recommends watering deeply when needed rather than giving small amounts frequently, with closer checks during dry spells.
Planting Depth Shapes Root Health
The advice focuses on choices made at planting that can affect how well a shrub becomes established. A planting hole that is too deep can deprive roots of oxygen, while a root ball set too high is more exposed to drying out, according to Brilli. Correct positioning and careful backfilling give roots a better chance to extend into the surrounding soil.
Watering and mulch also matter after the initial planting. Newly planted shrubs have not yet developed an established root system, and Brilli says hot, dry spring weather can challenge them as fresh leaves grow and need moisture. The guide’s practical takeaway is to check conditions and water deeply when needed, rather than assuming that planting-day watering is enough.

Why the Guide Favors Autumn
The report describes October as a suitable planting period because soil retains warmth from summer and is generally moister, giving roots time to establish before spring. It presents this as seasonal gardening advice, not a guarantee that every shrub or site will have the same conditions.
The recommendations are attributed to Parker and Brilli and apply to general shrub planting. The source also notes that advice can vary for particular plants, but its experts caution against routinely adding organic matter to the planting hole. In heavy or poorly drained soil, Brilli says, added material may hold excess moisture around roots and can settle as it breaks down, potentially leaving the shrub planted too low.

Conditions Vary by Site
The guide does not specify one watering schedule or a single planting approach for every shrub, soil type or climate. How often a newly planted shrub needs water will depend on weather and local ground conditions; the report advises gardeners to monitor plants, especially during dry spells. Its general steps do not replace care instructions for a particular species or a site with unusually wet or compacted soil.
The source provides expert guidance but no trial data comparing outcomes from different planting methods. Claims about the benefits of soaking roots and the risks of planting depth or mulch placement are attributed to the named experts, rather than presented as results from a reported study.

Monitor Water Through Establishment
After planting, gardeners should check soil moisture and shrub condition as roots develop, giving a deep watering when needed and paying particular attention during dry weather. Keep mulch spread around the plant but away from the stems, and watch for settling soil that might leave the root ball too deeply covered. The report gives no fixed establishment timetable; care should continue according to the shrub’s needs and seasonal conditions.

Key Questions
When does the guide recommend planting shrubs?
It identifies October and autumn as suitable timing, saying soil is still warm and moister, which gives roots time to establish before spring. Local weather and soil conditions can differ.
How wide should the planting hole be?
Paul Parker advises digging a hole about three times as wide as the shrub’s pot and slightly deeper, then loosening soil around and below it.
How deep should a shrub sit?
The top of the root ball should be level with the surrounding soil, according to Annelise Brilli. A cane laid across the hole can help check the height.
Should mulch touch the shrub’s stems?
No. Brilli recommends leaving a 10-centimetre gap around the base. Mulch piled against stems can trap moisture and encourage stem rot.
Should organic matter go in the planting hole?
Brilli advises against routinely adding it, particularly in heavy or poorly drained soil, where it may hold excess moisture and settle as it breaks down.
