Understanding the Problem

Why salinity matters
in Swan Hill gardens

Dryland salinity is one of the most widespread challenges for Swan Hill gardeners. It happens when rising groundwater carries naturally occurring salts up through the soil profile. As that water evaporates at the surface, the salt stays behind — making the topsoil progressively harder for plants to grow in.

It's not just farm country that's affected. Many residential blocks in and around Swan Hill have some degree of salinity — sometimes obvious (bare patches, white salt crust on the soil), sometimes subtle (plants that struggle for no apparent reason despite regular watering).

Peta-Lyn & John's Story

When the Nosattis took on the old dairy farm block just outside Swan Hill in 1981, salinity was a serious challenge. The cleared land had rising groundwater, difficult soil, and areas where plants simply wouldn't grow.

Over 45 years they've trialled hundreds of plants, learned what works, and built a 3-acre oasis that proves what's possible in the Mallee — even on a saline block — when you choose the right plants and work with the land rather than against it.

"The salt isn't going to go away overnight. But the right plants don't just cope with it — some of them actually love it."

— Peta-Lyn Nosatti

Salinity Levels — A Practical Guide

Low
2–4 dS/m · Mild salinity Common in many Swan Hill residential gardens. A wide range of salt-tolerant species will perform well. Natives, Mediterranean herbs, and many ornamentals are viable choices.
Moderate
4–8 dS/m · Significant salinity More common on rural blocks and low-lying areas. Plant selection becomes more important. Stick to species with documented moderate-to-high salt tolerance.
High
>8 dS/m · Severe salinity Challenging but not hopeless. True halophytes — plants that have evolved for saline conditions — will thrive where nothing else can. Saltbushes, Melaleuca lanceolata, and a handful of others are your best allies.

Not sure what your salinity level is?

You don't need to test before you visit. Describe your block to Peta-Lyn or John — where the problem areas are, what's struggled or died, what the soil looks like — and they'll give you a practical read on what you're dealing with. Bring photos if you have them.

Before You Plant — Four Rules for Saline Sites

⛰️
Plant on raised mounds
Even 20–30cm of better soil creates a low-salinity establishment zone. This single step makes the biggest difference on difficult blocks.
💧
Water deep, not often
Shallow watering keeps roots near the surface — where salt concentrates as water evaporates. Deep, infrequent watering pushes roots down into less saline soil.
🌾
Mulch generously
Heavy mulching reduces soil evaporation — the mechanism that concentrates salts. A 10cm layer of coarse mulch makes a measurable difference.
🌱
Establish with fresh water
If your bore water is salty, use rainwater or town water for the first 6–12 months. Once established, most salt-tolerant plants can cope with saline irrigation.
