How calcium and magnesium support stronger plant structure, greener leaves, nutrient uptake and plant resilience

Practical grower guide

When can Cal-Mag help?

Additional plant support

🌱
Active new growthSupports plants producing new leaves, stems and roots.

🍅
Heavy-feeding plantsUseful for productive crops such as tomatoes, capsicum and citrus.

🍃
Possible deficiency signsConsider it when new growth is distorted or older leaves yellow between the veins.

Common warning signs

Signs your plants may need Cal‑Mag

Watch for these symptoms during active growth, flowering and fruit development. Open a card to see what to look for.

Blossom end rot

Dark patch underneath developing fruit.

What to look for

Dark, sunken tissue develops at the blossom end of tomatoes, capsicum and similar fruit.

Yellowing between veins

Yellow leaf tissue with greener veins.

What to look for

Older leaves may turn yellow while their main veins remain noticeably greener.

Deformed new leaves

Fresh growth appears curled or misshapen.

What to look for

Young leaves may emerge twisted, curled, crinkled or unusually small.

Poor root development

Slow establishment and a weak root system.

What to look for

Roots may remain short, sparse or poorly branched, causing plants to establish slowly.

Poor fruit set

Fewer flowers successfully develop into fruit.

What to look for

Flowers may drop or develop into fewer, smaller or lower-quality fruit.

Brown leaf edges

Leaf margins become dry, brown or brittle.

What to look for

Dry or scorched margins can appear during nutrient stress, although this symptom is not specific to Cal-Mag.

i
These symptoms are not exclusive to calcium or magnesium shortages. Watering, damaged roots, unsuitable soil pH, pests and other nutrient imbalances can look similar. Use Cal-Mag as additional support rather than as a complete fertiliser.

Ive got a mix of veggies, citrus and garden beds, so the smaller kits never lasted very long. This one has been much better for me. The sprayer is easy to use and gets the whole garden done pretty quickly.

Really happy with this bundle so far. I use the 20-20-20 for most of the garden and the Cal-Mag separately on my tomatoes and capsicums. Everything is looking greener and growing well.

The Garden Growth Bundle includes 4L of All Purpose 20-20-20 Liquid Fertiliser, 1L of Cal-Mag Nutrient Supplement and a reusable 1L hose-end fertiliser sprayer. It provides a simple feeding system for medium-sized home gardens, vegetable beds, citrus trees, fruiting plants, flowers, shrubs and ornamentals.

Which plants can I use this fertiliser bundle on?

This bundle is suitable for most plants in a mixed home garden, including vegetables, herbs, tomatoes, capsicums, citrus trees, fruit trees, flowering plants, shrubs and established garden beds. Use the balanced All Purpose fertiliser for regular feeding, with Cal-Mag applied separately when fast-growing or heavy-feeding plants need extra calcium and magnesium support.

How do I mix the fertiliser in the hose-end sprayer?

For All Purpose 20-20-20, add 150ml for light feeding, 250ml for medium feeding or 300ml for heavy feeding, then fill the 1L bottle with water. For Cal-Mag, mix 100ml with 900ml of water.

How often should I feed my garden?

Feeding frequency depends on the plant type, growth stage, weather and soil conditions. The All Purpose 20-20-20 fertiliser can be used as your regular garden feed, while Cal-Mag is best used separately when plants require additional nutrient support. Start with a light or medium feed and adjust based on how your plants respond.
