If your tomato plants look healthy but your fruit is inconsistent, bland, or slow to ripen, it’s usually not a “you” problem. It’s a nutrition timing problem.
Tomatoes are heavy feeders with a clear seasonal rhythm. The nutrient balance that builds strong leaves early on is not the same balance that produces big, flavourful, firm fruit later in the cycle.
That’s why a targeted fruiting formula can make such a visible difference once your plants move into flowering and early fruit set.
Why tomatoes need more than a general fertiliser
Tomatoes have three key phases:
Vegetative growth: leaf and stem building
Flowering: strong bloom development and reliable fruit set
Fruiting: size, colour, sweetness, firmness, and yield
A general fertiliser can work early, but during bloom and fruiting, tomatoes tend to respond better to a formula that prioritises phosphorus and potassium.
The formula that fits tomato priorities
Our go-to for high performance fruiting fertiliser is:
NEW Advanced Formula – NPK 4-18-38 + Calcium & Magnesium
It’s designed to support:
Better fruit size and colour
Firmer tomatoes, supported by Calcium & Magnesium

Tomatoes are notorious for quality issues when calcium uptake becomes inconsistent, especially in:
A fruiting formula that includes Calcium & Magnesium support helps take pressure off your routine and makes it easier to maintain consistent fruit quality across the season.
A simple feeding rhythm that works
You don’t need complicated schedules. For most growers, a steady approach wins:
Begin feeding once plants are established
Stay consistent through flowering and fruiting
Apply on a regular cycle rather than big occasional doses
