When do I need to re-feed?

The nutrients in SYBASoil will run out in ~6 months on average.

We will advice you on the right fertiliser after doing our plant scan.

When do I repot?

We recommend repotting once any of these things happen:

  • You see roots growing out of the bottom of the pot
  • The soil dries very quickly between watering
  • The plant is top-heavy and wants to fall over
  • Roots are pushing the plant up and out of the container
  • Every 1 to 2 years

What can I expect when using your products?

94.2% of customers report visibly stronger roots& leaf growth within a few weeks.

You will also notice that watering becomes a lot easier due to having the right soil structure.

Why is the soil peat-free?

We don't think peat is so neat!

It becomes too compact over time, leading to a state where it no longer absorbs water.

That's why we opt for coconut fiber and worm castings, keeping your potting soil delightfully airy and usable for much longer. Much more environmentally friendly in its use & less CO2!

🍅 The Perfect Tomato Soil for Healthy Growth & Happy Plants

How Do I Use These Products for My Tomato Plants?

Tomatoes are heavy feeders and thirsty growers, so giving them the right soil from the start can make all the difference. Our Universal Mix is ideal for supporting the fast, nutrient-hungry growth tomatoes are known for — whether you're growing them on a balcony, in a raised bed, or in containers.

To plant tomatoes, start with a deep pot (at least 25–30 cm tall) that has drainage holes. Fill the bottom third with Universal Mix. Place your seedling or young plant into the mix and cover it all the way up to just beneath the first set of leaves — tomatoes love to grow new roots along buried stems. Fill in the remaining space with more mix, press lightly, and water well.

In raised beds or garden soil, Universal Mix can be used to amend poor soil or fill new beds entirely. Its structure helps roots anchor deeply while providing excellent water retention, which tomatoes need during hot summer growth.

Thanks to the mix’s nutrient content and excellent moisture control, your tomatoes will experience fewer dry spells, stronger stems, and more reliable flowering and fruiting throughout the season.

How Does Universal Mix Work for Tomato Plants?

Tomatoes demand rich, loose, and well-aerated soil to thrive. Universal Mix provides a perfect balance of structure, nutrition, and water regulation — ideal for fast-growing crops like tomatoes that don’t tolerate extremes in moisture or nutrient availability.

Here’s how the ingredients support healthy tomato growth:

Coco coir – This sustainable base retains water evenly while allowing excess to drain. Perfect for tomatoes, which need steady hydration but can develop issues like blossom end rot if overwatered or allowed to dry out completely.

Worm castings – A natural fertilizer packed with bioavailable nutrients and beneficial microbes. These castings support root health, boost flowering, and improve resistance to pests and disease. For tomatoes, they encourage more blossoms and larger fruit sets.

Perlite – A lightweight mineral that boosts drainage and aeration, preventing compaction around the roots. This helps tomatoes grow faster and develop stronger stems and root systems.

Lava gravel – Adds structure and important trace minerals like calcium, magnesium, and iron — all essential for healthy tomato development. It also keeps the soil loose and prevents long-term compacting.

Activated carbon – Filters out impurities and helps create a clean root environment. This supports better nutrient uptake and long-term plant health.

Organic nutrients – Slow-release plant food that sustains growth throughout the growing season. It reduces the need for frequent feeding and helps prevent deficiencies that can cause leaf yellowing or poor fruit development.

Together, these components create a healthy, living soil that supports every stage of tomato growth — from seedling to harvest.

The Original Habitat of Tomato Plants

Tomatoes are native to western South America, particularly regions in modern-day Peru, Ecuador, and northern Chile. In their original habitat, tomatoes grew in warm, sunny conditions with well-draining, volcanic or sandy soils that were naturally rich in minerals and organic matter.

These soils didn’t hold water for long but contained enough organic content to support the vigorous growth of wild tomato varieties. Rainfall was seasonal and light, so the plants evolved to thrive in soil that could balance moisture without remaining wet.

Universal Mix replicates many of those same characteristics. It’s mineral-rich, slightly airy, and holds just enough moisture without becoming soggy. It gives your tomato plants a familiar environment that encourages strong roots, flowering, and consistent fruit production — even in less-than-perfect garden conditions.

How to Care for Tomato Plants

Tomatoes are rewarding but do have specific care needs. Here’s how to give them the best growing conditions:

Sunlight: Tomatoes need full sun — at least 6–8 hours per day. The more sunlight they get, the better they’ll grow and fruit.

Watering: Keep the soil consistently moist, especially during flowering and fruiting. Water deeply when the top 3–5 cm of soil feels dry. Avoid splashing water on the leaves to prevent disease.

Feeding: Even with a nutrient-rich mix like Universal Mix, tomatoes benefit from extra feeding during their peak growing season. Use an organic tomato fertilizer or a potassium-rich blend once flowers appear.

Support: Most tomato varieties need support as they grow. Use stakes, cages, or trellises to prevent the stems from bending or breaking under the weight of the fruit.

Pruning: For indeterminate varieties, pinch off side shoots (suckers) that form between the stem and leaf branches to encourage upward growth and bigger harvests.

Pests and diseases: Tomatoes can attract aphids, whiteflies, and fungal issues. Regularly inspect your plants and use natural pest control methods when needed.

Harvesting: Pick tomatoes when they are firm and fully colored. Don’t wait too long — overripe fruit can split or attract pests.

By starting with the right foundation — Universal Mix — your tomatoes get everything they need to grow vigorously and produce delicious, juicy fruit all season long.
