Why Australian Gardeners Are Switching to Grow Bags
Grow bags have become one of the fastest-growing categories in Australian home gardening — and for good reason. Our climate rewards gardeners who can control soil temperature, drainage, and root health. Fabric grow bags deliver on all three fronts in ways rigid plastic pots simply can't match.
Better drainage, less overwatering. Australia's variable rainfall — particularly the heavy downpours common in Queensland, NSW, and Victoria — makes drainage critical. Fabric pots allow excess water to escape from every surface, virtually eliminating root rot without you having to monitor constantly.
Temperature regulation. Black plastic pots can overheat in summer sun, cooking root systems. Breathable non-woven fabric naturally regulates temperature through evaporative cooling, keeping roots in the optimal growth zone even through Australian summers.
Space-efficient and storable. Grow bags fold completely flat when empty — ideal for renters, small courtyards, balcony gardens, or anyone who grows seasonally. Pack them away between seasons and they take up almost no space at all.
Choosing the Right Size
- 1–3 Gallon (4–12L) — Herbs, seedlings, strawberries
- 5 Gallon (19L) — Capsicum, dwarf tomatoes, lettuce
- 10 Gallon (38L) — Tomatoes, cucumbers, zucchini
- 20–40 Gallon (75–150L) — Potatoes, sweet potato, taro
Pair your grow bags with a raised garden bed for a flexible mixed setup, or place them inside a grow tent for climate-controlled year-round growing. All products are shipped from our Melbourne fulfilment centre to customers across Australia.
FAQs
Q: What are grow bags best used for?
Grow bags are ideal for growing vegetables, herbs, and fruit in limited spaces — balconies, courtyards, patios, and rooftop gardens. They're especially popular for tomatoes, potatoes, strawberries, capsicum, cucumbers, and herbs like basil and mint. Because they're portable and foldable, they suit renters and seasonal growers who can't build permanent garden beds.
Q: What size grow bag do I need?
Match bag size to root depth. Small herbs and strawberries do well in 1–3 gallon (4–12L) bags. Most vegetable crops like tomatoes, capsicum, and cucumbers need at least a 10-gallon (38L) bag. Root vegetables — potatoes, carrots, taro — need 20–40 gallons (75–150L) to produce a meaningful harvest. When in doubt, size up: grow bags dry out faster than pots, and larger volumes give more buffer.
Q: Are fabric grow bags reusable?
Yes. Quality non-woven fabric grow bags are designed to last multiple seasons. After harvest, shake out the old soil, rinse the bag with water, and leave to dry completely before storing flat. Most bags handle 3–5 seasons of regular use before the fabric starts to break down.
Q: How often do I need to water grow bags?
More frequently than traditional pots. Because fabric is breathable on all sides, moisture evaporates faster — particularly in warm, dry Australian conditions. In summer, you may need to water daily. Adding a layer of mulch on top of the soil helps retain moisture and reduces watering frequency significantly.
Q: Can I use grow bags inside a greenhouse or grow tent?
Absolutely — grow bags are one of the preferred containers for controlled-environment growing. The air-pruning effect is especially valuable in greenhouse setups where roots can otherwise become overly dense inside rigid pots. For greenhouse and grow tent growers, 10–20 gallon fabric bags on trays work particularly well.
Q: What's the difference between felt and non-woven fabric grow bags?
Both terms refer to breathable, porous fabric containers, and the two are often used interchangeably. Felt bags tend to be slightly thicker and more rigid, holding their shape better when filled. Non-woven polypropylene bags are typically lighter, more affordable, and fold flatter for storage. Both provide the same core benefit — air-pruning and drainage — and both are reusable across multiple growing seasons.
