Planning and Designing Your 30 m² Garden
Site Selection and Sunlight Requirements
Choose a spot that gets 6 to 8 hours of direct sun each day.
Vegetables thrive in full light so check sun patterns in your yard.
Pick south-facing areas if you live in the northern hemisphere.
Make sure the garden sits near a water source for easy access.
Place it where you can reach it without hassle for weeding and harvesting.
Protect from strong winds using fences or hedges.
Consider microclimates some spots stay warmer or cooler.
- Sunlight helps plants grow strong and produce more food.
- Good access saves time on maintenance tasks.
- Wind protection keeps plants from drying out too fast.
Garden Shape and Layout Options
A 30 m² garden works best in rectangular or square shapes.
These designs use space well.
Try raised beds for better soil control and fewer weeds.
Set up four beds each 1.2 m by 2.4 m to cover about 29 m².
Use in-ground rows for bigger plants like corn or squash.
Space rows to walk between them easily.
Square foot gardening divides space into 1-foot grids for dense planting.
A full 30 m² setup holds around 300 plants.
Keyhole gardens form a circle with a compost basket in the middle.
They save water in dry areas.
Add vertical gardening with trellises for climbers like beans or cucumbers.
This frees up ground space.
Layout Type | Best For | Key Benefit |
|---|---|---|
Raised Beds | Beginners | Easy soil management |
Square Foot | Small spaces | High plant density |
Keyhole | Dry climates | Water retention |
Vertical | Limited ground | Saves floor area |
Zoning and Companion Planting
Group plants by their needs in the 30 m² garden.
Put sun lovers like tomatoes and peppers in the brightest spots.
Place shade-tolerant ones like lettuce and spinach in partial shade.
Use companion planting to help plants grow better together.
Basil boosts tomatoes while carrots pair well with onions.
Keep potatoes away from tomatoes to avoid shared pests.
Intercrop fast growers like radishes between slow ones like broccoli.
This fills space without waste.
- Tomatoes with basil deter bugs.
- Carrots and onions hide from pests.
- Radishes mature quick for quick harvests.
