Beginner’s Guide: What to Buy for Starting a Container Garden from Scratch

So You Want to Start a Container Garden? Let’s Go Shopping

Setting up a successful container garden does not need to be complicated, but it does require the right gear from the start. Whether you’ve got a sunny balcony, a courtyard, or a corner on the patio, these are the exact things we’d buy if I were starting from scratch.

All items listed are beginner-friendly, affordable, and designed to give your plants the best possible start.

‍

1. A Premium Potting Mix That Does the Heavy Lifting

Why it matters:
Soil is your foundation. In container gardening, the quality of your mix is even more important than in-ground beds because plants rely entirely on what’s in that pot.

What to look for:

• A lightweight, free-draining mix that retains moisture
• Added fertiliser or organic matter for early plant growth
• A mix specifically labelled for containers or pots

Recommendation: A high-quality mix like Searles Premium Potting Mix

• Rich in organic ingredients and fertilisers
• Holds moisture evenly
• Offers excellent drainage and aeration for potted roots

Takeaway: Don’t skimp on potting mix. This is your biggest investment for a flourishing container garden.

‍

2. Pots and Containers (Yes, Size Does Matter)

What you need:

• Pots with proper drainage holes (no exceptions)
• Materials that suit your climate: terracotta, ceramic, plastic or grow bags
• Sizes that match your available space and the plant’s mature root system

Top tip: Start with a few versatile containers (25–40 cm wide) for herbs and leafy greens. Upsize for tomatoes or larger flowering plants.

Takeaway: Bigger pots offer better soil volume, less watering stress and more room for roots to grow.

‍

3. Easy-Grow Plants That Build Your Confidence

When you’re just getting started, go for quick wins. Choose plants that are low-maintenance and reliable.

Best beginner plants for containers:

• Herbs: basil, mint, chives, parsley
• Leafy greens: lettuce, rocket, spinach
• Flowers: marigolds, pansies, calendula
• Compact veg: cherry tomatoes, dwarf chillies, radish

How to choose:
Pick based on your light levels (full sun, part shade) and your climate. Check plant labels or ask your local nursery.

Takeaway: Starting with success makes you more likely to stick with it and keep growing.

‍

4. The Right Fertiliser for Long-Term Growth

Here’s where many beginners slip up: They forget that potting mix nutrients get used up fast. If you want healthy, productive plants, you must feed them regularly.

Recommendation: Searles 5 IN 1 Organic Fertiliser Pellets

• Easy to apply - just sprinkle on top
• Contains composted manures, seaweed and trace minerals
• Feeds slowly for up to 3 months

Use after your plants are established, usually 3–4 weeks after planting.

Takeaway: In a pot, fertiliser is not optional - it is essential.

‍

5. Basic Tools You’ll Actually Use

You don’t need much to get started, but a few basics make the job easier and more enjoyable.

Essential items:

• A good watering can with a narrow spout
• Lightweight gardening gloves
• Secateurs or sharp scissors
• Optional: a hand trowel and a moisture meter

Takeaway: Simple tools save time and keep your hands clean and your plants happy.

FAQs: Starting a Container Garden

Can I use soil from my garden in pots?

No. Garden soil is too heavy and can compact in containers, restricting root growth. Always use a premium potting mix designed for pots.

How often should I water my containers?

It depends on the plant and pot size, but most containers need watering every 1–2 days in summer, and less in winter. Use your finger to check soil moisture before watering.

How do I stop water pooling in my pots?

Make sure your pots have drainage holes and are not sitting in saucers of water. If your mix still holds too much water, replace the potting mix if it is old or add Searles Peneraide Re-Wetting Granules to aid water absorption into the soil and add fertiliser at the same time.
