  1. Plan by Season: Rotate crops every few months to keep soil healthy and productive.
  2. Mulch Smartly: Organic mulch retains moisture and keeps weeds at bay.
  3. Keep it Organised: Label crops and track what works each year.
  4. Use Row Covers or Cold Frames: Extend growing periods into chilly months.
  5. Regular Feeding: Add slow-release organic fertiliser every 4–6 weeks.
  6. Drainage Checks: Ensure no water pools at the base to prevent root rot.
  7. Mix Heights: Grow low-lying herbs alongside taller staked tomatoes to maximise light.

FAQs

1. Can I use old wood or recycled materials to build my own raised bed?

You can, but ensure materials are untreated and free from chemicals. Alternatively, Aosom offers affordable pre-made wooden raised beds that are rot-resistant and designed for outdoor use, saving you time and ensuring safety.

2. Why aren’t my plants growing well even though I used fresh compost?

While compost is rich in nutrients, growth issues may stem from imbalanced soil structure. Raised beds require more than just compost. A tried-and-tested mix includes 40% compost, 40% topsoil, and 20% perlite or coarse sand. This blend supports drainage, aeration, and root development. Also, check for soil pH, and ensure your planter drains properly—especially important in deeper Aosom beds. Overwatering can compact soil and restrict oxygen to roots, so be sure to strike a healthy balance.

3. How do I rotate crops in my small raised garden?

Crop rotation helps maintain soil health and prevent disease build-up. In smaller raised beds, rotate crops seasonally: start with leafy greens in spring, switch to fruiting plants in summer (like tomatoes or peppers), and follow with root vegetables in autumn. If you’re growing multiple crop types at once, use Aosom’s modular or sectional planter designs to designate zones—making rotation simple and organised from one year to the next.

4. Can I grow fruit in a raised bed?

Of course! Many soft fruits do very well in raised beds. Strawberries, raspberries, blueberries, and dwarf varieties of fruit trees like apples and cherries thrive with good drainage and nutrient-rich soil.
