As a gardener based in Staffordshire with over 15 years of experience, I've helped countless clients transform their gardens into flourishing landscapes. Today, I want to share some tips on how to plant up a herb planter, a rewarding project that provides fresh herbs throughout the year.

Quick Answer

To plant a herb planter, choose a sunny spot, use well-draining compost, and select herbs that thrive together. Water regularly and ensure good air circulation.

Choosing the Right Container

When it comes to herb planters, size matters. Ideally, opt for a pot that's at least 30cm in diameter to allow your herbs ample space to grow. If you're in the Midlands, where the weather can be quite variable, consider containers that can be moved to shelter during harsh weather.

Soil and Compost Selection

Herbs prefer well-draining soil. I recommend using a mix of multi-purpose compost with some added grit or perlite. This ensures the roots don't sit in water, which is crucial during the wetter months in the UK.

Choosing Your Herbs

Select herbs that suit your culinary preferences and can coexist happily. Here's a quick guide:

Mint None Plant separately; it's invasive.

Planting Technique

Before planting, ensure your container has drainage holes. Fill the bottom with a layer of stones for extra drainage. Place your herbs in the compost, ensuring they're at the same depth they were in their nursery pots. Water them in well.

Care and Maintenance

Herbs require regular watering, especially during dry spells. In Staffordshire, the summer can be unpredictable, so checking your planters daily is a good practice. Rotate the pots periodically to ensure even growth.

  • Water regularly but avoid waterlogging.
  • Feed with a liquid fertiliser every few weeks during the growing season.
  • Trim herbs regularly to encourage bushy growth.

Seasonal Considerations

In the UK, the best time to start a herb planter is in late spring after the last frost. However, with a bit of protection, hardy herbs can be planted earlier. In the Midlands, herbs like rosemary and sage can often survive milder winters outdoors.

Frequently Asked Questions

Can I grow herbs indoors?

Yes, herbs can thrive indoors if they receive sufficient light, ideally a south-facing windowsill.

How often should I water my herb planter?

Watering frequency depends on the weather. In dry spells, daily watering might be necessary. Otherwise, every few days should suffice.

What should I do if my herbs are growing too tall and leggy?

Trim them back to encourage bushier growth and prevent them from flowering too soon.
