Squash is a fantastic vegetable to add a pop of colour to your vegetable plot. They come in a variety of different shapes and sizes. As long as you water your squash regularly and plant them in fertile soil, they will be relatively low maintenance and easy to grow. 

Growing Tips:

  • Use moderately heavy soil that drains well.
  • Plant your squash in a sunny area. Avoid shade.


Beetroot is a fantastic root vegetable to grow in March as it will germinate in lower temperatures. This popular vegetable is easy to grow and can be used in various ways. Grate, pickle, roast, or boil the beetroot – either way, it is a delicious vegetable packed full of essential nutrients. 

Growing Tips:

  • Sow the seeds outdoors in a shallow drill.
  • Water the beetroot to regularly to reduce the likelihood of root damage. 
  • Space your beetroot seeds 10cm apart. 


Lettuce is a popular leaf vegetable. There is nothing better than eating a salad packed with fresh, crispy lettuce. So, adding this to your vegetable plot is a must!  March is the perfect time to sow lettuce seeds if you want a crop ready for summer/autumn. 

Growing Tips:

  • If you experience a spell of cold weather, protect the lettuce using a grower frame (available in our online store).
  • Sow seeds in an area of your plot that gets a lot of sun.
  • Water your lettuce early in the morning. Check the soil is dry before you do so. 

Swiss Chard

Swiss chard is a leafy green vegetable that shares similarities with beets and spinach as they are closely related. Not only does swiss chard taste fantastic, but it is also a stunning addition to your veg plot and one that is easy to grow and maintain. 

Growing Tips:

  • Sow seeds thinly in a well-prepared, sunny soil spot.
  • Once you have sown your seeds, cover the soil with 2cm of compost. 

Spring Onion 

Spring onions are a fantastic addition to your veg plot if you have a small, unused area of space. Not only are they quick and easy to grow, but they make a great addition to salads. 

Growing Tips:

  • Prepare the soil before sowing. De-weed and add a good fertiliser. 
  • Avoid overwatering as the spring onions will rot. 
  • Make drills that are around 20mm deep and sow seeds thinly. 


Asparagus is the gift that keeps on giving. It is a perennial, which means its luscious green spears will reappear year after year. Although they are easy to grow, new plants require patience as they take a year or two to settle. 

Growing Tips:

  • Protect the seedlings from pests. Our copper slug bands are the perfect protective barrier. 
  • Keep the asparagus beds weed-free.
  • Avoid mixing with other crops. 

Early Potatoes 

You can start planting early potatoes during the middle of March. They grow fast and also require a lot less space than other varieties of potatoes. Early potatoes are highly rewarding as they taste a lot better than potatoes brought from the supermarket. 

Growing Tips:

  • Enrich the soil by digging in lots of compost. 
  • Ensure potatoes are watered in dry weather conditions. 


Kohlrabi looks very similar to a turnip. It has a crunchy texture and can be green or purple. It is relatively easy to grow as long as you keep it in a sunny spot. 

Growing Tips:

  • Sow indoors for up to six weeks before planting them outside. 
  • Sow one seed 5cm apart from the next.
  • Keep the soil constantly moist.
