Harvesting peas and beans is a rewarding process. Depending on the variety, you will typically start to see pods forming within a couple of months. When the pods are plump and feel full, carefully pick them from the plant. Don’t be afraid to taste a few straight from the garden—they’re at their freshest and sweetest right after harvest!
Peas and beans are versatile vegetables that can be enjoyed in various dishes. Add them to salads, stir-fries, or soups for a burst of flavor and texture. You can also preserve them by blanching and freezing for later use.
So, if you’re ready to start your March vegetable garden, don’t forget to include peas and beans in your planting plans. With their ease of cultivation and delicious rewards, these legumes are a must-have for any garden enthusiast.
Herbs
Why not add some fresh herbs to your garden this March? Herbs like parsley, basil, and chives are perfect choices to grow during this time of year. Whether you prefer to sow them indoors or directly in the garden, these aromatic plants will not only enhance the flavor of your dishes but also attract beneficial insects to your garden.
When growing herbs in March, it’s important to provide them with the right conditions for healthy growth. Be sure to choose a sunny spot in your garden or a well-lit area indoors. Herbs generally prefer well-draining soil, so consider adding some organic matter or compost to improve the soil’s quality.
To sow herbs indoors, fill small pots or trays with seed compost and place a few seeds in each container. Lightly cover the seeds with a thin layer of compost, water gently, and cover with a plastic bag or clear lid to create a mini greenhouse effect. Place the pots in a warm spot, such as a windowsill, and keep the soil moist but not waterlogged.
If you prefer to sow herbs directly in the garden, prepare the soil by removing any weeds and loosening it with a garden fork or tiller. Follow the seed packet instructions for proper spacing and depth, as it may vary depending on the herb.

When it comes to harvesting your homegrown herbs, do so regularly to encourage further growth. Snip off the leaves or sprigs as needed, starting from the top of the plant. Not only will this promote new growth, but it will also provide you with an abundance of fresh herbs to use in your culinary creations.

By following these tips and dedicating a little time and care, you can enjoy a thriving herb garden throughout the year. Whether you’re adding them to your favorite recipes or simply enjoying their enticing aromas, herbs are a delightful addition to any garden.
Brassicas
March is the perfect time to plant brassicas, such as broccoli, cabbage, and kale in your vegetable garden. These cold-hardy vegetables thrive in cooler temperatures and offer an array of nutrients that are beneficial for your health. Whether you prefer the crispness of cabbage or the earthy flavor of kale, growing brassicas can be a rewarding experience.
There are two ways to grow brassicas: from seedlings or by direct sowing. If you choose to start from seedlings, you can find a wide variety available at your local garden center or nursery.

Here are a few popular brassica varieties to consider planting in March:
- Broccoli: This nutrient-rich vegetable is packed with vitamins and minerals. Choose from varieties like ‘Calabrese’ or ‘Purple Sprouting’ for an abundant harvest.
- Cabbage: With its versatile nature, cabbage is an excellent addition to any kitchen garden. From traditional ‘Savoy’ cabbage to nutrient-dense ‘Red Cabbage,’ there’s a variety to suit every taste.
- Kale: Known for its rich flavor and high vitamin content, kale is a superfood that is easy to grow. Consider varieties such as ‘Curly Kale’ or ‘Cavolo Nero’ for your garden.
By following these tips and selecting the right brassica varieties, you can enjoy a delicious and nutritious harvest of these cold-hardy vegetables. Don’t forget to share your garden-to-table creations with family and friends!
Onions and Shallots
In March, it’s the perfect time to plant onions and shallots in your garden. These alliums require a longer growing season, making early planting essential for a bountiful onion harvest later in the year. I will share expert tips on preparing the soil, spacing, and caring for onions and shallots during their growth.
If you’re looking to add some flavour and versatility to your meals, onions and shallots are must-have crops in your vegetable garden. Both of these members of the allium family can be planted in March to give them sufficient time to establish their roots and grow before the summer heat sets in.
The first step in growing onions and shallots is to choose high-quality sets or bulbs. Look for varieties that are suitable for spring planting and have a good storage life. Before planting, ensure that the soil is well-drained and enriched with organic matter. Onions and shallots thrive in soil that is slightly acidic, with a pH level between 6.0 and 6.8.
When planting, create furrows in the prepared soil and space the sets or bulbs according to the variety’s recommended spacing. This ensures that there is enough room for the onions or shallots to develop fully. Gently cover the sets or bulbs with soil, making sure they are planted at the correct depth. Water the newly planted onions and shallots thoroughly to help them settle into their new environment.
Throughout their growth, it is important to keep the onions and shallots well-watered. Onions have shallow roots, so they require regular watering, especially during dry spells. A layer of mulch can help conserve moisture in the soil and suppress weed growth. However, be careful not to cover the bulbs or sets with mulch as this can cause rotting.
Onions and shallots are relatively low-maintenance crops, but they do benefit from occasional feeding. Apply a balanced fertilizer once or twice during their growing season to provide them with the necessary nutrients. Be mindful not to over-fertilize as this can result in excessive leaf growth and fewer bulbs.
To harvest onions, wait until the tops start to flop over and turn yellow. Gently loosen the soil around the onions and lift them out of the ground. Allow them to dry in a well-ventilated area for a week or two before storing them in a cool, dry place. Shallots can be harvested when the tops turn brown and start to fall over. Lift the shallots from the ground and similarly dry and store them.
With the right care and attention, you can enjoy a plentiful supply of delicious onions and shallots from your own garden. Whether they’re making your salads more flavourful or adding depth to your cooked dishes, these versatile alliums are a staple in every kitchen.
Planning and Preparation
Before diving into gardening in March and starting your vegetable planting, it’s crucial to plan and prepare your garden beds. Proper planning and preparation lay the foundation for a successful harvest. In this section, I will provide you with guidance on selecting the right location, preparing the soil, and using organic fertilizers to create optimal growing conditions for your vegetables.
