Grow Your Own | What to Do In March
Spring is here, and the garden is bursting into life! It’s time to get outside and make the most of this exciting time of year. Read on for our top tips on what to be doing in the vegetable garden in March.
Sowing and Planting
In the greenhouse
Sow winter brassicas in seed trays and tomato seeds in heated propagators. You can now also start your regular sowing of cut-and-come-again salads, to keep you fully stocked with greens for months to come. If you want to give melons a go this year, get these seeds sown in the greenhouse now too. It is also the month to sow fragrant perennial herbs such as lemon-balm, rosemary, sage, thyme and oregano.
Radish seeds can be sown under cloches now. Try something different this year and go for a Bluemoon or Redmoon F1 Hybrid - they will certainly jazz up your salad bowl!
Sow broad beans directly into the ground ready for a delicious summer crop. Kale seeds can also be sown in readiness for a healthy, and on-trend, summer. Whether you are a keen organic gardener or if you simply want to save a bit of money, sowing a comfrey bed now will provide you with organic fertiliser all year. The leaves can be harvested several times a season and can be used as a compost activator, turned into liquid fertiliser, or used as a nutrient releasing mulch.
It’s your last chance to plant bare-root fruit trees this month. Prepare the soil before planting by loosening it with a fork to eliminate compaction and improve drainage. The structure of heavy or sandy soils can also be improved by incorporating some organic matter.
How to plant your fruit trees
1. Remove from container or wrapper.
2. Trim any pot-bound roots and spread out evenly.
3. Dig a hole that is no deeper than the roots, but at least three times the diameter of the root system.
4. Soak the roots for about 30 minutes prior to planting.
5. Place the tree in the middle of the hole and position so that the first flare of roots are level with the soil’s surface. If you plant the tree too deep you will prevent essential air movement to the root system and can make the lower trunk vulnerable to disease.
6. If you are planting a top-heavy tree, insert a stake for support.
7. Refill the hole carefully, placing the soil between and around the roots to prevent air pockets.
8. Firm up gently and water well.
You can also plant asparagus crowns out now. It can take some time to do this job properly, but if treated well, you may be rewarded with 20 years of harvest! Prepare the soil and apply a general fertiliser about a week before planting.
Dig a trench that is 30cm wide and 20cm deep, and then pour soil down the length of it to make a 10cm high mound. Carefully place the crowns on top of the mound, spreading the roots out, 30cm apart. Cover with 5cm of raked soil.
Water thoroughly and keep damp. They won't be ready to harvest for two years, but will be well worth the wait.

Now is a great time to build or buy a compost bin before the growing season and tasks properly kick off.
