Finally, it’s time to get your early vegetables growing if you want to savor the wonderful fresh taste of new vegetables this spring.

Keep in mind, however, not all vegetables can be started early.  Many, like bush and pole beans, need warmer soil temperatures for good germination and successful growth. At this time of year, you should be using raised beds of eight to 10 inches, and it is essential to have good soil preparation and drainage.

Even though many seed catalogues recommend a later start, broad beans can be planted now.  These large beans love cooler soil temperatures and mature early in the spring before the weather becomes too warm.

Early brassicas (cabbage, cauliflower, broccoli and kale), can be under way now as well.  They do best from seedlings started indoors, but it’s important to use only early varieties at this time of year as they are bred to withstand cool conditions. Brassicas are lime lovers, so use plenty of Dolopril in the rows. If root maggots have been a problem in the past, try adding fir or hemlock bark mulch and sand to improve the openness and porosity of the soil.

Lettuce is possibly the oldest, most popular of all vegetables. It will grow under a wide diversity of conditions, but prefers cool growing temperatures of between 50 and 60 degrees F.  You can seed it directly in the ground later on, but for early crops, it’s best to transplant seedlings.

Leaf lettuce is faster maturing than head types.  Try some of the new ‘loose head’ varieties like ‘Buttercrunch’ and for an interesting change, plant some of the new vibrant red-leafed varieties – they really colour up both the garden and a salad bowl.

Sweet Spanish onions won’t be as sweet unless they are in the ground soon. You can seed them directly, but I prefer transplants to save both thinning and time. Many varieties are now available, but remember:  some are good keepers while others are not. You may also want to try Kelsae Giant, the world’s largest onion – they are quite something!  They all prefer a light, sandy loam and the hottest spot in the garden.

In mild climates, bunching onions can be grown almost year round.  Varieties like the white Lisbon, Tokyo, Long White and Stay Green Bunching are all excellent varieties.

Peas are cool croppers as well. It’s a great idea to sow just a few every two weeks until mid-May. Peas prefer a light, loamy soil, and you’ll find fewer disease and insect problems if you take the time to keep your soil on the light side. Soil inoculants are a great idea for peas. All you do is sprinkle the dry granules of these live nitrogen-fixing bacteria over the seed before you cover them up.  You should find both improved growth and increased yields.

Radishes, too, can be planted now.  They need a well mulched soil that has very good drainage. If we don’t get lots of rain, water them to prevent them from becoming woody or pithy. To avoid maggot problems, try raking wood ashes into the seed rows.

Spinach is another good cold crop.  Believe it or not, spinach germinates best at 40 degrees Fahrenheit, so it should be quite happy to go in the ground soon.

If you’d like a headstart on other vegetables, such as early potatoes and swiss chard, choose the warmest spot in your garden, make sure the soil is well drained and use raised beds.
