Tips for Growing Lettuce In The Garden

There’s nothing better than a salad made with fresh lettuce from the garden. Adding lettuce to your garden can be a welcome addition. Not only is healthy and tasty to eat but it needs very little space to grow. But there are some guidelines you should know before planting lettuce.

To grow lettuce or any other vegetable, you need to have good soil. For lettuce, keep the nitrogen level high by using 30-10-10 NPK (nitrogen, phosphorus, potassium) fertilizer. This will provide the lettuce with the nutrition it needs to produce healthy leaves.

Plant the seeds about 1/8-3/8 inch deep, separated by 6-12 inches (2-3.5 m) from the next plant. Romaine does fine at the smaller spacing, but crisp lettuce needs more room. If you plant in rows, keep the rows separated by about 20 inches (6m). Keep in mind that seeds shouldn’t be planted too early, since they’re subject to cold damage.

Keeping the soil moist but not soaked is good. Lettuce doesn’t have very deep roots, so it needs to find moisture near the surface. Still, try to keep the water off the leaves and onto the soil, except for the occasional washing. Wet leaves encourages disease, especially when they’re moist during nighttime temperatures.

Since their roots aren’t very deep you’ll also need to be diligent about weeding around lettuce plants. Many grasses and other plants can compete well because their roots go down to deeper soil. Infrequent but deep watering, letting the top layers dry out, will give most an advantage. But lettuce doesn’t have that advantage, so you’ll need to help them.

Like most vegetables, lettuce plants also have problems with diseases and pests. In their case, the variety is quite large. Many insects find the leaves irresistible and the folds offer many places for fungi to grow.

Aphids, flea beetles and leafhoppers are common problems. Slugs are even more so. Cutworms are often seen. Washing with a high pressure hose can help temporarily, but be sure to do it early to give the leaves time to dry before nightfall. A good insecticide lightly applied will keep them under control for the long term.

Anthracnose (Microdochium panattonianum) is a common fungal disease. It can stay alive in unplanted soil for many years, so don’t assume you’re safe because your garden is new. Bottom rot (Rhizoctonia solani) is another common fungus. It occurs usually in soil that drains poorly. Keeping the foliage dry and planting in good soil will help to reduce the odds of being infected.

Another common problem with lettuce is bolting. Bolting is not a disease or pest but occurs when the plant goes to seed and the leaves stop growing. Bolting happens when the temperatures are consistently too high. To prevent this from happening, plant lettuce in shaded area or plant next to a shading crop such as corn.

With the proper preparation, planting technique and care you can have lettuce several times during a growing season.

Tips For Planning A Successful Vegetable Garden

Growing vegetables is much easier than many other plants. With just a minimum of good planning, proper planting and a little bit of care you’ll have a bounty of tasty, natural things to eat.

But before you sow a seed, think.

Climate

Consider your climate first and foremost. Know the conditions necessary for the type of vegetables you plant, so be sure to understand how these plants will be influenced by tropical, temperate, or cold weather. Within these broad categories there are several sub-types. The range of climates in the U.S., for example, runs across a dozen zones. You should not plant tomatoes – a heat-loving vegetable – when you can anticipate a frost after winter’s end.

On the other hand, beans, broccoli, cauliflower, onions and more grow well when in cooler climates. They like 50F-68F (10C-20C) weather and will tolerate frost fairly well. Cabbage, carrots, lettuce and others will prefer slightly warmer temperatures, about 60F-75F (15C-25C). Tomatoes, corn, eggplant and potatoes prefer it hot.

Your garden can get too much wind. Providing a wind break might be a good idea. Wind can dry the soil and break tall plants. Cold winds, in particular, tend to stunt plant growth. They remove the heat provided by the sun. A garden lattice or an appropriately designed fence can solve the problem.

Location

Next, consider the total area and location of your planned vegetable garden. A family of four might do well with a 100 square meters, but that’s far more than a novice gardener will want to care for at first. Beyond size, think of the specific needs and nature of each plant. Corn grows tall, so it will produce shade. But you don’t want that shade to block sun desired by those tomatoes.

When considering the location, think about what you might have to do to protect the vegetable plants from excessive shade and wind. Some places are shaded naturally, and perhaps too much so.

Vegetables like sunlight. At least five hours per day is needed by most. You’ll be able to tell they aren’t getting enough if your vegetables are far below average size, if the leaves are wimpy looking and by other signs. Plant the taller vegetables, like corn, to the north of the shorter ones. Plants low to the ground, like lettuce, need to be nearer the south edge.

Water

Give your vegetables plenty of water. Unlike herbs and some other plants, vegetables need lots of water to grow. They’ll need good drainage in sandy loam in order to avoid root rot. But beyond that, the more water, the better. Watering the base and roots is more important than keeping the leaves wet. A drip system can provide the perfect solution here.

Be prepared to do what the pros do and rotate your crops from year to year. Different plants take different things from the soil in varying quantities. Some of that can be replaced with compost, fertilizer and other soil treatments. But help out by changing your design once in a while.
