If you’ve bought a bag of salad lately, you’ve probably seen the headlines. Another lettuce recall is making its way through grocery stores and restaurants this summer, leaving home cooks wondering whether it’s safe to eat what’s sitting in the crisper drawer.
What’s Behind the Latest Lettuce Recall
This time, the concern is Cyclospora, a microscopic parasite that causes an intestinal illness called cyclosporiasis. The investigation is still ongoing, so the full scope of the outbreak may continue to change.
It’s the kind of food-safety story that keeps repeating itself, only with a different pathogen, crop or supply chain each time.
Grow Your Own Lettuce Instead
Here’s the good news: growing your own lettuce gives you far more control over how it is grown, harvested and handled. You know where it came from, what was used on it and how long it has been sitting in the refrigerator.
And lucky for us here in North Texas, lettuce is one of the easiest vegetables to grow at home. You just have to plant it at the right time. Let’s get into how.
When to Plant Lettuce in North Texas
Lettuce is a cool season crop that requires mild temperatures in order to thrive. Because our summers are too hot to grow lettuce properly, we need to grow lettuce during the cooler seasons of fall, winter, and spring.
For a spring crop, you can start lettuce seeds indoors during the month of January, or you can plant seeds directly anytime between February 1 and Mar 15. Planting later than mid-March puts your lettuce at risk from rising temperatures.
For a fall and winter crop, start lettuce indoors or sow directly into the garden between September 1 through October 15. (As soil temperatures decrease, germination rates will slow.)
To ensure a continuous supply of lettuce–not just one big harvest–we can sow lettuce in intervals. This is called succession planting.
Sow baby leaf lettuce (indoors or out) every 7 days during the planting window, and sow head lettuce every 10 days. Be sure to leave room for future successions when planting.
Best Lettuce Varieties for Our Heat and Humidity
When shopping for lettuce seeds, look for varieties described as “early to mature” and “heat tolerant”. These are qualities that make lettuce easier to grow here in North Texas. We need lettuce that is going to grow and mature before the heat arrives, but we also need varieties that will tolerant said heat better than others.
Certain types of lettuces are better for growing in North Texas than others. Crisphead types like iceberg need long stretches of cool, even temperatures to form a tight head, which makes them better for growing during winter here.
Loose-leaf varieties like Black-Seeded Simpson and Bibb-style butterheads are far more forgiving and can be grown easily during fall and spring. They mature quickly and hold up better once the heat creeps in.
Romaine falls somewhere in the middle. Heat-tolerant varieties like Jericho or Sparx will get you a lot further than a standard romaine before it bolts.
My personal favorite lettuces are Marvel of Four Seasons, Volcana Bibb, Ice Queen, and any of the Salanova varieties available from Johnny’s Seeds.
For harvesting as baby lettuce, look for mixes like Allstar Gourmet Lettuce Mix from Johnny’s Seeds or the Cut and Come Again mix from Renee’s Garden Seeds. (Renee’s carries a wide variety of mixes.)
Prepping Your Soil (or Container) for Lettuce
Lettuce needs fertile soil that is well-draining. Most of our soil here in North Texas is heavy clay which holds on to too much water. Whether you have heavy clay soil or sandy soil, your soil will need amending before you plant. Mix high-quality compost from a nursery into your soil before planting to improve soil texture, add nutrients, and balance pH levels.
If growing lettuce in containers, fill your containers with a high-quality potting soil from a reputable independent nursery. The potting soils at home improvement stores dry out too quickly.
Fill raised beds with a bulk planting mix (not the raised bed mixes at home improvement stores) from a landscape materials supplier, or make your own raised bed mix with 75% compost and 25% topsoil.
Planting and Spacing Your Lettuce
No matter which vegetables you are growing, it is very important to space the plants correctly. If you plant vegetables like lettuce too close together, the plants will compete with each other for light, nutrients and water. This leads to weak, unhealthy plants that won’t thrive in your garden.
You can find spacing information on the seed packet. This is how far apart to sow your seeds or plant seedlings. Always follow planting directions on seed packets for best results. My favorite seed companies like Johnny’s, Renee’s, and
Watering and Care Through the Season
Lettuce requires consistent soil moisture to grow well, but be very careful not to overwater. Soggy soil creates conditions in which diseases and pests thrive.
After sowing seeds, keep soil moist (like a wrung out sponge) at all times until germination occurs. If rain is scarce, water young seedlings or new transplants daily for about a week, then water only when the soil needs it. To tell if your soil needs
When you water, water deeply enough so that water reaches six inches down into the soil. It is much better to water your soil deeply yet infrequently versus frequent, shallow waterings.
Beating the Bolt: Keeping Lettuce Alive in North Texas Heat
When temperatures are too high, lettuce responds by sending up a flower stalk. This is called bolting. Once lettuce bolts, the leaves turn bitter fast, and there’s no reversing it.
To prevent bolting, only grow lettuce during cooler seasons. Avoid growing lettuce during summer.
Bolting can be delayed or prevented by protecting lettuce with
Harvesting Your Lettuce for Continuous Growth
With loose-leaf and Bibb varieties, pick the outer leaves first and leave the center intact. The plant will keep producing new leaves from the middle, giving you several harvests from one planting.
For baby leaf lettuce, harvest once leaves are two to three inches long. Use scissors to shear the whole planting about an inch above the soil, and allow to regrow for one or two more cuttings.
Harvest lettuce in the morning, when leaves are crisp and less bitter. Check plants every few days once they’re established, because regular picking encourages more growth. For head-forming types like romaine, you only get one harvest, so cut the whole head once it is full-sized.
Common Lettuce Pests and Problems to Watch For
The most common lettuce pests in North Texas are aphids, slugs, snails, caterpillars and leaf miners. Check the undersides of leaves regularly and remove pests as soon as you spot them.
Aphids can usually be knocked off with a strong stream of water, while caterpillars can be picked off by hand or treated with Bt (Bacillus thuringiensis) when necessary. Slugs and snails are more common in damp areas (don’t overwater) and can be trapped or removed at night.
Lettuce can also develop fungal diseases when plants are overcrowded, soil remains soggy or leaves stay wet for long periods. Prevent problems by spacing plants correctly, using drip irrigation, and harvesting damaged or aging leaves promptly.
