The Most Common Problems When Growing Lettuce (and How to Fix Them)

I love all things salad, so I raise too much lattes to keep myself in supply. Most of the time, you get a very good crop because it is such an easy plant to grow. Unfortunately, you also run against some prevalent latte problems, which can ruin your crop or at least cause you to throw it too far.

Over the years, I have learned many trade tricks to identify and deal with latte problems, which I would love to share. If you want to maximize your lettuce harvest, let’s get started.

Give the lettuce the best start

Like most plants, lettuce suffers from some problems when conditions are right, and soil nutrients are plentiful. In other words, start your lathes as strongly as possible, and you hope to have some problems.

Read our detailed post on growing lettuce first because it will give you a great start.

Environmental problems

Preventing most environmental latent problems is easy if you have a good planting practice and know what to look for.

1. Lyrics

If you have never put the bolt up to the seed, raise your hand. I am sure there are very few of us.

When lettuce grows the head of a large flower (or bolt to seed), it is usually due to heat stress. I always think that the plant knows its days are numbered, so something triggers it to produce seeds to regenerate.

Make sure that you water the soil regularly around the base of lettuce. If you live in a very sunny or hot area, provide shade, especially the hottest part of the morning and afternoon.

2. Germination

At the beginning try to start properly with your lattes. Although lettuce is reliable when it comes to germination, sometimes it does not work. It is all about temperature. About 70 ° F is correct for germination, although seeds may germinate below.

Above 80 ° F and your seeds cannot grow.

Lettuce germination depends on the correct temperature, so research which varieties grow well in your area. Some like it hot, some like it cold. Talk to your neighbors about which varieties they grow.

3. Leggie Lettuce

Okay, it may not be an official word, but you know what I mean. This is when your young lathes have a long stem and very few leaves. Depending on where they are planted, this is a fixable problem.

If lettuce ropes are still young and in the pot, they may not have enough light, so they are reaching the sun. All the energy that goes into stem development takes the energy away from the leaves. Take them to a sunnier area if you can.

If lettuce is in the garden and is leguminous, it is probably because the plants are getting too much sun or are too hot. Provide them with a little more shade as a shade cloth.

If they are already in the shade, they probably need more sun. Remember not to plant them in the same place in the next season.

4. not making any head

If you are not seeing the expected growth on your lathes, you may have many problems on your hands.

  • Ensure that the soil contains adequate nutrients. You should do this before planting seeds or transplanting. You can use a liquid fertilizer or plant food after the plant has indicated a malfunction, but remember that you should not over water.
  • Lettuce is very close. This may mean that many plants are pulling nutrients from the soil or there is not enough room for them to grow. I cut my lettuce about 10 inches apart for this reason.
  • You may have applied lettuce at the wrong time of year. Young lettuce needs to avoid the hottest part of the day. Depending on the temperature in your area, plant in late spring or late summer. In this way, you avoid the hottest part of the season when the plants are young. I have found that once lettuce starts struggling once it starts, it is difficult to grow the rest of the seasons.

Lettuce disease

Unfortunately, lettuce is one of the plants that suffers from many common diseases. Here are the ones you should definitely check out.

While lettuces are susceptible to many issues, they are generally not life-threatening for the plant.

1. Bacterial leaf spot

If you find that your lettuce starts forming brown or black spots on the leaves and then dies or they struggle, then you probably have a bacterial leaf.

This is caused by bacteria in the soil that make their way into lettuce by water splattering, improper planting techniques (making their plants properly in space) or bad luck. There is no cure after the plant becomes infected, so remove infected leaves or the entire plant to avoid further spread.

Try not to put water on the head and do not apply lettuce while planting the plant.

2. Closing

This is a problem for many plants, but the few years I get it is a problem with most lattes. First, your sprouts appear healthy, then they wilt and collapse. Do not put your lettuce in cold, highly moist soil. Make sure your soil is well drained, and do not flow into the water.

For more tips, see our guide on identifying and preventing this common fungal disease.

3. Fusarium wilt

Fusarium wilt is common. Although yellowing of lettuce can be many other things such as insufficient nutrients in the soil or too much or too little water, I think fusarium wilt is often the culprit.

It is very difficult for this fungus to control lettuce once it appears, but there are some things you can do.

First, carefully remove any infected leaves so that the fungus does not spread. If the majority of lettuce is infected, then remove the whole thing.

Next, remove some of the smaller latches in the middle of the larger one to allow more airflow and prevent the plants from touching each other.

Your last option is to use a food-friendly fungicide, but if you are like me and hate spray, this is definitely the last resort, if at all.

4. Rust

This is something that can make your latches very unpredictable. This is probably the most common lettuce disease and the biggest reason we throw them away.

Also called racet spotting, rust appears in the lettuce that has been picked up, but is also partially harvested on the lettuce. There are several types of lettuce where you can choose the leaves you need and come back for more time.

Lettuce keeps growing, and you keep picking, but over time they become less resistant to corrosion. This is because when lettuce is damaged, a chemical reaction involving ethylene gas occurs. This is why both partially harvested, and chopped lettuce receive the same corrosion damage.

I think the best solution is to pick up the leaves of your latte until it rusts. Once it appears, remove that particular lettuce and use your others. Or harvest the whole head at one time instead of the leaf from here and there.

Lathes moth

As much as we love lettuce, so do insects. In fact, sometimes I think they are just as eager for the lettuce season as I am.

1. Birds

Birds usually have a problem around ripe fruit, but there are many birds that also target the lettuce plant. If you have ever seen your lettuce plant pulled from the ground, they are not eaten, it is probably a curious bird, but they will also eat leaves and plants. If you have this problem, use a bird net.

2. Cabbage Looper

If there’s a vegetable that this insect doesn’t like, I’d love to hear it. The lattice is particularly attractive to Loafer. Read our article on how to identify and control this common garden pest.

3. Deer

I am lucky that there are no deer in my area (or ominous depending on how you look at it), but if you do, there are traps, landscaping methods and planting techniques to keep them away. Talk to your neighbors about how they stop deer or check our guide for deer-proofing our garden.

4. Earrings

Earwigs flourish in my area, so I have to deal with them for most of the year. If you wake up one morning and find that the stalk has been chewed and bitten, you are likely to have earwigs. Sometimes they do not do much damage, other times they do enough damage to sprout the sprout and die.

I prefer chemical free gardening where I can and fortunately earwigs are relatively easy to control. Take a few fullpots and fill them with newspapers. Leave them overnight and in the morning, carefully soak the newspaper in a bucket of soapy water. You should see all the earwigs that have stayed through the night.

5. rabbit

Rabbits find the lettuce very attractive and once they hide on it, they will keep returning. Use fences, nets or rabbit resistant companion plants to help prevent these fuzzy intruders.

Lettuce is one of the most common plants grown in home botanical gardens because they are very easy to produce. They grow quickly and you do not need too much to supply your needs throughout the season.
