Head Lettuce Problems: What To Do For No Head On Lettuce Plants?

The following are some of the reasons why your head lettuce plants will not produce heads at all. If any of these reasons apply to you, then it means that there is something wrong with your plant or your soil. You have to do something about it!

1) Watering Too Much : Some of the most common causes for no heads are too much water or too little water.

Too much water may cause the roots to rot or die. Soil problems may result in lack of nutrients.

When the root system dies off, the plant won’t be able to get enough nutrition from its own leaves and flowers.

2) Nutrient Deficiencies : If your plants don’t receive adequate amounts of nutrients, they will not grow well either.

Many times, nutrient deficiencies can be caused by poor drainage or improper watering methods.

3) Temperature Changes : Hot temperatures can kill lettuce plants.

They need cool temperatures to thrive. If your plants are grown under hot conditions, they will become stunted and eventually die.

4) Disease : A few diseases can affect your lettuce plants causing them to wilt and turn brown.

These include powdery mildew, leaf spot, stem curl, spider mite infestation and many others.

5) Lack of Sunlight : Lettuce plants need a minimum of six hours of sunlight in order to grow properly.

If you’re having a hard time getting your plants to grow, you may need to move them to a sunnier spot.

6) Too Much or Too Little Water : Lettuce needs consistent moisture, but not too much.

If you water them too much, you could end up with root rot or fungus on the leaves. If you don’t water them enough, they will wilt and eventually die.

7) Poor Soil : Using poor soil or compost when growing your plants will result in plants that won’t grow well at all.

The problem with using some types of soil is that they don’t contain the nutrients that your plants need to thrive. Also, some soil may drain too quickly or not quickly enough.

8) Genetics : Some varieties of lettuce are just hard to grow indoors.

If you’re having a hard time getting your plants to grow, you may need to start over with a different variety of seeds.

How to Fix the Problems

Now that you know what some of the problems are, you probably want to know how you can fix them, right?

It’s actually easier than you think. First of all, make sure that you know why the problems exist in the first place. If you don’t know why, then you won’t be able to fix them. Second of all, you should start over with a clean slate. This means getting new seeds or new plants and growing them in a separate place from where the old ones were.

If you’re having problems with your soil, make sure to add more compost or buy some fertilizer at your local garden center. If you don’t want to spend any money, then you can also make your own compost at home.

Your plants will thrive much better if you use compost instead of normal soil.

And as always, if you’re having a hard time with your watering schedule, get a moisture meter so you can keep track of how wet the soil is. Just stick it into the soil to see if it needs water.

Don’t water too much and don’t water too little!


Now that you know what the problems are for growing lettuce indoors, you can take steps to correct them. Lettuce is a great thing to grow because it doesn’t require too much maintenance.
