Why is my lettuce growing tall and thin?
ANSWER: Lettuce plants that suddenly start stretching toward the sky and growing extra tall are likely to be bolting. In the bolting stage, a plant stops focusing so much on producing foliage and starts to turn its attention toward reproduction, sending out a flower stalk that will eventually dry to release seeds.

Why are my lettuce seedlings so tall?
At the most basic level, leggy seedlings are caused by a lack of light. It could be that the window you are growing your seedlings in does not provide enough light or it could be that the lights you are using as grow lights aren’t close enough to the seedling. Either way, the seedlings will get leggy.
Why are my seedlings tall and skinny?
The most common cause of legginess is an insufficient or uneven access to light. When the light source is too dim or distant, seedlings grow quickly in height to get closer to that light. As the seedling gains height, it sacrifices in girth and strength, resulting in thin, pale, fragile, stretched-out stems.
Is it normal for lettuce seedlings to fall over?
Let’s say you’ve planted lettuce seeds in a seed starter mix. The seedlings germinate and start growing, and you start to get excited about putting them out in your garden. A few days later though, your seedlings fall over and die one by one! This is known as damping off.
What does bolting lettuce look like?
But when temperatures start to rise, lettuce plants begin flowering, or bolting. You’ll notice the main stem starting to grow tall with lots of space between the leaves. Then, the leaves turn bitter and lose their juiciness.
How do you fix bolting lettuce?
You can easily trim bolted lettuce with gardening shears or with a sharp knife, but since the lettuce will be bitter to eat, it’s best to just pull the plants out. You can then replant if it’s early enough in the season.
What do leggy plants look like?
If a plant has become ‘leggy’ it usually means it’s growing so that it has really long stems, with just a few leaves on the top. As plants grow they look for light. If they’re in a spot that’s bright enough for them they’ll be getting all the light they need and will grow normally.

Which nutrient in fertilizer makes the plant stems stronger and increases branching?
The phosphorous nutrient makes the plant stem stronger and increases its branches. Phosphate (P) promotes strong stems and bud/bloom development. Potassium/Potash (K) promotes root development and plant cell growth.
