A cool-season plant, like arugula, begins to stop producing when the weather becomes warm. When this happens, the stems begin to produce flowers. During this process, the plants become spindly and tall. Gardeners call this bolting.
Why is my arugula leggy?
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.
How do you fix leggy seedlings?
The best way to fix leggy seedlings is give them more light, ASAP! This could mean adding a supplemental grow light if you’re not using one already, upgrading to a stronger light, or lowering your current light closer to the seedlings so it is more effective.
How do I stop my plants going leggy?
There are four surefire ways to prevent your seedlings from becoming leggy and they all involve light manipulation.
- Provide direct light.
- Provide artificial light.
- Adjust supplemental light.
- Brush the seedlings gently with your hand or a ruler several times a day to strengthen the stems.
Can leggy seedlings recover?
The good news is, leggy seedlings can usually be fixed before it’s too late. I’ve transplanted hundreds of tall, floppy seedlings with success, most of which went on to recover and have normal, productive yields.
Should you cut back arugula?
Each arugula seed produces one thin stem, which leaves grow out from. You can further your crop by cutting them back — the leaves will regenerate once or twice before getting too spicy, woody, or bitter. To harvest, cut arugula at the base of each leaf off the main stem.
How do I make my plant stems stronger?
How to Make Plant Stems Stronger
- Provide the proper amount of sunlight. Without the right sunlight, your stems will become long and spindly as they try to grow upward to catch more rays.
- Don’t let plants become parched.
- Give them space.
- Take care in extreme temperatures.
- Go next-level with nitrogen.
What causes seedlings to get leggy?
The most common problem that results in leggy seedlings is insufficient light. Young, tender seedlings need adequate light to thrive. They will stretch to try to reach as much light as possible. A lot of newer gardeners will stick seedlings in front of a south-facing window assuming it provides enough light.
What is considered a leggy seedling?
‘Leggy’ seedlings typically have stretched skinny stems and look fragile. They may be bending forward rather than growing up straight with a strong stem. If your newly germinated seedlings look like this, it may be due to one of three common causes: Insufficient Light.
What does it mean when a plant gets leggy?
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.
Can you fix a leggy plant?
Yes—you can cut leggy plants back to encourage new stems to sprout, restoring your plants to lushness. Trim any exceptionally long, lanky stems, removing a third of their length and snipping just above a node (the point where leaves grow from the stem).
Can leggy seedlings be planted deeper?
Most leggy seedlings can be be fixed by transplanting them deeper into pots, planting the seedlings so the soil level comes partway up the leggy stems. This is a great way to fix leggy tomato seedlings or plants as tomatoes can form roots up the length of the stem.
What does damping off look like?
Identifying damping off symptoms
Seedling stems become water soaked and thin, almost thread like, where infected. Young leaves wilt and turn green-gray to brown. Roots are absent, stunted or have grayish-brown sunken spots. Fluffy white cobweb-like growth on infected plant parts under high humidity.
When should I pinch back seedlings?
Once seedlings are 3 or 4 inches tall with a good supply of true leaves, I pinch them back. You can use scissors or pruning shears, but thumb and forefinger work just fine. While your seedlings are growing indoors, toughen them up by man-handling them a bit. Regularly run your hand over the tops of the little plants.
When should you give up seedlings?
If there are seeds that still haven’t developed genuine leaves after a few weeks, it’s most likely time to give up on them. Most seeds will germinate within two to three weeks, but some may take about a month to get established.
How do you cut arugula so it keeps growing?
Use your hands, a pair of scissors or a serrated knife and cut the stems of the leaves about an inch from the crown or the leaf base. You can simply take a few leaves off each plant and leave the rest to continue growing for the next harvest.
What do you do with overgrown arugula?
Cooking with arugula: If arugula becomes overgrown, it is best cooked to mellow its sharp bitter flavor. I like to sauté chopped greens in olive oil and garlic until they are wilted and then use them as a bruschetta topping with grated Parmesan-Reggiano cheese.
How long do arugula plants last?
Plant in rows approximately 6 inches apart.
How –

| Seed Longevity | 5 Years |
How do I make my stems thicker?
You can get thicker stems on your plants by providing them with the required amount of sunlight, water, aeration, nitrogen, and space. The most common reason your plants don’t grow thick stems is due to a lack of sunlight. You need to learn about your plant requirements to grow them better.
What nutrient makes stems stronger?
Potassium helps plants make strong stems and keep growing fast. It’s also used to help fight disease.
What liquid will make a plant grow faster?
Water, just like sunlight, is another primary need to prepare food through photosynthesis. Deep down in the soil, water delivers nutrients up via the root system. It carries nutrients from roots to the top, much like what blood does in the human body.
