Seed more lettuce. But how do i make out 'before maturity' stage? You can start harvesting baby greens when they are 4 to 6 inches in height about days from planting. When you top harvesting is a judgemental call. The leaves will taste bitter and the plant will look weak and no longer be producing leaves.
How you harvest is up to you. You can use scissors and cut your lettuce off at the soil. And then the plants will produce new leaves from the base and can be harvested a seconod time in 3 to 4 weeks. Or you can plant so that each head is 4 to 6 inches apart and harvest outer leaves or entire plants. Lettuce is healthier than you realize. It also provides Vitamin-A and Vitamin-K. It also has small amount of many other healthy nutrients. It is low in fiber and it has high water content.
When harvesting outer lettuce leaves, is there a general rule of thumb regarding the amount that can be taken and how frequently? Hope my question makes sense. You can selectively harvest outer lettuce leaves before the plant reaches full maturity or as soon as the outer leaves are 2- to 3-inches tall. You can cut or gently break off leaves as needed without harvesting the entire plant. Or, if the plant has reached the desired maturity, the entire plant can be pulled.
I'm in a middle of a plight. I'm leading a research work in order to investigate the transmission of hereditary information from the lettucce. In order to do so, I need to isolate one factor, such as light , salt or humidity; modify it according to the amount and analyze the difference between two generations. It's been troublesome lately, and I was wondering if you would be so kind to help me. I am harvesting them outwards, where sun light is always upon them.
I need you to tell me how much amount of water a lettuce can withstand without dying, the minimum, the common and the utmost. I would also appreciate whether you would be able to do the same with salt. In our country, we are facing problems about harvesting Iceberg Lettuce because of uncertain weather. Base on your experience at Farm, what is the best time to harvest this type of Lettuce? Some say that the harvest must be done before sunrise. Kindly need your information. Raised vegetable beds Zone 5.
My wife says watering in heat of day full sun bad for vegetable leaves if water covers the leaves. I use a medium spray garden hose. Drip irrigation not an option - at least this year. On some smaller plants carrots and narrow leafed lettuce the plants do tend to mat down - but spring back as sun helps evaporate water.
Should I switch to watering can and avoid watering plants directly? I did read in comments that keeping soil moist is good - at least for lettuce - I may need to water twice a day?
Thank you. Lettuce is delicious and does help with stress! I point out that natural rainfall is indiscriminate! Just look at it. If the leaves are wilting, sprinkle them anytime—even in the heat of the day—to cool them off and slow down the transpiration rate. So, not necessarily twice per day. Have you tried a hose without the spray nozzle: laying it down on the soil near the plants and soaking only the ground that way? Yes, you would move it as necessary to water all of the plants.
Reduce the water volume so you do not make divets in the soil. And have you tried row cover? Covering the plants with it reduces soil evaporation and keeps the plants from frying, wet or dry, in the heat of the day.
I live in a Senior Community that has raised 4' beds for residents to plant small gardens. They are filled with fill dirt, which means lots of rocks we're in Tennessee , but I see no weeds. Should I put down a weed barrier over the dirt that is in there, then put new garden soil mixed with compost on top?
Or mix the new garden soil and compost with the existing dirt, then put the weed barrier down before planting? Or do I even need wee barrier if there's no weeds in there now? Thanks so much for your help. Hi, Fran. You could till the soil and get rid of as many rocks as possible or cover with weed barrier or even damp newspaper and then add garden soil and compost. Weeds find a way, they are sneaky little buggers, so we recommend protecting your plants even if there are no weeds present at the moment.
Good luck! I planted my lettuce, spinach, beets and rutabaga in my raised garden bed few days ago. We received low temps and light snow yesterday. Will my seeds still germinate if the temps rise, or will I have to replant? If they germinate and sprout and we have another light snowfall or low temps, can I cover them to protect them, or will they die?
The instructions said to plant them in early spring as soon as the soil could be worked. Did I plant them too soon? I live in zone 9a. Would you recommend drip or sprinkler irrigation for red leaf romaine, butter crunch, spinach etc for late October planting from plants already sprouted I picked up in flats from the garden center?
Therefore, drip irrigation would be the wiser choice, as it will give you consistently moistened soil. Iceberg lettuce is a variety of cabbage, which needs cool temperatures and plenty of water.
It should be grown early in spring or in early fall, and does not do well in the summer heat. Mulch around the base of each cabbage head to retain moisture and keep the roots cool. We hope this helps! I have a friend who needs about 5 kilos of butterhead lettuce. It's pretty hard to find them in Luzon.
Do you know where they are sold? Its important for the soil texture and roots navigation. Use any vegetation and lay it on the ground. The amount of debris should be sizeable. At least between one tonne and five is pretty fine. The pressure out of compression generates a lot of heat. Hello my name is Karime Gonzalez. I'm carrying out a science project in which I choose to harvest lettuce.
The project is basically to make something to help the community. So if you could tell me if you know how to make organic fertilizers I would really thank you. With many varieties of lettuce, especially loose-left lettuce, you can keep harvesting from the plant. If the weather stays cool, you can keep harvesting from the plant several times or more. Lettuce is bolting if it forms a central stalk that eventually rises high above the base leaves. This seed stalk which has leaves along its stem will form flowers toward the top and eventually seeds.
During this time, the lettuce leaves develop a bitter flavor. Hi my lettuce has been growing well for the season but now it is not producing any more lettuce and I have been told that it is doing something called going to seed but I really don't know. I was wondering if I could still do anything with them or if they were totally done.
Leaf lettuce can stop growing when it is preparing to bolt go to seed. With five main types — red-leaf, green-leaf, stalk, heading lettuces and romaine — and hundreds of varieties, lettuce lends itself well to some interesting uses.
For instance, chunks of fibrous stalk lettuce, also referred to as asparagus lettuce or cultuce, go great in stews and stir fries, and romaine -- although best known for the Caesar salad — has a plump, white rib in the center of each leaf that begs you for a few seconds on the grill, and rewards your effort with a delicate smoky flavor.
Although you determine the ripeness of lettuce mainly with your eyes and hands, checking your calendar for when you planted lets you know when to start looking to harvest.
Examine green- and red-leaf lettuce varieties for ripeness about 50 to 60 days after planting, or when the outer leaves grow to between 4 and 5 inches tall. Ripe leaf lettuce develops rich-colored, well-ruffled and deeply lobed leaves upon maturity.
However, you also can harvest leaf lettuce when the outer leaves are only a couple inches tall for greens sometimes referred to as baby lettuce leaves. Snip the outer leaves from leaf lettuce to about 2 inches above ground level using gardening scissors when ripe.
Allow the inner leaves to mature and harvest again. Examine iceberg or butterhead lettuce varieties for ripeness between 60 and 70 days after planting, depending on the cultivar, before any of the plants send up a seed stalk. Pull the loose leaves away from the base of a few various heads.
Grab each head in both hands and squeeze it gently. Ripe head lettuce has a firm, full feeling in your hands, indicating it has developed completely in the center and has little space between the layers.
The outer leaves should wrap tightly around the head.
