Harvesting lettuce for its outer leaves not only allows you to harvest sooner but also extends the season of the plant. If you pick the outer leaves off of a mature or almost mature lettuce plant, the inner crown will continue to grow more. After it flowers it will produce seeds for you to collect. This is the last harvest of leaves, however. Heading lettuces should mature between days.

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.

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?
