Hi again What's the best way to grow lettuce? Plant the actual seeds or grow the seeds in cotton wool until seedlings then transfer? :)

Bill: Lettuce going straight to seed usually happens when it's too hot or dry (cabbage & silver beet tend too as well). As you water daily I am guessing that the lettuce are getting too much sun, have you tried shading them from afternoon sun? I have some lettuce growing in the shade of my tomato forest (planted a little close together this year). The lettuce get maybe 2 hours direct sun first thing, then shaded for the rest of the day, and they are doing really well.

I have tried 3 or 4 different types of lettuce seedlings and also grown them from seed - all have the same problem going straight to seed without hearting, they are watered by bore sprinkler every day and in full sun. Any ideas?

Georgie, Sounds like your lettuce maybe getting too much sun. I grow mine in filtered sun/semi shade in summer and they cope much better.

I'm having trouble with birds shredding young lettuce plants before they're big enough to eat.Thought it could be the hotter summer and birds are thirsty,but they seem to prefer my lettuces better than water bowl.Any suggestions?(apart from covering the plants) Thanks, Ann

Try hanging old CD's up on string. I have heard that the birds don't like the flashing the CD's give off in the sun. Hope this helps.

Believe it or not, try a small scarecrow in the garden. We have two gardens, each with similar plantings. In one the lettuces have been shredded but the one with the scarecrow is perfect....

Gerri...ive heard that lettuce needs to be grown fast for it to be sweet. Lots of nitrogen rich organic liquid fertiliser.

To increase the levels of Molybdenum (Mo, also called Molly) in your soils -- wood ash (from a fireplace, firepit, or barbeque) can be incorporated into the soil. Alternatively, Banana peels are an excellent source of Moly. Animal manure tends to (grass/grain/vegetable feeders) tend to have a decent amount of Moly in their manure. If all of these are out of reach, perhaps try incorporating wood chips/bark mulch in your garden. You can make bark chip paths, use the paths, then the following year when the chips are broken down mix them into the soil. OR -- just mix the wood chips (bark, mulch, whatever) directly into the soil. As the wood is breaking down it takes a lot of nitrogen. I would expect to find Moly in leaf mulch - but have not found any reliable sources that have stated this as a fact. If you choose to use chemical forms of Moly remember that this is a TRACE element - VERY little is needed and over application can result in a OTHER problems. Staying organic almost guarantees you will not over apply. If you live in an area where wood burning stoves and fireplaces where common for heating (pre- electric fireplaces and stoves) - and you know people old enough to have been around when wood ash was common in the garden (there was no place else to put it) - they can tell you how amazing the gardens where back then.
