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

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....

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.

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 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?

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.

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? :)

Hi, My lettuce seem not be hearting, but growing straight up like little trees. Is this right? First time vegie gardener!

When the root temperature of lettuce gets to 23 degrees the plant bolts - goes to seed. The plant does this as a survival mechanism. Something like, "Ouch, it's too hot! Quick, produce seeds before I die so my offspring will have a chance to grow in the future". That's lettuce. True also of coriander. Mulching the ground will help. Shadecloth will help. Taller/established plants nearby casting shadow is arguably best - see permaculture for design tips.

You can't grow lettuce in May, surely it is too cold...
