claudie, i plant lettuce seed directly into the ground, (quite shallow) with a scattering of seed raising mix below and above them. Just thin them out when they've grown a little. I plant them quite close because we eat mostly young leaves (continuous picking). I plant in dappled light, under trees........they are surviving frosts at the moment. Have fun planting!

Claudie: I find a shallow tray works best (go to the supermarket and get a packet of 4 finger buns the plastic container is ideal) fill with soil, moisten, put the tray back together, put on the HWS check after 3 days. plant out when the second set of leaves appear. Keep moist!! Michelle: Sounds like your lettuce is going to seed. This happens when it is too hot and/or too dry. Jarred: choose cold climate veges! probably too late now for most things in canberra. You could try some peas and lettuce, get some frost blanket/fleece to put over them if it is going to frost o/nite.

I use the root part that often comes with supermarket lettuces. After we've eaten the bought lettuce, I just bung the root (with a leaf or two remaining) into the soil. Some don't take but most do. Free lettuces!

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.

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.

Hi Russ - it's all about feeing the soil and creating humus, as small boxes provide limited access to nutrients (even using good quality potting mix) because they get eaten up so quickly by the hungry plants. a worm farm or compost are perfect so you can feed the soil regularly each week as natural fertiliser. also - are the boxes draining from the bottom? when you water, the nutrients run straight out the bottom and the plants cant access them. You can build really simple self watering containers in old broccoli boxes... punch a few holes along a horizontal line, about 1/4 from the bottom of the box. then fill to this line with pebbles or gravel - this creates a water table where water will sit and if too much water is added it spills out through the holes. put the soil on top with lots of compost and worm castings, plant your vegies, and then mulch on top. this system allows the roots to reach water at the bottom, but stops the soil from being water-logged. it also allows you to mulch and build humus within the soil without draining it all away. I even water at the edges of the box so that the water goes straight to the water area without disturbing the humus to stop any nutrients draining away. i hope this makes sense! I read Jackie French's Soil Food Web book which was also really helpful. good luck!
