If your lettuce are bolting (going to seed quickly) in Queensland, check how deep the water is penetrating into the soil. It may be drying up too quickly. Have you tried giving the plants some shade in the middle of the day? Also find out which varieties your local plant nursery is selling as seedlings. They may be the varieties that will be successful in your area.

Should we start lettuces off with plastic bottle covers in the winter here in Canberra?

Could you please let me know how much water a lettuce needs to stop it going to seed. I have planted several types over the past six months, but they either don,t grow very well or just go to seed.The soil has plenty of fertiliser and the wife turns on the micro sprinkler system each day for around 10 mins.The soil seems damp and i also use sugar cane mulch to stop the soil from drying out, I live in Queensland and the sun is on the lettuce best part of the day at the moment i have cos growing (for about six weeks) and one is just going to seed (feed that to the chooks) and the others look like they might be.The runner beans are doing very well and i have had some great spring onions as well, any help on this would be great.

Beer traps work well with snails and slugs - just cut a panel out of the side of a lidded yoghurt/margerine/sour cream plastic container, and as long as you leave an inch or so lip on the bottom of the cut out panel, you can fill the tub to the hole with beer, and put the lid on to keep the rainwater out. Check it every day or so - it can get quite full of slugs and snails so it will need to be regularly emptied and topped up - slugs and snails don't care what beer you give them - I found collecting the leftover dregs from BBQ's/parties to be the cheapest option, otherwise cheap beer is fine.

Kellie, lettuce grow best in full sun, but cope with partial shade. Just make sure they have plenty of water and never dry out, otherwise they get bitter and tough, and rapidly go to seed.

If it's snails or slugs eating the lettuce, then culling them by hand on a damp evening can eliminate the problem for a few weeks - enough to let the plants get ahead.

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!
