Lettuce offer a range of shapes, sizes and colours but they are all easy to grow.

Choose a variety marked on the seed packet as suitable for the time of year as some do badly in the very hot months.

Try to provide some shade to prevent them 'bolting' to flower and seed in the hottest months.

Sow in rows and use thinnings as small salad greens.

Ideal crop for succession planting.

Lettuce are shallow rooted so water daily in hot or dry weather to prevent bitter flavour. and bolting.

When they have 6-8 new leaves. Keep them protected from the sun for a couple of days. Plant in the late afternoon.

Will it be to late to sow Lettuce seed in Johannesburg region in February. Have a well protected area from early cold and can provide sufficient water when rainfall reduces from March.

When you cut lettuce dry it out before putting in a bag and into the fridge. A spinning colander is best.

My lettuce are growing well except The round head is not forming. I have taken a piece of cotton and tied all the outer leaves lightly together and now I see the inside is forming nicely. What am I doing wrong.

Lettuce gets bitter if it's too hot and/or when it bolts. Lettuce is ideal is cool temps, and if grown in hot weather does better in the shade or at least partial shade. Full sun in cool weather is fine. Also, too little water causes butter lettuce. Make sure you are either harvesting the plant all at once, or you pick he outer leaves on a consistent schedule. Picking leaves inconsistently can also cause lettuce to bolt.
