[blogintro] => [blogs] => Array ( [0] => WP_Post Object ( [ID] => 54525 [post_author] => 4 [post_date] => 2024-01-20 10:16:19 [post_date_gmt] => 2024-01-20 10:16:19 [post_content] => Lettuces and salad leaves are incredibly satisfying to grow. Not only do they grow quickly, but they also produce an awful lot of leaves over a long period, giving you abundant salads for weeks on end from as early as late May onwards. Here are our top tips:

Plant them in rich soil with good drainage. A container with good quality compost, or a bed with added organic matter (leaf mould/well-rotted manure).
Full sun works well for most salads, but you may prefer to grow some of the oriental leaves in partial shade to prevent them from bolting: wild rocket, mizuna, mustard leaves
Slugs will be the biggest pest so do your best to keep them off your plants - beer traps and grapefruit halves work well to deter the slugs away from the leaves - and try to keep the bed free from weeds, big stones or pieces of wood so as not to provide the slugs with shelter.
Keep them well watered during dry spells to prevent them from bolting. You're aiming for soil that is consistently moist but not waterlogged. If you can see that the soil on the surface is dry, then push your finger in to check for moisture levels underneath and water accordingly.
Remove rotting outer leaves. This is really important to do as it will massively decrease slug damage (slugs like these old rotten leaves!)
Pick the outer leaves regularly, leaving a tight heart in the middle - the lettuce will keep producing more leaves that way. It is worth picking off these outer leaves even if you don't intend to eat the salad in the next few days as removing the leaves encourages the plants to stay in the process of producing leaves rather than trying to flower.

That's it really. They are such a great crop and you can plant them nice and close together, leaving around 15cm between plants, and you can also grow them between rows of other veggies like beetroots and carrots to maximise space.

I noticed that the bay tree has done some good growing and it's now shading out even more of the raised bed that runs beside it. This is no bad thing, as I'm a big fan of planting salad leaves in this part of the garden. The shade is there most of the day - the plants get the morning sun and a bit of the evening sun, but not much during the middle of the day. This is perfect for salads, as it really helps to keep the soil nice and cool, and keeps the plants leafier for longer. Those lettuces and wild rocket plants that I've planted in full sun have always, always bolted much sooner. So, if you have a bed that is in the shade for most of the day, think about using it to grow lettuces, wild rocket, mizuna and other salad leaves this summer. You might be pleasantly surprised by how well they grow.
