Make sure that you don’t damage the other plants near the lettuce plants and also parts of the lettuce plants. You need to try this method until the aphids completely vanish.

Also avoid planting those plants that can attract aphids near and your lettuce plants also suffer like Brussels sprouts, corn, potatoes, etc. Companion plants are seen to be highly effective if you make the right choice. You will start to see the change that the aphids will stay away from the lettuce leaves.

The moist soil if watered will become soggy and the eaves will drop becoming more suitable for the aphids to attack. Aphids attack the soft leaves and the young ones too—water lettuce one to two times a week about one inch deep

8. Avoid overfertilizing 

The overfertilized lettuce plants are again stressed. aphids attack the stressed plants facing some kind of environment or other stress. The fertilizing of soil enhances the production and new growth in the plant, the plant gets less hardy, and new leaves appear.

Over-fertilizing will enhance this process. The aphids will quickly attack the young tender parts of the plants. You don’t want them to fertilize much only during the early growth times but not later. Keep it to a minimum afterward.

Don’t let the weeds grow near the plants, as the weeds can be the entry spot of the aphids. Weeds invite the aphids and easy targets of aphids.
