Harvest Incredible Romaine Lettuce with Organic Fertilizer

There is no organic fertilizer secret when it comes to growing romaine lettuce.  All you need to do is understand what type of environment works best for this particular crop and then create that environment within the soil.

Romaine Lettuce Preferences

In terms of the growth preferences of the romaine lettuce plant, you’ll find that it similar to the preferences of other types of lettuce. Lettuce grows best in an environment that is high in nitrogen. Using a nitrogen based organic fertilizer is the ideal material for increasing romaine lettuce growth.

Blood Meal

Blood meal is the strongest option when it comes to an organic fertilizer with nitrogen content.  It also has a high iron content, making it doubly valuable for the growing of healthy lettuce plants.  


One of the benefits blood meal as the choice for organic fertilizer is that it does have high amounts of nitrogen relative to its size and weight.  You don’t need to create any synergies with other fertilizer types, because you’ll get everything you need right away from the use of the blood meal fertilizer.

That being said, the best choice for creating a synergy, should you still want to do it, is seaweed fertilizer.  Seaweed will increase the already high iron content in the blood meal, allowing your romaine lettuce crop to grow larger.  

Even though seaweed will create that synergy, it is not necessary to the successful growth of romaine lettuce. Bone meal provides the high levels of nitrogen as well as a significant amount of iron by itself.


Blood meal fertilizer saturates the soil with nitrogen particles if you give it a chance to enrich the land.  For that reason, you should decide where you are going to plant the lettuce about two weeks in advance.  It becomes more effective if you allow for two weeks for the bone meal to mix completely with the dirt and be absorbed.

After two weeks of mixing with other soil and nourishing the ground, lettuce plants will have developed its folk buds to have a much better early growth period.

The harvest of romaine lettuce can also be increased if you add a seaweed fertilizer. Seaweed adds a strong dose of iron to the soil, which helps strengthen the romaine lettuce. You will notice a difference in the size of the romaine leaves and the strength of the attachment.
