How to Grow Jericho Romaine Lettuce

Now that you have the rundown on all things Jericho Romaine Lettuce, it’s time to learn the basics of how to grow them.

Without further ado, let’s get into it.


It’s best to plant the lettuce when spring begins. This is because Jericho Romaine Lettuce really needs all the sunlight it can get.

Directly sow the seeds a quarter of an inch deep. Sow them 2 inches apart, with each row being 6-8 inches apart.

Since this lettuce is used in hot and dry climates, you must pay attention to how you water this plant. Keep the lettuce plants moist, and be careful how you tend to them, as they are quite delicate while growing.

When the seedlings sprout, make sure to thin out the extra seedlings that are not as strong. This is essential to the survival of your plants because as they grow, they’ll require more nutrition, and they can’t be fighting amongst each other for it.

Growing Jericho Romaine Lettuce

Once you’ve thinned out the seedlings, leave the remaining plants 12 inches apart from one another to give them room to grow.

The plant takes 1 to 2 weeks to germinate, and they take 60-75 days to reach full maturity.


Harvesting your Jericho Romaine Lettuce is a simple task. Cut off the mature heads when they feel firm and filled out with leaves.

You can compost or throw away the lettuce heads you don’t like and the ones that have over-matured as well.

Diseases and Pests

Diseases and pests are always a hassle to deal with. Here is what you need to look out for while you grow your lettuce.


Jericho Romaine Lettuce is thankfully very resistant to downy mildew, powdery mildew, and tip burn. It is particularly almost immune to tip burn due to its adaptation to warm weather.

Jericho Romaine is susceptible to lettuce mosaic virus, bottom rot, drop, and damping-off.

Releasing ladybugs into your gardens can help prevent the spread of the lettuce mosaic virus because they eat what are known as aphids, which spread the lettuce mosaic virus.


Birds and rodents are the primary pests to look out for. They can be prevented through nets above the planting site and mouse traps respectively. Owning cats is also a great way of getting rid of rodents.

Bugs are perhaps the bain of every gardener’s existence. Using pesticides that are safe for your plants should do the trick to get rid of them.

Cutworm Caterpillar

Cutworms are also a big problem when it comes to growing lettuce. These are quite annoying to deal with, as the only way to handle them is to go out and pick them off one by one with gloves and a flashlight at night.

When you have all the cutworms in your possession, you must dunk them in soapy water. Do this for a few nights, and the problem should be dealt with.
