Here’s what you should know to get started:

Growing Conditions for Papalo Herb

When looking for an ideal growing location, pick a place with plenty of warmth. The papalo herb is native to Mexico, so it loves to grow in a warmer climate.

You should select a growing space that has enough room for this plant as it becomes as large as 5 feet tall when fully grown.

Plus, the plant needs a growing location with full sunlight. It can grow in partial sunlight as well. However, the more heat and light this plant is supplied, the better flavor you should receive from your harvest and the better growth you should see in your plants.

You may also grow papalo in a container. Select a planter that’s a foot deep to ensure the roots have plenty of room to grow.

Papalo must be grown in soil that’s well-draining as it does not enjoy being left in oversaturated situations.

This herb also does best when grown in planting zones four through nine. Even in these areas, this herb is considered an annual.

Yet, it self-sows very easily, so don’t be surprised if you have volunteer seeds emerge the next growing season.

Finally, you should be aware that there are two main varieties of papalo. The first option is broadleaf. This one is most commonly grown.

The second option is narrowleaf papalo. This option isn’t grown as much due to its robust flavor. Some people view it as overpowering.

Ensure you pick the variety of papalo that’s right for you and a growing location which supports this plant to get your growing season started on the right foot.

How to Plant Papalo Herb

Most people grow papalo from seed. It’s up to you whether you start the seeds indoors to get a jump on the growing season or if you sow them directly.

If you start your seeds indoors, be sure to do so 6 weeks prior to the final spring frost. Fill a growing tray with well-draining, nutritious soil.

Place two seeds per cell of the tray as a germination insurance policy. Should both seeds germinate, pick the strongest plant and cut the weaker plant off at soil level with clean scissors.

Cover the seeds lightly and mist them with a spray bottle of water. Keep the seeds in a warm growing location.

It should take around two to three weeks for the seeds to sprout. Once they do, continue to keep the soil evenly damp and move the growing tray to a location with bright, indirect light.

When your seeds are approximately a half-foot tall, and the soil is warm, harden your seedlings off and plant them outdoors.

Ideal soil temperatures for these plants are 75-degrees Fahrenheit or higher.

The next option for growing papalo is to sow the seeds directly. Prepare the soil by tilling it. Sprinkle the seeds over the soil and lightly cover them with dirt.

Keep the soil evenly damp without oversaturating the area. Too much moisture could lead to your seeds rotting. Wait until the seeds germinate, then thin them to where there’s at least one foot of space between each plant.

Continue to water the plants and provide care as they grow. Planting papalo isn’t difficult. It’s a matter of deciding the right time and method to start your plants and providing adequate care to these young crops.

Caring for Papalo Herb

You have your papalo plants in your garden location. Now what should you do for them?

The answer is simple: provide adequate care to encourage abundant growth. How do you provide this care to your herbs? By following these few basic tips.

First, you should water your papalo herbs. Water the plants deeply to ensure you don’t overwater them and also to encourage a deeper root system. Deeper roots typically lead to a healthier plant.

Papalo is a drought-tolerant plant once established, but you should still provide a deep watering session to the plant as it’s needed and when possible.

Don’t add more water without checking the soil. Insert your finger into the dirt next to the plant. When it’s dry to your second knuckle, you may water the plant deeply again.

The next thing you should do for your papalo herb is pinch the tops of the plant. This encourages the plants to grow bushier.

If you don’t pinch the tops, there’s a good chance the plant will become droopy.

There are two things you should avoid doing to provide care to this plant. The first is avoiding overwatering. We discussed watering your plants deeply and this is a valid reason to do so.

If you overwater your herbs, this can lead to rot and also introduce fungal issues to your plants. You also shouldn’t fertilize papalo herbs. They don’t need it.

Should your plant look like it’s struggling, you can add a side dressing of compost, but that’s all the plants should need to thrive.

By providing adequate care to your herbs, they should produce beautifully throughout the growing season.

Garden Pests and Diseases Which Impact Papalo Herb

Many plants face threats when growing in any location. Fortunately, the papalo herb is one of the rare cases where they have no common threats of pests and diseases in the garden.

However, remain alert. Should you notice an issue with pests, be sure to treat the plants immediately to avoid widespread damage.

The likelihood of developing a pest issue is still rare due to this herb being a natural repellent of many insects.

Also, be sure to plant in an area with plenty of sunlight and well-draining soil. Fungal disease loves to grow in cold, wet areas. By growing your papalo herb in opposite conditions, you’re taking steps to avoid this issue.

However, this is only a suggestion as this plant has no known issues with disease.

How to Harvest Papalo Herb

Papalo is generally harvested and used fresh. It’s best to harvest the crop when it’s young to enjoy a milder flavor.

The flavor profile becomes more pungent the older the plant gets. Harvest the herb by snipping the foliage away from the plant on an as-needed basis.

You may wrap the harvest in a damp paper towel and store it in your refrigerator until you’re ready to use it. Storing the herbs in a small vase of water is another way to keep them fresh.

Either storage option should help keep the herbs fresh for up to three days.

This is the most common way to harvest papalo. Make sure to keep an eye on your plants, so you can enjoy the harvest in its ideal state. Papalo should be ready to harvest in approximately 6 weeks after the time of planting.

You now know how to grow papalo. It isn’t an overly complicated plant to grow. Provide a little bit of care, observe your plants, and pick the best growing method for yourself.

Once you have these things in mind, you should be able to start this plant off on the right foot and work towards a delicious harvest in the near future.
