What Do You Need To Start Growing Marjoram?

You may want to pick up a fertilizer to have on hand, too. Since marjoram is grown for its leaves, encouraging foliage growth with the right nutrients is essential. A well-balanced 10-10-10 fertilizer or even some compost tea should do the trick.

In the meantime, you can read on below to learn everything else you need to know about growing marjoram. It's pretty simple, as are most herbs, but there are just a few key things you need to remember.
How Long Does It Take To Grow Marjoram?
Marjoram seeds take a long time to germinate - usually anywhere between two and three weeks.
However, you’ll be able to harvest your leaves about 60 days after sowing. Other things may delay this, including weather & light exposure, soil fertility, etc.
Starting Marjoram Seeds Indoors Before Moving Outdoors
To do this, you’ll need to plan ahead to start your seeds about eight to ten weeks before the last expected frost date in the spring.
Sow your seeds about a quarter of an inch deep in seed-starting formula and keep the soil moist, around 70 degrees, until the seedlings emerge.
Like most herbs, it can take some time for seedlings to appear - up to three weeks, in many cases. Once they do, provide lots of light, keeping them about four inches beneath grow lights that are turned on for 16 hours per day.
Do this when the plants are around four weeks old. Depending on the size of your seed starting cells, you might need to transplant your seedlings when they have three pairs of leaves, too, putting them in larger containers until you’re ready to transplant them into the garden.
Planting Marjoram Seedlings In The Garden
Before you plant your marjoram seedling in the garden, you need to take some time to harden them off. This will allow them to build the defenses necessary to handle the harsh wind, sun, and temperature conditions outdoors.
To harden off your seedlings, start by putting them outside for just an hour or two each day. Every day, add a few more hours until the seedlings are able to spend all day outdoors.
This will toughen their cell structure and reduce the risk of transplant shock. Plant your seedlings in average soil, selecting a location that receives full sun. wait until the danger of frost has passed. Work a bit of compost into the soil, digging in about seven inches.
Transplant when your seedlings have two pairs of leaves and dig a hole that is large enough to generously accommodate the entire root ball of the plant.
Remove the plant from the pot with care, loosening the roots as you do so. Arrange the root ball so it is even with the level of the surrounding soil, then fill with soil to the top.
Press down firmly with your hand and water thoroughly. Apply a bit of mulch around the transplant to reduce weeds and conserve water.
What Conditions Does Marjoram Like?
Marjoram plants should be grown about 12 inches apart in full sun. It prefers rich, well-draining soil with a pH between 6.7 and 7.0. It should remain well-watered but not too wet.
Monitoring Marjoram Diseases & Problems
Marjoram is a relatively hardy plant with few pest and disease problems to worry about. However, there are a couple to keep an eye out for.
One is botrytis blight. Also referred to as gray mold, botrytis blight causes a fungus to appear on plant stems and leaves.
The diseased leaves will fall off and die. If the infection is severe, the entire plant might die. It flourishes in high humidity and cool temperatures.
The best way to prevent botrytis blight is to make sure your plants have proper air circulation by spacing and pruning them appropriately. If you're growing indoors, this requires some circulation fans.
Another issue you might encounter is damping off. This disease often happens when you are starting plants from seed.
It’s hard to detect, too, as the seedling will emerge and appear to be healthy - then, it will start to wilt and die for no apparent reason.
It is also caused by a fungus that thrives in high humidity. If your soil is too wet or contains too much nitrogen, your plants are at an increased risk. Avoid overwatering and again, provide proper air circulation.
The primary pest of marjoram is the aphid. These sucking insects spread disease as they feed on the undersides of marjoram leaves. They also leave behind a sticky substance, honeydew, that attracts ants.
Does Marjoram Grow Back Every Year?
Depending on where you live, you might be able to keep your marjoram going strong for many years.
In zones 9 and warmer, marjoram is a perennial and can be left in the ground between
seasons. In northern climates, it’s only an annual, so you may be better off putting it in a container and bringing it indoors for the winter.
How To Harvest & Store Marjoram
You can begin to harvest your plants when tips appear at the ends of the stems. These should look like tiny little balls.
Cut the plants back close to the ground at this time, which will encourage a new flush of growth. This second growth is often more desirable than a first cutting, possessing far more flavor.
You can air-dry the cut stems and store them in sealed containers. Alternatively, you can dry the leaves in a dehydrator. Discard the stems and keep only the leaves. They’ll last for several months when dried this way.
