A step by step guide to growing Marjoram plant in containers

The Marjoram plant spreads like a ground cover and small, oval, light green leaves. Marjoram plant is easy to grow herb well suited for growing in containers as well as the garden.

Types of Marjoram

There are three types of Marjoram plant;

  • Sweet Marjoram,
  • Pot Marjoram, and
  • Wild Marjoram (known as common oregano).

All types of Marjoram plants are equally straightforward to grow and have similar properties, but sweet Marjoram is the mildest variety with the best flavor for using in a wide range of dishes.

Choosing soil and container for growing Marjoram

Select a container that is at least 6 inches wide and has holes at the bottom for the water drain. Pick a one that has a depth of minimum 6 to 8 inches. Once your Marjoram plant outgrows the current pot, you can transplant it into a new one.

Because Marjoram tends to trail, it will want the right container and potting soil to perform optimally as an indoor herb. A pot that is both shallow and wide will provide the surface area to give plant space to spread out. Potting mixes with good drainage designed for cacti or succulent plants will serve Marjoram well. Space plants about 12 inches apart in an area with full sun and fertile, well-drained soil with a pH of 6.7 to 7.0. Add nutrients to native soil by mixing in several inches of aged compost or other rich organic matter.

Growing conditions for growing Marjoram

Marjoram is well suited to a hot, sunny, and arid environment, which means that it is well adapted for indoor container gardening. Marjoram plant needs bright light so place it on the sunniest windowsill you have, or in a window box planter with southern exposure.

Light requirements for growing Marjoram

Marjoram plant requires a lot of light, a minimum of six hours of direct sun per day. If there is no suitable location at home, you may want to invest in a supplemental fluorescent or LED grow light. Make sure that any supplemental lighting is set up about 6 inches above the plant and set on a timer to stay on for twelve hours a day. If you have a sunny outdoor patio, you can place a pot on it during the summer, just be mindful of pests.

Marjoram plant propagation

Marjoram plants can be propagated from seed, cuttings, layering or by dividing the root. The optimum method of vegetative propagation mainly depends on the size and growth habits of the mother plant.

Seeds – Seeds must be sown outdoors when the soil has warmed and all danger of frost has passed. Seeds can be started indoors to produce transplants. Marjoram seeds must be sown indoors 6 to 8 weeks before planting outside. Sow seeds in a sterile seed starting mix in seed trays or pots 0.2 to 1.0 cm (0.08–0.4 in) deep and water gently. Ensure the temperature range remains between 15.5 and 27°C (60–80°F). Seeds must germinate in about 5 days at 21°C (70°F). Due to the slow-growing nature of the plant, many home growers select to start with small plants which can be obtained from a nursery or garden center.

Marjoram plant seed can be slow to germinate outdoors; germination indoors can happen in about 14 days. The seeds of Marjoram are tiny and fine, making them difficult to handle individually. To grow the Marjoram plant from seeds, sprinkle 5 to 10 seeds over the soil and cover them up with a very fine layer of multi-purpose compost. Cover the top about 2/3 of the container with a cling film, ensuring it is not hindering the light. Place the container in an airy location with plenty of sunlight, at a temperature of around 21 to 25°C (70-77°F). The seeds will germinate in 8 days.

Layering – Sprawling Marjoram plant varieties are easily layered by selecting a branch and covering with soil. A rock can be located on top to hold the branch securely under the soil. The branch will increase its root system and once established, can be cut from the mother plant and transplanted to a new site.

Cuttings – Larger and upright plants lend themselves to propagating from cuttings. Cuttings must be taken from approximately 20 cm (8 in) down the stem so that the basal portion of the cutting is hard and woody. The upper 5 cm (2 in) of the cutting could be nipped off to promote branching. Cuttings could be rooted in water, sand or a mixture of sand, peat, and perlite.

Division – Marjoram plant can be grown from root divisions in early spring. Divide roots in autumn and bring roots indoors in pots to produce through winter and then plant out in spring.

Seed germination of Marjoram

Start indoors under grow lamps 6 to 8 weeks before the last frost. Sow seeds just beneath the surface of the soil and seeds will germinate in about 10 days. Set the seedlings in the home garden after all danger from frost has passed. Space plants about 10 inches apart in all directions. If high humidity levels are a problem in the planting area, it is best to space plants further apart to encourage good air circulation. Begin harvesting 5 to 6 weeks after transplanting outdoors, or when plants are growing vigorously.

Sowing Marjoram seed indoors

Sow Marjoram seeds indoors 8 to 10 weeks before the last frost in spring using a seed starting kit. Sow seeds about ¼ inches deep in seed-starting. Keep the soil moist at 70°F and Seedlings emerge in 14 to 21 days.

Provide plenty of light on a sunny windowsill or grow seedlings about 3 to 4 inches beneath fluorescent plant lights turned on 16 hours per day. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this procedure because they will get too hot. Most plants need a dark period to grow, do not leave lights on for 24 hours. If you are growing in small cells, you could need to transplant the seedlings to 3 or 4-inch pots when seedlings have at least 3 pairs of leaves before transplanting to the garden then they have enough room to develop strong roots.

Before planting in the garden, plants require to be “hardened off”. Accustom young Marjoram plants to outdoor conditions by moving them to a sheltered place outside for a week. And be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or brings containers indoors, take them out again in the morning. This hardening off procedure toughens the plant’s cell structure and reduces transplant shock and scalding.

Process of growing Marjoram from seed in containers

For the best results, plan to sow seeds 6 to 8 weeks before the last frost, in early spring. Fill the container of choice with soil to about one inch from the top. Broadcast a pinch of Marjoram seeds over the surface of the soil, and taking care to distribute them as evenly as possible. Water with a watering can so that the soil is completely moist. Cover the pot with cling wrap or plastic and put them in a well-lit windowsill to germinate. Within a week or two, you must see the first sprouts beginning to emerge. Give them a couple of weeks to grow, and pluck out all but the healthiest few plants you want to keep.

Planting Marjoram in the garden

Choose a sunny location with good drainage and slightly acidic soil. Transplant when seedlings have at least 2 pairs of plant leaves. Then dig a hole for each plant large enough to amply accommodate the root ball.

Carefully remove the plant from its pot and gently loosen the root ball with hands to encourage good root development. Locate the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball and press soil down firmly with your hand.

Use the plant tag as a location marker. Thoroughly water and apply a light mulch layer on top of the soil about 1-2 inches to conserve water and reduce weeds.

Process of growing Marjoram from cuttings in containers

Growing Marjoram from cuttings is very simple. Find a mature plant and trim off up to a half dozen stems at least 6 inches long. Pluck the plant leaves from the bottom inch or so of the stems, dip them into rooting hormone, and then plant in pre-moistened soil. You could want to use a chopstick to make a hole for each stem and then gently nestle the soil around it once it’s been inserted.

This is the only time you will ever want to keep the soil of a plant consistently moist for any period. If you use a transparent container for this stage, you can see when the plant roots have extended to the edge, or you can plant in a small 4-inch plastic pot and wait until you see roots coming out of the drainage slots at the bottom. At this point, transplanting the Marjoram plant to a larger pot is ideal.

Marjoram is relatively safe when it comes to serious disease problems. If you have grown the plant in wet soil or weather, it could suffer from root rotting and might damp off.

Harvesting and drying Marjoram plants

In addition to growing Marjoram herbs for aesthetic purposes, people harvest the plant for use in the kitchen. When harvesting Marjoram plant, pick the shoots just before flowers begin to open. This results in the best flavor, as fully opened blooms generate a bitter taste. Bundle Marjoram cuttings and hang them upside down in a dark, dry, and well-ventilated area.

Marjoram plant is ready to harvest after sowing, in 60 days. Snipping leaves with a garden pruner or scissors is the best method to harvest it. Cut leaves as you need, once the plant reaches about 6 inches in height or above. The flavor of the Marjoram plant intensifies in summers and hot weather. Regular harvesting will renew the Marjoram plant’s growth. Do remember Marjoram harvest before it flowers to get the best taste.
