Monarda citriodora

The winter hardy Scarlet bee balm (Monarda didyma), also known under the name Gold Melissa, Horse Mint, Bee balm or Monarda fistulosa, is performing well in every summer garden. The Indians in North America knew of and recognized the healing effects of the labiates. These days, the graceful shrub is primarily being used as an ornamental shrub because of its enchanting, aromatic scent in the respective garden and is suited to be used as a bee pasture in natural gardens.

The Indians in North America already realized its curing effects; this circumstance is where it draws its German name from. The Monarda didyma is also known as the Gold Melissa, Horse Mint, Bee Balm or Monarda fistulosa. Especially because of its popularity, there are ever more cultivated varieties, so that garden enthusiasts have a multitude of choices concerning the color of blossoms.

Care

The graceful scarlet bee balm, Monarda didyma is relatively low maintenance, especially because of its North American origin. It prefers locations at the end of forests or light woods. If all care instructions are being observed, a hobby gardener can have fun with his Scarlet bee balm over several years.

Location

The location, which the Scarlet bee balm desires, should be similar to the one it inhabits in nature. The Gold Melissa prefers a half-shady, light location; direct midday sun should be avoided at all cost. That is why the graceful shrub serves as an ideal company of hedges or below a tree which does not let a lot of light through. Not to be recommended is a sunny bed without any shadow at all.

Soil conditions

The Scarlet bee balm desires for its location a soil, which is similar to the soil at its original location in the nature. You thus offer the ideal soil conditions with the following conditions for your graceful shrubs.

  • permeable
  • slightly moist
  • nutrient rich

In order to insure these soil characteristics, pull compost and peat below the available potting soil.

Substrate

The Gold Melissa, Monarda didyma can also be cultivated in the bucket if there is no fitting location in the garden. This way, it offers a beautiful picture on your terrace or a balcony and can emit its aromatic scent. The used substrate for the bucket should be used in adherence to the following criteria.

  • potting soil for blooming plants
  • keep an eye on nutrients
  • has to be well permeable

Planting time

The ideal planting time for the Scarlet bee balm is usually the spring period. In this event, you should await the ice holies and only afterward, in May, begin with planting. A planting in autumn is not recommended, as the shrubs have too little time to properly grow until the first occurrence of frost and thus stay healthy through winter.

As the shrubs can be multiplied by division, they do not necessarily have to be bought. Especially if the already existing planting Monarda didyma is getting too dense in a bed or bucket, one has to divide and replant.

Planting in the bed

As soon as a fitting location has been found in the bed, the planting can occur. In this case, one has to observe a proper distance to the single plants, as shrubs like to stretch out to the sides.

  • dig holes with a distance of forty centimeters
  • prepare dug out soil with compost and peat
  • place drainage in order to prevent soil wetness
  • doing this, place stones or clay shards into the planting hole
  • place inside Gold Melissa
  • fill in earth
  • lightly press on it and water sufficiently

If you do not give your Scarlet bee balm enough space when planting, it will not grow that fast and the blooming could further be hindered. That is why older, already planted shrubs should be divided and thus rejuvenated in regular intervals.

Planting in a bucket

If no appropriate location in the garden is available for the Scarlet bee balm, you do not have to do without it. The shrub does also perform great in a bucket on a terrace or on a balcony. When planting in a bucket you should abide by the following hints.

  • water can be stowed especially well in a bucket
  • soil wetness is not tolerated at all
  • that is why you should place stones, gravel or clay shards on the drain hole
  • place plant fleece on top of it
  • subsequently add a part of the potting soil
  • plant the Scarlet bee balm inside
  • press on and tighten the rest of the potting soil
  • water sufficiently
  • after half an hour: Drain surplus water from the plate

As the shrubs can reach a height of up to 1,50 meter, the usage of a big bucket is recommended, especially if you want to place several plants together. In order to not face any difficulties to move the big bucket and alter the location to adjust to the circumstances, you should place it before the planting on a movable cart.

Watering

The soil at the location of the Monarda didyma should always be held slightly moist and better not dry out. You should however keep an eye on preventing soil wetness, which can easily occur in buckets.

This is how the Scarlet bee balm is ideally being watered:

  • regularly on hot and dry summer days
  • in the early morning and evening hours
  • in autumn, winter and spring days: Rainy days suffice
  • bucket plants have to be watered more frequently
  • especially if they are located in a rain sheltered position

Fertilizing

Before the Scarlet bee balm drives out again in spring, you should grant the plant a full fertilizing. If the garden’s soil is already containing lots of nutrients, you should only add a few nutrients. It is often sufficient to add compost in spring to the shrub. The plants in the bucket receive a regular fertilizing with liquid fertilizer for blooming plants. In this case, you also start before the first budding occurs.

Cutting

As this plant is a shrub, it will not be cut throughout the year. Only dried blossoms, leaves and stems should be regularly removed in order for new shoots to be able to grow. In autumn, the shrub shows a slight yellow coloring until it fully turns yellow by winter. That is the right time, to completely cut the Scarlet bee balm about a hands breadth above the ground. That way, it can drive out in next spring without any obstacles.

Hibernation

The Gold Melissa (Monarda didyma) is winter hardy that means that its rootstock remains in the earth even throughout the winter months. The upper part, like already explained in the paragraph “Cutting”, is to be removed before winter.

Otherwise, you can protect your Scarlet bee balm from the cold time of the year doing the following:

  • cover young plants with brushwood or mulch
  • older shrubs do not have to be protected
  • bucket plants have to be protected to survive
  • the roots are being damaged faster in a bucket
  • wrap the bucket with brushwood or plant fleece
  • place on Styrofoam

If you have a frost free, or dark room, available like a basement, you can place your bucket into this room for the purpose of hibernation.

Multiplication

The Scarlet bee balm (Monarda didyma) can be multiplied by three ways. First to be mentioned is seeding out, which is often not quite easy. The division of the plants, which makes sense every two to three years to rejuvenate a shrub; as well as the third possibility, the multiplication through cuttings.

Sowing

For sowing, withered blossoms are being collected throughout the summer which contain seeds. These should be stored in a warm, dry location like for instance a boiler room until the next spring.

You can not do anything wrong with seeding is you adhere to a few rules:

  • best time for pre sowing is February or March
  • fill cultivation soil in tiny pots
  • only slightly place the seeds into soil
  • are light germs
  • keep slightly moist, but not too wet
  • cover pots and buckets with transparent foil
  • prevent mold formation
  • ventilate daily
  • place on bright and warm spots
  • plant tiny plants into the bed after the ice holies

If you want to save yourself the sowing in tiny pots, you can directly seed out the seeds after the ice holies in May into the flower bed; doing it this way will slow down growth and blossoming.

Division

A division of the graceful shrubs should be done every two to three years so that the plants stay young. This way they will happily stay blooming. When there is no more space for your Scarlet bee balms (Monarda didyma) in your bed or buckets, a division is inevitable. Furthermore, you can win new plants and this way plant a new bed or buckets with the aromatic beauties.

The following is how a division is being properly conducted:

  • appropriate time is spring time right before budding
  • carefully dig out perennial plants
  • cut the root stocks in two or more parts
  • simultaneously remove dried out roots
  • replant a part at another location
  • before replanting: Add compost and peat below the earth
  • place the other maintained parts on another location

If, at the time of division, there is still frost to be expected, the newly won plants can first be placed in a pot and be positioned in a warmer environment. As soon as the ice holies are finished in May, the plants can be planted inside a bed.

Cuttings

The multiplication by cuttings works fine as well, is normally not being executed until summer though. Because of this, the plants won out of this process will not be ready for planting in a bed until next spring.

We will explain in the following, how to properly cultivate new beautiful shrubs of the Scarlet bee balm:

  • ut shoots without blossoms with a length of 10 – 15 cm
  • if necessary cut blossoms
  • remove all lower hanging leaves
  • fill pots with cultivation soil
  • put inside cuttings
  • keep the soil well moist
  • avoid water logging
  • place on a warm, bright spot

The pots with the cuttings can stay during the time until the first frost stay at sheltered spot. As soon as the first night frost occurs, they should be placed inside. Depending on how developed the cutting is and whether it has grown a sufficient amount of roots, the pot can be placed in a basement for the purpose of hibernation.

Diseases

Mildew has to be mentioned when talking about possible infestations of which the Scarlet bee balm could possibly suffer. Among others, rust can also harm the shrub.

Real mildew

The real mildew can, unfortunately, harm the decorative shrub quite a lot. This disease is classified as a fungal disease which can ultimately lead to the death of the plant. In this case, prevention is a preferable means of fending of the disease and is thus better than having to treat the already infested plant.

A good care is, in this case, the best prevention:

  • suitable location
  • sufficient distance between the plants
  • sufficient and regular watering
  • because mildew likes dry environments
  • remove withered blossoms

If the plant has been infested defying all preventative measures, showing with a white layer on the leaves which will seem in time dirty brown, the only remedy available is a fungicide from a specialist store.

Rust

The herbaceous leaves of the Gold Melissa are also negatively affected by rust. This disease is also a fungal disease. An infestation is being indicated with yellow to brown spots on the leaf’s upper surface. On the lower side of the leaf, little pustules with fungal spores will grow. In this case you should also treat the disease with the respective fungicide from a store. The fungus grows inside of the plant and will damage it until it eventually dies.

Parasites

Unfortunately, not only bees and other insects enjoy the scent of the leaves of the Scarlet bee balm, but also snails like to eat their way through the bed.

Snails

The otherwise very graceful plant can, in the event of a snail infestation, seem very unattractive. Because of this, you should act quickly against the annoying parasites if you notice holes in the leaves.

  • collect them in the early morning and late evening hours
  • erect a barrier around the bed or the single plants
  • snail fence from a store
  • distribute caustic lime or sawdust around the plants

If children or pets are using the garden, you should avoid the usage of snail corn. Snail corn is poisonous and could possibly damage children or curious animals.
