Marshmallow leaves are usually alternate, oval or triangular, with serrated edges and a velvety texture Very characteristic. Its color ranges from deep green to grayish green, depending on the species and growing conditions. The flowers, which are one of the plant's main attractions, are usually white, pink, or red (in the case of Malvaviscus arboreus), and appear mainly in midsummer, although they can continue flowering if the right conditions are maintained.
In addition to its ornamental use, its medicinal value, being traditionally used to treat respiratory and digestive conditions, thanks to its mucilages and bioactive compounds. The marshmallow root is famous for giving rise to traditional marshmallow candies.
Ideal location: sun exposure and climate
Marshmallow is a plant that prefers sunny locationsIt requires prolonged exposure to direct sunlight to grow vigorously and develop abundant blooms. Although some species can survive in semi-shade, this tends to favor leaf growth at the expense of flowers, so it is always recommended to choose bright locations.
The ideal climate for marshmallows is temperate to warm. They adapt well to sunny gardens, but they can also tolerate mild and sporadic frosts If it's well established, it's recommended to protect the base of the plant with mulch made of straw or pine bark, which helps protect the root system from possible damage caused by low temperatures.
It's essential to protect the marshmallow from strong winds, as they can damage its stems and flowers. A location near a wall or hedge can provide the necessary shelter without reducing its sun exposure.
Soil type and land preparation
Success in growing marshmallows in sunny gardens begins with a fertile, light, and well-drained soilIt's important to avoid compact, heavy, or waterlogged soils, as marshmallows are sensitive to excess moisture in the roots, which can cause rot.
To improve the structure of the soil, you can mix garden soil with organic material such as compost, worm castings, or well-cured manure before planting. This will provide the necessary nutrients from the start and promote root development.
If you grow in a pot, use a universal potting soil enriched with organic matter and add perlite or coarse sand to improve drainage. The pot should have holes in the bottom to prevent water accumulation.
Sowing and multiplication
The marshmallow can be reproduced in several ways, mainly by seeds and through cuttings semi-woody in the case of Malvaviscus arboreus. Sowing by seed is simple and allows for new plants to be obtained each season.
- Seed preparation: Soak the seeds for 24 to 48 hours in water to promote germination.
- Planting time: In areas with mild winters, sow in the fall. In regions with cold winters, sow in the spring, once the risk of frost has passed.
- Depth and distance: Sow 1 cm deep, leaving about 50 cm between plants to give them enough space to develop.
Propagation by cuttings is done by cutting segments of semi-woody stems and planting them in moist, well-aerated soil until they take root. Final transplanting to the garden is recommended in late winter or early spring.
Watering: frequency and tips
Watering is one of the most critical factors for the proper development of marshmallows in sunny gardens. Although it is a plant that prefers moist soils, does not tolerate waterlogging. Therefore, it is essential to maintain constant humidity, especially in summer, without overwatering.
- First stage: During the first year, keep the substrate slightly damp carrying out frequent but moderate watering.
- In summer: Water whenever the top layer of soil is dry, increasing the frequency during periods of high temperatures. Potted plants may require daily watering.
- In winter: Reduce watering, making sure the soil does not remain wet for too long.
A useful trick is to use organic mulch to conserve soil moisture and reduce watering frequency during the warmer months.
Fertilization and manure
The marshmallow needs adequate nutrients to develop its abundant foliage and flowers. Before planting, it's advisable to enrich the soil with compost or well-rotted manure. During spring and summer, you can apply light monthly fertilization with a balanced organic or mineral fertilizer.
In the weeks before flowering, an extra dose of fertilizer will promote more flowers and better overall development. It is important suspend fertilization in autumn, since the plant enters vegetative rest and an excess of nutrients could be harmful.
Do not forget that both the lack as excess of fertilizer can negatively affect the marshmallow, so it is essential to find a balance in the application of nutrients.
Pruning: when and how to do it
Pruning is beneficial for stimulate growth healthy marshmallow and maintain the shape of the plant. It is recommended to do so in late winter or early spring before the new vegetative cycle begins. Remove dry, weak, or diseased branches, as well as withered flowers. It is also useful to thin the interior of the plant to allow light to enter and air, which helps prevent disease.
Always use disinfected and precise tools to avoid damaging the plant or facilitating the entry of pathogens.
Prevention of pests, diseases and common problems
Marshmallow is a plant relatively resistant to pests and diseases. However, overwatering or waterlogged soils can promote the development of fungi, such as root rot. In humid conditions, it can also be attacked by aphids or mealybugs.
- Prevention: Maintain good drainage and avoid waterlogging. Monitor the plant regularly for early signs of pests.
- Treatment: If you notice pests, you can use insecticidal soaps or organic horticultural oils. Fungus can usually be prevented by improving soil ventilation and drainage.
Frequently inspect both the underside of leaves like young shoots to act in time and ensure that the marshmallow maintains its health and vigorous appearance.
