What is spearmint?

Spearmint is an aromatic plant that belongs to the Mentha genus. It is known for its refreshing flavour and intense fragrance.

It is also commonly grown in gardens, pots, or urban allotments because it is very hardy and adapts to any space. Its main appeal lies in its culinary and medicinal uses, so you will find it in drinks, dishes, and health products.

What are the characteristics of the peppermint plant?

Before discovering how to care for spearmint, let's take a look at its main characteristics:

• It has green, shiny, and very aromatic leaves: These are known for their intense minty scent.
• It has thin, flexible stems:  which allow it to grow more quickly and spread out.
• They are fast-growing: This means they tend to become invasive if not properly controlled.
• High concentration of essential oils: These are found in its leaves and are responsible for its freshness and famous flavour. 
• It is a perennial plant in mild climates: It is capable of remaining productive throughout the year with the correct care.

When to sow or plant mint?

The ideal time to sow or plant mint is during spring. This is when temperatures begin to rise and frosts become less frequent. However, when grown in greenhouses, it is possible to change the date and organise everything at different times of the year. The important thing is to ensure a temperate environment and moderate watering during rooting.

What care does the mint plant need?

Now we will tell you about caring for mint so that you can take these tips and have beautiful aromatic plants.

Suitable light for mint

Spearmint thrives in indirect light or gentle sunlight for several hours a day. Although it tolerates partial shade, too much darkness reduces its aroma and causes its stems to stretch.

In a greenhouse, it is best to place it in areas where it receives constant light without direct exposure to intense sunlight.

Watering recommendations

This plant enjoys humidity, but you should not overwater it. It is best to keep the soil slightly moist and water it when the top layer begins to dry out. Inside the greenhouse, the humidity is usually higher, so you will need to check it frequently and prevent mould from forming.

Best soil for spearmint

Part of caring for mint is knowing how to choose the right soil. This plant grows in loose soil with plenty of organic matter. You must ensure good drainage and use a universal substrate mixed with a little compost.

It also works very well in pots, provided they have drainage holes to prevent excess water.

Subscriber frequency

If you want the plant to grow quickly and strongly, you should apply organic fertiliser every four to six weeks during the active season. This will promote better daughter plant production and help the plant recover from pruning. And remember that growth slows down in winter, so fertilising will not be necessary.

Proper pruning of mint

It is necessary to prune frequently to prevent premature flowering and prevent it from losing some of its flavour. Simply cut the tips to stimulate new shoots and maintain a compact shape. In addition, pruning in a greenhouse also helps to improve ventilation between the leaves.

Pest and disease protection

To conclude with the care of mint, we must discuss pests and diseases. These plants can be affected by:

• Aphids
• Red spider
• Whitefly

Leaves should be checked frequently and the greenhouse ventilated to prevent these problems. If pests appear, it is best to use environmentally friendly treatments such as potassium soap or neem oil.

How to cut the mint plant?

It is recommended to cut the stems above a node, preferably in the morning when the plant is most hydrated. This stimulates lateral growth and produces more tender leaves.

Similarly, it is best not to remove more than a third of the plant in a single harvest, as this can weaken it.

Best garden greenhouses for planting mint

Now you know more about caring for mint. However, you also need to know the ideal structures for your crop to be successful. At FERTRI we have several greenhouses made with quality materials and adapted to different planting and growing projects.

With them, you can grow mint in different seasons of the year and control all the conditions that this plant needs. One of the models you can choose to start with is the tunnel greenhouse, which is lightweight and has a design that facilitates good air circulation.

On the other hand, there is the straight-walled tunnel greenhouse . This stands out for its height, ideal if you want to combine mint with other aromatic plants or install side shelves. Its design optimises space and allows you to work comfortably.

What if you are looking for a more compact alternative? Here you can choose the mini tunnel greenhouse because it is perfect for individual pots or small rows of mint. It keeps the temperature stable and protects the roots from direct cold.

Finally, there is also the mini wide span greenhouse, which combines aesthetics and functionality. It is a very practical option for terraces and small gardens. Its structure allows it to maintain good humidity without compromising ventilation.
