I have just harvested 10 Rosabelle potato plants, which were planted in a garden near a hazelnut hedge. I planted them the day after Saint Joseph's Day, on March 20, 2020. The yield is 4.5 kilograms, and it is certain that the other plants further away from the hedge will be more profitable. However, this is a potato variety that is well-suited for making French fries and sautéed potatoes.

The 'Rosabelle' potato is a semi-early variety, producing potatoes with red skin and tender, yellow flesh. The potatoes have a melting texture while maintaining good cooking properties. They can be fried, stewed, or baked. Plant the tubers from mid-March to May, depending on the climate, and harvest approximately 110 days later.
The potato is a root vegetable that has become essential in both the garden and the kitchen. It is a perennial plant cultivated as an annual, developing tubers as storage organs on its rootstock. Apart from a few varieties like 'Belle de Fontenay', the plants produce small flowers in summer. Each plant will produce several potatoes, which can be stored for several months and cooked in multiple ways. The potato belongs to the Solanaceae family, along with aubergine and tomatoes. Originally cultivated in the Andes Mountains, it was brought to Europe in the 16th century.
There are many different varieties. The tubers, which can be somewhat elongated in shape, generally have yellow flesh, but sometimes they can be red, pink, or purple. Low in calories, potatoes are rich in carbohydrates, iron, and potassium.
There are three categories of potatoes, based on their flesh content:
- Firm-fleshed varieties have good cooking properties. These potatoes, which are usually elongated in shape, have fine and tasty flesh. They are ideal for boiling or steaming, and can also be stewed or pan-fried.
- Floury-fleshed varieties are rich in starch and easily break apart. These fairly large potatoes are perfect for mashing or soups. They also make perfectly crispy fries as they tend to absorb less oil when cooked.
- Waxy-fleshed varieties have a melting texture while still retaining good cooking properties. They can be used in multiple ways: pan-fried, stewed, or roasted.
Harvesting
Depending on the variety and their maturity, potatoes can be harvested from May to October. Gently lift the plants with a garden fork to avoid damaging the tubers. Let the potatoes dry in the sun for a day.
Storage potatoes should be harvested when the foliage turns yellow and withers. Early varieties are harvested 80 to 90 days after planting, mid-early varieties around 110 days, semi-late varieties around 120 days, and late varieties from 120 to over 150 days.
As for new potatoes, which have very thin skin and delicious flesh, they are harvested before maturity, around 70 days after planting. Harvest them just after flowering, around May-June.
Storage
After removing any damaged tubers, store the potatoes in a cool, dry, and dark place. In the presence of light, the tubers turn green and produce a toxic compound called solanine. Early harvested varieties should be consumed quickly. Storage potatoes can be stored for several months. The storage duration varies depending on their maturity: late varieties can be stored the longest.
Gardener's tip
Grow potatoes as part of a crop rotation, as they are often considered a cleansing crop. The hilling process and root development leave the soil clean and loose after harvest. Potatoes also benefit from being grown near legumes such as beans, broad beans, and peas.

Planting
Potatoes need light, deep, and rich soil. Choose a sunny location. Add well-rotted compost in the previous autumn, by hoeing it into the soil to a depth of 5cm (2in), after loosening the soil. Planting takes place under shelter in February-March for early varieties. For other varieties, plant them from mid-March to May, depending on the climate. Wait until the soil is at least 10°C (50°F). The flowering of lilac is often a sign to start planting. Plant several varieties in your vegetable garden for a varied menu.
Loosen the soil deeply and form rows 10cm (4in) deep, spaced 70cm (28in) apart. Place the tubers, sprout upwards, every 40cm (16in) (or 30cm (12in) for early varieties). Cover with fine soil. When the plants reach 15cm (6in), mound up by bringing fine soil to the base of the stems, to a height of 20cm (8in). Mounding up encourages tuber formation and water drainage. You can mound them up again a month later. Mulch the base of the plants with successive thin layers of grass clippings mixed, if possible, with dead leaves. This protection keeps the soil moist and limits weeding.
Potato cultivation does not require watering, except in case of high temperatures. In this case, water the base without wetting the foliage to prevent the appearance of fungal diseases.
Diseases and pests
Potatoes are susceptible, like tomatoes, to late blight. This is a fungal disease caused by the fungus Phytophthora infestans. Late blight develops in warm and humid weather. Small spots appear, which are white underneath the leaves and brown on top. As a preventive measure, here are some tips to limit the risk of late blight:
do not grow several plants of the Solanaceae family (such as potatoes, tomatoes, aubergine, peppers, and chili peppers) in adjacent rows, as they are susceptible to the same diseases
in terms of rotation, wait 4 years before growing a Solanaceae plant in the same location
space the plants, both within and between rows, to encourage air circulation and prevent rapid disease spread
if you need to water, do not wet the foliage
spray preparations such as horsetail decoction or garlic purin
Harvesting can also be hindered by the Colorado potato beetle, an insect of the Coleoptera order. You will recognise it by its yellow head and its yellow and black striped body. The best solution, although a bit time-consuming, is to remove them as they appear. As a preventive measure, sow blue flax seeds between your rows of potatoes. Sow from April to June in shallow furrows. Besides its repellent effect against Colorado potato beetles, flax will brighten up the vegetable garden with its pretty little blue flowers. You can also interplant peas between your rows of potatoes.
Other planting methods
The detailed planting method above is the most common. Other methods exist, such as mulch planting and tower planting.
Mulch planting involves placing the tubers on the ground and covering them with a layer of mulch. This protection is supplemented as the plant grows, with the tubers always being kept away from light.
Tower planting or bag planting is practical for small spaces but requires regular watering. The tower can be built from various materials (wood, wire mesh, tyres). The tubers are placed on a bed of potting soil or compost. As the plant grows, it is covered with more potting soil, leaving only the topmost leaves exposed, until reaching the top of the tower, letting the tubers form throughout the height of the container.
Harvest when the foliage has dried up.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
