Choosing the variety for sowing peas
Pea varieties adapted to the French climate
To successfully grow peas, it's important to select varieties adapted to French climatic conditions. Northern regions, which are cooler and wetter, favor early varieties that can withstand low temperatures. In the south, mid- to late-maturing varieties are better suited, as they tolerate heat better and allow for staggered harvests. Among the cold-resistant varieties are... Little Provençal et Sweet Provencewhile varieties such as Carouby de Maussane ou Kelvedon Wonder are excellent for warmer regions.
Early, mid-early and late varieties for sowing peas
Early varieties are ideal for sowing peas at the beginning of the season, as they germinate quickly and provide an early harvest. They typically grow to between 50 and 70 cm tall and are more resistant to light frosts. Mid-early varieties are more versatile and offer harvests over a longer period, while late varieties, often climbing and vigorous, require sturdy support and are suitable for summer harvests. The choice therefore depends on the planned sowing period and the desired harvest duration.
Examples of popular varieties grown in France
Among the most cultivated varieties in France, we can mention Little Provençal, Sweet Provence, Carouby de Maussane, Kelvedon Wonder, Laxton's Progress et LincolnDwarf varieties are suitable for planting in close rows or in pots, while climbing varieties require supports and offer higher yields. Selection also depends on taste, grain size, and resistance to diseases specific to each region.
Where to plant peas?
Choice of location
To successfully cultivate peas, it is essential to choose a sunny location. They prefer a south or southeast exposure, which guarantees them enough light for good growth. Avoid areas with excessive shade, as a lack of light can slow the growth of the plants and encourage the appearance of diseases.
Ideal soil type
Peas thrive in light, moist, and well-drained soil. Loamy or sandy loam soil is ideal, allowing roots to develop well while maintaining good moisture. Avoid heavy, clayey, or poorly drained soils, which can cause waterlogging and lead to root rot problems.
Soil preparation
Before sowing peas, it's important to prepare the soil thoroughly. Start by tilling or digging to aerate the soil to a depth of 20 to 25 cm. Remove any stones and weeds that could compete with the plants. Then, add an organic amendment, such as well-rotted compost or composted manure, to enrich the soil with nutrients and improve its structure. Be sure to incorporate these amendments well into the topsoil. If the ground is compacted or poorly drained, consider creating raised beds or furrows to facilitate water runoff.
Crop rotation
To avoid soil depletion and limit the development of diseases, crop rotation is essential. Peas, which belong to the family of legumes, have the ability to fix atmospheric nitrogen through their root nodules. It is therefore recommended not to plant peas in the same place for several years in a row. Alternate with non-legume crops such as root vegetables (carrots, beets) or leafy vegetables (lettuce, spinach). This practice helps preserve soil fertility and reduce the pressure of pathogens specific to peas.
Sowing peas
Optimal sowing period
Peas are generally sown in early spring, as soon as the soil has warmed up sufficiently, around 8 to 10°C. In regions with mild winters, sowing can also be considered in late autumn for an early harvest. It is important not to sow too early in cold, wet soil, as this can cause seed rot. Sowing can also be spread over several weeks to spread out the harvest.
Choosing varieties adapted to the climate
There are several varieties of peas, including round or wrinkled, early or late-growing, brittle or shelled varieties. To optimize your crop, choose a variety suited to your climate and season. For example, fast-growing varieties are suitable for short-season climates, while later-growing varieties may be preferred in areas with a long season.
Sowing techniques
Peas are sown directly in the ground. Sow the seeds in straight rows spaced about 30 cm apart to facilitate maintenance and staking. Alternatively, sow in clusters of 3 to 5 seeds, then thin to one or two plants per cluster after germination. This method allows for better control of plant density and vigor.
Seed Depth and Spacing
Seeds should be sown at a depth of 3 to 5 cm, never too deep to promote good germination. Seed spacing in the row should be approximately 5 cm, which prevents excessive competition between plants while maximizing available space. Proper spacing promotes better air circulation and limits the development of diseases.
Post-sowing care for peas
spray
Peas need moist soil, especially during the flowering and pod formation period. Water regularly, focusing on the base to avoid wetting the foliage, which can encourage disease. Watering frequency will depend on the weather and soil type, but generally, a weekly watering will be sufficient if the soil does not retain moisture well.
Mulching to retain moisture and limit weeds
Mulching with straw, dead leaves, or organic mulch helps keep the soil moist longer and reduce weed growth. It also limits water stress and protects the roots from temperature fluctuations. Make sure to apply a sufficient layer (5 to 7 cm) while leaving some space around the stems to avoid stagnant moisture.
Staking and supporting plants
Climbing peas require support to thrive. Install stakes, netting, or vertical branches as soon as they emerge to guide the shoots. This facilitates air circulation between the plants, reduces contact with the soil, and makes harvesting easier. For dwarf varieties, staking is not required, but it can still help keep the plants clean and well-ventilated.
Manual and mechanical weeding
Regular weeding is essential to prevent competition between peas and weeds, which draw water and nutrients from the soil. Weeding should be done manually to avoid damaging the surface roots. You can also gently run a hoe or cultivator between the rows, taking care not to damage the plants. Avoid excessively disturbing the soil around the roots.
Fertilization for growing peas
Specific nutritional needs
Peas, as legumes, have the unique ability to fix atmospheric nitrogen through their root nodules. This reduces their nitrogen requirements in the soil, but they still require other nutrients such as phosphorus, potassium, calcium, and trace elements to ensure healthy growth and good production.
Recommended types of fertilizers
To effectively feed peas, it is advisable to use mainly organic amendments such as mature compost or composted manure, which slowly add nutrients and improve soil structure. It's best to avoid chemical fertilizers, as overuse can unbalance the soil, reduce biodiversity, and promote foliage growth at the expense of pods. They can also pollute groundwater and weaken plants' natural resistance to disease and pests.
Schedule and method of application
Fertilizer should be applied before sowing, incorporating organic amendments into the soil during preparation. Avoid excess nitrogen, which stimulates leaf growth at the expense of seed production. Always apply fertilizers at the base of the plants for better absorption.
Prevention and treatment of pea diseases
Common illnesses
Peas can be affected by several diseases, including fungal infections such asanthracnose, gray mold (botrytis), rust and powdery mildew, as well as bacterial diseases and viruses.
Anthracnose appears as brownish spots on stems and pods, and rust appears as small orange pustules on the undersides of leaves. Powdery mildew appears as a white felting on the leaves, fusarium wilt causes plants to wilt and yellow, while root rot leads to general drooping.
Viruses, often transmitted by aphids, can cause deformations, stunted growth and general yellowing, significantly reducing yield.
Identifying symptoms
It's important to monitor plants regularly to quickly detect signs of attack. Look for deformed, yellowed, or powdery leaves, wilted stems, and soft or blackened roots. Careful observation allows for timely intervention and limiting the spread.
Preventive cultural measures
To limit the risk of disease, adopt a rigorous crop rotation and avoid planting peas in the same spot for several years in a row. Disinfect your gardening tools regularly to prevent the transmission of pathogens. Maintain sufficient spacing between plants to ensure good air circulation and reduce moisture on the foliage.
Possible natural treatments
In the event of an attack, first opt for natural treatments, such as spraying Bordeaux mixture for fungal diseases, or using plant purines to repel aphids and other harmful insects. Horsetail, tansy, or comfrey purines are particularly effective at strengthening plant defenses and repelling certain pests. These solutions protect peas while respecting the ecological balance of the garden, thus reducing the need for chemical insecticides and promoting a healthy and sustainable crop.
Sowing peas: pest control
Main pests
Peas are susceptible to several pests such as aphids, seedpod flies, and flea beetles. Aphids feed on the sap and can transmit viruses, while seedpod flies attack young seedlings, causing them to wilt. Flea beetles, small jumping fleas, bore into the leaves, leaving visible holes that weaken the plant.
Prevention methods
To prevent these attacks, promote biodiversity by planting flowers that attract beneficial insects (ladybugs, hoverflies), which are natural predators of aphids. Also use insect netting to protect young plants, and practice intercropping with repellent plants such as nasturtium or borage.
Adapted treatments
In case of infestation, favor biological treatments such as neem manure or insecticidal soaps, which are effective against aphids and other small insects. For flea beetles, a treatment with diatomaceous earth can limit their presence. Chemical insecticides should only be used as a last resort and with caution, so as not to harm beneficial insects and to respect pre-harvest deadlines.
Pea cultivation: harvesting and storage
Ideal harvest time
Peas should be harvested when the pods are well-filled but still tender. For fresh-grain varieties, pick them when the seeds are still tender, before they harden. For shelling peas, harvest when the pods are well-formed and beginning to turn slightly yellow. Regular harvesting is recommended to boost production and prevent the pods from becoming overly large and fibrous.
Harvesting techniques to preserve the plant
Harvest the pods by hand, gently pinching them off, without pulling sharply on the plant to avoid damaging the stems and branches. Use a basket or lightweight container to avoid crushing the harvest. It is best to harvest in the morning, when the pods are still fresh and crisp.
Storage and preservation of seeds for future sowing
If you want to save seeds for the following season, let a few pods ripen on the plant until they dry out and turn completely yellow. Then harvest them, open the pods, and extract the seeds. Dry them well in the shade in a dry, ventilated place. Store the seeds in paper bags or airtight containers, away from moisture and light to preserve their germination capacity.
Tips for Successfully Growing Peas
Managing climatic hazards
Peas are sensitive to late frosts in spring and high heat in summer. To protect young plants from frost, use a protective fleece or sow in a cold frame. In case of prolonged drought, increase watering frequency and maintain a thick mulch to retain soil moisture.
Favorable associations with other plants
Peas benefit from beneficial associations with certain plants such as carrots, lettuce radish or cucurbits. These companions can improve plant health, repel certain pests, or optimize garden space. However, avoid planting them near onions or garlic, which can inhibit their growth.
Optimizing production in a small space
To grow peas in a small space, choose dwarf or semi-fast growing varieties. Use vertical supports such as trellises or netting to maximize growing area. Also, consider staggering sowings over several weeks for continuous production and better use of available space.
Conclusion
Growing peas requires careful attention from soil preparation to harvest. By following these key steps—site selection, proper sowing, regular maintenance, and careful monitoring for diseases and pests—you can ensure a healthy and abundant crop. Crop rotation and natural prevention methods are essential for maintaining soil and plant health. With a little patience and attention, peas become an accessible crop, even in small spaces.
