Gardening in a northern climate presents a unique set of challenges and rewards. With a short growing season, long winter months, and the phenomenon of the midnight sun, maintaining a yard in Finland requires specific knowledge and timing. Whether you are looking to grow your own vegetables or simply want a lush, green lawn, understanding the local conditions is the first step toward success. This guide provides practical steps to help you navigate the Finnish seasons and keep your outdoor space thriving year-round.
Understand Your Hardiness Zone
Finland is divided into several plant hardiness zones, ranging from Zone I in the south to Zone VIII in the northernmost parts of Lapland. Knowing your zone is essential before purchasing any plants or seeds. Most garden centers label their plants with these zone ratings to indicate whether a species can survive the winter in your specific location.
Plants that thrive in Helsinki may not survive a winter in Oulu or Rovaniemi. Always choose varieties that are rated for your zone or one zone higher for added security. Local Finnish varieties, often labeled as “FinE” (Finnish Elite), are specifically bred or selected for their hardiness and suitability to the northern climate.
Spring Cleanup and Soil Preparation
The Finnish gardening season begins the moment the snow melts. This is a critical time for cleanup and preparation. Once the ground is no longer frozen and the soil has dried out enough that it doesn’t stick to your boots, you can begin your spring maintenance routine.
Clear the Debris
Start by raking away dead leaves and twigs that have accumulated over the winter. This allows the soil to breathe and helps the grass beneath wake up. Be careful not to rake too aggressively if the ground is still soft, as you might damage the roots of the grass.
Soil Testing and Fertilizing
Finnish soil is naturally acidic. Most garden plants prefer a more neutral pH, so applying garden lime (turve- tai puutarhakalkki) in the spring is a common practice. After liming, wait a week or two before applying a balanced spring fertilizer. This provides the necessary nitrogen boost for early growth.
Maximizing the Short Summer Season
Summer in Finland is characterized by intense light and relatively mild temperatures. Because the sun stays up for most of the night, plants grow at an accelerated rate compared to southern Europe. However, this also means they require more consistent care during the peak months of June and July.
Watering Strategies
Even though Finland is known for its lakes, summers can have dry spells. The long hours of daylight can dry out the soil quickly, especially in raised beds or containers. Water your garden early in the morning or late in the evening to minimize evaporation. Focus on the base of the plants rather than the leaves to prevent fungal diseases.
Mulching for Moisture
Using mulch, such as lawn clippings or bark mulch, is highly effective in Finnish gardens. It helps retain moisture in the soil, suppresses weeds, and as it breaks down, it improves the soil structure. This is particularly helpful for vegetable patches where consistent moisture is key to a good harvest.
Essential Autumn Winterization
In Finland, autumn is perhaps the most important season for a gardener. How you prepare your yard in September and October determines how well your plants will survive the harsh winter ahead. The goal is to help plants enter dormancy safely.
Pruning and Cutting Back
Prune deciduous trees and shrubs once they have dropped their leaves, but avoid heavy pruning of fruit trees until late winter or early spring. For perennials, you can leave the dead stalks standing; they provide a natural habitat for beneficial insects and can help trap snow, which acts as an insulator for the roots.
Protecting Sensitive Species
Evergreens and certain ornamental shrubs are susceptible to “winter burn” in late winter when the sun begins to shine but the ground is still frozen. Wrap these plants in burlap or specialized garden fabric in late autumn to shade them from the harsh spring sun and drying winds.
Planting Bulbs
September and October are the perfect months to plant spring-flowering bulbs like tulips, daffodils, and crocuses. Plant them at a depth three times the height of the bulb. The cold winter period is actually necessary for these bulbs to trigger their growth cycle in the spring.
Maintaining Yard Structures and Equipment
A Finnish yard often includes more than just plants. Saunas, storage sheds, and temporary structures like tarpaulin garages (pressutallit) require their own maintenance to withstand the weight of snow and the effects of moisture.
- Check Roof Loads: Ensure that all outbuildings are structurally sound. During heavy snow years, you must clear the roofs of sheds and greenhouses to prevent collapse.
- Drain Water Systems: Always drain outdoor taps and hoses before the first frost. Water freezing inside pipes can cause them to burst, leading to expensive repairs in the spring.
- Protect Furniture: Store wooden garden furniture in a dry shed or cover it with heavy-duty waterproof covers. The constant cycle of freezing and thawing is very damaging to wood finishes.
Dealing with Local Wildlife
Finnish gardeners often share their space with hares, deer, and moose. These animals can cause significant damage during the winter when food is scarce. Protecting your investment is a key part of yard maintenance.
- Install Fencing: Use sturdy wire mesh around the trunks of young fruit trees to prevent hares from gnawing on the bark.
- Use Repellents: There are various scents and sprays available that can deter deer from entering the garden area.
- Netting: In the summer, use netting over berry bushes like currants and strawberries to protect the harvest from birds.
Conclusion
Successful gardening in Finland is all about working with nature rather than against it. By choosing hardy plants, preparing the soil correctly, and taking the time to winterize your yard properly, you can create a beautiful and productive outdoor space. Remember that every season has its tasks, and staying ahead of the weather is the best way to ensure your garden remains a source of joy.
