The planting zone confirms which species can be grown in the area. Here, learn which plants are grown in WI and what planting zone is WI in according to USDA.
Zones 3a through 5b of the USDA’s plant hardiness map encompass Wisconsin. Zone 3a applies to the state’s northern region, whereas Zones 4a to 5b apply to its southern region.
These planting zones indicate which plants are most likely to grow in a certain climate and are based on the region’s average lowest winter temperatures.
For the best possibility of success, Wisconsin gardeners should select plants that are appropriate for their specific hardiness zone.
Here learn all about the planting zones in WI and the types of species you can grow or not in this region.
Relationship between Temperature and Plant Hardiness in WI
Temperature affects the potential of plants to develop and flourish in a certain area, making it a significant component.
Based on the region’s typical minimum winter temperature, the USDA Plant Hardiness Zone Map is a tool utilized to figure out the best planting zone for various plant species.
Wisconsin experiences four distinct seasons in a continental climate. Based on the season and the area of the state, Wisconsin has a wide range of temperatures.
- Temperatures progressively drop over the fall months of September to November, with average highs varying from the mid-50s °F (12–14 °C) in the north to the mid-60s °F (18–20 °C) in the south.
- In late September, particularly in the northern region, the lowest points below freezing at night are not uncommon.
- Temperatures in Wisconsin can get fairly low during the winter (December to February), especially in the state’s north.
- The mid-teens °F (-9 to -6 °C) in the north to the low-30s °F (-1 to 0 °C) in the south are the average high temperatures in January.
However, during cold snaps, temperatures in the state’s northern section can fall considerably below zero (-18 °C or below).
Temperatures gradually increase over the spring months of March through May, with typical highs varying from the mid-30s °F (2-4 °C) in the north to the mid-50s °F (12–14 °C) in the south.
Snow and freezing temperatures are still possible in the early spring, but temperatures can still vary greatly.
Plants Hardy To Wisconsin’s Planting Zone
If you want a successful garden in Wisconsin, which has a chilly climate and lengthy, snowy winters, you must select plants that are suited to the region’s climate.
The following plants are known to endure Wisconsin’s winters:
Evergreen trees and shrubs have the capability to retain their foliage or needles during the winter, letting them withstand the chilly temperatures and brisk winds.
Examples of evergreens are spruce, pine, and fir. Boxwood, juniper, and holly are a few additional evergreen shrubs that work well in Wisconsin.
Several perennials, such as coneflower, black-eyed Susan, hosta, daylilies, and sedum, are adapted to Wisconsin’s environment.
The aforementioned plants will wither away throughout the winter; however, they will reappear in the spring.
Daffodils, tulips, and crocuses are among the bulbs that can withstand Wisconsin winters’ chilly temperatures and blankets of snow. The spring blooming season is when they can be sown in the fall.
Switchgrass, small bluestem, and feather reed grass are just a few of the beautiful grass types that can last the Wisconsin winter.
- Fruit plants like apple, cherry, and plum trees are some examples of fruit trees that can endure Wisconsin’s harsh winters.
- Kale, spinach, carrots, and Brussels sprouts are a few veggies that can withstand the chilly weather and frost of Wisconsin winters.
It’s crucial to remember that even hardy plants might suffer harm or die if they are exposed to extremely cold temperatures or a lot of precipitation.
Mulch around the plants to protect them and shield them from blizzards so they can survive the winter.
It is important to remember that other factors, besides temperature, also have an impact on plant growth and hardiness.
Pests, soil type, moisture, sunlight, and other elements can all affect a plant’s ability to grow and survive.
Therefore, it’s critical to select plants that are suitable for your region’s unique characteristics, not just its temperature range.
Plants that Do Not Survive in the Winters of Wisconsin
Many plants in Wisconsin may struggle in the hard winter climate, and some may not even make it through the season.
Examples of plants that might have a hard time surviving Wisconsin’s winters are as follows:
- Plants native to tropical or subtropical regions, such as citrus trees, palm trees, and banana trees, are unlikely to survive Wisconsin’s harsh winters.
- Tender perennials with warmer-climate ancestry may have trouble surviving Wisconsin’s harsh winters. Lavender, rosemary, and numerous succulent plant species are examples.
- Warm-season annual plants that are sown in the spring and, like impatiens, petunias, and marigolds, may not endure Wisconsin winters’ chilly temperatures.
- Some tender bulbs, like gladiolus and tuberous begonias, are not resilient enough to endure the bitter Wisconsin winters.
- Although many fruit trees can thrive in Wisconsin, some species can struggle in the state’s severe winters. As an illustration, consider peach trees, which are susceptible to harm from freezing temperatures throughout the winter and from changing springtime temperatures.
To ensure your plants’ longevity, it’s critical to pick plants that are appropriate to the local environment. If you’re unclear whether a specific plant will endure Wisconsin’s harsh winters, you might ask a nearby nursery or gardening professional for guidance.
How To Maintain Plants In Wisconsin?
In Wisconsin, taking care of plants necessitates paying attention to the particular difficulties posed by the state’s climate. The following advice is about taking care of plants in Wisconsin:
Pick plants that can withstand Wisconsin’s climate. As was previously mentioned, it’s crucial to pick plants that will thrive in your area’s environment. Look for plants that can withstand Wisconsin’s harsh winters and summer heat.
Plant in the appropriate season. Grow perennials and trees in autumn to give them time to grow roots before winter arrives. Warm-season veggies, bulbs, and annuals should all be planted in the spring.
Use water carefully! In Wisconsin, the growing season is when plants require a lot of water. Water thoroughly and frequently, especially in hot, dry weather. Avoid waterlogging, too, since this can cause root decay.
Apply a layer of mulch around the base of plants to help maintain moisture, control soil temperature, and guard against frost heave.
Protect plants from inclement weather. In the winter, cover plants with burlap or other weatherproof materials to shield them from blustery winds, heavy snowfall, and freezing temperatures. For plants that are susceptible to high temperatures, give shade during the summer.
Appropriate fertilization is important. To give plants the nutrients they require to grow and thrive, fertilize them in the spring and summer with a balanced fertilizer.
Aphids, spider mites, and powdery mildew are a few examples of pests and illnesses to be on the lookout for. Infestations should be treated quickly to avoid plant harm.
You may encourage your plants to grow in Wisconsin’s particular environment by adhering to these suggestions.
What Are The Common Issues With Plants Growing in Wisconsin?
Several difficulties might arise with growing plants in Wisconsin, including:
Frigid temperatures: Plants that are not hardy enough to endure freezing temperatures may be damaged or killed by Wisconsin’s frigid winters.
Summers that are hot and muggy: The summers that are hot and muggy in Wisconsin can be stressful for some plants, particularly if it does not give them enough water or shade.
Soil: Wisconsin’s soil varies widely by region, with some having soil that is either too acidic or too alkaline for particular plants.
Drought: Wisconsin occasionally experiences droughts, which can stress plants and hinder their ability to flourish.
Flooding: Flooding is a potential issue in some areas of Wisconsin because it can harm or kill plants and wash away soil and nutrients.
Selecting plants that are suitable to your area’s climate and soil and giving them the care and attention they require to thrive will help you overcome these difficulties.
This covers routine fertilization, pruning, watering, and insect control. A local nursery or gardening specialist can provide guidance on the most suitable plants and maintenance methods for your area.
