When Should I Start Spring Landscaping and Planting in Northern Indiana?

The first signs of spring in Indiana are always exciting. After months of gray skies and frigid temperatures, the snow begins to melt, and the sun starts shining a little longer each day. Naturally, you can’t wait to get outside, rolling up your sleeves to refresh your landscape and get your garden blooming. But before you grab those gardening gloves, there’s one critical question to answer—when’s the right time to start?  

At Shelton Landscape Group, we’ve been guiding homeowners and businesses through the dos and don’ts of spring landscaping for years. We know how crucial timing is, especially in a climate as unpredictable as Northern Indiana’s. That’s why we’re here to share everything you need to know to make sure your spring landscaping turns into a thriving success.

Why Starting Too Early Can Be Harmful

It’s tempting to begin landscaping the moment the snow clears away. However, starting too early may backfire. Cold temperatures and unexpected frosts can wreak havoc on your plants.  

When temperatures drop below freezing, the water inside plant tissues freezes, damaging their cells and vascular systems. This type of frost damage can lead to weak growth—or, even worse—kill entire plants. While frost may seem harmless to hardy greenery, a “killing freeze” (when temperatures fall below 28°F) can cause irreversible harm. That’s why knowing when to plant is critical to protecting your investment.

When’s the Best Time to Start Planting?

Spring in Northern Indiana is unpredictable, especially when it comes to freeze patterns, making it crucial to time your planting carefully. Frost and freeze warnings typically persist through late April, with the “average last freeze” occurring during the final weeks of the month. However, colder temperatures can linger into early May, and on rare occasions, unexpected frosts have been known to appear as late as June. A good rule of thumb for planting is to wait until after Easter to start moving plants outdoors, but for those wanting to play it safe, many gardeners recommend holding off until after Mother’s Day in mid-May. This ensures your delicate plants are protected from any lingering cold snaps.

Get a Jump on Spring with These Early Landscaping Tips

Even if planting is off the table until May, that doesn’t mean you can’t get a head start on your landscaping efforts. Starting preparations early will ensure you’re ready to go as soon as the weather permits.

1. Start Seeds Indoors

Beginning your plants indoors is a great way to give them a head start while avoiding unpredictable outdoor conditions.  

• Use small seedling trays with soil tailored to your plants’ needs.  
• Position the trays near a south-facing window for optimal sunlight.  
• When the threat of frost has passed, transplant your seedlings into your garden beds.  

2. Prepare Soil and Garden Beds

• Test your soil for pH and nutrient levels. This will help you determine whether you need to add fertilizer or adjust acidity levels.  
• Remove weeds, debris, and any remnants of last year’s plantings.  
• Work compost or organic matter into the soil to enrich it ahead of planting.  

3. Choose Early Spring Planting Options

While most flowers and crops can’t be planted until late April or May, certain hardy plants thrive in cooler conditions. Consider starting with these frost-tolerant options:

• Vegetables like spinach, kale, and radishes.
• Flowers like pansies and snapdragons.
