The Complete Spring Planting Guide: Early Varieties, Succession Planting & Seed Saving

Your Guide to a Successful Spring Garden

Hey there, gardeners — Grizz here.

Spring is just around the corner, and if you're anything like me, you're already itching to get your hands in the soil. But here's the thing: successful spring gardening starts with knowing what to plant and when to plant it.

This comprehensive guide will walk you through everything you need to know about early spring planting, from selecting cold-hardy varieties to building a succession planting schedule that keeps your harvests coming all season long.

Understanding Your Spring Planting Windows

Not all spring vegetables are created equal. Some thrive in the cool soil of early spring, while others need warmer conditions. Here's how to think about your planting timeline:

Early Spring (4-6 weeks before last frost)

These cold-hardy champions can handle frost and actually prefer cooler temperatures:

• Lettuce & Salad Greens - Plant as soon as soil can be worked
• Spinach - Extremely cold-tolerant, one of the first crops to plant
• Peas - Both snap and shelling varieties love cool weather
• Brassicas - Broccoli, cabbage, kale, and cauliflower transplants
• Radishes - Quick-growing and perfect for succession planting
• Onions & Leeks - Start from sets or transplants

Mid-Spring (2-3 weeks before last frost)

These crops tolerate light frost but prefer slightly warmer soil:

• Carrots - Direct sow when soil reaches 45°F
• Beets - Both roots and greens are delicious
• Swiss Chard - Incredibly productive and beautiful
• Turnips - Fast-growing dual-purpose crop

Late Spring (after last frost)

Wait for these warm-season crops until all danger of frost has passed:

• Tomatoes - Transplant when nighttime temps stay above 50°F
• Peppers - Need warm soil and air temperatures
• Beans - Direct sow when soil reaches 60°F
• Squash & Cucumbers - Heat lovers that won't tolerate frost

Why Heirloom Seeds Matter for Spring Planting

When you choose open-pollinated heirloom varieties, you're not just planting seeds — you're participating in a living tradition of seed saving and biodiversity preservation.

Here's what makes heirlooms special for spring gardening:

• Adaptation - Heirloom varieties adapt to your specific growing conditions over time. Save seeds from your best plants, and each generation becomes better suited to your garden.
• Flavor - These varieties were selected for taste, not shipping durability. The difference is remarkable.
• Biodiversity - Every heirloom variety preserved is a genetic resource protected for future generations.
• Seed Sovereignty - You can save seeds and never need to buy that variety again.

Mastering Succession Planting

One of the biggest mistakes new gardeners make is planting everything at once. The result? A massive harvest you can't possibly use, followed by weeks of nothing.

Succession planting solves this problem by staggering your sowings for continuous harvests.

The Basic Strategy

For quick-maturing crops like lettuce, radishes, and beans, plant small amounts every 2-3 weeks throughout the season. This ensures you always have fresh produce at the perfect stage.

Succession Planting Calendar Example

Lettuce:

• Week 1 (early spring): Plant first succession
• Week 3: Plant second succession
• Week 5: Plant third succession
• Continue every 2 weeks through early summer
• Resume in late summer for fall harvests

Radishes:

• Plant every 10-14 days from early spring through late spring
• Skip the heat of summer
• Resume in late summer for fall crops

Seed Saving Basics for Spring Crops

Spring is the perfect time to start thinking about seed saving. Here are some beginner-friendly crops to start with:

Easy Spring Seed Saving Crops

Lettuce - Allow a few plants to bolt and flower. Collect seeds when dry and fluffy. Self-pollinating, so varieties stay true.

Peas - Leave pods on the vine until completely dry and brown. Shell out seeds and store. Self-pollinating.

Radishes - Allow plants to flower and form seed pods. Harvest when pods are dry and tan. Can cross-pollinate, so isolate varieties.

Spinach - Separate male and female plants. Save seeds from the best female plants when seed heads are dry.

Seed Saving Tips

• Always save seeds from your healthiest, most productive plants
• Allow seeds to fully mature and dry on the plant when possible
• Store seeds in a cool, dry, dark location
• Label everything with variety name and year saved
• Test germination rates before the next planting season

Building Your Spring Planting Plan

Here's a simple framework to create your own spring planting schedule:

1. Know your last frost date - This is your anchor point for all spring planting
2. Map your garden space - Decide what goes where based on sun, space, and succession needs
3. Choose your varieties - Select heirloom varieties suited to your climate and taste preferences
4. Create a planting calendar - Work backward from your last frost date
5. Plan for succession - Build in multiple plantings of quick-maturing crops
6. Prepare for seed saving - Identify which crops you'll save seeds from this season

Essential Spring Planting Tips

• Don't rush warm-season crops - Planting tomatoes too early just stresses them. Wait for proper soil temperatures.
• Prepare soil in fall - Spring soil prep is easier when you've added compost and amendments the previous fall
• Use row covers - Extend your season and protect early plantings from unexpected cold snaps
• Keep records - Note what you planted, when, and how it performed. This data is gold for future seasons.
• Start small - Better to succeed with a small, well-managed garden than be overwhelmed by too much space

Start with the basics, choose varieties that excite you, and don't be afraid to experiment. Every season teaches you something new.

Here's to a bountiful spring harvest!
