Spring Timeline at a Glance

The work breaks into phases keyed to your last frost date. Use this card to see where each major task falls, then dig into the detailed checklists below.

When to do what

Early Spring

6-8 weeks before last frost: order seeds, plan, start cold-hardy transplants

Mid-Spring

4-6 weeks before last frost: soil prep, season-extension structures, warm-season seeds

Late Spring

2-4 weeks before last frost: transplant cool-season crops, harden off, install supports

Post-Frost

After last frost: transplant warm-season crops, direct sow heat-lovers, remove covers

Early Spring (6-8 weeks before last frost)

Order seeds and review last year's garden notes
Clean and sharpen garden tools
Check irrigation systems and repair any damage
Plan garden layout and crop rotation schedule
Start cold-hardy seeds indoors: broccoli, lettuce, kale
Order soil amendments and compost
Test soil pH and nutrient levels

Mid-Spring (4-6 weeks before last frost)

Begin soil preparation when ground is workable
Add compost and organic matter to garden beds
Install season extension structures (cold frames, row covers)
Start warm-season seeds indoors: tomatoes, peppers, herbs
Direct sow cold-tolerant crops: peas, radishes, spinach
Prune fruit trees and berry bushes
Apply pre-emergent herbicides for weed control

Late Spring (2-4 weeks before last frost)

Transplant cool-season seedlings to garden
Harden off warm-season transplants
Install trellises and plant supports
Apply mulch to suppress weeds and retain moisture
Set up drip irrigation systems
Plant potatoes and onion sets
Prepare transplant holes with compost

Soil Preparation Essentials

Soil test priority

Test your soil every 2-3 years to monitor pH, nutrient levels, and organic matter content. Most vegetables prefer pH 6.0-7.0 for optimal nutrient uptake.

Soil Improvement Tasks

pH Adjustment: Add lime to raise pH or sulfur to lower it (apply the fall before for spring planting)
Organic Matter: Add 2-4 inches of compost to improve soil structure and fertility
Tillage: Work soil when crumbly, not wet or completely dry
Drainage: Install drainage tiles or create raised beds for poor-draining areas

Seed Starting Schedule

Indoor Seed Starting Timeline

Weeks Before Last Frost	Start Indoors
10-12 weeks	Peppers, eggplant, oregano
6-8 weeks	Tomatoes, basil, cilantro
4-6 weeks	Lettuce, broccoli, cabbage
2-4 weeks	Cucumbers, squash, melons

Tool Maintenance Checklist

Essential Tool Maintenance

Sharpen pruning shears, hoes, and shovels
Oil wooden handles and metal components
Replace worn or damaged tools
Check hoses for leaks and repair connections
Service tiller or lawn mower
Organize and inventory garden supplies
Check seed viability with germination tests

Irrigation System Setup

Spring Irrigation Tasks

System Inspection: Check all lines, emitters, and timers for winter damage
Pressure Testing: Verify proper water pressure throughout the system
Timer Programming: Set seasonal watering schedules based on crop needs
Mulch Application: Apply 2-3 inches around plants to reduce water needs

Crop Rotation Planning

Rotation benefits

Proper crop rotation prevents soil depletion, reduces disease pressure, and naturally improves soil fertility through nitrogen-fixing legumes.

Four-Year Rotation Groups

Year 1 - Brassicas: Broccoli, cabbage, kale, radishes
Year 2 - Legumes: Beans, peas, cover crops
Year 3 - Solanaceae: Tomatoes, peppers, eggplant
Year 4 - Cucurbits/Roots: Cucumbers, squash, carrots

Garden Planning and Record Keeping

Essential Garden Records

Planting Dates: Track actual vs. planned planting times
Variety Performance: Note which varieties performed best
Harvest Yields: Measure production for planning improvements
Problem Areas: Document pest issues, disease problems, poor performers
Weather Data: Record frost dates, rainfall, extreme temperatures

Early Pest Prevention

Proactive Pest Management

Beneficial Insects: Plant flowers to attract natural predators
Row Covers: Install at planting to prevent pest establishment
Crop Diversity: Interplant to reduce pest concentration
Sanitation: Remove old plant debris harboring pests and diseases

Post-Frost Planting (after last frost date)

Transplant warm-season crops: tomatoes, peppers, basil
Direct sow heat-loving crops: beans, cucumbers, squash
Remove season extension covers
Begin regular watering schedule
Apply first round of side-dress fertilizer
Start succession planting schedule
Monitor for early pest activity

Spring Preparation Timeline Summary

Week-by-Week Spring Schedule

8 weeks before last frost: Order seeds, plan garden, start cold-hardy transplants
6 weeks before: Soil test, tool maintenance, start warm-season seeds
4 weeks before: Soil preparation, install infrastructure, plant cold crops
2 weeks before: Transplant cool-season crops, harden off transplants
Last frost date: Plant warm-season crops, remove covers
2 weeks after: Complete planting, establish maintenance routines

Success tip

Spring preparation is the most important investment in your garden's success. Take time to complete each task thoroughly. Rushing early steps leads to problems throughout the growing season.
