Learn the Best Time to Plant Seeds in Your Garden
One of the most common questions gardeners ask is simple: When should I plant?
The answer depends on where you live. Your climate, frost dates, and USDA Plant Hardiness Zone all determine the right time to start seeds indoors or sow directly outdoors.
Every Page Seed packet includes zone-based planting information to help you plant at the right time for your area. This guide explains how to use that information so you can feel confident knowing when to begin.
Find Your USDA Planting Zone
When your frost dates occur
When to start seeds indoors
When it’s safe to plant outside
Which crops grow best in your climate
Use the map to locate your zone, or check online by entering your ZIP code into any USDA zone lookup tool.
How to Use the Planting Information on Your Packet
Every Page Seed packet includes guidance such as:
“Start indoors X weeks before last frost”
“Sow outdoors after all danger of frost”
“Plant in early spring”
“Best for cool-season planting”
Because each variety is different, your packet is the most accurate source for timing. The steps below help you understand how to use that timing information with your zone.
Step 1: Know Your Frost Dates
Your last frost date (spring) tells you when it’s safe to plant warm-season crops outdoors.
Your first frost date (fall) tells you how long your growing season lasts.
Warm-season vegetables like tomatoes and peppers must be planted after your last frost.
Cool-season crops like lettuce and peas can be planted before or after, depending on your zone.
Step 2: Decide Whether to Start Indoors or Outdoors
Your Page Seed packet will specify this. In general:
Start indoors: tomatoes, peppers, broccoli, cabbage, cauliflower.
Sow directly: beans, peas, carrots, cucumbers, squash
Indoor starting gives you a head start, especially in zones with shorter growing seasons.
Step 3: Count Back from Your Last Frost Date
If your packet says:
“Start indoors 6-8 weeks before last frost”
and your last frost is May 10,
then start indoors between March 15 and April 1.
This is the simplest and most reliable method for timing.
Step 4: Follow Seasonal Recommendations
Cool-Season Planting (Spring & Fall)
Lettuce
Kale
Spinach
Peas
Radishes
Warm-Season Planting
(Late Spring & Summer)
Tomatoes
Peppers
Beans
Squash
Cucumbers
Step 5: Adjust for Microclimates
Even within the same zone, gardens vary. Your planting may differ slightly if you have:
A warm south-facing wall
Shaded areas
Wind-exposed spots
Raised beds that warm earlier in spring
Use the zone map as your starting point, then adjust based on your actual conditions.
Why Planting at the Right Time Matters
Planting too early or too late is one of the most common gardening mistakes. Correct timing helps you:
Improve germination
Reduce plant stress
Avoid frost damage
Get bigger harvests
Grow healthier, more productive plants
Your packet + your zone = a planting plan tailored to your garden.
