Spring Indoor Seed-starting Guide
How to use the chart below: First, estimate the date
your last spring frost is expected using the range of
dates indicated on the map on above. Record the
frost-free date it indicates for your region in the
blank space provided below these instructions.
Next, get a calendar and, for each crop, add or
subtract the number of weeks in column two, “Safe
setting-out time,” from your frost-free date. Record
these dates in the blank spaces under column
three, “Setting-out date.” This is the date it should
be safe to plant your seedlings outside.
(Remember to harden them off for a week or so
before planting them out.) Now, take each date
from column three, subtract the number of weeks
shown for that crop in column four, “From sowing
to setting-out,” and record that date in column five,
“Start indoors date.” That is the latest you should
start those seeds indoors.

The spring frost-free date in my garden is ___________ (based on the map above).
Safe setting-out time From Start
Fruits & relative to Setting-out sowing indoors
Veggies frost-free date date to setting-out date Seed-starting tips
Broccoli 2 weeks before _______ 4 to 6 weeks _______ Choose an early variety for your indoor planting
Cabbage 4 weeks before _______ 4 to 6 _______ Plant thinly; keep cool
Cantaloupe 2 weeks after _______ 3 to 4 _______ Presprout in a paper towel at 80 degrees and then plant carefully
in a 4-inch pot. Not a good candidate for starting in flats
Cauliflower 2 weeks before _______ 4 to 6 _______ Keep cauliflower growing steadily to ensure good heads
Cucumber 1 to 2 weeks after _______ 3 to 4 _______ Root often emerges first
Eggplant 2 to 3 weeks after _______ 8 to10 _______ Can presprout; do not withhold water while hardening off
Leek 4 weeks before _______ 6 to 8 _______ Plant out in trenches
Lettuce 3 to 4 weeks before _______ 4 to 5 _______ Cover seeds thinly, and thin to 3 inches apart in the flat
Okra 2 to 4 weeks after _______ 4 to 6 _______ Soak fresh seeds to soften coat; use deep pots for taproots
Onion 4 weeks before _______ 6 to 8 _______ Use fresh seed, start early and keep at less than 70 degrees
Pepper 2 weeks after _______ 6 to 14 _______ Keep soil on the dry side
Tomato 1 to 2 weeks after _______ 6 to 8 _______ Transplant twice, from starting flat to cell-pack, to 3-inch pots
Herbs
Basil 1 week after _______ 6 _______ Cover only lightly with fine soil
Chives 1 week after _______ 8 _______ Use fresh seed
Lemon balm 3 weeks before _______ 8 _______ Do not cover; needs light to germinate; protect from heavy frost
Parsley 3 weeks before _______ 9 to 10 _______ Presoak seed twice to speed up germination
Sage 1 week before _______ 8 _______ Keep seedlings dry
Thyme 2 weeks before _______ 8 to 10 _______ Keep soil surface dry
Flowers
Ageratum 1 week after _______ 4 _______ Do not cover; needs light to germinate
Dahlia 2 weeks after _______ 8 _______ Save tubers in fall, store in peat moss in a cold, protected place
Marigold 2 weeks after _______ 6 to 8 _______ Tall varieties and hybrids bloom earlier if started indoors
Nicotiana 2 weeks after _______ 6 to 8 _______ Do not cover; needs light to germinate; bottom water
Petunia 2 weeks after _______ 10 to 12 _______ Do not cover; needs light to germinate; bottom water
Snapdragon 1 week after _______ 10 to 12 _______ Do not cover; needs light to germinate; bottom water
Zinnia 2 weeks after _______ 6 to 8 _______ Touchy about transplanting; keep water off leaves to prevent fungus
All of the above, with the exception of slow growers such as eggplant and peppers, can be direct-sown in the garden. If you start them indoors,
you gain an earlier and sometimes better harvest. Start most seeds in a warm location (70 to 80 degrees) but move to a cooler location
(60 to 65 degrees) as soon as they sprout. Be sure all have adequate light
I found this on Motherearth news and thought it was a handy little chart
