(Why I’m Taking You from Radish to Celery, And Why It Will Change How You Garden Forever)
Welcome to the most practical, no-BS seed-starting series you’ll ever read.
If you’ve ever:
Bought a packet of seeds and watched nothing happen
Ended up with tall, floppy tomato seedlings that barely produced
Given up on onions because “they never sprout for me.”
Felt overwhelmed by conflicting advice online
…then this series is built specifically for you.
Over the next 10 weeks (plus one epic bonus cheat-sheet post), I’m going to walk you through starting the most common vegetables from seed, in perfect order from dead-easy to expert-level gardener!
We start with crops that germinate in days and forgive every mistake. We end with the two vegetables that will make you question your life choices (onions and celery).
By the time you finish Post #10, you will have:
Mastered every major seed-starting skill (surface sowing, heat mats, potting up, humidity domes, baggie methods, and more)
Built absolute confidence, because you’ll have practiced each technique on easier crops first
Grown (or be ready to grow) every vegetable on the list successfully
Saved hundreds of dollars on transplants
Turned “I have a black thumb” into “Look what I grew from a tiny seed!”

How This Series Is Different
Most seed-starting guides dump everything on you at once: “Here’s a list of 50 vegetables and some vague dates.” That’s overwhelming and sets you up to fail.
Instead, we’re doing this like a video game with progressive levels:
Post # | Difficulty | Vegetables Covered | What You’ll Master This Week |
1 | Easiest | Radish + Arugula | Instant gratification, thinning, direct vs. indoor |
2 | Very Easy | Lettuce & Spinach | Constant moisture, domes, true leaves |
3 | Easy | Kale, Collards, Swiss Chard, Asian Greens | Potting up, cold tolerance, continuous harvest |
4 | Easy-Mod | Beans & Peas | Direct sowing large seeds, trellising, inoculants. |
5 | Moderate | Cucumbers, Zucchini, Summer Squash, Melons | Heat mats, damping-off prevention, pollination. |
6 | Moderate | Tomatoes | Deep potting up, light distance, pruning basics |
7 | Mod-Hard | Peppers & Eggplant | Double heat mats, extreme patience |
8 | Hard | Broccoli, Cabbage, Cauliflower, Brussels | Long indoor period, cool growing, calcium needs |
9 | Very Hard | Onions, Leeks, Bunching Onions, Chives | Surface sowing, baggie method, fresh seed only |
10 | Expert | Celery & Celeriac | 100 % humidity, gauze trick, monk-level devotion |
Each post is a deep dive packed with:
Step-by-step instructions (with two methods when possible)
My personal variety recommendations
Pro tips that actually move the needle
Troubleshooting charts you’ll refer to forever
The exact skills that prepare you for the next, harder crop
After Post #10, I’ll drop the ultimate bonus: a printable one-page cheat sheet plus expanded calendars, gear lists, and zone-specific timing, your permanent garden bible.
Who This Series Is For?
Absolute beginners who want to start right and avoid years of frustration.
Intermediate gardeners tired of leggy tomatoes and failed onions.
Anyone who wants to grow more food for less money.
Parents teaching kids (radish and beans are pure magic for little hands).
Balcony and container growers (everything here works in pots).
You do NOT need a greenhouse, fancy lights (though I’ll tell you when they help), or decades of experience.
You just need to follow along, one post at a time.
What You’ll Need to Get Started
Basic kit for the whole series (under $100 if you shop smart):
Seed trays or recycled containers
Clear domes or plastic wrap
Good seed-starting mix
A warm spot (and later, a heat mat)
Lights (shop light or sunny window to start)
Fresh seeds from reputable companies (I’ll share my favorites)
I’ll remind you what to add as we level up.

Let’s Make a Promise
If you read each post and start at least one packet of seeds from that week’s crop, I guarantee two things by the end:
You will have eaten something you grew from seed.
You will never again be intimidated by a seed packet.
We start next week with Post #1: Radish, the impossible-to-kill confidence builder.
See you in Post #1.
Let’s grow.🥦
