The garden center is a wonderful and dangerous place. There are seeds in little packets for seventy-nine cents, and there are seedlings in little pots for four dollars each, and nobody is explaining why one costs five times more than the other or which one Tom Brownthumb should be reaching for.
Here’s the honest answer: both are right, depending on what you’re growing, when you’re growing it, and how much patience you have on any given Tuesday in April.
The fundamental difference: seeds are the beginning of the story. Seedlings are the story already several chapters in. You’re either starting from scratch or buying yourself some time.
🌰 The Case for Seeds
Seeds are cheap. Absurdly cheap compared to seedlings. A packet of tomato seeds costs less than a single tomato plant and contains enough seeds to start a small operation. For anyone growing multiples of the same thing — sunflowers, beans, zucchini, lettuce — seeds are the obvious economic choice.
When seeds make sense: plants that don’t like being transplanted are always better started from seed directly in the ground. Carrots, beans, peas, radishes, and most root vegetables develop tap roots that object strenuously to being moved. Plant these kind of plants in the space where they’re going to live.
Seeds also give you access to varieties the garden center never carries. The garden center stocks twelve tomato varieties. Seed catalogs stock hundreds. If you have opinions about tomatoes — and eventually you will — seeds are where those opinions get expressed.
The tradeoff: time. Seeds need weeks to become plants. Some need to be started indoors before the last frost date. There is a calendar involved and it has opinions.
🌿 The Case for Seedlings
Seedlings are time already purchased. Someone else did the germination work, the thinning, the early watering, the careful temperature management. You are paying for those weeks, and sometimes those weeks are worth the money.
When seedlings make sense: plants with long growing seasons — tomatoes, peppers, eggplant — need so many weeks to mature that starting from seed outdoors isn’t practical in most climates. Unless you’re starting seeds indoors in February, you’re buying seedlings.
Seedlings are also the right choice when you only want one or two plants. Buying a packet of twenty-five pepper seeds to grow two peppers is wasteful. Buy two pepper seedlings and call it done.
The tradeoff: cost, and transplant shock. Every seedling goes through a period of adjustment after it moves from the garden center to your soil. It will look terrible for a week. This is normal. See our post on transplant shock.
🗓️ The Quick Reference
- Start from seed: beans, peas, carrots, radishes, beets, sunflowers, zucchini, cucumbers, lettuce, spinach.
- Buy as seedlings: tomatoes, peppers, eggplant, broccoli, cauliflower, celery — anything with a long season that needs a head start.
- Either works: basil, kale, chard, most herbs, marigolds, nasturtiums. Pick whichever makes more sense for your budget and timeline.
🛒 Worth Having
- Seed starting tray with dome — For starting seeds indoors. The dome holds humidity while seeds germinate. Remove it once seedlings appear.
- Seed starting mix — Not the same as potting soil. Seed starting mix is finer, lighter, and designed for germination. Seeds started in regular soil struggle.
- Plant markers — Label everything immediately. All seedlings look identical at two inches tall and you will not remember what you planted where. This is a promise.
- Seed storage organizer — For the seeds you don’t use this season. Stored cool and dry, most seeds remain viable for two to three years.

✨ The Short Version
Seeds for direct-sow plants and budget-conscious gardeners with patience. Seedlings for long-season plants and anyone who would like something to actually happen this year.
Neither choice is wrong. Both choices involve some dirt under the fingernails eventually.
Wicket doesn’t care which one you pick. Wicket just wants you to put something in the ground.
