When Buying Seeds in Bulk Saves Money (and When It Doesn’t)

It’s seed buying season, and if you’re like many gardeners, you’ve probably spent time flipping through seed catalogs, dreaming about what to grow this year. But when it comes to buying seeds, there’s a way to save money that you might not have realized — bulk buying, even for the home gardener.

We buy seed packets by default. Seed packets are what we see in the stores; they are what we have purchased for years, and most of us are not market gardeners. We assume a packet is always the most practical option for a home garden. In reality, that assumption can cost you money. In this post, I’ll walk you through when buying seeds in larger quantities actually makes sense, when it doesn’t, and how to choose the right option for your garden and the crops you plan to grow.

The Seed Buying Blind Spot

Whether you are buying seeds at a local store, from catalogs, or at on online store, our habit is usually the same. We grab seed packets and move on. We assume a seed packet is designed for the home gardener, and there will be plenty of seeds in each packet. While that is true for some crops, there are several crops where buying the seeds in bulk makes the most sense.

What many gardeners don’t realize is that “bulk” doesn’t mean farmer-sized quantities. Many seed companies offer a next-size-up option that is still manageable for home gardeners. These slightly larger quantities often cost far less per seed, even though the upfront price is higher. Sometimes saving money means sizing up. Other times, it actually means sizing down.

Why Seed Packet Prices Vary So Much

If you’ve ever compared seed catalogs, you’ve probably noticed how different prices can be for similar crops. One company’s packet might be $6–$7, another might be $2.50–$3, and another might fall somewhere in the middle. The difference is often not quality. It’s usually quantity.

Not all seed packets contain the same number of seeds, which means comparing packet prices alone can be misleading. To find the best value, it helps to look at the cost per seed, gram, or ounce—especially when you’re deciding whether to move up to the next size. You can do the math by hand, but if you want to save time, tools like ChatGPT can quickly calculate the cost per seed or weight so you can make a smarter decision without the extra work.

Which Crops Are Worth Buying in Larger Quantities?

A helpful way to decide is by asking yourself a few simple questions to help you determine when it makes sense to purchase your seeds in larger quantities.

Near the end of this article, I have shared the names (and links) of online seed companies that I routinely order from that offer seeds in large quantities. I trust each of these sellers and love growing crops from all of them.

How Many Plants Will You Actually Need?

Some garden crops, like tomatoes and peppers, can produce a steady harvest for months from just a few plants. Other crops, especially leafy greens and shelling crops, produce much less per seed planted. Those low-yield-per-seed crops are often the best place to start when deciding which seeds may be worth buying in larger quantities.

Spinach is a great example. If you’re growing baby spinach for fresh salads, a small packet may be enough. But if you want spinach you can actually cook, you’ll need far more plants than you might expect. Spinach cooks down quickly, and it takes a lot of leaves to make even a small serving.

Shelling peas and shelling beans fall into this same category. If you’re growing peas to shell or beans to dry for storage, it takes a lot of plants to get a harvest that feels worthwhile. Small seed packets often don’t go nearly as far as they look like they will.

I’ve made this mistake myself. In the past, I bought a packet of shelling bean seeds, thinking it would cover what I had planned. After I started sowing the seeds, I realized one seed packet barely planted a single row. This experience helped me start paying closer attention to seed quantities.

Other crops that often make sense to size up for this situation include:

1. Arugula
2. Mesclun and lettuce mixes
3. Brassica greens mixes
4. Collard greens

These are crops where you typically need many plants or repeated sowings because one plant will only yield a few leaves or a small number of pods.

Scatter Sowing and Succession Sowing Matter

The next question to ask is how you plant.

Scatter sowing is common with greens. Instead of placing one seed in one hole, you spread seeds across an area and harvest them young. This naturally uses more seed.

Succession sowing means planting the same crop multiple times throughout the season. Arugula is a great example because it can be planted every few weeks. Bush beans and peas are also commonly succession planted.

If you scatter sow or succession sow a crop, buying a larger quantity often makes more sense than repeatedly buying small packets.

Why Having Backup Seed Is Helpful

Another important consideration is whether you need backup seed. Things go wrong in the garden. Seeds may not germinate if the soil is too cold. Pests may eat young seedlings. Weather swings can damage plants.

If you use all your seed in one planting and something goes wrong, you may need to reorder and pay shipping again. Having extra seed on hand makes it easier to replant without stress. This is especially helpful for crops like beans, peas, and greens that are quick to replant.

Spring and Fall Planting Changes the Equation

Many cool-season crops are planted more than once a year. Spinach, lettuce, arugula, collards, and peas can all be planted in spring and again in fall. If you know you want to grow these crops in both seasons, buying enough seed upfront can make sense and save you money (and the cost of shipping if you make multiple orders). This also encourages planning ahead for fall gardening, which often gets overlooked but can be incredibly productive and rewarding.

Cover Crops Are an Easy “Yes”

If you grow cover crops, buying in larger quantities almost always makes sense. Cover crops are scatter sown over large areas, and small packets rarely match bed sizes. Larger quantities offer better coverage, lower cost per square foot, and less frustration.

Do Seeds Store Well?

When buying seeds in bulk, it’s also important to consider how well they store. The good news is that most garden seeds will last for multiple seasons when they’re kept cool, dry, and out of direct light. Seeds like beans, peas, arugula, salad greens, and even cover crops often stay viable for several years. In fact, I am still successfully planting some bean and cover crop seed that are a few seasons old. Most of the crops that benefit from larger quantities are good long-term keepers.

Not all seeds store equally well, though. Onion seed is one example that tends to have a shorter shelf life. While onion seed may last a season or two, it is less reliable long-term, and it is not a crop I would suggest buying in bulk. Keeping storage life in mind helps you decide which seeds are safe to buy in larger quantities and which ones are better purchased fresh each year.

Crops That Usually Do Not Make Sense to Buy in Bulk

Not everything should be bought in larger quantities. For most home gardeners, it usually does not make sense to buy bulk amounts of:

1. Tomatoes
2. Peppers
3. Broccoli
4. Cabbage
5. Cauliflower

These crops typically produce a large harvest from a single plant. One seed equals one plant, and you usually don’t need many plants of the same variety.

These are also crops where many gardeners like to experiment with different varieties. Smaller packets make it easier to test what grows well in your garden without committing to a large quantity.

Sometimes Sizing Down Is the Smarter Choice

There are times when buying smaller packets actually makes more sense. If you want to try multiple varieties, test a new crop, or experiment with disease or heat resistance, smaller quantities give you flexibility. You may pay more per seed, but you gain variety and reduce waste.

Trusted Seed Suppliers Who Offer Larger Seed Quantities

Below is a list of several online seed retailers where I have purchased seed in larger quantities.

• Johnny’s Selected Seeds
• Territorial Seed Company
• True Leaf Market

Trusted Seed Suppliers Who Offer Less Expensive Options

If you don’t want to buy in bulk, but you want to try different varieties for less cost per seed packet, here are my favorite sources:

• Botanical Interests – Use coupon code JOURNEYWITHJILL for 5% off your order

A Simple Way to Approach Seed Buying This Year

You don’t need to change everything at once. Consider the discussion above, and choose one to three crops you grow every year that you will need more seed for, and compare the packet price to the next size up. For crops you’re testing or experimenting with, consider whether a smaller packet fits your goals better.

This simple shift can help you spend less over time, waste less, and feel more confident throughout the season. You may need to spend a little more up front, but the bulk seeds will last for several seasons. The exact prices will change over time, but the takeaway is this: for crops you grow that use a lot of seed, comparing the packet to the next size up is often worth your time when buying seeds in bulk.
