Why don’t we grow strawberries from seed? (1)

Virtually all strawberry plants grown to produce fruit were planted as a transplant. Transplants take on many forms, but in California we use bareroot transplants (Fig. 1).

Why not use seeds instead? Those little things on the outside of every strawberry fruit are seeds encased in a hard outer coating (Fig. 2.). They are technically “achenes” but “seeds” will do for now.

If you plant seeds from a strawberry fruit, some of them will germinate, but very slowly. Under optimum conditions it takes about three weeks for the seed to germinate. The seedling that emerges is a tiny plant (Fig. 3). It takes another week to see the first true leaves (Fig. 4) and you’re still looking at a very tiny plant that is months away from producing a flower.

Contrast that to the bareroot transplant, which will push out a new set of leaves immediately after planting (Fig. 4) and produce flowers within days. A flower will take about five weeks to develop into a ripe fruit.

So time is a big factor. If you planted seeds, it would take a year to get a decent sized plant that could produce fruit. That’s too long. The transplant will do it in 2-3 months.

Size is another factor. How would you plant that tiny seed and nurse it to maturity in a field setting? Tiny strawberry seeds and seedlings have to be babied along until they are large and robust enough to survive outdoor conditions.

When we grew our first crop of strawberries at Cal Poly, I wondered why we didn’t see volunteer strawberries in that field when we grew a subsequent crop. After all, thousands of fruit that didn’t get picked ended up rotting and the seeds ended up in the soil. Wouldn’t these all germinate and give rise to a lawn of tiny strawberry plants once the field was irrigated again? That’s what happens if you let weeds or any other crop go to seed the previous season. With strawberries, most of the seeds don’t end up in an environment where they can survive the journey from seed to mature plant, but if you look closely enough you will find volunteer strawberry plants, just not very many.

And lastly is the genetics piece. Bareroot transplants are actually daughter plants that are clones (genetically identical) of the mother plant. Seeds are produced by the exchange of genetic information from two parents. And since strawberries are a hybrid (Fragaria x ananassa) you’re going to get a lot of variation in the progeny or offspring. We don’t want that variation because a lot of it will turn out to be inferior in some way. The beauty of clonally propagated plants is that once you have the traits you desire most, the daughter plants will all have the same traits and this leads to higher and more uniform productivity.

And that’s why we don’t farm strawberries by starting with seeds. On the other hand, strawberry breeders work with seeds because they are deliberately crossing specific parents to produce progeny that have specific, desirable traits. In order to get new individuals with unique traits, you have to introduce new genes from new parents.

Why don’t we grow strawberries from seed? ›

Growing strawberries from seed? Yes, it's possible! A strawberry patch is usually started from young plants or dormant root clumps, but you can grow delightful berries from seed too. Seed-started plants typically bear smaller fruit than hybrid varieties that are available exclusively as plants.

As some research indicates many or most shop bought strawberries are special hybrids where the seeds may never grow strawberries!

Why won't my strawberry seeds grow? ›

Keep the soil moist well-lighted. Warmth can help the seeds germinate, so the top of a refrigerator or on a bottom heat pad can be suitable places for germination. If the strawberry plant seedlings aren't in direct sunlight with supplemental light, consider providing additional artificial light.

Can you pick the seeds off a strawberry and plant them? ›

When you're looking for strawberries to replant, buy fruit that's plump and free from bruises and discoloration. Slice the strawberries in half and leave them on a paper towel to dry. This allows the tiny seeds to become detached from the fruit and easily scraped away from the berry.

Do they make strawberries without seeds? ›

Traditional strawberries have small, hard seeds that grow on the outer surface of the fruit. Seedless strawberries, on the other hand, have been bred to be hollow in the center, which means that they don't have the small seeds that traditional strawberries have.

Do strawberry plants come back every year? ›

Properly cared-for strawberries come back year after year. Daughter plants replace the originals as you renovate the bed. However, due to a drop in production, most gardeners renew their June-bearing strawberry patch after three to five years or their everbearing patch every other year.

Can I grow strawberries from strawberry tops? ›

We offer many tips on kitchen scrap gardening, so you may be asking, “can I regrow strawberries from strawberry tops?” The short answer is, no. Strawberry plants can't propagate. But you can grow this other favorite fruit from scraps!

How long does it take strawberries to grow from seed? ›

You've probably wondered how long does it take for Strawberries to grow. On average, it takes 60 to 90 days for a plant to mature from a seed to a delicious berry. The duration of the developing phase depends on the growing conditions you create.

What is the paper towel method for strawberries? ›

Just like with the lettuce, once you bring your berries home, open the container, place a paper towel over top of them, and store them in the fridge upside down. Make sure to wash the berries when you're ready to eat them but don't wash the whole container before storing as that adds extra unwanted moisture.
