Step 3: Extract Seeds – The seeds on a strawberry are those tiny little things found on the outside of every strawberry. Take one strawberry, and using a toothpick or knife point, scrape at the seeds to dislodge them and remove them from the fruit. It may be very fiddly to extract them from the fruit depending on the ripeness of the fruit and other factors.
How do you disperse strawberry seeds?
The production of fruit aids in seed dispersal. Strawberry plants are sedentary; therefore, they rely on other organisms to carry their seeds. Many birds and mammals feed on the tasty fruits, allowing the seeds to travel through the digestive system and eventually be excreted.
Can you strain strawberry seeds?
How to Remove the Seeds from Strawberry Puree – If you want an even smoother sauce you can strain out the seeds from your strawberry puree using a fine mesh sieve. Some smaller seeds may sneak through the wholes of the sieve but most of them will be strained out.
Are the seeds on the outside of a strawberry?
Why Do Strawberries Have Their Seeds on the Outside? “Why do strawberries have their seeds on the outside, instead of on the inside?” That was the question one of my daughters asked recently. I had no idea, so I reached out to, an associate professor of horticultural science at NC State.
- And the answer surprised me.
- First off, strawberries don’t keep their seeds outside their fruit.
- Those things we think of as strawberry seeds aren’t seeds – and the big, red strawberry “fruit” isn’t technically a fruit.
- In “true” fruits, like peaches *, a flower is pollinated and then the flower’s ovary swells and becomes the fruit, with the seed or seeds in the middle.
Not so with strawberries. When a strawberry flower is pollinated, the fruit doesn’t swell. The fertilized ovaries in the flower form separate, small, dry fruits. Those “seeds” on the outside of a strawberry are actually the fruits, each of which contains a single seed.
The ripe, red, fleshy part that we think of as the strawberry “fruit” is actually swollen receptacle tissue – the part of the plant that connected the flower to the stem. When a strawberry flower is pollinated, it triggers the receptacle tissue to grow and change. But that still doesn’t answer the question, it just changes it a little.
Why are the small, dry fruits located on the outside of the red, sweet thing that we all like to eat? The short answer is that we don’t really know which evolutionary forces caused the strawberry to develop the way that it did. However, Gunter notes, “there are a few fundamental reasons why plants have evolved different kinds of fruits.
One reason is to attract something that spreads seeds.” A good example is, Scientists believe the avocado, with its enormous wood-like seed, evolved to be eaten that lived thousands of years ago. One of these animals would chow down on some avocados and either leave partially-eaten fruit (and its seed) nearby, or the seed would pass all the way through the animal and be left behind in its waste.
Since those giant beasts are no longer with us, avocados are now dependent on human intervention to spread their seeds. “A second evolutionary approach is for plants to find ways for their fruit to disperse on their own,” Gunter says. “For example, they may fly in the wind, like a dandelion, or be moved by the water, like a coconut.” The third option is for a plant to find ways for a fruit to deter animals from eating it.
- For example, the gingko fruit smells putrid,” Gunter says.
- The goal there is for the fruit to not get eaten, so that the seed can rely on the fruit’s nutrients to support its growth.” Presumably, the strawberry went for evolutionary option number one – attract something to spread the seeds.
- But we don’t know the specifics.
*Note: The example for a true fruit was originally an apple. And then someone told me that apples are not true fruits either. In fact, they belong to a group called pseudo-carps, or false fruits. That’s because the part we think of as the fruit is made from plant parts other than the ovary.
What are the little black seeds on strawberries?
Black seed disease of Strawberry The fungal pathogen that causes the disease called leaf spot does not infect only the foliage of strawberry. On fruit the symptoms of leaf spot are often referred to as black seed disease. The initial symptom is black seed, next the tissue around the seed (receptacle tissue) becomes infected and turns brown. Affected seed occur singly or in groups.
See the for more information about this disease and its management.

How do you get the best out of strawberry plants?
Sowing alpine strawberries indoors – While summer-fruiting and perpetual strawberries are only grown from runners or young plants, alpine strawberries can also be grown from seed indoors, although germination can be slow and unreliable:
Sow either in autumn or spring, into small pots or trays filled with John Innes No.1 or fine seed compost. Firm the compost gently, then scatter the seeds thinly and evenly over the surface and lightly cover with sharp sand Place a clear plastic bag or sheet of glass over the pot or tray to maintain humidity and shade until germination. Autumn-sown seeds should be overwintered in a cold frame Germination requires 18–21°C (65–70°F) and can be slow and erratic As soon as the seedlings have two true leaves and are big enough to handle, prick them out 2.5cm (1in) apart Plant out in May, into a sunny or lightly shaded spot, in the ground or in a container
