Growing Strawberries in a Tower Garden: A Complete Guide

Best Strawberry Varieties for a Tower Garden

A strawberry is a strawberry, right? Not quite! Different varieties respond differently to day length and temperature, which helps determine when you'll see flowers—and when you can start watching for berries.

June-bearing or short-day strawberries tend to produce a more concentrated crop when the right conditions trigger flowering. Despite the name, “June-bearing” doesn't mean you should expect a June harvest everywhere!

Day-neutral strawberries are less dependent on day length and can flower and fruit repeatedly while temperatures and other growing conditions stay suitable.

There are also everbearing strawberries, which typically produce more than one crop during their growing season. Sadly, “everbearing” doesn't mean unlimited strawberries forever. We wish!

At Living Towers, we offer two strawberry varieties seasonally: Fronteras and Albion.

How to Plant Strawberries in a Tower Garden

If berries are the goal, starting with an established strawberry plant gives you a much easier head start. You can grow strawberries from seed, but you'll need considerably more patience before those plants reach productive size.

Already have a strawberry seedling growing in rockwool? Place the cube into a regular Tower Garden growing port, just as you would with your other seedlings.

Make sure the rockwool receives water from the Tower Garden and the plant sits securely in its port. A wobbly plant or a dry cube won't give your strawberries the start you're hoping for.

Where to Plant Strawberries in a Tower Garden

Good news: strawberries don't need the cages or trellises that tomatoes and cucumbers often require. They do appreciate plenty of light, good airflow and neighbors that respect their personal space.

Think ahead when planting. That tiny seedling next door might become a leafy giant in a few weeks! Avoid putting strawberries where larger crops will eventually block their light.

As berries develop, they'll naturally hang outside the tower. That keeps them off the ground and makes it easy to keep an eye on your future snacks.

Fronteras can grow quite a leafy canopy, so leave enough room for air and light to move through the plants. A little breathing room now can save you some untangling later.

How Much Light Do Strawberries Need?

If you want berries rather than a lovely collection of leaves, light deserves your attention. Strawberries need plenty of it to support fruit production.

Outdoors, choose a spot where the plants can receive around 8 hours of direct sunlight per day.

Indoors, run Tower Garden grow lights for approximately 14–16 hours per day, followed by complete darkness overnight. Even your strawberry plants need lights-out time!

Keep the grow lights approximately 6–8 inches from the tops of the plants, adjusting their position as your plants grow.

Best Temperature for Growing Strawberries

Strawberries generally prefer things cooler than warm-season crops such as tomatoes and peppers. They aren't usually the plants cheering on the hottest days of summer!

Temperature affects growth, flowering, fruit set and fruit quality. Different varieties respond a little differently, which is another reason to choose a strawberry that suits your growing conditions.

When it gets too warm, you may see plenty of foliage while flowers and berries become scarce. The plant can look busy without producing the harvest you wanted.

Here in South Florida, strawberries are much better suited to the cooler part of the year than the middle of summer. Sometimes the best growing trick is simply planting in the right season.

Water & Nutrients for Hydroponic Strawberries

No special strawberry menu required! Your plants can grow alongside other crops using Tower Garden Mineral Blend.

For established plants, the standard concentration is 20 mL of Mineral Blend A and 20 mL of Mineral Blend B per gallon of water.

For young seedlings, use approximately 10 mL of A and 10 mL of B per gallon. Start them gently while they settle in.

During very hot weather, reducing nutrient strength can help plants cope with heat stress. Depending on conditions, we may use half-strength or even quarter-strength nutrients.

Keep the reservoir at approximately pH 5.5–6.5 and check the water level regularly. Fruiting plants can get surprisingly thirsty as they mature!

Our Tower Garden Nutrients Guide and Tower Garden Water Guide cover the details without making reservoir care feel like a chemistry exam.

Do Strawberries Need Pollination?

Yes! Strawberry flowers are self-fertile, meaning each flower has the parts needed for pollination. But the pollen still needs to move around the flower thoroughly—it doesn't get a free pass just because everything is in one place.

Outdoors, bees, other insects and air movement often lend a hand. Or a wing. 🐝

Indoors, you'll usually need to take over. Unless you have bees visiting your living room, that job belongs to you!

Use a small, soft paintbrush to gently brush around the inside of each open flower, distributing the pollen. Repeat as new flowers open. It only takes a little attention, and no bee costume is required.

For more help with your new pollinator duties, see our hand-pollination guide.

What Should You Do With Strawberry Runners?

Notice a long stem reaching away from your strawberry plant? That's a runner. Your plant is trying to expand the family!

Runners can develop new plants, which is useful if you'd like more strawberries. But growing them also takes energy from the parent plant.

If your main goal is berries, we generally recommend removing excess runners so the plant can put more energy into its crown, flowers and fruit.

Want more plants instead? Allow a healthy runner to develop, root the new plant, and then separate it from the parent once it's established.

Can You Grow Strawberries Indoors?

Yes—you can grow strawberries indoors in a Tower Garden. Picking a berry in your own home is pretty fun, but strawberries ask for more attention than lettuce or basil.

Your two biggest jobs are light and pollination.

Provide approximately 14–16 hours of good grow light each day, followed by complete darkness overnight. Keep the lights close enough to provide adequate intensity, but don't let the foliage grow into them.

Then grab that small, soft paintbrush and help pollinate the open flowers. Indoor strawberries don't have outdoor insects stopping by to do the work for you.

Give the plants some breathing room, too. Good airflow helps, and crowded foliage can trap moisture around the leaves.

Common Problems When Growing Strawberries Hydroponically

Lots of Leaves but No Strawberries

Your plant looks fabulous, but where are the berries? Check light, temperature and variety first, and look for flowers. Once those appear, make sure they're being thoroughly pollinated. A leafy plant doesn't always mean conditions are right for fruit.

Flowers but No Fruit

Flowers are a promising start! If they aren't turning into berries, check pollination first. Temperature stress can also interfere with fruit production, so look at growing conditions before reaching for more nutrients.

Small or Misshapen Strawberries

A lopsided strawberry may be telling you its flower wasn't completely pollinated. Give each open flower a thorough, gentle brushing rather than assuming the plant needs extra minerals.

Yellow Strawberry Leaves

Yellow leaves are a clue, not a complete diagnosis. Check pH, nutrient strength, water quality, roots and temperature. Are just the older leaves changing color, or is the whole plant affected? A little detective work helps you choose the right fix.

Brown or Crispy Leaf Edges

Crispy edges deserve a closer look. Check for heat or other environmental stress, water and nutrient issues, root problems and pest damage. One symptom can have several causes, so investigate before treating.

Plant Producing Lots of Runners

Your strawberry is in family-expansion mode! Runners are normal, but if berries are your priority, remove the extras so the plant isn't spending so much energy making new plants.

Common Strawberry Pests & Diseases

Growing above the ground helps with some of the challenges of soil-grown strawberries, but it doesn't make your plants invisible to pests. Unfortunately, bugs don't always respect your gardening plans.

Keep an eye out for:

• Aphids – Small sap-feeding insects that like tender new growth and the undersides of leaves.
• Spider mites – Tiny pests that can cause stippling, discoloration and declining foliage. Fine webbing may appear as their numbers increase.
• Japanese beetles – Outdoor visitors that may help themselves to strawberry leaves and flowers.
• Powdery mildew – A fungal disease that can leave affected foliage looking white or gray and powdery.

Check underneath the leaves as well as on top. Catching a few unwanted visitors early is much easier than dealing with a whole gathering! Good airflow and regular inspections go a long way.

When & How to Harvest Strawberries

Now for the part you've been waiting for! With berries hanging outside the tower, you can watch them ripen without hunting underneath a tangle of plants.

Wait until they develop their mature color before picking. Strawberries don't continue ripening the way some other fruits do after harvest, so a little patience helps protect that flavor.

Pinch or snip the stem just above the ripe berry rather than tugging hard. You want to pick your strawberry, not bring half the plant along with it!

Check productive plants regularly. Once berries start ripening, you may find more ready to pick every few days. Whether they make it all the way to the kitchen is another question. 🍓

Are Strawberries a Good Crop for a Tower Garden?

Absolutely—especially if you're happy to give them a little more attention than your leafy greens.

They stay relatively compact, don't need trellising, and keep their fruit hanging outside the tower where you can see it. You can even grow them indoors with sufficient light and a little help with pollination.

Just remember that strawberries are a fruiting crop. Growing leaves is the easier part. Turning flowers into tasty berries takes the right combination of variety, light, temperature, nutrition and pollination.

Get those pieces working together, and there's something pretty satisfying about walking up to your Tower Garden and picking a strawberry straight from the plant. That's a snack worth growing!
