How To Harvest Stevia So it Keeps Growing?

by | Aug 8, 2024 | How To

Growing and harvesting stevia is a rewarding hobby for home gardeners. This bushy, perennial herb has leaves that are sweeter than sugar. To keep my stevia plants healthy and full of leaves, I follow some important care tips.

I start stevia plants from seed indoors, 10 weeks before the last frost. This gives them a strong start before they go outside. Stevia likes rich, well-draining soil and full sun.

Keeping stevia plants moist is key, but I don’t overwater them. Trimming and pruning help them grow bushy and produce more leaves. I only cut off one-third of the plant at a time to help it recover.

By harvesting and caring for my stevia plants correctly, I get a steady supply of this sweetener. With a little effort, stevia becomes a valuable part of any garden.

Understanding Stevia: A Sweet Perennial Herb

Stevia is a special herb that has been around for centuries in South America. It’s a natural sweetener that’s up to 15 times sweeter than sugar but has no calories or health risks. Growing your own stevia lets you enjoy its many benefits.

What is Stevia?

Stevia is a tender perennial plant that does well in warm places. It can survive winters in zones 9 and above. Gardeners in zone 8 can keep stevia alive through winter with the right care.

The sweetness of stevia comes from compounds in its leaves. These plants can grow up to 2.5 feet tall and produce small white flowers in the fall. But the leaves are tastiest and sweetest before they bloom, so harvest them in autumn.

Benefits of Growing Your Own Stevia

Homegrown stevia is full of antioxidants and doesn’t affect blood pressure or insulin levels like sugar does. Studies show it can help prevent tooth decay, gum disease, and colds and flu.

It’s easy to grow your own stevia at home. It likes well-drained soil with a pH between 6.7 and 7.2. With about 18 inches of space between plants, a 12-inch pot with full sun can give you a big harvest.

Dried stevia leaves are very potent – just 1/8 teaspoon is as sweet as 1 teaspoon of sugar. This makes homegrown stevia a great, healthier choice instead of processed sugar substitutes.

Planting and Growing Stevia

Stevia is a great herb to grow at home. You can start it from seeds or move seedlings. With the right care, you’ll get a lot of this sweet herb.

Starting Stevia from Seeds

Start stevia seeds indoors 8-10 weeks before the last frost. They germinate in 21 days if kept moist and warm. Once they’re big enough, move them to pots and keep them indoors until it gets warm at night.

Ideal Growing Conditions for Stevia

Stevia likes rich, well-drained soil with a pH of 6.5-7.5. It needs full sun but can handle some afternoon shade. Plant them 18 inches apart in rows 24 inches apart for best growth. It also does well in containers, perfect for indoor growing all year.

Keep the soil moist but not too wet. Feed them with a balanced, organic fertilizer every few weeks in the growing season. With the right care, you’ll have plenty of stevia soon.

Pruning and Trimming Stevia Plants

Maintaining a thriving stevia plant needs a bit of care, especially with pruning and trimming. To encourage bushy growth and a steady harvest, prune your plants often. Let’s explore how to trim stevia plants right.

When your stevia plants hit about 8 inches tall, it’s time to prune. Cutting them back makes them spread out more, leading to a fuller plant. This means more leaves for you. Also, take out any flower buds as they show up to keep the plant focused on making leaves.

Prune your stevia every 4-6 weeks when it’s warm. This keeps your plants full of tasty leaves all season. Always use sharp, clean tools for cutting to avoid diseases.

Pruning also boosts air flow around the leaves and stems. This lowers the chance of rot and pests, keeping your plants healthy. With regular care, you’ll get a lot of sweet stevia leaves all season.

Proper Harvesting Techniques

Harvesting your stevia correctly is key to keeping it healthy and productive. You can take leaves one by one or cut whole stems. But, never take more than one-third of the plant at once. This keeps the plant strong and helps it keep growing.

For the sweetest leaves, harvest before the plant flowers. Flowering makes the leaves taste bitter. Harvesting in autumn, when it’s cooler, gives you the best flavor.

Timing Your Stevia Harvest

Stevia is a tough perennial herb, but harvesting right keeps it thriving. Harvest in the morning for the sweetest leaves. Don’t harvest in the heat of the day to avoid stressing the plant.

For ongoing harvests, cut your stevia at different times during the season. This lets the plant recover and grow new, tasty leaves. Always leave at least 4 inches of stem at the base to help the plant come back strong next season.

Preserving and Using Harvested Stevia

After harvesting your stevia, it’s important to preserve it for later use. There are several ways to do this, each with its own benefits.

Drying and Powdering Stevia Leaves

Drying stevia leaves is a simple way to keep them. You can hang the stems upside down in a dry area or spread the leaves on a screen outside. Once dry, crush the leaves or grind them into powder with a mortar and pestle or a spice grinder.

This powder can sweeten your drinks, foods, and baked goods. Use about 1/8 teaspoon to replace 1 teaspoon of sugar.

Making Stevia Extract and Tincture

Creating a stevia extract or tincture is another way to preserve it. To make extract, steep crushed stevia leaves in hot water for 40 minutes. Then, strain the mixture and keep the liquid in a dark jar in the fridge.

This extract can sweeten drinks like tea or smoothies. It’s as sweet as 3 cups of sugar with just 3/4 cup of extract.

For a tincture, use fresh stevia leaves and soak them in rum or vodka. Heat it until it becomes syrupy. Store this tincture in a dark bottle for up to 3 months.

Preserving Stevia Leaves

“Stevia plants contain steviol glycerides, which are 300 times sweeter than sucrose, providing sweetness without any calories.”

Whether you dry, powder, extract, or tincture your stevia, keep it fresh and flavorful. With a bit of care and creativity, you can enjoy your homegrown stevia for months.

Overwintering and Regrowing Stevia

As winter comes, it’s key to take good care of your stevia plants. They will die back in the cold but their roots can survive. This means you can regrow them in the spring.

Here’s how to help your stevia plants survive the winter:

  1. Bring container-grown stevia indoors. Before the first frost, move your potted stevia plants to bigger containers with fresh soil. Put them in a sunny spot indoors, like a window or under grow lights.
  2. Mulch in-ground stevia plants. For stevia in your garden, cover the base with organic mulch. This keeps the roots warm and safe from the cold.

With the right overwintering care, your stevia plants will regrow in the spring. As it gets warmer, new leaves will grow from the roots. Then, you can take care of them like before. Soon, you’ll have plenty of fresh, sweet stevia leaves to enjoy.
