Ever bite into a sun-warmed cherry tomato, so bursting with sweetness and flavor that you think, "I wish I could have a whole garden of these!"? Well, guess what? You absolutely can! It's easier than you might think to grow tomatoes from cherry tomatoes themselves. This guide will walk you through the process, from seed selection to delicious harvest, so you can enjoy a bountiful supply of these little red jewels.
Can You Really Grow Tomatoes From Cherry Tomatoes?
The short answer is: yes, you absolutely can! Growing tomatoes from cherry tomatoes is a fun and rewarding way to propagate new plants. The process involves saving the seeds from a ripe cherry tomato and germinating them to produce seedlings. However, there are a few important things to keep in mind to ensure success. It’s not quite as simple as just burying a tomato in the ground, but with a little know-how, you'll be well on your way to enjoying a homegrown cherry tomato harvest.
A key factor in successful seed saving is understanding the concept ofhybrid vs. heirloom tomatoes. Hybrid tomatoes are created by cross-pollinating two different tomato varieties. While they often offer desirable traits like disease resistance or higher yields, their seeds won't "breed true." This means that the plants grown from hybrid tomato seeds might not produce tomatoes that are exactly like the parent tomato. Heirloom tomatoes, on the other hand, are open-pollinated varieties that have been passed down for generations. Their seeds will produce plants that are true to type, meaning you'll get the same delicious cherry tomatoes you expect.
Choosing the Right Cherry Tomato Variety for Seed Saving
Selecting the right cherry tomato variety is the first crucial step. As mentioned, for the best results, opt forheirloom varieties. Look for labels at your local farmer's market or garden center that specify "heirloom" or "open-pollinated." Popular heirloom cherry tomato varieties include:
- Black Cherry: Known for its dark, almost smoky flavor.
- Sungold: Incredibly sweet and vibrant orange.
- Dr. Carolyn: A creamy white cherry tomato with a mild flavor.
- Yellow Pear: Distinctive pear shape and a mild, slightly tangy taste.
Avoid saving seeds from cherry tomatoes you purchased at the grocery store unless you are absolutely certain they are heirloom. Most commercially available cherry tomatoes are hybrids. If you choose to experiment with hybrid seeds, be prepared for potentially unpredictable results in terms of fruit shape, size, color, and flavor.
Saving Cherry Tomato Seeds: A Step-by-Step Guide
Saving cherry tomato seeds requires a simple fermentation process that removes the pulp surrounding the seeds and prevents them from germinating prematurely.
Step 1: Selecting Ripe Tomatoes
Choose the ripest, healthiest-looking cherry tomatoes from your plant. These tomatoes should be fully colored, slightly soft to the touch, and free from any blemishes or signs of disease.
Step 2: Extracting the Seeds
Cut the tomatoes in half and scoop out the seeds and surrounding pulp into a small jar or container. Add a small amount of water to the jar – just enough to cover the pulp. This fermentation process is crucial to remove germination inhibitors.
Step 3: Fermentation
Leave the jar at room temperature for 3-4 days, stirring daily. You'll notice a layer of mold forming on the surface – this is normal and a sign that the fermentation process is working. The healthy seeds will sink to the bottom of the jar, while the non-viable seeds and pulp will float.
Step 4: Cleaning the Seeds
After fermentation, carefully pour off the moldy liquid and floating pulp. Add fresh water to the jar and swirl the seeds around. Allow the seeds to settle to the bottom and pour off the water again. Repeat this process several times until the water is clear. This ensures you're only left with the viable seeds.
Step 5: Drying the Seeds
Spread the clean seeds in a single layer on a paper towel or coffee filter. Label the paper towel with the tomato variety and the date. Allow the seeds to dry completely in a cool, dry place for about 1-2 weeks. Make sure the seeds are completely dry before storing them; otherwise, they may mold.
Step 6: Storing the Seeds
Once the seeds are completely dry, store them in an airtight container, such as a glass jar or envelope. Store the container in a cool, dark, and dry place. Properly stored tomato seeds can remain viable for several years.
Germinating Your Cherry Tomato Seeds
Now that you have your saved cherry tomato seeds, it's time to germinate them and grow some new plants!
Starting Seeds Indoors
Starting seeds indoors gives your tomato plants a head start, especially if you live in a region with a short growing season. Here's how to do it:
- Timing: Start your seeds indoors 6-8 weeks before the last expected frost.
- Seed Starting Mix: Use a sterile seed starting mix to prevent diseases.
- Containers: Use seed starting trays, small pots, or even recycled containers with drainage holes.
- Sowing: Sow the seeds about ¼ inch deep in the soil.
- Watering: Keep the soil consistently moist but not waterlogged.
- Warmth: Provide warmth by placing the seed trays on a heat mat or in a warm location. The ideal germination temperature for tomato seeds is between 70-80°F (21-27°C).
- Light: Once the seedlings emerge, provide them with plenty of light. Use grow lights or place them in a sunny window.
Consider using an indoor growing system to help with germination! For example, the Ahopegarden Indoor Garden Hydroponics Growing System, also known as a 10 Pods Plant Germination Kit, uses Aeroponic technology and includes a countertop LED grow light to help your herbs and vegetables thrive, even during winter. You can find this hydroponic planter on Amazon: https://amzn.to/3RPpa Sk. With this vegetable growth lamp, starting your seeds indoors is now an easier task.
Direct Sowing Outdoors
In warmer climates with a long growing season, you can direct sow cherry tomato seeds outdoors. However, this method is generally less reliable than starting seeds indoors.
- Timing: Sow the seeds after the last expected frost when the soil has warmed up to at least 60°F (15°C).
- Soil Preparation: Choose a sunny location with well-drained soil. Amend the soil with compost or other organic matter.
- Sowing: Sow the seeds about ¼ inch deep in the soil.
- Watering: Keep the soil consistently moist until the seedlings emerge.
- Thinning: Once the seedlings have a few true leaves, thin them to the strongest plants, spacing them about 18-24 inches apart.
Transplanting Your Cherry Tomato Seedlings
Whether you started your seeds indoors or purchased seedlings from a nursery, it's important to transplant them properly to ensure their success.
Hardening Off Seedlings
Before transplanting seedlings that were started indoors, you need to "harden them off." This process gradually acclimates the seedlings to outdoor conditions, preventing transplant shock. Expose the seedlings to increasing amounts of sunlight and outdoor temperatures over a period of 7-10 days. Start with just an hour or two of exposure and gradually increase the time each day.
Transplanting
Choose a sunny location with well-drained soil. Dig a hole that is slightly larger than the root ball of the seedling. Gently remove the seedling from its container and loosen the roots. Plant the seedling deep, burying the stem up to the first set of leaves. This will encourage the plant to develop a stronger root system. Water the seedling thoroughly after planting. Add a layer of mulch around the base of the plant to help retain moisture and suppress weeds. If there's danger of frost, ensure you cover the plants.
Caring for Your Cherry Tomato Plants
Once your cherry tomato plants are in the ground, proper care is essential for a bountiful harvest.
Watering
Water your tomato plants deeply and regularly, especially during hot, dry weather. Aim to water at the base of the plant to avoid wetting the foliage, which can lead to diseases. A good rule of thumb is to water when the top inch of soil feels dry.
Fertilizing
Fertilize your tomato plants regularly with a balanced fertilizer. Follow the instructions on the fertilizer label. You can also amend the soil with compost or other organic matter to provide nutrients.
Pruning
Pruning tomato plants can improve air circulation, promote fruit production, and prevent diseases. Remove suckers (the small shoots that grow between the main stem and the branches) to encourage the plant to focus its energy on fruit production. However, some gardeners prefer to leave some suckers to allow for more fruit production.
Support
Cherry tomato plants can get quite tall and heavy, so they need support to prevent them from collapsing. Use stakes, cages, or trellises to support your plants. Tie the plants to the support structure as they grow.
Pest and Disease Control
Keep an eye out for common tomato pests and diseases, such as aphids, tomato hornworms, and early blight. Take steps to control pests and diseases early on to prevent them from spreading. Consider using organic pest control methods, such as insecticidal soap or neem oil.
Harvesting Your Cherry Tomatoes
Harvesting is the most rewarding part of growing cherry tomatoes! Cherry tomatoes are typically ready to harvest 60-80 days after transplanting. Pick the tomatoes when they are fully colored, slightly soft to the touch, and easily detach from the vine. Harvest regularly to encourage the plant to continue producing fruit.
Enjoying Your Homegrown Cherry Tomatoes
Congratulations! You've successfully grown tomatoes from cherry tomatoes! Now it's time to enjoy the fruits of your labor. Cherry tomatoes are delicious eaten fresh, added to salads, roasted, or used in sauces. They are an incredibly versatile ingredient and can be used in a wide variety of dishes. Enjoy!
