In our latest episode of “Grow it, Sow it, Cook it,” we explored the topic of pinching and topping plants, particularly focusing on tomatoes, peppers, and potatoes. Here’s a comprehensive look at the discussion, shedding light on the benefits and techniques of these gardening practices.

Podcast Episode 17: To Pinching or Not?

Pinching Explained

Pinching involves removing the flowers or growth tips of plants. The idea is to redirect the plant’s energy from producing flowers to strengthening its roots, stems, and leaves. This practice can lead to a more robust plant that will eventually yield more fruit. Here are the key points discussed:

  1. Tomatoes:
  • Pinching off the flowers of young tomato plants (especially if they are under 12 inches tall) helps the plant focus on growing stronger before it starts bearing fruit. This can result in a larger harvest later in the season.
  • Yes, it will put off your initial fruit by a few weeks, so if you have a short growing season, you probably don’t want to pinch and stall your fruiting.
  • For indeterminate tomato varieties, pinching can be beneficial as these plants continue to grow and produce fruit throughout the season.

2. Potatoes:

    • Removing the flowers from potato plants helps the plant divert energy towards tuber production rather than flowering. This can lead to bigger and more numerous potatoes.

    3. Peppers:

    • Just like tomatoes, some gardeners like to pinch off the first blossoms of pepper plants so the energy goes into developing strong stems. It is really up to the gardener.

    Topping Explained

    Topping refers to cutting off the top part of the plant. This technique is used to control the height of the plant and to focus the plant’s energy on maturing its existing fruits rather than producing new ones.

    1. Topping Tomatoes:
    • Topping is usually done towards the end of the growing season when you want the plant to stop growing taller and focus on ripening the fruit it has already set.
    • This practice can prevent the plant from becoming too unwieldy and ensures that the energy is used efficiently to ripen the fruit.

    2. Topping Peppers:

    Topping peppers is a common technique among gardeners to promote bushier plants and potentially increase yield. The concept is straightforward: by cutting off the top of the plant, you encourage it to grow more lateral branches, which can lead to more flowers and fruits.

    Peppers, especially when they’re still young and under 12 inches tall, can benefit greatly from topping. By removing the top growth, the plant diverts its energy from growing tall to developing a sturdier structure with more branches. This can result in a healthier plant that can support a greater number of fruits.

    You can top pepper seedlings or wait until you have planted them out in the garden. If you top them as seedings, whether you have hardened them off or not, give them a little time to recuperate before the next step, either hardening them off or planting them in the garden. The idea is to give them only one stressor at a time with a week or two to recover.

    Our Experiment with Topping

    Karen shared her method:

    “I pinch the flowers off of my pepper plants that were under 12 inches. The bigger ones, I let them grow. We’ll see how it turns out.”

    She highlighted that sometimes early blossoming in small plants can be a sign of stress, possibly from cool nights. When a pepper plant feels stressed, it might rush to flower and produce seeds as a survival mechanism. By topping these stressed plants, you can alleviate the stress and allow the plant to focus on growing stronger.

    Tips for Topping Peppers

    • Timing: Top your pepper plants when they are about 6-12 inches tall.
    • Technique: Use clean, sharp scissors or pruning shears to cut just above a set of leaves.
    • Aftercare: Monitor the plant for a few days to ensure it’s recovering well. You might notice new growth emerging from the nodes below the cut.

    Topping is an easy and effective way to manage your pepper plants, especially if you aim for a bountiful harvest. Remember to experiment and observe how your specific varieties respond, as results can vary.

    Topping Flowers: Encouraging Stronger Growth

    Topping flowers is useful for encouraging bushier plants and more vibrant blooms. By removing the top growth of a flower plant, gardeners can stimulate the plant to produce more lateral branches, leading to a fuller and more attractive appearance. This method is especially beneficial for flowering plants that tend to grow tall and leggy. (zinnias!) As discussed in our podcast, topping can help manage plant height and create a more aesthetically pleasing garden.

    Karen shared her insights on topping flowers, emphasizing the importance of timing. She mentioned that it’s crucial to pinch off flowers when the plants are still small, typically under 12 inches tall. This helps redirect the plant’s energy from vertical growth to producing more branches and flowers. Topping can relieve plants that are showing signs of stress, such as early flowering. By removing these early blooms, the plant can focus on developing a stronger structure and eventually produce more flowers.

    Whether you are growing flowers mainly for their pollinating benefits, for their beauty, for cut flowers, or all of the above, topping them will increase your yield and give you more flowers for the pollinators and for your flower arrangements. You cannot have too many flowers!

    Practical Insights from Our Podcast

    During the podcast, Sherva shared a personal anecdote about accidentally snapping off a large section of her tomato plant. Despite the initial setback, she stuck the broken piece into the soil, and it rooted successfully. This incident illustrates the resilience of tomato plants and the practical application of pinching and topping techniques.

    We also discussed experiments with pinching flowers on tomato plants. Karen decided to pinch the flowers off half of her tomato plants to compare the outcomes with the other half. This kind of experimentation helps gardeners understand what works best for their specific conditions and plant varieties.

    Conclusion: Pinching and Topping

    Pinching and topping are valuable gardening techniques leading to healthier plants and better yields. While removing flowers or cutting off parts of your plants might feel counterintuitive, these practices can ultimately result in a more productive garden. If you’re trying these methods for the first time, consider experimenting with a few plants and comparing the results. Happy gardening!
