#563 Why Aren’t My Tomatoes Ripening? (Frustration and Desperation)

The Veg Grower Podcast

In the latest episode of the Veg Grower Podcast, host Richard delves into the intricacies of tomatoes ripening, shares an innovative upcycling project, and discusses the benefits of a new compost tumbler on his allotment. Additionally, Scott brings a delightful culinary twist with a recipe for lemon and elderflower posset with red gooseberry compote. Understanding and Solving Tomato Ripening Issues The Science Behind Tomato Ripening Richard begins by addressing a common issue many gardeners face: tomatoes not ripening as expected. He explains that the ripening process is influenced by the plant hormone ethylene, which is crucial for the development of the fruit's colour and flavour. Environmental factors such as temperature and sunlight play a significant role in ethylene production. Factors Affecting Ripening Temperature:** Tomatoes require a consistent temperature range of 21-24°C for optimal ripening. Temperatures above 85°F (29°C) or below 50°F (10°C) can hinder the process.Sunlight:** Adequate sunlight is essential for photosynthesis, which in turn supports the ripening process. Ensure your tomato plants receive at least 6-8 hours of direct sunlight daily. Practical Solutions Richard offers several practical solutions to encourage tomato ripening: Remove Lower Leaves:** By removing the lower leaves of the tomato plant, you can improve air circulation and reduce the risk of disease, which can indirectly support ripening.Use Ethylene-Emitting Fruits:** Placing bananas near your tomato plants can help. Bananas emit ethylene gas, which can accelerate the ripening process.Prune and Pinch:** Regularly prune and pinch off suckers (the small shoots that grow between the stem and branches) to direct the plant's energy towards fruit development. Upcycling Project: Turning Tomato Sauce Tins into Plant Pots The Benefits of Upcycling Richard introduces an upcycling project where he repurposes large tins of tomato sauce as plant pots. Upcycling not only reduces waste but also provides a cost-effective solution for gardening. Step-by-Step Guide Prepare the Tins: Clean the tins thoroughly and remove any labels.Drill Drainage Holes: Use a drill to create several drainage holes at the bottom of each tin to prevent waterlogging.Add Perlite and Compost: Fill the tins with a mixture of perlite and compost to ensure good drainage and nutrient availability.Planting: Richard chose to plant ginger in his upcycled pots, but you can experiment with various plants based on your preference. Encouraging Creativity Richard emphasizes the importance of creativity in gardening. Upcycling projects like this not only benefit the environment but also add a unique touch to your garden. Consider using other discarded items such as old buckets, tires, or even broken furniture to create functional and aesthetically pleasing garden features. Efficient Composting with a New Tumbler Advantages of a Compost Tumbler Richard shares his excitement about a new compost tumbler he received for his allotment. Compost tumblers offer several advantages over traditional compost bins: Faster Composting:** The tumbling action aerates the compost, speeding up the decomposition process.Ease of Use:** Tumblers are easier to turn and manage, making them ideal for gardeners with limited physical strength.Pest Control:** Enclosed tumblers reduce the risk of pests such as rodents and insects. Tips for Effective Composting Balance Green and Brown Materials:** Ensure a good mix of green (nitrogen-rich) and brown (carbon-rich) materials. Green materials include kitchen scraps and grass clippings, while brown materials include leaves and cardboard.Maintain Moisture Levels:** The compost should be as moist as a wrung-out sponge. Add water if it’s too dry or dry materials if it’s too wet.Regular Turning:** Turn the compost regularly to aerate it and speed up the decomposition process.
