Expert in gardening discusses causes of tomato splitting and provides solutions to stop the issue

In the world of gardening, tomato splitting can be a frustrating issue for both beginners and seasoned gardeners alike. This common problem often occurs in greenhouses or polytunnels when temperatures soar, reaching up to 40-50 degrees.

According to Ish, a renowned gardening expert who can be found on Instagram at @Gardening.with.ish, regular watering is key to preventing tomato splitting. Proper watering not only helps prevent splitting but also promotes healthy growth and ripening of the fruit.

Ish also recommends feeding tomato plants weekly. A specific tomato feed enriched with seaweed extract can be used to nourish and fertilize these high-yielding plants. This practice not only benefits tomatoes but also high-yielding flowers such as petunias and other trailing plants.

When it comes to tools, the Gold Leaf RHS collections Chelsea Ladies Comfortable Leather Gardening Gloves are suitable for tending to tomato plants, while popular secateurs with carbon steel blades and lightweight, non-slip handles are ideal for harvesting ripe tomatoes.

However, if your tomatoes have already started splitting, Ish explains that the cause is often too high temperatures in a greenhouse, leading to rapid water uptake and uneven fruit growth. Underwatering or irregular watering can exacerbate the problem, leading to leaf curling and stress.

In such cases, continuing to water a stressed tomato plant can help it recover and produce more flowers and fruit. It's important to remember to open vents in greenhouses or polytunnels to allow fresh air and lower the temperature, which can help prevent further splitting.

While the article does not provide information on how to reverse the splitting of tomatoes before it goes too far, Ish has shared his expertise on the topic of splitting and how to address it. By following these tips, you can help ensure a bountiful tomato harvest in your garden.
