Should potted tomato plants be pruned?
Pruning tomato plants is optional, and you should only prune indeterminate varieties. Do you like to train your plants and check up on them almost every day? If so, then you may be a natural tomato pruner. Topping forces the energy from the plant into the remaining fruit and can hasten ripening. Removing the growing tip by topping also limits the plant’s final size, which can be important for larger varieties. Greenhouse tomato growers will top plants when they reach the top of the trellis.The same approach applies for pruning tomato plants in pots or growing in the ground. Later in the season, as your tomato plant matures, cut off any yellowing or dead leaves where they join the main stem – the leaves close to the ground tend to yellow first.Remove leaves Removing some of the leaves will help the sun reach the tomatoes, and they will ripen faster. The plant will focus more energy on growing the tomatoes if you remove some of the leaves too. I remove all of the leaves up to the first tomato bunch on the main stem.
What happens if you don’t prune tomatoes?
If you don’t prune your indeterminate tomatoes, they can get out of control. This can lead to difficulty in caring for the tomatoes and harvesting them. In some cases, tomatoes left on their own show signs of less overall plant health. There are 2 basic types of tomatoes. Determinate grows to a certain pre-determined height; indeterminate just keeps on growing the whole season. You should not top or otherwise prune determinates. Tomato plants can be cleaned and trimmed like any other plant.
What to do with tomatoes in October?
The simplest is to bring them into a warm room and place them in a paper bag with a ripe banana or apple. Both release ethylene gas, which encourages ripening. Keep the bag loosely closed, check daily, and you’ll often find the tomatoes take on full colour within a week. Until the plants begin flowering, you can use a balanced fertilizer with a 1-1-1 ratio such as 20-20-20. Once flowering, change over to a high potassium fertilizer. Most fertilizers blended for tomatoes fit this description. In our program, we’ve been using a fertilizer with a 9-15-30 plus micro-nutrients analysis.Tomatoes are moderate feeders and too much fertilizer will promote lush growth at the expense of fruit. Feed tomatoes when the fruit is about 1 inch (2. Use a product relatively low in nitrogen (the first number of the NPK ratio on the front of the package).Tomatoes planted in August or early September will grow quickly in the warm soil, warm nights and long days. They will begin setting fruit quickly. As we move into the cooler nights and shorter days of October and November the fruit will already have been set.
