I am growing tomatoes called Moneymakers which aren’t ripening up well. Could it be that there is too much fruit on the vine? My Cherry tomatoes haven’t had any problems.
Cherry tomatoes are one of the easiest tomato varieties to grow, however other tomato varieties - particularly the larger fruiting ones, do require a bit more care and attention. It is possible your Moneymaker tomato vines have too much fruit on them. This could have occurred because the plants were not de-lateraled frequently enough throughout their growth, which has lead to over cropping. De-lateraling is the removal of laterals which are shoots that appear between the junction of a leaf branch and the stem.
In terms of ripening, there may also be a problem with light access to the young tomatoes. To overcome this; remove some leaves and/or laterals to allow enough sun through. Tomatoes do require a lot of water, especially around fruiting time and during the hotter months. For healthy fruit it is critical you water plants deeply two to three times a week, regardless of rainfall.
Feed your tomato plants with a tomato fertiliser every 3-4 weeks right throughout the growing period. Add a good layer of mulch on top to help conserve water and keep moisture in the soil.
Top tip: When pruning your tomato plant use sharp secateurs and ensure they are clean before you start to avoid spreading diseases.
