Water Issues

The plant(s) looks fairly healthy, and since there are flowers, you should expect to see tomato fruits beginning to develop soon. We do have some recommendations: You may be watering too often, which can increase vegetative growth (especially in combination with increased fertilizers, particularly those high in Nitrogen), and reduce or delay flowering and fruit set. Conversely, tomatoes do need more nutrition during certain stages of growth, like at flower & fruit-set. So if you haven’t fertilized, you should consider doing that. Your local garden center will have the appropriate fertilizers. We’ve included a link about growing Tomatoes with info about their common issues/challenges, but we can recommend watering more deeply less often, rather than applying smaller amounts every day. Tomatoes are deep rooted plants, and if water is available will be healthier. Do not allow extreme fluctuations in soil moisture, but try to water according to the plants needs (temp and humidity affect those needs). You can water when the upper 2inches of soil is dry and apply an adequate amount. Use “water cycling” if water does not enter the soil quickly.
