Helping Your Tomato Plants with Soil-Borne Diseases and Nutrient Deficiencies | Take Steps to Improve their Health!
It looks like your tomatoes may be suffering from a soil-borne disease. The most likely culprit is Septoria, which is characterized by brown spots on the leaves and can cause stunted growth and leaf loss. Fusarium wilt is another possibility, although it usually causes wilting of the entire plant rather than just yellowing or brown spotting of the leaves.
The soil analysis you had done before planting showed that your soil was low in nitrogen but otherwise had sufficient nutrients. You added a combination of compost, feather meal, and blood meal to improve the nutrient content of the soil. However, too much feather meal can cause excess nitrogen levels, leading to symptoms such as curled leaves and blossom drop. It's possible that this could have contributed to the current problems with your plants.
To try to address the issue, you've applied liquid fertilizer higher in phosphorus and potassium twice over two weeks. Unfortunately, this doesn't appear to have made any visible improvement yet. If you suspect Septoria, there are several fungicides available that can help control it. Additionally, if you haven't already done so, adding some organic matter to your soil can help improve its structure and nutrient content. This will give your plants better access to the nutrients they need for healthy growth.It's also possible that the problem isn't a soil-borne disease at all. If you've been using overhead irrigation, this can cause fungal diseases such as powdery mildew and downy mildew to develop on your plants. These are both characterized by white or gray patches on the leaves and stems of affected plants. To prevent these from occurring, it's important to water only at ground level rather than from above.
Finally, if none of these solutions seem to be helping your tomatoes recover, it may be time for a more drastic measure: replanting in new soil with fresh compost added in order to give them an extra boost of nutrients they need for healthy growth. This is especially true if you suspect Septoria or Fusarium wilt; since these diseases can remain in the soil even after treatment with fungicides, starting over with clean soil is often necessary for successful control measures.
No matter what issue your tomato plants are facing – whether it’s a nutrient deficiency due to poor quality soil or an infection caused by fungi – there are steps you can take towards improving their health and ensuring they produce delicious fruits throughout the season! With careful monitoring and timely interventions when needed, you should have no trouble keeping your tomatoes happy and productive all summer long!
What is the issue with my tomatoes?
It looks like you may be dealing with a combination of fusarium wilt and early blight. Fusarium wilt can be identified by slight browning or dark yellowing in the vascular tissue just under the skin when cutting off one of the more affected stems. Early blight can be seen as typical brown spots on the leaves.
What soil analysis was done before planting?
The soil analysis showed that the clay dirt was very low on nitrogen and iron, and suggested mixing in a combination of compost, feather and blood meals.
Are all of my tomato plants affected?
It appears that most of your tomato plants are exhibiting stunted growth and signs of disease in the lower leaves. Even the few hybrids purchased from nursery are exhibiting similar characteristics.
Could this be fertilizer burn?
It is possible that this could be fertilizer burn, however it is more likely to be fusarium wilt or early blight.
How can I treat this issue?
You can try applying liquid fertilizer higher in phosphorus and potassium a couple times, spaced out 2 weeks apart. Additionally, you may want to give your plants some phosphorus-rich fertilization. You can also try using a fungicide to treat the affected areas.
