Tomatoes need consistent water, appropriate fertility, sunlight and disease management. A plant tonic is only one part of that system.
Use the current label
Shake well, measure carefully and use the dilution method printed on the bottle. Do not increase concentration to try to force faster growth.
Choose a sensible application time
In hot Florida conditions, gardeners often find it easier to apply soil drenches during cooler morning or evening periods. Avoid applying before a heavy rain that could wash the product away.
Watch the whole plant
Yellowing, blossom-end rot, leaf spots or stalled growth can have different causes. Check watering, soil moisture, fertility, pests and disease rather than assuming every symptom needs more product.
