Vitax Hydrangea Liquid Feed 1L Concentrated Fertiliser For Vibrant Blooms

You should start using the feed weekly from March, continuing through to August for the main growing and flowering season.

This feed is specifically formulated for hydrangeas. While some nutrients might be beneficial to other plants, it is best used as directed for optimal hydrangea health and flowering.

Always refer to the specific dilution instructions on the product packaging, as this can vary. A common recommendation is one capful per gallon (4.5 litres) of water.

The feed is suitable for all soil types. However, improving drainage in heavy clay soil by adding organic matter can help ensure nutrients are readily available to the plant's roots.

This product is a synthetic fertiliser and may not be suitable for strict organic gardening practices. Please check the product label for specific certifications.

For hydrangeas in pots, weekly application from March to August is recommended to replenish nutrients that can be quickly leached from containers.

While sunlight is crucial for flowering, the feed provides the necessary nutrients to support bloom development. Ensuring the plant is otherwise healthy and receives adequate water will maximise its flowering potential, even in shade.

This can be a sign of nutrient deficiency, particularly iron. Ensure you are using the feed regularly as directed and that the soil is not waterlogged, as this can inhibit nutrient uptake. If using peat-free compost, ensure it has adequate wetting agents.

Ensure the plant is receiving adequate sunlight and water. Check that you have been applying the Vitax Hydrangea Liquid Feed consistently throughout the growing season, as this directly promotes flowering.

Shake the bottle vigorously before diluting. If the product is significantly separated or has an unusual odour, it may have degraded and should be replaced.

This usually indicates over-fertilisation. Ensure you are diluting the concentrate correctly according to the product instructions. If you have accidentally applied a stronger solution, water the plant thoroughly with plain water to flush the soil.
