Where to use:
Chempak Formula 4 is a balanced plant food with a high potash content, perfect for boosting fruit and flowers, giving it an all round summer use on borders and vegetable plots.

Use on: bedding plants, peppers, soft fruit, perennials, potatoes, tomatoes, houseplants, fuchsias, ornamental trees, root vegetables, flowers and hanging baskets.

How & when to use:

Normal Strength Use: Dissolve 2 level measures of crystals in 5 litres (approx.1 gallon) of water and apply to your plants every 7 to 10 days. Ensure the soil or compost is well moistened.

For more frequent use: Some gardeners prefer to use dilute feed more often. Dissolve 1 level measure in 10 litres of water and apply at every watering. At this strength this pack will make over 2,000 litres of plant food.

Professional tips:

Tomatoes: Feed weekly from early stages. Increase frequency to twice a week when fruiting to improve quality and yield.

Hanging Basket & Container Plants: The perfect summer feed for begonias, fuchsias, geraniums, and pelargoniums, etc. Use at bud stage and continue through the flowering period to ensure a succession of blooms.


Free Measuring Spoon & Feeding Guide included with every pack.
