Add Items to Basket
Quick Overview
800 gram box of Chempak High Potash Feed (Number 4). Useful for flowering bonsai trees to increase the number and size of flowers.

Product Description


The soluble plant food for better blooms and bigger crops.

All Chempak Soluble Plant Foods contain seven essential trace elements, far more than ordinary soluble fertiliser. These trace elements are absolutely necessary to plant growth and serious disorders can occur if any are absent. They are fully soluble which means they start to work instantly.


Chempak Formula 4 is a balanced plant food with a high potash content, perfect for boosting flowering and fruit producing bonsai trees.

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


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.


Should only be used for flowering trees during the summer. Switch to Chempak Formula 8 or Formula 3 at other times.

Free Measuring Spoon & Feeding Guide included with every pack.
