Doff Power Up Ultimate Tomato Feed Liquid Concentrate 1 Litre

Doff Power Up Ultimate Tomato Feed is a high potash concentrated liquid feed, enriched with seaweed extract for added plant benefits. Part of Doff's premium Power Up range, it delivers exactly the nutrients fruiting plants need — promoting better fruit development, improved flavour, and richer colour throughout the growing season.

Ideal for use on tomatoes grown in the greenhouse or outdoors, and equally effective on peppers, aubergines, cucumbers, and other fruiting crops. Simply dilute in water and apply directly to the roots — no specialist equipment needed. Suitable for use with a standard watering can or irrigation system.

The fast-acting concentrated formula means a single 1 litre bottle goes a long way, giving you a full season's worth of feeding from just one purchase. The high potash (K₂O 8.0%) content is specially formulated to deliver the nutrients that drive fruit set and development, whilst the seaweed extract provides additional natural plant benefits.

Frequently Asked Questions

What makes this different from a standard tomato feed?
Doff Power Up Ultimate Tomato Feed is enriched with seaweed extract, which provides additional natural plant benefits on top of the NPK nutrients. The high potash formula (K₂O 8.0%) is specifically targeted at fruiting crops to improve fruit set, flavour, and colour — rather than promoting leafy growth.

Can I use this on plants other than tomatoes?
Yes. It is suitable for all fruiting crops including peppers, aubergines, cucumbers, and other fruiting vegetables. The high potash formula benefits any plant where fruit or flower development is the goal.

How much does 1 litre make up?
At the recommended dilution of 10ml per 4.5 litres of water, one 1 litre bottle makes approximately 450 litres of ready-to-use feed — enough for a full growing season for a typical home greenhouse or garden plot.

When should I start feeding?
Begin feeding from the first flower and continue every 7–14 days through to the end of the season. Do not apply before flowering — leafy growth does not benefit from this high potash formula.

Is it safe to use near a pond or water feature?
No. This product is not safe for use near water. Keep it away from ponds, streams, ditches, and water features when applying.
