Cheapest to buy

Houseplant Feed Concentrate, 200ml

A low-priced 200ml concentrate with an easy-to-measure doser for general houseplant feeding.

At £4.99, this is the lowest-priced option here. The 200ml bottle comes with a doser described as easy to measure, and it mixes with water as a general nutrient feed for houseplants. Its compact size makes it a smaller buy than the litre bottles, while still offering a straightforward way to add liquid feed during watering. It suits anyone who wants a low-cost bottle for a few indoor plants.

Best for a detailed formula

Growth Technology Houseplant Focus Concentrated Liquid Fertiliser, 1L

A 1L concentrate with clear mixing directions and a formula that includes kelp, humic and fulvic acids.

This 1L bottle costs £10.90 and states it makes up to 200L. Directions are clear: mix 5ml with 1L of water and use it every other watering. The formula includes kelp, humic and fulvic acids, giving it more named ingredients than most feeds here. It suits anyone who prefers measured dosing and a detailed formula, though the stated yield is lower than Bronte’s.

Best twin pack

Pack of 2 Baby Bio Houseplant Food, 175ml each

Two 175ml bottles of concentrate at £9.99, mixed a few drops at a time during regular watering.

This pack contains two 175ml bottles for £9.99, giving 350ml in total. It is a concentrated liquid, and the product details say to mix a few drops into water during regular watering. Having two bottles lets you keep one as a spare or place them in different rooms. At 350ml, the total amount is smaller than the litre bottles, but it comes as a handy twin pack.

Price£9.99Checked 6 Nov 2026, 17:00 UTC

Key Details

Pack size and yield: 2 × 175ml
Format: Liquid concentrate
How it is applied: Mix a few drops into water when watering

Best ready-to-use format

Growth Technology Houseplant Focus Drip Feeders, 10 × 38ml

Ten ready-to-use 38ml drip feeders at £10.55, with no measuring or mixing needed.

Unlike the concentrates, these are a ready-to-use nutrient solution supplied as ten 38ml drip feeders for £10.55. The product details mention humic acid and say the formula is urea-free. With no measuring or mixing, they suit anyone who wants a simple routine. The trade-off is volume: ten small feeders contain far less liquid than a 1L concentrate at a similar price.

Price£10.55Checked 6 Nov 2026, 17:00 UTC

Key Details

Pack size and yield: 10 × 38ml
Format: Ready-to-use drip feeders
How it is applied: Insert a feeder into the potting mix
Formula features: Houseplant formula with humic acid; urea-free

What We Like

Ready to use, with no measuring or mixing

Best overall

Bronte Concentrated Houseplant Food, 1L

A 1L concentrate at £10.99 with the highest stated yield here and a plant-based, seaweed-enriched formula.

This 1L concentrate costs £10.99 and states it makes up to 250L, the biggest yield figure in this group. The product details describe it as plant-based and seaweed-enriched. For the money, that offers the most stated volume of feed, and a concentrate keeps storage tidy. It is the strongest choice for value, though it does need diluting rather than being ready to use like the drip feeders.

Price£10.99Checked 6 Nov 2026, 17:00 UTC

Key Details

Pack size and yield: 1L; makes up to 250L
Format: Concentrated plant-based liquid
How it is applied: Dilute with water
Formula features: Seaweed-enriched formula

What We Like

Highest stated yield, up to 250L from 1L
Plant-based, seaweed-enriched formula

Considerations

Needs diluting before use
