Cultivated plants cannot live on water alone, and the soil they are in can only provide them with so much nutrients. Just like humans taking vitamins, plants need a little nutrient boost too, but in the form of fertiliser. Without fertilisers, plants will grow weak, be poor in colour, and have a lack of flowers and fruit. When fertiliser is added to a plants diet, the plant will not only flourish, but will be stronger and better equipped when pests and diseases try to attack.

The main nutrients in Hydra WonderGrow

There have been three main nutrients that dominate the formula of plant feed for many, many years, and Hydra WonderGrow contains all three, which are Nitrogen (N), Phosphorous (P) and Potassium (K), also known as NPK.

Nitrogen helps to boost the green growth within plants. The foliage. Not only this, it helps with the development of new shoots. If a plant is short of nitrogen, growth will be stunted, and leaves may start to turn yellow.

Phosphorous is essential to encourage germination, root growth, and helps to improve a plants ability to take up new nutrients.

Potassium encourages and influences the production of flowers and fruit within plants, meaning an increasing chance in pollination and better crops than those grown without fertiliser.

When Hydra WonderGrow is fed to plants, all the elements from NPK work in sync and help each plant flourish to the best of its ability, helping you to produce plants to be proud of.

How to use

Shake well before use. Add Hydra WonderGrow first, then water.

As Hydra WonderGrow is a liquid plant fertiliser concentrate, you have different options on how to apply your feed:

Handheld spray bottle – If you have houseplants or herbs, you can mix your solution in a handheld spray bottle and mist your plants with feed.

Watering can – Mix your solution in a watering can with a rose attachment, and shower over your plants.

Pump sprayer or large sprayer – for larger plant beds and areas, you can mix your solution in a pump sprayer or large sprayer and spray to apply.


When to use

Like all fertilisers, regardless of whether the plant lives indoors or outdoors, it is best to apply Hydra WonderGrow during active growing months as all plants need growth to slow down in the cooler months; fertilisers will break this cycle if used all year round. We recommend starting your feed in March, as this is when temperatures start to rise from those of winter months.

Do not feed plants in cold, frosty weathers or in hot, dry summers. When applying plant feed in the summer months, apply this in the coolest part of the day, whether that be first thing in the morning or late at night. We also recommend only using feed once a week, anymore and you may overwhelm and overwater your plants, which may cause them stress resulting in burnt and scorched looking leaves, to deteriorate or even die.

Can I use this with my indoor and outdoor plants?

Yes! Hydra WonderGrow is designed for plants found indoors and outdoors.

Is this good for vegetable growth?

Yes, Hydra WonderGrow contains all the nutrients needed for a healthy boost in growth when growing fruit and vegetables.

Can this help my sunflowers grow taller?

Hydra WonderGrow contains Nitrogen (N), Phosphorous (P) and Potassium (K), also known as NPK, which will give your sunflowers a better chance of growing taller with a stronger stem.

Can I use on roses?

Yes, you can use on all plants found in your garden and home.

How often should I be applying this to my plants?

We recommend following the watering guide of your plants as some plants like to be watered little and often, others weekly or fortnightly. But we recommend not applying any plant fertiliser more than once a week.

Best time to start using this?

Within the growing months. Do not feed your plants in winter months as they go semi/fully dormant in winter. We recommend March – October.

Will my fruit and vegetables be safe to eat if I use this within the water?

Yes, this will not affect the edibility of your produce and will be safe to consume.
