Egmont Root Booster

$16.00 NZD

Root Booster from Egmont is a root fertiliser that give roots a potassium and phosphorus boost, in turn boosting above-ground growth, foliage and fruit production. 

This all-purpose root fertiliser can be used for indoor plants (ornamentals), as well as your outdoor garden, popular for vegetable and fruit trees.

This is the 250ml bottle, which makes up to 50 litres of root fertiliser once diluted. Recommended to get along with a 5ml pipette to make measurement easy (dose is 5mls per 1 litre water).


When to use Egmont Root Booster


Give as a spring booster if you haven't fed through winter, to get those nutrient levels fuelled up ready to power spring growth. Feed from late winter through mid spring then shift to your usual fertiliser.

Use to help establish the root system faster for baby plants and propagation once potted up, after separating seedlings, or after potting up cuttings after initial root growth has started. Feed for 2 to 3 weeks following potting up, then shift back to your usual fertiliser.


Directions for how to use Egmont Root Booster


Root Booster temporarily replaces your usual fertiliser. Dilute 5mls of Root Booster per 1 litre of water. For short-term use as intended, use every time you water to boost growth. When used for more frequent, longer-term use, it's recommended to dilute by half and use every second water. Intended for short-term use to boost growth, then to shift to your usual balanced fertiliser.

Water into soil
 as you would normally when your plants are due to be watered, or use as a foliar spray, provided the leaves will fully dry before exposure to direct sun, or when the plant won't be in full sun for at least 24 hours following foliar feeding. 

For plants with sensitive leaves, always do a test spray first when using as a foliar spray, the same as you should with any treatment applied direct to leaves, and wait 2 days before using on the rest of the plant to ensure no damage to foliage. 

For applying to soil, best to top water until water pours out drainage holes. This helps flush out excess minerals to avoid salt build-up, reducing the risk of fertiliser burn.

Root Booster

This has been a great product to use on plants I want to concentrate on better and bigger roots.
Has been great on some cuttings, that made the roots longer.

Egmont Root Booster

Really easy to use and my plants are already showing great improvement in their growth in just 3 weeks of use. My Monsteras minima, deliciosa and Thai Constellation have all popped out a new leaf since using the root booster, so they must be loving it too!
