Tangled Greens Liquid Kelp is a biostimulant made from kelp sustainably grown on the West Coast of Scotland. High in potassium, it improves resistance to disease and protects the plant when the weather is cold or dry. The unique range of nutrients and growth hormones found in kelp strengthens root and soil systems and prevents wilt, which is great for fruits, vegetables and flowers.

Application: For best results, direct watering is recommended. Application rates and frequency will differ depending on soil quality and plant variety. 

  • Ingredients : Kelp (Saccharina latissima)
  • pH: mildly alkaline 
  • Shelf life: 12 months from opening 

Please Note: Liquid Kelp has a strong natural odour produced by the kelp as it breaks down. Gases are a normal by-product of this process and may cause the bottle to expand - to release these simply loosen the cap. Fertiliser appearance may vary slightly between batches. Use within one year of opening for optimum results.

The Basics

Ideal soil

Acidic soil, good organic content, pH 4.5-6.0. Inkarho range of rhododendrons will tolerate soils up to pH7.5

Sun or Shade

Light dappled shade is best for most varieties.


Refer to hardiness rating. Give young plants protection.

Site Selection

Avoid close to trees, roots, invasive weeds, walls, hot patios, dry banks and waterlogged soils. Do not use weed matting or stone mulch.

Plant spacing

Use the height shown in 10 years as a guide to the distance between each plant. Allow room for plant to fill out. If planting closer for instant impact, be prepared to move plants after a few years.


  • 3 litre pot, dig in 10-20 litres of ericaceous compost.
  • 7.5 litre pot, dig in 20-30 litres of ericaceous compost.
  • 70-80cm specimen, dig in 60 litres of ericaceous compost.
  • 100-120cm specimen, dig in 120 litres of ericaceous compost.

Planting depth

Plant high in the ground, with the top of the rootball visible.


Slow-release ericaceous feed recommended in March and straight after flowering.


Recommended every few years.


The key ingredient! Keep moist all season, especially the critical time at end of June for flower bud initiation. Tap water is better than no water. Heavy dose at least once per week in dry weather.


Ensure good drainage in winter, especially with yellow flowering varieties. Avoid waterlogged sites.


Rhododendrons and Camellias: Not normally required. Tidy wayward shoots after flowering.

Evergreen azaleas and Bloombux can be clipped into a low hedge.

Magnolias and Acers: Formative pruning when young to shape into a tree or bush.


Remove old flower-heads, particularly on young or weak plants.
