Scotts Osmocote® Boost+Feed Orchids

Easy to use, unique formula to provide orchids with essential nutrients for optimum growth and plant health, including potassium and iron for more beautiful blooms and greener foliage. Its double action works through the roots and leaves, so your plants absorb nutrients within minutes. 

  • Easy to apply with Easy Sprayer- no drips, no hassles - or by diluting yourself from the concentrate
  • Contains carefully balanced potassium, iron, trace elements and bio stimulants for healthier orchids that resist diseases and insect attacks
  • Ideal for all orchids in any situation including epiphytes and terrestrials in the ground or in pots
  • Perfect for when plants look tired or stressed or when an added boost is needed for fast growth

Liquid advantage

Provides an instant boost of nutrients through rapid root and leaf absorption for strong, healthy growth

Feeds soils and plants

Includes a blend of bio stimulants that build productive, vigorous plants with healthy roots

Use any time

Can be applied anytime of the year when plants are actively growing. Avoid using when temperatures are expected to exceed 30C

Hose-on or Concentrate


The 1L Easy Spray bottle is perfect for quick fertilising tasks and covers up to 180 m2. The no mess, no drips ready-to-use is perfect for orchids growing in the ground or epiphytic orchids attached to trees or other structures where a watering can is impractical



The 1L Concentrate is the better option for potted collections or difficult to reach areas where a watering can or pump sprayer may be easier to use. It makes up to 450L

Handy Tip

To determine the area you want to treat, multiply the length x width in metres. 1 long stride = approx. 1 metre

Leaf and root uptake

It goes to work immediately and is effective whether applied to potting mix, soil or leaves

Suitable for

All orchids including natives - it has a low phosphorus content

Not suitable for

Do not use on lawns - use only specifically named fertilisers on grassed areas

Do not apply to young orchid seedlings or other types of indoor plants.

How it works

  • It's boosted with bio stimulants that activate soil and potting mix micro-organisms, condition the growing media and enhance nutrient uptake

How to use

Easy Sprayer

  1. Shake the bottle well before attaching to the hose - ensure the thumb switch is in the OFF position first
  2. Tighten the hose connector on the handle prior to connecting the hose; turn the hose tap on
  3. Slide the thumb switch to the ON position to FERTILISE or slide to the WATER position to just water your orchids
  4. Use a sweeping action to evenly distribute the spray over the plants you want to fertilise (the bottle should empty in approximately 12 - 13 minutes
  5. When finished, switch to OFF position and turn the water off

When using the Concentrate:

  1. The 1L Concentrate comes with a measuring cap. Mix 2 capfuls in 9 litres of water in a watering can
  2. The concentrate can also be used in a pump sprayer. Use the same dilution rate as for the watering can
