What’s best: Multipurpose, Potting, Seed Compost?

Posted on

New to gardening? Confused about which peat-free compost is best for you? Here we explain the differences between our Soil Association-approved multipurpose, potting and seed compost.

Peat-free seed compost

Ideal for seeds and cuttings, this is a mixture of organic coir, vermiculite and Fertile Fibre nutrients.

The coir – made from coconut husk – is great at encouraging germination and fast rooting. The small specks of white and gold vermiculite help control watering. So there’s no need to worry about over-watering. If this happens, the  vermiculite will soak up the excess. It will then slowly release the water as the compost dries out.

Tips on using seed compost

You can use the compost straight from the bag.

  1. Place it in seed tray or pot. Be ver careful not to over compact – simply tapping the container on a hard surface is enough.
  2. Place seeds on top.
  3. Cover with the same depth of compost as thickness of seed. So if seed is 1 mm thick, cover with 1 mm of compost.

Don’t over-water. Coir has excellent water holding capacities so this can be a problem. We recommend watering little and often. The compost may seem dry on top but will still be wet underneath, so it’s always worth double checking before watering.

Multipurpose peat-free compost

An excellent all round general use growing medium. In our compost, it has the same ingredients as our seed compost. But there’s less vermiculite and more nutrients. The nutrient levels are low enough for germination and high enough for established plants.  It’s a popular choice amongst our customers growing crops such as wheatgrass for juicing.

Potting peat-free compost

Plants in pots and containers need more nutrients as they can’t draw up anything through the soil. Our blend is a rich, dark mix of coir, vermiculite, bark, loam and our unique organic nutrients.

Potting compost helps ensure strong, vigorous, healthy and  sustainable growth.

Tip: Use it as a growbag

Many of our customers just use the bag as a growbag and plant directly into it.

  1. SEEDS
    We use ONLY Fertile Fibre Seed Compost for all our seeds. We get uniform germination and there is enough nutrient to keep the seedlings going if we are a bit late pricking out!!

    For raising cuttings we use sieved potting compost and then add a medium grade vermiculite. The ratio of sieved compost to vermiculte varies according to the cutting material, but is typicaly 3 parts sieved potting to 1 part medium vemiculite. This gives a more open rooting medium than the straight seed compost, which suits our mist propagation system better.

    We use the professional grade potting compost for virtually all our potting on. For the majority of plants we use it “straight”, ensuring it is well fluffed up and not over compacted ( I cannot stress the importance of this enough!). For lavender and rosemary we mix 2 parts potting with one part of “ballast” (the stuff you get from a builders’ merchant) or sharp sand, this gives the really sharp drainage these plants need and reduces the nutient levels to promote better flowering.

    The results – our customers say they have never seen such healthy plants!

  2. i am growing tomatos in my green house for the first time using the autopot system—-I have purchase from you 120 ltrs of perlite. I have been recomended to mix the prelite 50/50 with compost. What do you recomend
