The Mystery of NPK

Posted: 14/03/2014 at 19:41

As promised, I’m starting this thread to compliment Mike’s excellent ‘The mystery of pH’ thread. I’ll keep it as simple as possible, otherwise it with develop into a chemistry class.

 Basically NPK is:  N=nitrogen P=phosphorous and K=potash, the three main food elements necessary for plant life. Nitrogen is required for foliage growth, phosphorous for root growth and potash for growth of flowers and fruit.

 These elements can be applied in chemical or organic form…..the latter being preferred by most gardeners and the former mainly used by commercial growers.

 Although there are several types in there chemical form, the most common available to us gardeners being, Sulphate of Ammonia = N (nitrogen) Superphosphates = P (phosphorus) and Sulphate of Potash = K (potash)

 For an example, blood, fish & bonemeal  (a favorite amongst gardeners) offers these properties.  

 Dried blood is a slaughter house by-product and is an excellent source of quickly available organic nitrogen, when used as a top dressing or watered in. Dried blood completely soluble and can be mixed with water and used as a liquid fertilizer.

 Fish meal is a great natural fertilizer, high in phosphorous and high in organic nitrogen. Fish meal is quick acting, offering a sustained supply of nutrients.

Bone meal is used as a long-lasting source of phosphorous as well as low levels of nitrogen, potassium and calcium. The extremely slow availability of nutrients from bone meal makes it a very safe fertilizer, especially when planting of potting very young or new plants.

I wouldn't mind starting a similar thread about NPK, if there was any interest.

 ....further to my previous post, I'm posting this pic to show how the pinching-out process has encouraged new shoots to grow from the base, thus bushier plants.

PS. Two plants in the pot and the new shoots are the paler green ones either side.

Morning, Tracy & Louise.

Louise - Tracy is quite right, I posted pictures of the nipping-out process on page 24 of this thread.

Please don't worry about me having to repeat myself.....it really doesn't bother me.

Book/leaflet, not sure about that.....there people in the sweet pea growing fraternity far more able & qualified than me.

I have a large hazel hedge at the bottom of my garden and snip a few twiggy bits from that.....perhaps put your secateurs in your pocket, next time you walk the dogs.

Good luck for the weekend, Tracy. Don't be disheartened by your present SP efforts. it was always going to be difficult without even the basics.

Btw, 'twiggy bits' are,  erm just bits of twig pushed into the soil around the plants to stop them flopping over.

Hi, pinkquartet....This thread is rather long now, so I can understand if anyone misses things I have posted. However, I did post a piece on cordon growing on page 23.

I would imagine (if the soil is workable) they could be planted out now.......try to protect against cold winds until they have become established.

 Just a flurry really, but it was a pretty little location.
