calluna vulgaris
Any ideas what the ideal proportion of nitrogen, phosphorous and potassium
is for heaths and heathers. I've just purchased a soil testing kit, but it seems pointless testing the soil if I don't know the levels at which the plants require their nutrition. I've got the ph levels just about right now, but am unsure about what level of nutrition I should be aiming for. The first test shows that nitrogen levels are pretty low. I think that is supposed to be good for heathers - am I correct? Alex |

If the pH is about right for the ones you've got, just let the little devils rip in their own way, and they'll love you for it. Heaths and heathers occur naturally in rather poor environments, and require low levels of nutrients. Feeding them could result in weak sappy growth, when you want long-lived rugged specimens with short legs. You could set fire to the lot every few years if you wanted to reproduce their native habitat: not very horticultural, but it would release some potash, and the local grouse would be grateful for the new shoots! As you suggest, I _certainly_ wouldn't give them nitrogen if they're growing in anything vaguely resembling soil. The only time I'd consider actually feeding heaths and heathers would be if they showed clear signs of a specific nutrient deficiency. And I've never seen that (the books will tell you when). My best ericas have been in a bed consisting of mixed builder's rubble (to include bits of plastic and the odd end of Tanalised timber), Matchbox toys, a few coins, limestone chunks, and shale fragments stuck together with a bit of clay, and not much more. I watered them occasionally in their first year, then let them get on with it: I don't live there any more, but they're looking good up to twenty years later. The NPK is best saved for the vegetables and the shorter-lived flowering plants -- especially the ones we cut for the house, which of course involves taking something away from the soil. Plants want to grow, and they know more about it than we do. Amateur soil-testing kits are a waste of time and money. -- Mike. |

Heathers, especially calluna vulgaris, naturally live on acidic heathland, poor soil at the best of times. I had a heather garden for twenty years, never gave them anything and they grew perfectly well. If you must, use a natural slow-release nitrogen fertiliser such hoof & horn and just scatter it around. -- Chris E-mail: christopher[dot]hogg[at]virgin[dot]net |

Ericas are more tolerant of high pH than callunas-I would not recommend
limestone chunks for calluna vulgaris. "Mike Lyle" wrote in message ... Alex Woodward wrote: Any ideas what the ideal proportion of nitrogen, phosphorous and potassium is for heaths and heathers.
