If people use compost for starting seed off in a greenhouse - do they
use general purpose compost or "seed planting" compost? Does it matter? |

I use seed compost to sow seeds and then prick out into general purpose compost which I find is far too coarse for seeds. Judith |

It's important to use seed compost because it won't over feed your germinating seedlings. Some/many seedlings won't even germinate in ordinary compost and as my husband says, "don't save pennies and waste pounds". -- Sacha http://www.hillhousenursery.co.uk South Devon 'We do not inherit the earth from our ancestors, we borrow it from our children.' |

Yes and part of gardening is, of course, its failures, too. It's all part of learning. I think everyone has to push the boundaries a bit to see what works for them. Years ago, I read a book in which the author described how she'd asked someone to clean out the stables, intending the manure to be heaped up and left to rot down a bit. As we are all told, fresh manure direct onto plants is supposed to 'burn' them. Well, to her horror she saw her helper had put the manure straight onto her flower beds, inches deep and she was terrified all her plants were going to be killed off. In fact, they thrived and grew wonderfully. Whether that sort of thing is a question of luck or not believing all you read, I don't know! -- Sacha http://www.hillhousenursery.co.uk South Devon 'We do not inherit the earth from our ancestors, we borrow it from our children.' |

On that basis, should we feed a baby on watered milk for the first few months of its life, as it will no doubt develop a more efficient digestive system? Unless a plant has a specific need for a certain soil type (eg Proteacea) why not start it off in JI3?

FWIW, I had a similar experience, spreading stuff I had received from my local bull stud farm. It was much, much fresher than I expected, and the only thing to look bad after I spread it was a pieris, which I thought was evidence of burn by exceedingly fresh muck, but I later discovered would have been happier in a pot with ericaceous compost - where it thrives now. The rest of the bed, which had been middling until then, just took off in the year that followed!

It is true that some of them are well adapted to poor soils such as heathland, but is it assumed that they would not tolerate the extra NP and K in JI3? Or is it that the same price is charged for a bag of Ericaceous compost as for JI3? Sulphur must be pretty expensive, then, compared with the other (missing) ingredients. -- Jeff (cut "thetape" to reply) |

I think that plants growing in ericaceous soils are better able to access plant nutriants (but not some minerals like iron) than those growing on alkaline soils so my guess would be that the nutriant levels do not need to be as high for the same results. As for the cost, it could be more to do with where the loam comes from and the transport cost involved rather than the fertilizers put in. -- Charlie Pridham, Gardening in Cornwall www.roselandhouse.co.uk Holders of national collections of Clematis viticella cultivars and Lapageria rosea |

With regard to seed compost use, why should any plant prefer a "poor" start in life to a "rich" start? Probably not the richness that affects the seedlings, more the balance of ingredients affecting drainage/water retention. On a commercial scale you would not want to pay extra for added fertiliser in your seed composts when the seedlings don't need it. But on a domestic scale, it may be cheaper to just use your general compost instead of buying a mini-bag of seed compost. And if all you actually want is two or three plants, it doesn't really matter whether you get 100% success from your sowing. On that basis, should we feed a baby on watered milk for the first few months of its life, as it will no doubt develop a more efficient digestive system? You shouldn't pad out its milk by adding cereal ;-) A lot of the advice to new mothers in recent years has been on the lines of delaying weaning and not over-feeding in the early months. -- Kay |
