Hard plants to grow from seed

Posted: 01/11/2013 at 09:23

I forgot to mention that some seeds need their outer coating damaged before water can get in. That is one reason why sowing on a gravel  path often works. Rain rubs the seed against the gravel and abrades the coating.

I had some seeds which the advice given was to soak them for a few minutes in mlld sulphuric  acid to emulate the digestive process. I did not bother sowing them.

Mine are fastened directly to the brick base. You just need to be a bit careful that either drilling the holes or putting the screws into rawlplugs in the bricks does not split the brick. This happened to me, but it was easy enough to replace the brick.

The one thing I did not go into is the question of germiantion inhibitors. These are present in the seed and are there to keep the seed alive and dormant until the optimmum time for germination. Some of them need cold to break them down, some need moisture and some just need time. Some need a combination or all or some of these.

The question is, why should any seed be hard to germinate? After all the plant is trying to preserve its genes and producing a seed which will not grow is counter-productive. surely?

The difficulty lies with us, not the seed. Lots of reason why that might be though. Non-viable seed is the most frequent. Some plants just cannot produce a viable seed under condtions in Britain. I have one plant which only produces seed which will grow only after a very very hot Summer.  Lack of suitable pollinators is another.

Some seeds have a very short life span, Hepatica, Anemone, Salix and such like.

Others need sowing conditions which are hard to provide. For example they need the germination inhibitors removed by the passage of the seed through an animals digestive system.

There are lots of other factors which some into play too.

So what did I do wrong this time...???

plants are inside a plastic balcony greenhouse which is inside the house at a south facing french door..

That is far too hot for cuttings, they need to be in light shade.

Sorry, got called away when doin this. Meant to add that either Perlite or Vermiculite is as good as sand/grit. Thanks for reminding me punkdoc.

There are some lilies which form roots before they have a leaf above ground.

Epigeal germination means above ground and hypogeal means below ground. Then to go with them there is immediate and delayed emergence. Look them up for a full explanation.

Most hardwood cuttings root well in the garden, in a sheltered, shady spot where the soil is well drainedby not dry.

Otherwise, all the cuttings need is something they can stand up in, where they can get enough moisture and which is not too compacted. They do not need food. So, half peat, half sharp sand/grit would do fine.

Don't forget that the inside wood in any tree is dead. The only part of the trunk which is live is the cambium layer just under the bark. Indeed, many Oak and Yew trees do better once the inside has rottted away.
