Hard plants to grow from seed

Posted: 31/10/2013 at 12:35

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.

And very often what is hard for one person is easy for another. Take Hepatica, I cannot get it to germinate, even straight off the plant and into the compost,nothing. Yet a friend, doing the same as I do, gets it to come up like Cress.

 

Anyone know the name of this fruiting plant...?

Chaenomeles japonica comes in various shades of red, through to white, with both single and double flowers. C. speciosa. moerloosei is a pinkish orange.

The original Marmalade was made from true Quince. The name comes from rthe Portuguese for Quince, Marmelo. The Victorians changed it to Oranges as they are easier to process.

Any damage?

No more rain or wind here than in any normal Autumn.

Pruning Mahonia

You can actually cut them back to almost ground level, if you need to. The ones at Bodnant Gardens were really hack back a few years ago and they are back up to 6 feet already.

Since they are Winter flowering shrubs, pruning now would remove the flowers. The best time would be in April.
