Bulbs, corms, tubers etc.  These are all self contained.  Never mind when you obtain them.  For the time being.  Pot them up and treat them as if they were planted in the garden.  Time will tell.  Then you can transplant to the open ground.

Steve.  Please don't misunderstand me.  A good suggestion but in reallity.  From a scientific point.  Reflected light although it might in some instances tend to solve or aid a problem. In this case, it would be no different from shining a torch onto the growing area.  To the majority of mankind.  Sunlight is a source of illumination and at times a giver of warnth.  Believe me, far to complex to deal with here and now.  Suffice to say.  Sunlight not only provides what we might call the basics.  It also carries with it multitudes of valuable other elements that help to sustain plant life and human life.


I do hope that I haven't offended you.  Kindest regards. Mike.

Need advice on very small, boring garden!

Posted: 26/03/2014 at 23:02

Oh dear!  No offence intended but why I ask.  Why do people who have the benefit of a garden, however small.  Why cover it over with timber?  From the pics.  It appears to me taht even arond the timber, there is very little room to move.  Poor old you.  You obviously would like to see some colour and enjoy some flowers.  Container grown plants would feature nice standing on the decking.  Also a an eye catcher.  Some table displays of alpines.  Truly there are so many possibilities.

Believe me, despite all that I am supposed to know.  I ghave had this sort of thing happen to me.  Lets be honest.  For you to prick all those seedlings out into pots.  You are going to need a lot of space.  Will you trust me?  Take your time over this.  Geta few more seed trays, or cell trays.  Either way.  Make sure the compost is well watered and drained.  Then gradully prick out and transplant to the new trays, planting just that little bit deeper, just so that you could slip the average plant label  between the underside of the tiny leaves and the compost.  Gently firm in. Preferably use a bottle sray or whatever to gently spray the whole tray.  You see.  At this stage, the seedling stems/stalks etc have not as it were toughened up enough to withstand too much water.  A fine mist-like spray will help to protect and at the same time provide enough moisture to sustain the tiny seedling.  See how it goes.  Keep in touch.

A hoe is a very handy toool in the garden.  It saves on the back bending etc.  As our friends have described it cuts the weeds down.  Always remember, work backwards.  That way you don't end up literally shovelling heaps pf soil and weeds forward.  The Dutch hoe can also be used for maintaing a fine tilthe amongst plants and shrubs.  Held similar to the way the old road sweepers used to hold their brooms.  Hands close together at the end of the shaft.  If you are right handed.  Then rest your right hand against your chest.  Left hand just below the right, gripping the shaft.  Short stabbing movements will cause the blade to just puncture the soil, at the same time a gentle twisting or flicking movement on the shaft will work wonders.

Additional pH ratings.

Hi.  I have almost completed a short list of the pH requirements for a selection of greenhouse plants and those often kept indoors as house plants.   Please keep an eye open for the list.  I do hope that the lists will at some time be of use to you.

Well done.  From your pics.  Might I say.  They are looking good but advancing a wee bit too fast, also I suggest that you turn the trays around.  Or introduce some auxillary lighting. So as to straighten them up.  Due to the rapid growth.  You might need to plant them a wee bit deeper when pricking out.  In which case, go very easy with the watering, as the tiny stems will be subject to damping off.  Keep us informed.  We will all help as much as possible.

Polycarbonate Greenhouse Spares?

Posted: 26/03/2014 at 22:22

Sadly, this is a problem with metal framed greenhouses.  I much prefer wooden frames.  Might I suggest.  Ebay, simply type in, greenhouse fittings etc.  Then sometimes Wickes carry a stock of bits and bobs.  Also your local garden center, finally  The manufacturer of your greenhouse or a polycarbonate supplier.  Hope you soon get fixed up.
