Looking for Something Different

Try tropical plants. They germinate fast in a greenhouse and you will have something less pedestrian than Lupins and delphiniums.

I do recommend Peter White's shop as I have had a good germination rate and I think he has a sale on:

Extending Grass Area in garden

Posted: 28/10/2013 at 14:35

Can you post a pic as it would help?

10cm deep of topsoil compacted down, sand to level then lawn rolls should work. I said lawn rolls as it is a bit late for grass seed to germinate as we are weeks away from frosts, but might work.

Thankyou blairs I will look into this 

I did see a fan greenhouse heater in this months GW near the back page

Have a look on Amazon warehouse - they often have cheap electric fan heaters with thermostats for half price. I would say it cost about £20 more to use it last year and that was with those late frosts James!

I would only say it was cost effective if you already have electricty in the GH of course as it costs loads to instal with trenching etc.

You can get Z shaped clips that you screwdown to seal polycarbonate glazing AJK.

Greenhouse Heating

Even if there was such as thing as solar powered heating, for 3-4 months of the year daylight duration, angle and strength would render it useless. The coldest period is 3am-7am in winter. On Dec 21st it can be daylight only from 9am-4pm, so solar will never work.

If you mean some sort of heat exchange using water warmed by the sun, then again the above with the added complication that the water will freeze to some extent.

An electric fan heated with a thermostat set to 7C is probably the best value given that paraffin produces so much moisture and you can kill more with botrytis than cold.

Bird of Paradise not flowering

They like being pot bound, so perhaps you are being too kind to the Strelizia. Do you know what variety it is? Am guessing it is not Nicoli.

Close the doors, windows, vent. A gust in the right direction has the parchute effect and the whole thing can explode. I have seen that happen to soild metal greenhouses. You are advised to site greenhouses in sheltered spots for a reason.

What to do with a Datura

The pic looks like a Brug - you cut them down Dove to the main stem and they regrow quickly in spring. They can stay in the conservatory or make them go dormant over winter. A 3 foot one would be best barely watered in a conservatory. Repot, feed and water,feed,  water, feed, water in the summer. Did I mention they like water and feed in warm weather? They are thirstly plants. A lot of pests like thier leaves, though they are poisonous.

Datura and a Brug are different:

I know little about Datura but I can advise overwintering Brug's
