Over wintering HELP
Last year I overwintered plug plants in a plastic greenhouse which I moved into the garage for extra frost protection.
OH says he is not happy to have plants in the garage as there is insufficient ventilation, causing condensation and consequent damage. I can't argue with that so I need a solution please.
I quite like the little glass and wood 'grow houses'.
But would a grow house be warm enough, when/why would I need a heater? When would I need to open/close the windows?
I don't want to spend too much (but birthday coming up), also bubble wrapping the inside of the plastic thing sounds fiddly.
I assume it will be too warm in the house (no consevatory).
I don't have a suitable site against a house/warm wall but have sheltered areas under trees.
I'm not sure when to use various products ; cold frame, greenhouse, cloche, fleece.
Please help me decide what to do and what to buy to protect the following plants.
2.allium hairy green (that's whats on the label!)
3. evening primrose
4.salvia hot lips
5.salvia patio deep blue .... I think this one is too tender for outside???
6. penstemon garnet
7.cerinthe kiwi blue (2"high with 4 stems, quite healthy at the moment, seed sown wrong time of year I think)???
8.eryngium (may already have been eaten by slugs or gone to sleep for winter,I can't tell which)
9. alstromeria psittacina 'Royal Star' --- This is my favourite, there have been no side shoots (only leaves) to take cuttings, the seeds don't seem to be drying out (still green). It has started to die back. it's in the ground so I was hoping to use a cloche bell but no idea really.
THANKS SO MUCH FOR READING ALL OF THAT AND FOR YOUR HELP AND ADVICE.
