greenhouse pests

Hi, I have just finished building my greenhouse and am growing, corn, tomatoes, cucumber and some cellery, but I keep reading about pests in greenhouses, would I expect a serious problems if I stick to growing vegetables and an unheated greenhouse.

 

Giving it a good clean in the autumn I use a cap full of bleach in the water brings the glass up and kills all the algie growth keeps on top of it, only had to fumigate once bad infestaition of red spider mite but did have a lot of hibiscus and cucumbers that year.

Unheated I would imagine you would have less problems

Actually, I quite like the smell

Not sure about growing Sweetcorn in a greenhouse though?

 

I've still got my pest - and I think it's a mouse! Out of 24 healthy tomato plants, I've only got eight left. And that's after it demolished the broccolli and cauliflower seedlings.

I've set a humane trap, baited with peanut butter, but now sign of the little varmint yet.

The surviving toms are now on a table and, fingers crossed, are so far unscathed. I want to transplant them into growbags but daren't yet. Little insects are the least of my problems!

 

We live and learn, I thought corn was from hotter countries so would do better under glass, guess I was wrong, I shall plant outside next year.

Thank you all for the advice on pests.

 

Well the mouse/shrew is caught. Sadly, although I used a humane trap, I didn't get to him in time and he is no more.
Poor little mite, I hadn't wanted that fate for him, despite the damage he did. Just didn't check the trap soon enough.

 

Hi I grew several swift sweetcorn in a large tub in the greenhouse last year but shifted it outside just before it was too tall and it did well. I did have a few nats invade the too of then before I moved it but once outside disappeared. I have planted sundance the same way this year so hoping it does well too. We have high winds here so it just gets damaged if I put it out too early. Speaking of bugs/nats I read somewhere that putting sand round my peppers and other plants prevents nats etc laying eggs in the soil, does anyone know if this is true please? Thanks

 

I I think any barrier of sand gravel will help with Gnats , in all my shrub pots I use a gravel a good inch deep which stops the vine weevils , used this one begonia pots as well and works 99% off the time , plus it help them from toppling over

 

Thanks I put in sand and it seems to be working
