Adding a greenhouse to my garden is the best thing I've done. It instantly gave me more growing room, especially when it comes to starting flowers early and growing veggies. But, I've quickly learned you can't grow absolutely everything in a greenhouse – in fact, there are some plants that should be avoided at all costs.
It can be easy to get lost in the hundreds of beautiful greenhouse ideas out there, but it's important to remember the aim is to make it a productive space, as well as an aesthetically pleasing one. From fast-growing annuals to cool-season crops that just don't get along with the warmer temps and limited room of a greenhouse, it's best not to waste your time (and seeds) trying to grow them here – you'll just end up with dying seedlings and struggling plants.
