Start early with the summer flowers
One of the advantages of having a greenhouse is that you can start the summer early and plant cold-sensitive flowers and plants long before they can tolerate being outside.

If you just can’t wait for the summer flowers, you feel like many others. Even though the rule of thumb says you should wait to plant until after the 5th of June, it is a rule that can be bent – at least if you have a greenhouse.
The warm climate inside the greenhouse means you can enjoy the summer flowers way earlier. In our greenhouse, we have planted geraniums and harebells in small clay pots. Those small pots usually dry out fast in the heat, but they are placed on a shelf with under-irrigation. It is therefore not much work to irrigate, as you just pour water in the shelf.
