Geranimum plugs

My geranium plugs plants are looking like they need to go into the garden for potting. However im concerned its a little early (frost). They are quite big and fully formed. What do you advise as i dont want to loose them.

It's too early to plant them out yet - I'd keep them in an unheated greenhouse for a couple of weeks yet at least if you have one. They can also stay indoors in your house.

Also, pot them on into a slighty bigger pots, this will give their roots room to expand and provide them with a boost of vital nutrients until the last frosts are over. When the right time comes to plant them into your garden they will be healthy and alot bigger in size.

Thank you Alina W and Marshmello.
