Groups of plants
Hello there. This is my first post as i can usually find the answers to my questions whilst lurking in the background. I'm a fairly new gardener and have received an order of perennial plug plants and potted them up and will probably pot them on again for planting out in July. I ordered two packs as i didnt think they would be much cop but they look really healthy so now i'm wondering if i've bought too many. So, my question: when i look at the description it gives height and spread of each plant, like digitalis height 50cm, spread 40cm. Do i have to plant each individual plant that far apart or do i just pay attention to the spread of the type and plant them in groups closer together?
Also as we are having nice weather can i leave the new plants outside in the sunshine during the day or are they still too wee for that?
Thanks in advance for advice given
