Hi everyone firstly no rants about slugs in this post) I bought some plugs of geraniums about ten days ago and potted them on into 3" pots. I used seed compost No.2 with a mix of vermiculite in it. The lower leaves turned yellow about four days ago and now this morning most have shrivelled up and turned brown...the top of the plants look green and healthy but lower leaves have gone and died on me:/ what have I done wrong??? It's all 20 of the plugs not just a few.........the geranium seeds I've raised myself are great..healthy, a bit smaller than the shop bought ones but alive any idea what I've done to them? (they're in a light position all day in my lounge in front of patio doors).
