This is a tray of young Geranuim plants, which were bought as "Plug Plants", in other words, Plants that were delivered as small plantlets by post, in protective packaging. You just need to gently remove each one and pot them up singly.
The photo on the right , shows them after re-planting was done. Best not to overwater these young plants, as they tend to get a fungal disease, called "Botritis", which causes the stems to rot off at the base of the stem. The plants them die.
So just keep the plants moist enough and don't let them stand in water. Later as they grow, an Organic feed is recommended, like a dilutable Seaweed feed. Geraniums can be planted outdoors in early June, after danger of frosts has passed. Standing them outdoors in daytime till they harden off, but take them indoors at night.
