Help with growing seedlings on

[SereneHighnessPrincessTheresa]

I have planted cosmos, sunflowers and bunny tail grass and they've germinated. I have tiny green shoots for the grass and two tiny leaves for the cosmos and slightly larger leaves for the sunflowers. What do I do next? The sunflowers are already in individual pots but the others are just in trays of compost.

Also another question are ornamental grasses all one plant or are they multiple plants in one pot?

The leaves on the Cosmos and sunflower are cotyledons or seed leaves, designed to keep the plant ticking over while it develops roots and true leaves. Many plants have a pair of seed leaves - this group is called Dicotyledons or dicots for short.

Another group (including most bulbs, orchids, grasses and similar) are monocots, with only one cotyledon. So each of your separate green shoots is an individual grass plant.

Leave everything to continue growing until the first true leaves have developed. Then you can separate them out into separate pots. Stems will be very brittle, so I always handle them by their leaves.
