Potting mix
Plants
1 ‘Double Zahara Yellow’ Zinnia (Zinnia marylandica)

1 ‘Hot Pink’ geranium (Pelargonium)
1 ColorBlaze® ‘Lime Time’ Black Dragon (Coleus)
Aftercare — Keep deadheading the geraniums, and you will enjoy more flowers through the season. Geraniums are perennials, although they are often grown as annuals and disposed of at the end of the summer. However, it’s possible to overwinter them for planting again the following spring. There are various ways to do this, but the most practical one, especially if you only have a few specimens, is to plant them in individual plastic pots and keep them in a light, well-ventilated, frost-free place. Make sure the plants aren’t touching each other, too. Water sparingly (the best time is in the morning) when the plants show signs of wilting, and ensure the water can drain from the pots.
Tip — Many people love coleus for their foliage and think they look their best before flowering, so pinch off the flowers when they appear if you wish.
