Urban Gardening Tips on Growing Zinnias in Containers

These are my first zinnia blooms. I never thought zinnias can grow this lovely under our tropical weather here in Manila.   Both the pink and corral zinnia varieties have grown so well and have blossomed generously.

I planted them from 2 packets of seeds which I bought about three months ago.

Zinnias generally don’t like to be transplanted.  I sowed my seeds directly in elongated 8-inch deep plastic containers, filled with potting soil that I mixed with some slow release fertilizer pellets.  The seeds germinated in about 3 – 5 days. In about 6 -8. weeks, the flower buds started to appear.

Zinnias grow best under full sun. They need at least 6 hours of sun everyday. They are relatively easy to maintaIn. Water them only as needed, as they don’t want to be soaked.
