Question. As spring MAY be arriving here, southern MD,

[elleng]

and my outside plants are showing signs of life, I'd like to know about feeding them.

Camellia has already blossomed, unfortunately many blooms took recent freeze and heavy winds rather badly, but it's a well-established bush.

Azalea is showing signs of life, new leaves, and hydrangea's new growth is very promising.

I also have 2 rose bushes, in large pots, with new growth showing.

Do I need different kinds of fertilizer for each, or is there one that can serve all?

Thanks!
