Look for a fertilizer that is high in potassium (K) and phosphorus (P) but low in nitrogen (N). Potassium and phosphorus encourage bud
growth and flowering. to prevent lush bushes with few blooms. Check your NPK (nitrogen-phosphorus-potassium) levels in your fertilizer
before you buy. Expert growers recommend formulas like 5-10-10, 10-20-20 or even 0-0-10. Fertilizing dahlias just a couple of times can
make a big difference to the flower crop. Add at planting and no more than once a month before flowering begins.
