How can i get big flower heads on my hydrangeas?

Forced Hydrangeas can bloom in April and stay in flower until September. Overwintered plants won't bloom until summer.Choose a cool, light spot or on the patio in the shade of other taller plants. The temperature should not be much over 68%F in the summer. Give only enough water to keep the plant from drying out in the fall and winter, but water daily after the first flower buds have appeared. Add 2 grams of sulphate of ammonia per quart of water until it has finshed flowering. Water twice a day if it is very hot. It will thrive best in a mixture of potting soil and sphagnum, which should be well drained and with a pH of less than 7.


Try experimenting. Take pink flower heads and stick them in a pot of acidic soil with a pH of about 4.5 - 5.5 (the soil should be at least half sphagnum) and see what happens. That's right-blue flowers! This blue color can be strenghtened by adding a teaspoon of aluminum sulphate every 14 days. Make a mark on your calendar - the timing must be exact.


If more flowers are desired on the hydrangea you should pinch them out just above a well-developed pair of leaves. Continue doing this until the end of July. Cut the flower heads off just after they have finished flowering.


(sphagnum is a type of moss that grows in wet, boggy acidic areas, whos remains eventually become compacted with other plant debris to form peat)
