June 29, 2011Q.Hydrangeas Not Blooming
I planted blooming hydrangeas last year. They were beautiful! This year the plant is looking very healthy, but it is June 29 and no blooms on either of my hydrangeas. They are planted in day sun and afternoon shade. The plants are on different sides of the house and still no blooms. I did not prune these last fall, is that why they are not blooming?

Certified ExpertA.The soil around the non-blooming hydrangeas may be lacking in phosphorus. That can affect the ability of the plant to bloom. These articles will help you learn more:

My hydrangeas are withered and look like they are dying. It has been close to 100 degrees, but I water them every morning. What can I do to save them? They have always been beautiful.

Certified ExpertA.Where are your hydrangeas located? They tend to perform best in partially shaded areas, especially in hotter climates. They do not like to be hot. You may need to transplant them to an area that receives afternoon shade.

July 5, 2011Q.Pruning Hydrangeas
I have two hydrangeas, which are planted next to each other against a wall. They were planted about 3 years ago. I think they are the type which should be pruned in late summer or early fall, but I am not sure. Let's call the plant, which is blooming well, plant #1 and the one which only has one blossom this year, plant #2. Plant #1's blossoms start as green and turn a deep purple. Plant #2's blossoms (I think) started out as white and then turned blue. Late in the fall for 2 years, I cut both plants back, only leaving about 6 inch stems. I now think this is incorrect. Plant #1 still bloomed well each year. Are these plants different types? Should plant #2 be trimmed as soon as the blossoms begin to fade, but no later than early August (I live in the Philadelphia, Pa area)? If so, wouldn't I be deadheading flowers? Can you help me on how to prune these plants?

July 6, 2011Q.How Do I Correct Fertilizer Burn?
The leaves on my hydrangea are turning brown due to over fertilizing. How do I correct this? Is it fertilizer burn? I used flowering plant fertilizer 15-30-15. I also changed the colour with Aluminum Sulphate. It has new flower buds forming. Should I just continue to flush the area?

Certified ExpertA.It could be fertilizer burn, but it could also be too little water. If your hydrangea is in full light, they are very water hungry and will brown on the edges or wilt during the day if they don't get enough light.
Flushing the area is the best thing you can do. It won't reverse the damage, but it will prevent any more from happening. Plus, if it is a water issue and not fertilizer burn, it will make the plant happy.
In the future, water a plant very thoroughly before applying fertilizer. This will help keep the plant from taking up too much fertilizer and burning its roots.

July 6, 2011Q.How Do I Keep Hydrangeas White?
My mom and I bought a beautiful white hydrangea in April. We planted it with compost soil mixed with regular topsoil. The blooms have turned green, and the leaves are curling. The temperature here in San Diego has remained cool (about 70 to 75 degrees). The plant gets at least 4 to 5 hours of sunlight. How do we keep the blooms white? The hydrangea is a big leaf with a large cluster bloom, sorry I don't have it's exact name.

July 8, 2011Q.Under-Developed Hydrangea Blooms
Live in Zone 5 and have a large leaf hydrangea. Every year the hydrangea develops numerous flower heads but only 25% of the flower heads actually develop into a full flower. The hydrangea is several years old. The plant is a foundation planting and faces north. It gets morning sun. The plant appears healthy and quite vigorous but never blooms fully.

Certified ExpertA.There are a few things that could be happening.
First, it could be the cold in your area doing it. If the flower buds develop while you are still getting even light frosts, this can kill the buds. Being on the north side of the house, you may even have a slight microclimate happening where the plant is experiencing light frost even when the rest of your yard is not.
Second, too little water may be the culprit. If the plant is wilting alot, this could be killing the flower buds.
It could also be a phosphorous issue. You can try giving it some bonemeal to see if that will help.

July 14, 2011A.Thank you for the helpful information. As an inexperienced garderner, I always thought my hydrangea was a mophead but it turns out that the plant is a lace cap hydrangea and it is blooming the way it is suppose to!
