San Diego Real Estate Voice : Hydrangeas Can Change Color

Hydrangeas Can Change Color

When I selected my own Hydrangeas, I wanted the Blue Purple variety. While I was reading up on them to learn how to care for them, I discovered that you can actually control the color. Allow me to add, this is true only sometimes, because where they are planted can have a strong affect on the color as well. You can better control the color when you raise the Hydrangeas in a large garden pot. 

Using Aluminum Sulfate in the soil of a potted Hydrangea will tend to make the flowers more blue or purple. Using a fertilizer high in phosphate will tend to make the flowers more pink. 

Take those same plants and plant them in the ground near a sidewalk and you will notice that even if you start out with blue colored plants, they will soon turn pick. The lime from the concrete leaches into the surrounding soil and it has a higher Ph and that changes the blue flowers to pink. 

Garden centers sell fertilizer for both generating the blue color and for generating more pink tones. If you happen to be blessed with a white variety, don't bother trying to change the color because white stays white to a pale greenish cast forever. That is what Mother Nature intended and she doesn't take too well to being messed with. 

I recently bought a new Hydrangea for a large pot and the first thing I did was to remove the flowering heads ( deadheading) and then started to add some used coffee grounds to the soil.  That tends to lower the Ph which helps offset the high calcium content of our water. That was 4 weeks ago and the new growth is just amazing. The plant, when it finishes growing out with the new growth will be about twice the original size. Before Fall sets in, I expect to have some large beautiful Blue/Purple blooms. I will be sure to show them here when the blooms come out.

William- ok, I'm pea green with envy!!!!   Purple is my favorite color and those are beautiful.  I'm not sure if we can grow hydrangeas in Florida but I may try.

How about that? I did not now you could somewhat change ( or preserve ) the color! Thanks William.

Hi Kathy, I think you can. Start with raising them in pots.

William

I have always really liked hydrangeas - so much more common back in New England - in all the different colors. I certainly learned more than I ever thought I would know about them from your post.

William, We get a lot of used coffee grounds (for free) from Starbucks for use with our azaleas.  Same basic deal, controlling the ground acidity to keep them healthy.

Note to Kathy 

Go on-line to buy them. You will tend to get stronger plants than trying to locate where you live.

We save the grounds starting in early Feb and mix them around the bases of our hydrangeas. The colors are brilliant

Good morning William. I love hydrangeas and have been pretty lucky with them. I had various colors in my former home and they were healthy and big. Working on them here now.

I knew a lot of this as I'm always looking for mine to be blue/violet as that's the color of my house. But I must admit I get a bit lazy about doing it.

William-I did know about the ability to chg their color but I still learned more from reading this. Thanks for sharing your wealth of knowledge. I have I think 4 hydrangeas. They are small right now and haven't bloomed yet

William, we don't have hydrangeas here but I did know about the ph causing the color changes.  Quite an interesting phenomena.

Hydrangea are my favorite flower.  When we bought our first home in  1980 we transplanted some from my in-law's home.  We took some with us when we moved to our second home and than again when we moved into our current home.  I hope to always have them wherever I live.

We have them here and my aunt is a color genius. She has blue, pink, green, white and a lovely lavender....she mixes the additives and makes them really amazing.

Hydrangeas are my very favorite and I also think they do better with a sandy soil.  I always notice that ones in a beachy area are stunning.

They are beautiful and fairly simple to keep alive and pretty.  That's my bonus with them.  I do not have a green thumb.

William,

Yes, they can, and I love how they do that.  I had some outside our breakfast nook in LA.  They are a beautiful plant.  A

William- ok... I have tons of coffee grounds, and I'm going to look online.  Thanks for the tip.

William - I always use my coffee grounds on my plants--roses thrive on coffee grounds as well.

My mother loved Hydrangeas!  I learned early on about their changing color.  I remember that my dad had a friend, who worked in a metal shop.  Dad would often bring home the metal shavings and put them around the base of the plants, to keep them blue. Hydrangeas definitely have a mind of their own when it comes to color!

William, lovely picture and yes, you reminded me of my Biology lessons way back....lol!

Good morning William,

I'm so glad I read Kathy's Sunday post and caught your post as one of her favorites for the week. I can certainly see why..I love hydrangeas and never knew you could help change their colors!! Great information and will be looking for your post in the fall when your plants bloom!

We have oak leaf Hydrangeas and I just live the white- every year people come over to cut and use in their wedding center pieces- don't think I will be experimenting on changing their color anytime soon.  Thank you for the information William.

William, I've been having terrible luck with these beauties.  I'm going to try it your way.

Thanks to you and Kathy I'm getting quite an eyeful and an earful of great information.  I'll be looking at the soil a lot closer next time I see these colorful beauties. 

Posted by Kevin J. May, Serving the Treasure & Paradise Coasts of Florida (Florida Supreme Realty) almost 5 years ago

This is good information. Hydrangeas are popular in our area and I see several colors during my photowalks through the community.

Posted by Roy Kelley (Realty Group Referrals) almost 5 years ago
Hi Roy, I wanted the Blue color for the pot that I have on the patio. But I will say, the varied colors are really quite wonderful and for most, the beauty is in the variety of colors they produce without to much interference with the selection of the fertilizer.
Posted by William Johnson, Retired Real Estate Professional (Retired) almost 5 years ago

I knew this about Hydrangeas too and also love the beautiful blue violet ones.  I did not, however, know that about coffee grounds!  I just met with my landscaper about my new house garden and added some Hydrangeas - absolutely one of my favorites!  Now I know how to get those thick, lush leaves!!

Hi Debe, In the very early  Spring after any chance of frost has passed, be sure to deadhead the plants and then add the special aluminum sulfate and you will be so pleased with the results.

Posted by William Johnson, Retired Real Estate Professional (Retired) almost 5 years ago

Thanks William!  I will give my hydrangeas some coffee grounds before they bloom this season to see what happens!  I just love them!  Such hardly flowers and a late summer offering.

This past winter was really hard on some plants and a few friends of mine who have hydrangea commented on how this spring they had to cut the dried stems from last season. Unlike some winters before that were mild, the dormant stems often rebounded with green shoots, but not this spring.  New shoots only came out closer to the ground. Maybe the blooms will be more glamorous because of the hard winter!

Hi William Johnson - Those are beautiful flowers and I am sure they are going to get even better and more healthy.
