Will baking soda turn hydrangeas blue?
If you’re not sure what kind of soil you have, you can make an easy, homemade test using distilled water (which has a neutral pH), white vinegar (acidic), and baking soda (alkaline): Just follow Garden Therapy’s simple instructions here. The color change won’t happen overnight, but it will happen.
How do I get my hydrangeas to turn red?
If you need to nudge your soil farther along the line toward alkaline to get your hydrangeas as red as possible, add lime. Adding dolomitic lime or agricultural lime increases the soil’s alkalinity. Sprinkle 1 cup of lime around the dripline of each shrub. Do this in spring and again in fall, watering it in well.
Do coffee grounds change the color of hydrangeas?
Some gardeners report success in turning their hydrangeas blue by applying coffee grounds to the soil. The coffee grounds make the soil more acidic, allowing the hydrangea to more easily absorb aluminum. In addition, fruit peels, lawn clippings, peat moss and pine needles, are thought to have a similar effect.
Will vinegar turn hydrangeas blue?
To increase the acidity of your garden’s soil, use vinegar! For each gallon of water in your watering can, add one cup of white distilled vinegar and pour on your hydrangeas. The acidity of the vinegar will turn your pink hydrangeas blue or keep your blue blooms from turning pink.
What to add to the soil for hydrangeas?
You can use a variety of organic materials to amend soil for hydrangeas. Homegrown compost, bagged compost and composted manure are all great choices. You may also find excellent regional sources of organic matter, such as cotton hulls, ground fir bark or dried seaweed.
How often should hydrangeas be watered?
It’s better to give the plant plenty of water a few days a week rather than a little every day. And make sure you keep the flowers dry when watering. On warm days it’s best to water early in the morning or in the evening. This is when the plant is ‘resting’ and can absorb the water best.
Are banana peels good for hydrangeas?
Banana peels also make a great fertilizer for hydrangeas. Use the peels from two or three bananas per plant. Chop the peels into small pieces and bury them around the base of each plant. Using banana peels as a fertilizer for your hydrangeas will also help to repel aphids.
