How To Care for your new Nikko Blue Hydrangea

When planting your Nikko Blue Hydrangea be sure you have the right location and conditions for your new plants to thrive. Spring and Fall are ideal times to plant Hydrangeas.  Avoid planting hydrangeas in summer when temperatures are mid80s or higher.

The Nikko Blue Hydrangea requires full sun to part shade and prefers moist, well-drained, fertile, acidic soil.  In hot climates, hydrangeas will do best with some shade.  If you have alkaline soil, be sure to amend your soil to maintain the deep blue color.  To acidify your soil, amend with compost, elemental sulfur, or use fertilizers specific for acid loving plants.  Mulching with pine straw or pine bark will help over time as they begin to break down, they will naturally add acidity to the soil.   Keep the soil moist, but not saturated, especially in summer and in the first year after planting.  Throughout its life Hydrangeas will do best with a deep watering once weekly during hot temperatures.  Mulching at about 3 inches deep is highly recommended for hydrangeas.  Mulching will cut back on watering needs and protect your plant in extreme temperatures.  Choose a slow release fertilizer for acid loving plants.  Fertilize once in spring after the last chance of frost and again in early summer for best results.  You don’t need to prune hydrangeas, but pruning after they are done blooming can help encourage a bushier growth and renew an older plant.  

The best way to prevent disease and pests is by providing the appropriate care for your plants.  Proper location choice, watering, and fertilization are the keys to your success. You can treat mites, scale, whiteflies, and aphids naturally with neem oil or insecticidal soap.  For severe infections you can use pesticides like carbaryl, also known as Sevin.  Fungal infection can be prevented by making sure the planting site has good drainage and by avoiding overhead watering.  Fungal infections can be treated with a fungicide.  Generally, treating fungus after infection isn't effective so if you have problems with other plants or in a prior year, treat preventatively in early spring.  


Planting Directions

Step 1:

Unpack all of your plants right away! Look for the perfect location. Make sure you are planting in the correct light conditions.

Step 2:

Dig a hole twice the width of the root ball. Position your plant in the hole. Make sure the top of the root ball is slightly higher than the original grade of the bed. Also check to make sure it is straight from all sides.

Step 3:

Fill up hole with water before placing new plant in hole in order to saturate the surrounding soil.  Once the water is absorbed place your plant in the hole and water thoroughly.

Step 4:

Mix the potting soil and the soil removed from the hole. Start by backfilling soil around the root ball. Carefully pack in the soil to remove any air pockets. Water plant thoroughly again until the soil will not hold any more water. This will ensure that your new plant will be a success.

Step 5:

Fertilize around your plant with the amount recommended on the package. Our special Fertilizer contains all of the nutrients to keep your plants growing and healthy. Repeat every 3 months.

Step 6:

Finish up by mulching around your new plant.  Apply 1-2 inches of mulch around the plant and plant bed. Mulch will help keep the soil moist and keep weeds out.

Step 7:

Keep watered with a hose every 2-3 days for 2 weeks. This is critical for plant survival. In the third week, begin to water as needed depending on the weather. Always check by placing your finger under the mulch to see if the soil is moist.

Best deal around!
I ordered 2 of these hydrangeas and I was very surprised by the size compared to the price. I looked on other sites that were much more money. There were well packaged and quite large. I will be trying more from this company.

Classic look
We ordered our Hydrangeas for the Charleston house after we received the HOA bi-laws. Our delight was instant. When they arrived they were bursting out of the box! Beautiful.

When does it bloom?
A shopper on Dec 7, 2016
BEST ANSWER: Once this hydrangea is established, it will begin to bloom early summer.
Other hydrangea bushes are okay in zone 4 conditions. Would this really not be a good choice for Penobscot County, Maine?
L Jean B on Nov 20, 2016
BEST ANSWER: This particular hydrangea is not recommend for zone 4. It may do ok, but most likely it can freeze out.
