Incrediball Hydrangea (Hydrangea arborescens Incrediball) is a stunning native hydrangea shrub, and a bit of a prodigy. It is an improved version of Hydrangea Annabelle that doesn't flop even after a rain due to its super strong stems. If you're looking for a native hydrangea that produces giant 12-inch white blooms, you’ve found it. Incrediball Hydrangea bloom time begins early June and lasts all the way until August. A mature Hydrangea arborescens Incrediball can produce up to 80 large flower clusters on a single shrub. This flowering shrub is known for its long lasting blooms and is a favorite for cut flower arrangements.

Incrediball Hydrangea shrubs are much better left to grow in their natural, rounded form rather than being pruned for hedge-use. When you buy your 3 gallon Incrediball Hydrangea online, try to keep it out of shade and make sure it gets at least 4 hours of direct sunlight every day.

Planting Information

Before you buy an Incrediball Hydrangea shrub, make sure to read about the care instructions that are required and recommended to keep this plant healthy and thriving.

When should I water my Incrediball Hydrangea?

When should I water my Incrediball Hydrangea?

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Incrediball Hydrangea a good deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example a one gallon pot would be watered until you count to 5 a three gallon pot would be 15 and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks. Gator bag Jr. can be used to help aid in this process and also provide plants with a good soaking due to the slow release of the water into the root-zone of the plant. Soaker Hoses can also be used to water when planting a long hedge.

When should I mulch my Incrediball Hydrangea?

When should I mulch my Incrediball Hydrangea?

We highly recommend that you mulch your Incrediball Hydrangea with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away which will compete with your new investment for water and nutrients. A 2 to 3 inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch. Its better to leave a one inch gap of space between the mulch and the stem or trunk of the plant.

When should I fertilize my Incrediball Hydrangea?

When should I fertilize my Incrediball Hydrangea?

Incrediball Hydrangea grows best if it is fertilized once or twice in the summer. Although some authorities recommend special fertilizer mixes to get the maximum results, hydrangeas do amazingly well with a more relaxed approach. Apply an early spring fertilizer with a product such as Espoma Tree-tone or Plant-tone at the recommended rate this will give the plant a boost of nitrogen that will be needed for healthy abundant foliage. Follow this up with a early summer application of Espoma Plant-tone, this will provide the necessary nutrients and raise the nitrogen in the soil which hydrangeas favor. Espoma products are easy to use, just sprinkle around the base of the plant and water it in. Be careful with products such as miracle-grow as these products can burn newly planted plants when not used at the recommended rates. Slow-release fertilizer can help prevent rapid sucker growth that is vulnerable to diseases and insects. Either chemical fertilizers or organic matter can be used successfully. Since an organic method of applying manure and/or compost around the roots produces excellent results and also improves the condition of the soil, this would be an excellent first line of attack. Organic additions to the soil can also be combined with a shot of chemical fertilizer for maximum effect. If chemical fertilizers are used on your Incrediball Hydrangea shrub, applying a slow-release, balanced fertilizer once a year is probably the simplest solution. There are many slow-release fertilizers on the market. If you can find a fertilizer formulated for shrubs and trees, this fertilizer would work well on hydrangeas. However, slow-release is certainly not the only way to fertilizer hydrangeas such as Incrediball Hydrangea. A less expensive fast release fertilizer such as a 10-10-10 will work just as well if applied twice during the summer. If you are looking for a fertilizing routine tailored to your specific conditions, a soil sample should be taken and the fertilizer and trace elements matched to the needs of your soil. Don’t fertilize Incrediball Hydrangea bush after August. Fall is the time for hydrangeas to begin preparing for dormancy. Fertilizing at this time may stimulate new growth that will be too tender to withstand the winter. In the South, a late May application and another in July would be about right. More northern areas may wish to fertilize only once in June or July.

How should I plant my Incrediball Hydrangea?

How should I plant my Incrediball Hydrangea?

We suggest when planting your newly purchased Incrediball Hydrangea plants that you dig a hole twice as wide as the root system but not deeper. Depending on the quality of your existing soil you may need to add a locally sourced compost or topsoil to the back-fill soil. We do not recommend using straight topsoil or compost as a back-fill soil because more times than not these products will retain entirely to much moisture and will cause the root system to rot. Adding compost or topsoil will help the young feeder roots of Incrediball Hydrangea to spread through the loose, nutrient rich soil, much easier than if you used solely the existing soil which more times than not will be hard and compacted. The most common cause of plant death after transplanting is planting the new plant to deep. That is why we do not recommend planting in a hole any deeper than the soil line of the plant in the pot. A good rule is that you should still be able to see the soil the plant was grown in after back-filling the hole. Bio-tone starter fertilizer is a great starter fertilizer that provides plants with mycorrhizae fungus. It is a naturally occuring beneficial fungus that colonizes on the new growing roots of plants. It creates a barrier between the roots of the plant and fungus and pathogens that can cause root rot. We love this product and use it on all plants we install in our own gardens. Bio-tone is a gardeners best friend and can help guarantee your success.
