    How and when you prune your hydrangeas is crucial to whether it will bloom. Some hydrangea should be pruned right after blooming; others can be pruned late winter or early spring. A common mistake is to look at those bleached out old branches after leaf drop and assume they are dead. Big mistake. Next year's blooms may be in those dead-looking stalks.

    If you don't know what type of hydrangea you have, don't prune for a year or tow and observe the plant's behavior: does is bloom on old wood (stalks formed the previous year) or does it bloom on current year's growth. Endless summer is a newish hydrangea that blooms on both old and new wood. It also requires more sunlight than older species.

    Without photos and more information on growing conditions and your soil fertility and water management it is impossible to give specific recommendations. But as a general tip, nutrient deficiencies may be responsible. It is important to keep up with fertilization and compost mulching.

    Is this an indoor plant? I'm curious as to how it is still in flowering at this time! If this is outdoors, or in an area that gets chilly then this is the issue. If this is an indoor plant, then I would pin the issue down to overwatering. If this is in container, then you should only water when the first few inches of soil are completely dry. This article will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/growing-hydrangeas-hydrangea-care-guide.htm

    Some hydrangeas bloom on new growth and should be pruned in late winter or early spring, before the shrub begins active growth.

    These include several varieties that have become quite popular: Limelight, Quickfire, Burgundy Lace, as well as the classic "snowball" types, such as Annabelle. PeeGee also can be pruned in late winter.
    Most of the other hydrangeas should be pruned in summer, once they have finished blooming. Most of these bloom on what's called "old wood" — growth from the year before. If you prune them in early spring, you risk cutting off the dormant flower buds. By pruning right after the blooms have faded, you allow the plant time to set buds for the next year. Examples of these varieties would be Oakleaf and bigleaf Hydrangea including Nikki Blue. Hydrangeas that are ever-blooming varieties such as Endless Summer actually bloom on both old and new wood can be treated the same and pruned in summer.

    This winter has had an excess of weather provoked gardening issues. There are commercial frost blankets but a folded bedsheet or double layer of row cover will help. (Try thrift shops for the sheets.) Another strategy is to block sunshine from reaching a tender plant on unusually warm winter days. That may delay further bud development. Often the bud survives further cold weather unless it has started to open. Best of luck.

    If it has leaves, keep your hydrangea inside until after your frost free date in May. At that time, harden it off over a week then plant it outdoors. Water weekly if rainfall is less than an inch per week all summer and fall. When temps are over 90, it may need water twice weekly. If your hydrangea is "bare root" it needs different care. Bare root plants are often shipped in fall for planting right away. However, don't try to plant while the soil is still very wet from winter snow and rain. I've included links to articles that should help.

    A hydrangea, as with most plants, will do fine with an all purpose such as that. Most will do their best with specialized ratios but a 10-10-10 is a good start for most things. Start with half strength twice as often if you want to test how your plant responds before going full strength.
