    This sounds like a nutrient issue! Too much nitrogen, and not enough phosphorus and potassium can cause this. Alternatively, too low of a pH can cause this.

    A lack of flowers on the plant is often an indication of insufficient sunlight. To ensure consistent blooming, it is essential to plant salvias in an area that receives full sun, about 5-6 hours a day. Insufficient watering can also cause reduced blooms.

    A late or patchy frost can kill hydrangea flower buds or stems. You should also last fertilize with a slow release fertilizer 3 months before your average date of first frost; otherwise, the plant may be in grow mode when early frosts arrive and these can kill the flower buds. Too much nitrogen in nitrogen rich fertilizers may also reduce or eliminate blooms. Be mindful that hydrangeas like yours develop spring 2023 flower buds in the summer. They also break dormancy in stages: new spring stems grow first and leafless stems may leaf out as late as the end of spring in late June. Consider winter protection if the plants are always having difficulty blooming in spring.

    Since both are failing to bloom well, it could be a nutrient or pH imbalance. Mainly, you will want to test for your nitrogen, potassium, and phosphorus levels in your soil. During active growth, your feeding should be a little higher in nitrogen. During the bloom period, phosphorus and potassium will be higher. The first thing to do will be to test your soil for any deficiencies and pH swings. This article will explain in more detail:

    Unfortunately, this can be due to many factors, and to make things more complicated, it can depend on the type of plants in question. Mainly, when there is a lack of potassium and phosphorus in the soil, this can happen. But it can also happen if there is too much nitrogen, or the pH is not in balance. It can be due to specific fruiting conditions for specific plants, as well. Since I do not know the plants in question, what I could suggest is have your soil sampled by your local agriculture extension. They can give you an accurate reading of your soil, you can adjust accordingly.

    This article will help you understand a soil test, and what they test for:
