Why do my flowers always die?

what have you tried growing? What time of day are you fertilizing? How often do you water?

By any chance are you planting near a black walnut tree? If so, nothing survives because it is poisonous to plants.

You might be buying the wrong type of plant for what you want. Annuals will die off every year, so you might want perennials which will come back year after year. You might be putting shade-loving plants where there is too much sun or sun-loving ones where there's not enough shade to grow well. Some plants just don't grow much or have a short flowering season. Another possibility: some plants are often sold at the very height of their blooming season, which can mean they're already starting to fade when you put them in the ground. If you think this might be the case, look for the ones you love in full bloom but buy the ones that are still in bud.

Have you had your soil tested? Do you use a water meter? What is the PH of the soil and water? Many people let the water they are going to use sit out over night. By doing that you let some of the chemicals evaporate out of the water. Are the plants getting the type and amount of sunlight they need? Plants for your zone?

Your soil may be too acidic. Ask someone at a local garden center what flowers they recommend for your area

Tip on planting annuals, make sure you are selecting the proper flowers for sun and shade.Let them establish a few weeks before applying fertilizer,water in the early morning ,when watering annuals make sure you are getting down to the root system, make sure if in pots they have drainage holes.

There are a couple of evergreens that cause this also but my brain refuses to recall the names, lol. What is your soil mixture, please, Phil?
