    You can start pinching the tip when it reaches your desired flowering height. Just pinch the tip enough to fully destroy it, while leaving it attached. This will force branching lower down. You can pinch at anytime you feel it is large enough for your taste.

    It sounds like they are a bit too moist. They need to dry out between waterings. In fact, they prefer dryer soils once they are mature.

    Be sure to let them dry out a little between watering, and treat with a fungicide.

    It looks like you are using topsoil in your container. This doesn't work well for many plants; consequently, potting mix (no soil included) leads to much better growth.

    Neem oil is safe for beneficials but predatory insects are the best way to deter whiteflies, some of which are available at the local garden center.

    It isn't that they won't bloom, though some might not. It is more that they won't be anything like the parent flower. There is quite a bit of genetic variation and hybridization in modern cultivars.

    If you want some true to seed, you will need to look into planting heirloom varieties. They will, usually, breed true.

    Here is an article that will help you to care for the plant: https://www.gardeningknowhow.com/ornamental/flowers/zinnia/growing-zinnia-flowers.htm

    If you have had rain, AND are watering- Yes, it has been very overwatered. The soil needs to dry completely to about 3 inches in ground before it receives water, ideally.

    Overwatering will, first, suffocate the roots. This will lead to infection, which is what you are seeing now.

    There are a few things that will need to be done, but it probably won't correct the issue this yea. It will help with the next planting, though.

    First, I recommend treating with a fungicide/bactericide. There is a lot of overlap and it can be difficult to pin down an exact ID of the pest, so a fungicide is a better option if you do not not the pest in question.

    I would recommend, most of all, a biofungicide. This is another group of microbes that will fight for your plant in the soil. They can, also, help prevent future infections. This article will help:

    Once the soil has been treated, you will have much better success, even during the rainy seasons!
