    Do the yellow leaves stay supple and remain on the plant? If so, then overwatering or improper drainage could be the culprit. Although they are thirsty plants (even more when it's really hot) you really have to be careful with them and especially if they are potted in plastic pots (the water doesn't evaporate out as quickly as it does in ceramic). Generally in summer I water in their pots every second or third day (unless there is intervening rain) and then I water well - so there is about 1/4 inch of water on top of the soil. After watering check back in about 1/2 hr to ensure that there is no water still on top of the soil and the pot is draining out of the bottom. Hope this is helpful Good luck

    The ants themselves are not a problem, but they are likely on the plant because of aphids, which can hurt the plant. The ants are attracted to honeydew, the sweet sticky substance that aphids and other sap-sucking pests leave behind. I would try treating the plant with neem oil, which is effective for handling these pests.

    The hibiscus flower normally blooms for only one day, opening in the morning and wilting by late afternoon. To compensate for this, the buds grow quickly and are opening all the time.

    How much detergent did you use? Too much can actually be detrimental to the plant. Most recipes recommend using two teaspoons of dish detergent per quart of water (or 2 tbsp to 1 gal). Depending on how long it's been since you applied the detergent and if it was recent, you could try hosing the plant down to offset the detergent effects. Adding some bone meal to the soil around your plant may help encourage blooming but otherwise, you may simply have to wait and see what the plant does.

    In the future, try using neem oil. I have found that nothing works better than this for controlling aphids. Here is more information on it: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

    It is possible that it is slugs. They will climb up the plants at night to eat the first foliage they come across. You may want to try Diatomaceous Earth around the base of the plant. It will kill any bugs or slugs that crawl across it. This article will also help with slug control:
