Questions About Hibiscus Plants

    A newly planted hibiscus will be sensitive to its environment not being perfect so give it a break until it becomes established in the garden. Once established with a much larger root system, it should perform better. Here in Texas, they are very drought tolerant through out normally very hot summers from May through September. They can be found planted in the medians of many streets.

    Other possibilities:

    Too much or too little water. Wwhen recently planted, maintain the soil as evenly moist as you can during the growing season.

    High heat.

    Too much fertilizer.

    Check for thrips (very small, slender dark insects). If you find any, spray with either a water (1 gallon) + soap (1%) solution to suffocate them or you can use spray neem oil.

    Check for gall midge and its eggs/larvae in the flower buds. The buds can fall off when the gall midge fly lays its eggs in the buds. The larvae is white. If you find larvae or eggs collect all fallen buds in a plastic bag and dispose of the bag in the trash. You can also try applying insecticides with the active ingredient imidacloprid but the spray may not reach eggs/larvae in unopened flower buds.

    Some cultivars are self-fertile, and some are not. It could be very likely that yours is not.You will have to find out which cultivar that you have and see if it can self-pollinate.

    Otherwise, you can ask the place that you purchased the plant from.

    Here is an article that will help you to grow the shrub:

    Pictures would help. Consider powdery mildew (a fungal disease), white aphids or mealybugs (cousins of aphids).

    They need to be deadheaded to prevent going to seed. This article should help:

    Hopefully soon. Hibiscus syriacus begins flowering in mid-to-late summer in New Jersey (the time depends on the specific variety; NJ publications generalize the time to 'mid to late summer or later') and continues until frost. Down here in Texas, our summer starts in May and you can see this hibiscus bloom starting in June-ish. Do not apply too much fertilizer or the excess nitrogen will cause no or few blooms. Also consider these other problems: dense shade, too much water, soil deficient in phosphorus (for example, in sandy soils) and garden pests like aphids.

    Newly purchased hibiscus can be sensitive to new surroundings so give them a break until they become established in their new location. Water adequately if temps are hot, fertilize as needed and provide 6 hours of sunlight or more. Test the soil regularly to detect when it is dry; some potting mediums will lose moisture faster than others. Look for thrips, aphids, mealy bugs, spider mites too as these insects can cause bud drop.
