Q.When Will Flowers Come Out
Planted some kind of Hibiscus (Arden’s Althea) last year. There are many buds but no flowers. Same thing happened last year. Do I need to do anything for this to start flowering.
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.
