The flowers don't require removal, or deadheading, to continue blooming, but pruning off the old flowers does improve the plant's appearance. Deadheading can also prevent hollyhocks from unwanted self-sowing so they don't spread to nearby garden beds.
Pinch off any blossoms from the main stem that have begun to fade to improve the appearance of the plant. Leave the stalk in place so the remaining buds can open and flower fully. Check the hollyhocks every one to two days once the flower stalks are blooming and remove dead flowers.
Cut off the entire flower stalk at the base after 70 percent or more of the flowers have finished blooming. Use sharp shears to remove the flower stalk.
Dispose of the deadheaded stalks immediately. Stalks left in the garden bed may harbor disease organisms that can spread to the plant.
Cut down the entire plant in fall after it dies back. Remove all parts of the plant from the area.
Maua hayawezi kuondolewa, lakini kuondoa maua ya zamani kunaweza kuboresha sura ya mmea. Deadheading pia inaweza kuzuia hollyhocks kutoka kutaka kujitawanya hivyo hawawezi kuenea kwa vitanda vya bustani karibu. Punguza maua yoyote kutoka kwenye shina kuu ambayo yameanza kufifia ili kuboresha sura ya mmea. Acha shina mahali pake ili matawi yaliyobaki yaweze kufunguliwa na kuchanua maua kikamili. Angalia hollyhocks kila siku moja hadi mbili mara moja shina la maua linapochanua na kuondoa maua yaliyokufa. Kutoa shina la maua kwenye sehemu ya chini ya shina baada ya maua ya maua ya 70% au zaidi kumaliza kupasuka. Tumia kisu chenye ncha kali kuondoa shina la ua. Tupa vipande vilivyo na vichwa visivyo na vichwa mara moja. Vipande vilivyoachwa katika kitanda cha bustani vyaweza kuwa na viumbe wenye magonjwa ambao wanaweza kuenea kwenye mmea. Kata mmea wote wakati wa vuli baada ya kufa tena. Ondoa sehemu zote za mmea huo katika eneo hilo.
