Many mintage of hibiscus plant or shrubs exist , some of which are repeated or brave and others aretropical hibiscusesthat are grown as yearbook or as houseplants in nontropical hardiness zone where winters consist of several months of subfreezing temperatures . hibiscus are very tight - growing plants , so splitting or dividing them at the rootage is an in force way to promote new and level-headed maturation and provide works with more room to spread out out .
Hibiscus Types
Tropical hibiscus are characterized by their dark - green , almost glossy leaf color and flowers in bright colors such as orangish , yellowed and red . These hibiscuses are not hardy in places where freeze last longer than a few hours . brave or perennial hibiscuses tolerate freezing temperatures , and with the exception of rose wine of Sharon , a variety of hibiscus that flowers off the previous year ’s woody development , these plants die down to the ground at wintertime .
Why Divide Hibiscuses?
Hibiscuses are tight - growing shrubs sleep together for their abstruse and extensive ascendent systems . distinctive indicators that plants need dividing include sparse foliage at the bottom of plants , bare spots in the center and fewer blooms and smaller flower . These are indications that the monumental root word ball is not able to provide sufficient nourishment to all parts of the plant .
When to Divide
The general rule regarding the division of perennial is that perennial that bloom in outflow and summer are divided in fall , and perennial that flush in fall are separate in spring . Most perennial require dividing every three to five years . hibiscus are a bit different because in warmer mood , brave hibiscuses can bloom from spring until frost , and in tropical areas , tropic hibiscuses ( Hibiscus genus Rosa - sinensis ) may bloom year - round . Ideally , you should not divide plants when they are flowering . Most perennial hardy hibiscuses bring forth new growth in spring , so the best time to divide them is betimes in spring just after the first Modern growth come forth . Because rose of Sharon ( Hibiscus syriacus ) plants develop newfangled growing and flower off the previous twelvemonth ’s woody stem , separate these plants in fall once they polish off blooming and lead off to enter quiescency . Divide tropical hibiscuses when they are not blossom or when dormant when grown as houseplants .
How to Divide
To split up hibiscuses planted in the terra firma , dig deep into the flat coat so you could withdraw the full root ball from the planting hole . Extensive root systems will in all probability render container - grow plant root or pot bound . pink the bottom of the smoke to free the rootage ball from the pot . Once the plants are out of the ground or container , spray the base ball with water to remove as much soil as possible . utilise a sharp pruning knife or hear to bring down the base glob into smaller divisions . set the freshly split up industrial plant sections immediately and pee deeply . Continue to water regularly to ensure that new divisions establish themselves .
