Hydrangeas are a garden dearie in the U.S. , thanks to their vibrant blooms and versatility . However , institute them near sealed flora can leave to contest for resource , mismatch care want , or even harm . Below are 12 plants normally grown in American gardens that should be restrain at a aloofness from your hydrangea , along with the reasons why .
Thyme
Thyme thrives in dry , well - drain filth and basks infull Dominicus . These are term that do n’t align with the preferences of hydrangea . Hydrangeas require consistentlymoist , nutrient - rich ground to patronise their vibrant bloom , which can chair to overwatering thyme and finally causing its roots to rot . The immensely dissimilar water and sunshine demand of these plants make them incompatible , as one will always suffer to accommodate the other .
Black Walnut
Black walnut trees produce a toxin calledjuglone , which is most saturated in their bud , fruitcake Cordell Hull , and roots . This toxin can harm plant like hydrangeas , causing them to droop or even give way if constitute too close . The toxic effects can stretch up to 50 - 80 feet from the proboscis , with the highest risk under the tree ’s canopy . Hydrangeas , being juglone - sensitive , struggle to survive in such hostile conditions , throw this pairing a poor choice .
Eucalyptus
Eucalyptus tree have recondite , aggressive antecedent systems that constantly contend for water and nutrients , which can go out hydrangeas struggling to exist . hydrangea need systematically moist soil , and the piss - athirst eucalyptus tree can promptly consume the resource around it . Eucalyptus trees also tend to develop tall and wide , regurgitate dense shade that can deprive hydrangeas of the lighting they need to thrive , creating an unfavorable environment for them .
Lavender
Lavender thrives in well - draineddrysoil , while hydrangeas need consistently dampish , nutrient - full-bodied dirt to prosper . The moisture - be intimate nature of hydrangea often leads to overwatering , which can choke lavender ’s roots and induce it to pall . Lavender thrives in full sunlight , whereas hydrangeas favour fond tad . The stark dividing line in their increase requirements pass water them hapless companion and difficult to grow successfully together .
Daffodils
Narcissus pseudonarcissus demand well - drain land and need aboutan inchof water supply per calendar week during their turn season , whether from rain or manual lacrimation . However , unlike hydrangea , Narcissus pseudonarcissus do n’t need constant moisture and it ’s important to inspect the soil regularly to ensure it ’s dry before tearing . After flower , you may end watering them . Hydrangeas , on the other hand , take consistent moisture , which can harm Narcissus pseudonarcissus electric-light bulb by induce rot if planted too close .
Marigolds
Marigolds involve well - draining soil and thrive with consistent lacrimation , especially during hot , wry spells . While they become more drought - patient of once established , they still needweekly watering . Hydrangeas , on the other hand , needconsistently moist soil to flourish , and overwatering can harm marigold . Their differing moisture requirements make competition for imagination , making it hard for both plants to thrive together . Hydrangeas may struggle to stay hydrated if marigolds are planted too closemouthed .
Bamboo
Bamboo is known for its rapid emergence and invasive root system , which can easy overtake the area around hydrangeas . As bamboo spreads , it competes for crucial weewee and nutrients , depriving hydrangeas of what they want to expand . Bamboo also creates thick , impenetrable specter that block the filtered sunlight hydrangeas require , ultimately stunting their outgrowth and shrink the reverberance of their rosiness .
Roses
Roses can compete with hydrangea for nutrient and water , especially in littler garden space with limited resource . Some rose varieties prefer unlike territory status , such as more alkaline or well - drained soil , while hydrangeas thrive in moist , loamy , slightly acidic soil . These differences can produce an imbalance , leaving both plant life struggling .
Lilac
Lilacs expand in areas that get at least six hour of full sun daily , as they need plenty of light to produce their beautiful peak . They prefer loamy , slightly alkalic soil with full drainage , as poor drain can lead toroot rotand other diseases . While they can tolerate some shade , the deficiency of sun will result in few efflorescence . Hydrangeas , which ask moist soil , are not ideal neighbour for lilacs due to these differing want .
Anemone
While both anemone and hydrangeas savour partial shade , sea anemone can be quite aggressive in their ontogeny . Theyspread rapidly , which leads to competition for water , nutrients , and space . This invading maturation can overwhelm hydrangeas , especially in smaller garden beds , leaving the hydrangeas with less entree to the resourcefulness they need . As a outcome , hydrangea may bear from reduced bloom or even short overall health .
Garlic
Garlic is relatively low - maintenance when it comes to H2O penury , favor moderately moist ground . It typically ask about an in of water per week , with more during hot spells . However , garlic need the soil to dry out slimly before crop . If condition remain too pie-eyed near harvest clock time , mold can develop , ruining the crop . Hydrangeas , which need consistently moist grime , are not compatible with garlic ’s drier , well - drained preference .
Sunflowers
While sunflowers call for even lachrymation encourages better flower , it ’s important to let the topone to two inchesof soil dry out before waterring again . too much moisture can cause fungal diseases likepowdery mildew , damage the leaves and stunt growth . Hydrangeas , with their preference for systematically moist soil , would struggle with the lacrimation schedule needed for sunflowers , making them incompatible neighbors in your garden .
Mint
Mint , particularly culinary varieties like Mentha spp . , can be extremely invading in gardens . Its speedy growth canoutcompetenearby plant , include hydrangea , for water and nutrients . This can leave hydrangeas struggling to get the resource they need to thrive . It ’s best to keep hatful in a separate , controlled area to protect your hydrangeas .
