Finding Good Companions
Good fellow plant can promote growth , serve with plague and weed control condition , offer shade for small plants , and improve dirt health . A honorable pairing , for representative , would be buckwheat and brassica . The Fagopyrum esculentum will serve keep weeds aside from brassica while draw helpful insects .
It just guide a snatch of research before you start imbed to bang which plants pair well . Celery , for case , can be planted with onions , love apple , and bean , as well as daisies and snapdragons , but does n’t immix well with maize , Irish Irish potato , or asters . Chivescan better the flavor of love apple and help keep aphids away , but they should not be set near edible bean and peas .
When you get companion planting properly , you’llboost the ontogenesis of vegetables , herbs , and flowers , and helpcontrol pestsnaturally . In this guide , you ’ll find 11 fellow traveler planting error to stave off .

Fennel with Most Herbs and Vegetables
When it comes tocompanion planting , fennel is one of the tricky works to work with because it does n’t get well with most plants . As it grow , common fennel releases compounds into the grunge that can suppress the development of nearby herbaceous plant and vegetables orcause them to bolt .
to boot , fennel can spoil - cross-pollinate with other related plants , like dill , lose weight the flavor and caliber of seeds . This can makegrowing fennelnear other plants a challenge ,
What to try instead : Grow finocchio in pots placed throughout your garden . When keep in containers , common fennel wo n’t impact the growth of other plant life , and its bloom will attract pollinators and other beneficial louse to your garden .

Bob Stefko
Brassicas , includingbroccoli , cabbage , andBrussels sprouts , are often targeted bycabbage measuring worm , which can riddle their folio with hole . Unfortunately , these nettlesome insects are n’t picky eaters , and they can devour other nearby fruit and veg works , too .
Specifically , strawberries that are grownnear brassica plants are much more potential to recrudesce cabbage measuring worm infestations . So , when you ’re looking for a maculation to place your strawberries , channelize clear of your brassica vegetables .

What to try or else : couple brassicas with garlic or onion , which dissuade brassica pests with their tone , or with beans and peas , which put atomic number 7 back into the soil . Strawberries do well alongside lettuce , spinach , and rhubarb plant .
Sage with Cucumber
Cucumber and sage just do n’t get along . The herb limits the maturation of nearby cucumber vines and reduces harvest home , too . Plus , sageand cucumbers have different lacrimation needs , so grow them in the same area will often result in overwatered sage or underwatered cucumbers .
What to try instead : Aromatic dillandoreganooffer a muckle of pest shelter to cucumbers , while short root vegetables like carrots or beets , alongside vining cucumber vine , will maximize garden space . Sage repels pest from nearby craw like brassicas and Lycopersicon esculentum .
Asparagus with Alliums
onion , Allium sativum , and other allium plants have a strong odour , which of course repels many garden pests . While this makesalliums great companionsfor most vegetables and herb , asparagusand alliums just do n’t mix .

Legumes with Alliums
In addition to Asparagus officinales , alliums also do n’t grow well with leguminous plant plants , includingbeansandpeas . When interplanted together , alliums can stunt the ontogenesis of leguminous plant works and reduce harvest return . What ’s more , onions and other alliums have instinctive antibacterial properties that may curb the nitrogen - fixing bacteria on the roots of legume plant life .
What to try instead : bean and pea get along well with lots of other crops , including cucumbers , eggplants , radish plant , and marigolds , which deter many common pests .
Corn with Tomatoes
Dean Schoeppner
Corn and tomatoes bothmake serious salsas , but these two plants are n’t good partners in the garden . tomato and corn are both vulnerable to corn whiskey earworms ( also known as tomato fruit worms ) , and growing these plant life together can make it easy for pests to spread throughout your crop . Additionally , edible corn and tomatoes are both cloggy - feeding plants , and they can contend with each other for nutrients in the soil .

Dill and Carrots
Dillandcarrotsare both phallus of the Umbellifer category , and they have similar rise needs . However , these plants are so closely related to that they can potentially cross - pollinate with each other and make poor - timber hybrid seeds . Beyond that , Anethum graveolens can attract carrot flies to your carrot , and these rapacious pestis chew holes in etymon veggie .
What to try instead : By warding off sealed pests , dill weed does well with brassicas , lettuce , and cucumber . Tryplanting carrotswith sage to guard off carrot rust fly or with radishes , which have exchangeable growing need .

Other brassica works , likecauliflower , may also not be the best selection for raise near grapevines .
Credit:Dean Schoeppner
What to assay instead : Grapevines do well with many herb , including thyme and rosemary . Try wampum with any of the many plants that repel cabbage worm , including alliums andcelery .
Potatoes with Tomatoes
Potatoesandtomatoesboth belong to to the nightshade family , and they can be susceptible to many of the same pests , includingtomato hornwormsand Colorado Solanum tuberosum beetle . Growing these plants together gain it loose for pests to move rapidly from plant to plant , bring mayhem on your edible crops and stripping your plants of foliage . These pesterer can even winter in the grease , so it ’s essential to rotate all nightshade crop on a three- to five - twelvemonth cycle .
What to try rather : Potatoes are fleshy tributary that deplete nitrogen from the soil , so they do well with beans or peas , which put it back in .

Turnips with Other Root Vegetables
Turnipsand other root veg like potatoes and radishes all conduct their growth to the same place — downwards into the land . So when grown together , they will fight for nutrients within the soil , ultimately result in small crops and yields for all of them .
