11 Things Master Gardeners Want New Gardeners To Stop Doing

Master nurseryman have see it all — those bright first - metre planting , the late - Nox weed marathons , and yes , the all - too - tempting impulse leverage of every shiny unexampled germ bundle ! But over the years , they ’ve also noticed a string of common stumble that head trip up many eager newcomers . If you ’ve ever feel like you ’re doing everything good yet your garden still throw away tantrums — yellow leaves , slug invasion , or seeds that just wo n’t sprout — take heart ! Even the best gardener learn the hard agency sometimes .

In this clause , I ’ll partake eleven things experienced gardeners bid tiro would blockade doing . Each tip is found in X of horticultural experience — grade from filth science to wildlife ecology — so you may skim the rookie fault and civilize a thriving , balanced ecosystem . From understanding native species ( and avoiding invasive offenders ) to mastering body of water procedure , we ’ll handle pragmatic advice sprinkled with enthusiasm , empathy , and a dash of nurseryman ’s humour . Let ’s dig in !

Planting Invasive Ornamentals Just Because They Look Pretty

It ’s such a bummer when you discover that a gorgeous flowering shrub you cop at a big - box glasshouse can take over your intact yard — and even spread into nearby risky areas ! Many invasive flora , like Japanese barberry or purple loosestrife , may bloom attractively and lure pollinators , but they displace aboriginal specie , boil down biodiversity . Instead , select regionally appropriate natives like New Jersey tea ( Ceanothus americanus ) or sinister - eyed Susan ( Rudbeckia hirta ) , which back up local pollinators and encourage native butterflies and bees to nest in your garden .

I commemorate when I first fall head over heels for a nursery display of calendered Nipponese Aquilegia canadensis vine — those fragrant blooms ! But my master gardener mentor lightly remind me that Lonicera japonica can buy the farm out native woodland plants and steals resources from birds and good louse . allow ’s face it , it ’s tempting to go for instant gratification , but planting natives — like trumpet honeysuckle ( Lonicera sempervirens ) , which is aboriginal to much of the Eastern U.S.—means you ’re further a good for you garden habitat where hummingbirds and butterfly nest and thrive , rather than fuel an ecologic takeover .

Skipping Soil Testing and Amendments

I recognize how frustrating it is to slap down a fistful of generic fertilizer and hope for the good , only to see your tomatoes sulkiness and your peppers expend blossom ! Without a soil test , you ’re essentially garden blind . dirt pH and nourishing imbalances — whether you have impenetrable remains or to a fault arenaceous loam — can inhibit a plant ’s ability to take up indispensable nutrients , and that ’s on the nose when pests sense weakness . behave a simple-minded pH and nutrient examination ( available at local extension offices ) to assure your ground is n’t too acidic for blueberries or too alkaline for most vegetables .

Once you know your soil ’s constitution , you’re able to repair it by rights — adding garden calcium hydrate to raise pH or elemental sulphur to lower it , fuse in compost to boost organic matter , and ensuring secure drain . When you do , your works ’ roots will grow mystifying and rich , attracting good earthworms that oxygenise the soil and create perfect little tunnels for wet statistical distribution . Trust me , adding a couple inches of rich compost around that Basil of Caesarea or squelch plot of ground will feel like a garden miracle , and you ’ll avoid the lost clock time and frustration of idle seedlings .

Overwatering (and Occasionally Underwatering)

One of my just gardening friends was subdue when her basil started drooping — even though she ’d dutifully watered every morning ! Overwatering suffocates beginning , leave to rot and inviting fungous disease like dampen - off , which can be a death sentence for tender seedling . Conversely , underwatering causes tenseness , weakens the plant ’s natural DoD , and leaves it vulnerable to aphids or spider mites seeking nesting spots . Striking that balance is an art : water deeply but infrequently , allowing soil to dry out slimly between sessions .

A simple trick I be intimate is to essay the soil wet by sticking a digit two inch into the ground — if it feel dry at that profoundness , it ’s time to water ; if it ’s still damp , give it another day . During our scorching summertime hebdomad , I switch to other - sunup watering to reduce drying up and insure pollinators like bees can scrounge in cool hours without being startled by a sudden shower . Remember , aboriginal plant — like imperial coneflower ( Echinacea purpurea ) from the primal U.S. prairies — often thrive with less frequent lacrimation due to their drought - tolerant genetics , whereas exotics may need more uniform moisture . infer each flora ’s origin and water needs will save you from constant yo - yoing between soggy and parch .

Planting Seeds or Seedlings Too Densely

It ’s oh - so - enticing to bone up every square inch with seedlings because you ’re eager for a lush , full garden . But overcrowd reduces airflow , creating a intimate , humid surroundings where powdery mildew and other fungous diseases sleep with to nest . Plus , plants fighting for root space and nutrients tend to become long-legged and weak , making them promiscuous object for pests like cabbage loopers on your broccoli or tomato hornworms on your heirloom tomato plant .

One of my best-loved coming is using the “ thinning ” method acting : sow slenderly more seeds than you want , then gently slight to the advocate spacing once seedlings get their first true leave of absence . For instance , lettuce seedlings , native to the Mediterranean but raise widely , should be space at least six to eight in apart to prevent damping - off disease and to see each plant receives ample food . confide me , giving seedling elbow room to stretch out their roots and bask in sun will pay off in a robust , high - give crop — and you ’ll forfend the frustration of replanting fall vegetables because your spring greens did n’t make it !

Ignoring Companion Planting and Benefits of Diversity

It breaks my gardener ’s heart when I see a individual - species monocrop , like a sea of zucchini with no companion in tidy sum . Companion planting — such as interspersing marigolds to attract good hoverflies and guard off nematode worm — boosts biodiversity and Stephen Foster a balanced ecosystem . aboriginal flowering plants like goldenrod ( Solidago spp . ) or bee balm ( Monarda fistulosa ) can draw in pollinator and predatory insects that nest nearby and feast on pest that feed on your veggies .

I sleep together how overwhelming it can finger to learn about every possible pairing — tomatoes love basil , dill draw in calamitous swallow-tailed coat butterflies , and onion plant can dissuade Daucus carota sativa flies ! But even plant a few strategic flowers or herbs between rows of kale or bean plant can have major benefits . Those bees draw close in mint clusters wo n’t just pollenate your cuke ; they ’ll also keep predator populations in check . So refuse the impulse to plant in neat , mono - blocks ; instead , adopt a patchwork of colors and textures that fend for ambrosia - eat insects and soil - build microbes . Your garden will hum with life , and you ’ll promptly smell the concord rather than wrestle with constant gadfly pressing .

Overapplying Synthetic Fertilizers and Pesticides

I get it — everyone wants vainglorious , blue tomato fast ! But slathering on synthetical fertiliser and chemic pesticide might give an initial increase spurt , only to backlash when you realize beneficial dirt ball — like ladybird nesting under your marigold leaves — have fell . Overfertilization can lead to undue foliar ontogenesis , attract aphid in droves and creating lush canopies where slugs and snails hide . Meanwhile , chemical substance pesticides often wipe out pollinator and predatory wasp that naturally keep cat in check .

adjudicate a gentle , more sustainable approach : build healthy grunge with constitutive matter and compost to feed plants bit by bit , fostering potent root systems that fend blighter and diseases . If you postulate to deter something specific , like Nipponese mallet that favour rose hips of non - aboriginal sort , consider handpicking or using targeted , organic treatment like neem oil color — never mantle - spray broad - spectrum insecticides . I sleep with splosh natural compost tea leaf around my cucumbers — it ’s like a power - up for microbes , and chatterbox snuggle in my apple tree get busy eating caterpillars , helping me avoid abrasive chemicals altogether .

Neglecting to Prune at the Right Time

I acknowledge how tempting it is to prune whenever you have five extra second — but time matter ! shorten back yield Tree or berry bush at the wrong time can induce young growth just as cold snaps get in , leaving supply ship shoots susceptible to frost impairment . For instance , pruning peach Tree in previous descent can remove the protective level of older wood that helps them survive wintertime ; rather , master gardener recommend waiting until late winter or other leap , when Tree are still sleeping but you’re able to see the issue buds .

Proper pruning also influences how plants pull wildlife . A leafy rise bush left unpruned may host beneficial insects , but without airflow , calamitous place fungus curing in , harming overall wellness . In contrast , a well - timed spring pruning of your aboriginal elderberry ( Sambucus canadensis ) invite songster to nest in its thicker offshoot later in summer , while also preventing overcrowding that would otherwise invite fungous nesting . Careful pruning — with implicit in noesis of each species ’ native growth cycle — yields goodish plant and more ask over home ground for pollinator and nesting fauna alike .

Failing to Rotate Crops Seasonally

Planting tomatoes in the precise same point year after twelvemonth feel commodious , but that ’s a surefire way to build up grunge - borne disease and pest populations , like ascendant - slub roundworm that favour solanaceous crops . harvest rotation is n’t just about move plants around — it ’s about realise syndicate pigeonholing . For case , peppers , love apple , and potatoes all go to the nightshade family ( Solanaceae ) and share pests and disease , so throw to leguminous plant or Brassica in that bed next season help break pest cycles/second .

When I explicate this , new gardeners often say , “ But I only have a little speckle ! ” Even a modest garden can benefit : after a pepper harvest , intersperse native legume like lupin ( Lupinus perennis ) , which cook nitrogen in the soil and provide foraging habitat for native bee . Next year , swap in your peppers where the lupine bloom , and follow how the enriched land — along with fewer nematodes nesting unseen beneath — boosts yields . Rotating like this keeps your plants strong and cuts down on those desperate mid - time of year battles with wilts or pests .

Neglecting Weed Control Until It’s Overwhelming

You might mean , “ I ’ll pull those grass subsequently when I have more time , ” but ungoverned dope can launch an all - out state of war against your vegetable . Take a native North American wild flower like black - eyed Susan — without your bill , it might sow prolifically and push out less aggressive natives or sister gelt . Meanwhile , trespassing pot like oxeye daisy or Canada thistle can monopolize weewee and nutrients , leaving your prized garden corn stunted and fight to bring about ears .

It ’s such a bummer when you render from holiday to find your raised beds overrun ! Master gardeners recommend staying on top of weed by mulching around seedling with chaff or sliced bark — this blocks sunshine and prevents seeded player germination . If you catch that creeping perennial like quackgrass while it ’s young , you ’ll save yourself hours of thwarting later . Plus , consistent weeding help you notice former signs of plague nuzzle at the root word of plants — mayhap folio miner damage on Spinacia oleracea saplings — so you’re able to intervene before the infestation goes from bad to catastrophic .

Overlooking Native Pollinator Habitats

There ’s nothing quite like watching a hummingbird brood around cardinal flower ( Lobelia cardinalis ) or a humblebee nuzzle in a patch of goldenrod — those moments remind me why horticulture is so much more than growing food . Yet many new gardeners center solely on veggie or ornamental cultivar , ignore the fact that aboriginal pollinators need specific plants to thrive . Without a multifariousness of native bloom — like purple coneflower ( Echinacea purpurea ) or milkweed ( Asclepias syriaca)—your garden wo n’t appeal and sustain the full spectrum of bee , butterfly , and hummingbirds .

I recall an aim nurseryman tell me , “ I want vegetables , not flower ! ” But once she inclose a patch of native prairie species , everything change — bees nest in hollow stem of goldenrod proliferated , and tomato plant crop pollination soared . Integrate at least a 12 aboriginal wildflowers or shrubs that bloom at staggered times , put up nesting bumblebees in early spring and swallowtail butterfly in late summer . This proportionate blend not only beautifies your blank space but ensures robust yield correct and healthy garden dynamics .

Forgetting to Compost and Build Soil Organically

I ca n’t stress enough how frustrating it sense to rely only on bag nutrients when your soil still feels like brick — root word struggle to penetrate , and even hardy natives like Achillea millefolium ( Achillea millefolium ) ca n’t establish inviolable footholds . Composting kitchen scraps , yard waste material , and fallen leaves build porous , crumbly dirt teeming with good microbes . These microorganisms break down organic matter , release nutrients gradually , and help plants like daylilies ( Hemerocallis fulva ) and aboriginal aster ground unwaveringly .

When you neglect composting and rely solely on store - buy amendments , you overleap out on forming that rich , living grease that retains moisture , buffer pH swings , and supports a thriving worm population . worm do so much more than you ’d think — by tunneling and conflate compost into deeper dirt layer , they produce channels for moisture and atomic number 8 , enhance root growth . Trust me , once you start layering compost under your spring transplant — whether it ’s attic , squash , or a patch of native maidenhair fern ( Adiantum pedatum)—you’ll curiosity how you ever garden without that soil - binding , nutrient - rich “ fateful gold . ”
