Plant Growing Guides
Straightforward care guides for popular garden plants and houseplants — light, water, soil, pruning, and the problems that come up most. Every guide is free to read here, with a printable PDF version available if you'd rather keep it with your garden notes.
Rhododendrons
Rhododendron spp.
Most rhododendron problems trace back to one thing: planting too deep in soil that isn't acidic enough. Fix that and the rest is easy.
Marigolds
Tagetes spp.
Marigolds are about as forgiving as garden flowers get — full sun, average soil, and regular deadheading is nearly the whole system.
Geraniums
Pelargonium spp.
The garden geranium most people plant in pots isn't a true hardy geranium at all — it's a Pelargonium, and it can be overwintered indoors for years of reuse.
Begonias
Begonia spp.
The right care for a begonia depends heavily on which type you have — wax, tuberous, or rex — and mixing up their needs is the most common way to lose one.
Irises
Iris spp. (bearded iris)
The single most common iris mistake is planting the rhizome too deep — it should be visible at the soil surface, not buried like a bulb.
Chrysanthemums
Chrysanthemum spp.
Most fall-pot mums are sold and treated as annuals — but garden (hardy) mums planted early enough in the season can genuinely come back as perennials.
Privet
Ligustrum spp.
Privet's biggest advantage as a hedge — fast, dense growth — is also its biggest maintenance demand. Skipping a summer trim shows immediately.
Olive Trees
Olea europaea
An olive tree can't survive a Canadian winter outdoors, but grown in a container and moved seasonally, it's a genuinely manageable long-term plant.
Lilies
Lilium spp.
True lilies are one of the more reliable bulbs a Canadian gardener can plant — the main threats are the red lily beetle and cutting the stem too short after bloom.
Wandering Jew (Inch Plant)
Tradescantia zebrina
Wandering jew is one of the easiest houseplants to propagate — a single cutting in water will root in days, which is exactly how most collections started.
Boxwood
Buxus spp.
Boxwood's winter bronzing (leaves turning orange-brown) alarms a lot of gardeners every spring — most of the time it's cosmetic, not a sign the plant is dying.
Daylilies
Hemerocallis spp.
Daylilies are about as close as perennials get to 'plant and forget' — the only real maintenance decision is when to divide an overcrowded clump.
Beans
Phaseolus vulgaris
Bush beans give you one big harvest window; pole beans give you weeks of picking from the same square foot — plant both if you have room.
Anthurium
Anthurium andraeanum
An anthurium that isn't blooming almost always needs more light, not more fertilizer — it's the single most common care mistake.
Dieffenbachia (Dumb Cane)
Dieffenbachia seguine
Dieffenbachia's sap is toxic enough to cause the throat swelling that gave it the name 'dumb cane' — keep it well out of reach of pets and small children.
Turnips
Brassica rapa
Turnips left unthinned grow all leaf and no root — thinning to 3–4 inches apart is the one step most gardeners skip and regret.
Crepe Myrtle
Lagerstroemia indica
Crepe myrtle is only reliably hardy to zone 7 in Canada — most gardeners here need to grow it in a container and overwinter it indoors, not plant it in the ground.
Sweet Potatoes
Ipomoea batatas
Skipping the curing step is the single biggest reason homegrown sweet potatoes taste bland — curing converts starches to sugars and can double storage life.
Fig Trees
Ficus carica
Most Canadian gardeners kill their fig tree the first winter by leaving it outside — the fix is a container and a cold, dark, dormant spot indoors, not a heated room.
Lemon Trees
Citrus limon
A lemon tree dropping leaves indoors is usually reacting to a sudden change — a cold draft, a big move, or inconsistent watering — not a fatal problem.
Maranta (Prayer Plant)
Maranta leuconeura
Maranta leuconeura is the true prayer plant — its leaves fold up at night like hands in prayer, which is exactly the movement to watch for as a sign of plant health.
Hostas
Hosta spp.
Hostas are about as low-maintenance as shade perennials get, but slugs and deer treat the leaves like a buffet, and that's the part most new gardeners underestimate.
Hoya (Wax Plant)
Hoya carnosa
Hoyas bloom on their own schedule and often refuse to flower at all until they're slightly pot-bound and left completely alone once buds appear.
Peperomia
Peperomia spp.
Peperomia's thick, water-storing leaves make it one of the easiest houseplants to kill with kindness — most problems trace back to watering on a schedule instead of checking the soil.
Bougainvillea
Bougainvillea spp.
Bougainvillea blooms best when it's mildly stressed — overwatering or overfeeding a plant to keep it lush is the single biggest reason Canadian gardeners get leaves and no flowers.
Money Tree
Pachira aquatica
The braided trunk on a money tree is made of several young stems woven together while flexible — it's a nursery technique, not a natural growth habit, and it's permanent once the trunks mature and stiffen.
Petunias
Petunia spp.
Petunias are heavy feeders that bloom themselves ragged by midsummer — a hard cutback in July, not just deadheading, is usually what it takes to get a full second flush.
Avocado Trees
Persea americana
An avocado tree grown from a grocery-store pit can live for years as a healthy houseplant, but it's grown from seed rather than grafted, and seed-grown trees almost never fruit.
Azaleas
Rhododendron spp. (azalea group)
Azaleas are technically a group within the Rhododendron genus and share its acid-soil requirements exactly, but they bloom earlier, prune differently, and are generally smaller than most true rhododendrons.
Black-Eyed Susans
Rudbeckia hirta
Black-eyed Susans are short-lived as individual plants but persist for years through aggressive self-seeding, so the real skill is managing where they spread rather than keeping any one plant alive.
Calathea
Calathea spp. (syn. Goeppertia)
Calathea doesn't die quietly — curling, browning, and drooping leaves are the plant telling you exactly what's wrong, if you know how to read them.
Daffodils
Narcissus spp.
Daffodils are planted once and rewarded for years — the only way to ruin them is impatience with the foliage after they bloom.
Peonies
Paeonia spp.
Plant a peony's crown even an inch too deep and you can get a decade of healthy foliage and zero flowers — depth is the one detail that matters most.
Radishes
Raphanus sativus
Radishes go from seed to harvest in under a month, which makes them the fastest way to find out whether your garden's cool-season timing is right.
Hydrangeas
Hydrangea spp.
More hydrangeas lose their blooms to a badly timed pruning cut than to any pest, disease, or Canadian winter combined.
Artichokes
Cynara cardunculus var. scolymus
Artichokes are perennials pretending to be annuals in most of Canada — the trick to getting a harvest in one season is tricking the plant into thinking it's already lived through a winter.
Onions
Allium cepa
Onions bulb up based on daylength, not the calendar, which means growing the wrong variety for your latitude is the most common reason for small, disappointing bulbs.
Parlor Palm
Chamaedorea elegans
Parlor palm's biggest risk isn't neglect, it's kindness — more of these plants are killed by well-meaning overwatering than by anything else.
Pumpkins
Cucurbita pepo / Cucurbita maxima
A pumpkin vine can sprawl 10 to 15 feet in one summer, so the most common beginner mistake isn't a pest or a disease — it's simply running out of room.
Sunflower
Helianthus annuus
Sunflowers only track the sun while they're young buds — once the flower opens fully, it locks facing east and stops moving, which surprises a lot of first-time growers.
Zinnia
Zinnia elegans
Most powdery mildew problems on zinnias trace back to one thing — plants spaced too close together — and no amount of fungicide fixes crowding.
Air Plant
Tillandsia spp.
An air plant's single bloom is actually the end of that rosette's life — the flowering event triggers the plant to start producing offsets, or "pups," that carry on in its place.
Arborvitae
Thuja spp.
Deer damage and winter bronzing get blamed on each other constantly, but they look different up close — bronzing fades leaf colour evenly, while deer strip whole branches bare, usually up to about 6 feet.
Ornamental Cherry Tree
Prunus serrulata and related spp.
Ornamental cherries are pruned far less than most people assume — heavy cuts invite the fungal disease black knot in through fresh wounds, so the best pruning plan is often the smallest one.
Dahlia
Dahlia spp.
In most of Canada, dahlia tubers won't survive winter in the ground — digging them up before the first hard frost isn't optional the way it is in milder climates.
Coneflower
Echinacea purpurea
Deadheading coneflower all season actually costs you something — the seed heads left standing over winter feed finches and other birds and add structure to an otherwise bare garden.
Dogwood
Cornus spp.
Red-twig dogwood's brilliant winter colour comes almost entirely from young stems — the brightest red or yellow wood is one to two years old, which is why hard, regular pruning actually improves the winter display instead of hurting it.
Holly
Ilex spp.
A holly with no berries almost always comes down to one simple, overlooked detail — hollies are dioecious, meaning most need a separate male plant nearby just to pollinate the female's flowers.
Juniper
Juniperus spp.
Juniper's biggest threat isn't the cold — it's a well-meaning gardener with a hose, since more junipers die from overwatering and poor drainage than from a Canadian winter.
Prayer Plant
Maranta leuconeura
Prayer plant gets its name because the leaves visibly fold upright at night and flatten again by morning — a real, watchable process called nyctinasty, not a sign of stress.
Snake Plant
Dracaena trifasciata
Snake plant survives almost anything except a generous waterer — overwatering is responsible for the vast majority of snake plant deaths, far more than low light, cold, or neglect combined.
Croton
Codiaeum variegatum
Croton's fiery leaf colour is entirely light-dependent — the exact same plant will look muted green in a dim corner and vivid red-orange-yellow in bright light within a few weeks.
Cucumbers
Cucumis sativus
Bitter cucumbers aren't a variety problem — they're almost always a watering problem, since inconsistent soil moisture is the single biggest cause of bitter fruit.
Dracaena
Dracaena spp.
Those brown, crispy dracaena leaf tips almost everyone deals with eventually usually aren't a watering mistake at all — they're a reaction to the fluoride and chlorine in ordinary tap water.
Jade Plant
Crassula ovata
A single dropped jade leaf left on top of the soil will often root and grow into a new plant on its own — this succulent is genuinely that easy to propagate.
English Ivy
Hedera helix
The same trait that makes English ivy such a reliable, fast-filling groundcover outdoors is exactly why parts of Canada, including British Columbia, list it as invasive and restrict its sale.
Lucky Bamboo
Dracaena sanderiana
Lucky bamboo isn't bamboo at all — it's a Dracaena, which explains why it shares that genus's one real weakness: it reacts badly to the chlorine and fluoride in ordinary tap water.
Chinese Evergreen
Aglaonema spp.
Chinese evergreen tolerates lower light than almost any other houseplant, but the colourful cultivars need noticeably more light than the plain green ones to keep their pattern.
Philodendron
Philodendron spp.
Most philodendron problems come from overwatering, not underwatering — the genus is built to dry out between waterings, and soggy soil is the fastest way to lose one.
Camellias
Camellia japonica
Camellia bud drop is almost never disease — it's nearly always a sudden temperature swing or the plant carrying more buds than it can actually open.
Rubber Plant
Ficus elastica
A rubber plant dropping leaves is almost always reacting to a change — a move, a cold draft, or a watering swing — not a sign it's dying.
African Violets
Saintpaulia (Streptocarpus sect. Saintpaulia)
Water touching an African violet's leaves or crown, not the amount of water, is the single most common way people accidentally kill this plant.
Blueberries
Vaccinium corymbosum / V. angustifolium
Poor blueberry fruiting is very often a soil pH problem, not a pollination one — most garden soil simply isn't acidic enough for blueberries to take up nutrients properly.
Apple Trees
Malus domestica
A lone apple tree with no fruit almost always needs a second variety nearby — most apple trees can't pollinate themselves no matter how healthy they look.
Jasmine
Jasminum polyanthum
A jasmine that won't bloom almost always missed its cool winter rest — this vine needs a genuine cold spell to set flower buds, not just bright light.
Impatiens
Impatiens walleriana
Downy mildew has made classic bedding impatiens a genuine gamble in much of Canada in recent years — New Guinea impatiens is the disease-resistant alternative worth knowing about.
Bird of Paradise
Strelitzia reginae
Split leaves on a bird of paradise are usually not a problem to fix — it's a natural adaptation that lets wind pass through the leaf without tearing it.
Succulents
Various genera
Overwatering, not underwatering, kills far more succulents — the soak-and-dry-out cycle matters more than any fixed watering schedule.
