How to Make Succulents Grow Bigger — 10 Tricks That Work
Most hobby succulents stay small because they're kept too dark, too dry, and too hungry — not because they're slow. Here are the 10 things that actually drive size in a Canadian home, and the one trade-off nobody mentions.
Short version: To make succulents grow bigger and faster, give them strong light (south window, summer sun, or a grow light), pot up one size when root-bound, water by soak-and-dry (not chronic neglect), feed dilute fertilizer monthly in the growing season, keep them warm (20–28°C), and remove flower stalks. Pick a fast-growing species like echeveria, sedum or jade. The catch: these same conditions keep a succulent green — stress-colouring red slows growth, so you choose size or colour.
Making succulents grow bigger isn't a secret technique — it's giving a desert plant a genuinely good life instead of the bare-minimum survival most houseplant succulents get. The popular advice ("succulents need almost no light and almost no water") keeps them alive but tiny and static for years. Flip every one of those inputs and the same plant fills out, gains height or spread, and looks like the lush specimens you see online. Here's exactly how, tuned for a Canadian climate, plus an honest look at the size-versus-colour trade-off.
Why Most Succulents Stay Small
A succulent grows when three things line up: enough light to photosynthesise hard, enough water and nutrients to build new tissue, and warmth in its active growing season. Take any one away and growth stalls. In a typical Canadian home, all three are usually short — a plant set back from a north or east window, watered a thimble at a time "because succulents are drought plants", never fed, and parked on a cold winter sill. It survives on stored water and minimal light, but it has no surplus to grow with.
The fix is to stop treating "drought-tolerant" as "wants drought". Succulents tolerate hard conditions; they grow in good ones. The 10 tricks below are simply the good conditions, in order of impact.
The 10 Tricks, in Order of Impact
☀️ 1. Maximise light — the master switch
Light is the single biggest driver of size. Strong light produces fat, compact, healthy growth; weak light produces thin, stretched, slow growth (etiolation), where the plant spends its energy reaching for a window instead of bulking up. Give the brightest spot you have — an unobstructed south or west window, outdoor summer sun (acclimated slowly), or a full-spectrum grow light. Everything else on this list only works if light is sufficient.
💧 2. Water properly — soak and dry
Chronic underwatering is the number-one reason hobby succulents stay tiny. During the growing season, drench the soil until water runs out the drainage hole, then wait until it's completely dry before watering again — usually every 1–2 weeks indoors. This "soak and dry" rhythm fuels real growth. A few drops every few days, by contrast, keeps the plant permanently thirsty and small. (This is the opposite of the deliberate drought used for colour.)
🧹 3. Pot up one size when root-bound
A succulent whose roots have filled its pot slows down. When you see roots circling the bottom or poking out the drainage hole, move it to a pot just 2–3 cm wider. Don't over-pot — a pot that's too big holds water long after watering and rots the roots. Pot up one size at a time, only when needed, always into a container with a drainage hole.
⛏ 4. Use gritty, fast-draining soil
Healthy roots build a healthy top. Plant in a mix that's roughly half mineral grit — pumice, perlite, or coarse sand — cut into regular potting soil. Dense, water-retentive soil suffocates succulent roots and stalls growth (or rots them outright). Good drainage lets you water generously without rot, which is what makes the soak-and-dry rhythm safe. See our succulent potting mix recipe →
🍽️ 5. Feed during the growing season
Unfed succulents grow slowly. Feed a dilute balanced fertilizer at quarter-to-half strength once a month during active growth (spring through early autumn for most), and stop entirely in dormancy and over winter. Don't overdo it — too much fertilizer pushes soft, weak, stretched growth and can burn roots. A little, regularly, in season, is the sweet spot.
🌡️ 6. Keep them warm
Most succulents grow fastest at 20–28°C daytime warmth. A cold Canadian windowsill in winter — where night air against the glass can sit near freezing — nearly halts growth. Keep growing plants in a warm room, off cold glass, and they'll keep building tissue. (Cool nights are great for colour, but they slow size.)
📅 7. Work with the growing season (and dormancy)
Push hardest when each plant is actually growing. Summer growers (Echeveria, Sedum, Crassula, Kalanchoe) build size spring through autumn and rest in winter; winter growers (Aeonium, Haworthia, Gasteria) grow in the cooler months and pause in summer heat. Concentrate your watering and feeding in each plant's active season, and ease right off in its dormancy — feeding a dormant succulent just rots it.
✂️ 8. Remove flower stalks (and offsets, if you want one big plant)
Flowering drains a lot of energy, and a few succulents (many Aeonium, some Sempervivum and Agave) are monocarpic — the rosette dies after it blooms. If size is the goal, snip flower stalks off early to redirect that energy into growth. For rosette types that produce pups, removing the offsets channels the plant's energy into the main rosette so it grows larger, rather than into a clump of small ones.
💡 9. Add a grow light for the Canadian winter
From November to February, Canadian window light is too weak to grow most succulents — they simply pause for four to five months, which is a lot of lost time. A full-spectrum LED on a 10–12 hour timer, 20–30 cm above the plants, keeps summer growers building size right through winter. It also prevents the pale winter stretching that ruins a compact shape.
⏳ 10. Start with a fast grower — and skip the stress
Genetics set the ceiling on speed. If you want size sooner, choose a fast-growing species (echeveria, sedum, jade, aeonium, kalanchoe) rather than a slow one (haworthia, gasteria, lithops, most cacti). And accept the trade-off: the sun-and-drought stress that turns succulents vivid red also slows their growth. You can grow a big green succulent or a small colourful one — rarely both at once. Here's the colour side of that trade-off →
Fast vs Slow Growers — and When They Grow
| Succulent | Growth speed | Active growing season |
|---|---|---|
| Jade (Crassula ovata) | Fast | Spring–autumn (summer grower) |
| Echeveria | Fast | Spring–autumn |
| Sedum (incl. 'Burrito') | Fast | Spring–autumn |
| Kalanchoe | Fast | Spring–autumn |
| Aeonium | Fast | Autumn–spring (winter grower) |
| Sempervivum (hens-and-chicks) | Moderate | Spring–summer (hardy outdoors) |
| Haworthia, Gasteria | Slow | Cooler months; rest in summer heat |
| Lithops, most cacti | Very slow | Species-dependent; genetically slow |
Mistakes That Keep Succulents Small
- Watering a thimbleful "because succulents barely need water". The biggest one. Soak and dry instead.
- Too little light. A succulent in a dim corner stretches and thins rather than bulking up — it isn't growing, it's reaching.
- Never potting up. A permanently root-bound plant is a permanently small plant.
- Never feeding. No nutrients, no new tissue. Dilute feed in the growing season fixes it.
- Stress-colouring full-time. Keeping a plant in constant sun-and-drought for the red look means it never gets the surplus to grow.
- Pushing growth in dormancy. Watering and feeding a resting succulent rots it — match effort to the active season.
Frequently Asked Questions
What makes succulents grow the fastest?
Strong light plus the soak-and-dry watering rhythm plus warmth in the growing season. Of the three, light does the most work — a fast-growing species like echeveria or jade in a bright south window, watered thoroughly whenever the soil dries out and fed dilute fertilizer monthly through spring and summer, will gain noticeable size in a single season. Add a grow light to extend that through the Canadian winter.
My succulent is stretching tall and thin — is that growing?
No — that's etiolation, and it means too little light, not healthy growth. The plant is stretching its stem and spacing its leaves to reach toward a light source. It looks like it's getting bigger but it's actually getting weaker. Move it to much brighter light or add a grow light. The stretched part won't shrink back, but you can behead the rosette, let it callus, and re-root it as a compact plant — and the bare stump usually sprouts new offsets.
Can I make a succulent grow taller, or just wider?
It depends on the plant's natural form. Rosette types (echeveria, sempervivum) mostly grow wider and form a thicker, fuller rosette rather than gaining height. Shrubby and tree-form succulents (jade, aeonium, some kalanchoe) genuinely grow taller and can be trained into a small trunk over years by removing the lowest leaves as the stem thickens. Trailing types (string of pearls, burro's tail) grow longer. Good care makes each one bigger in its own natural direction — it won't change a rosette into a tree.
How often should I water to grow bigger succulents in Canada?
By feel, not by calendar — water thoroughly whenever the soil has gone completely dry, which indoors is usually every 1–2 weeks in the warm growing season and far less in winter. The key is the rhythm: a full soak, then full dry-out, then repeat. In gritty fast-draining soil this is safe and drives growth; in dense soil it rots roots, which is why the right mix matters before you increase watering.
Why can't I have big and brightly coloured succulents at the same time?
Because the two depend on opposite conditions. Size needs comfort — generous water, feeding, warmth — so the plant has surplus energy to build tissue. Vivid red and purple colour needs stress — intense sun, cool nights, and drought — which the plant survives by diverting energy into protective pigments instead of growth. Many growers run a cycle: feed and water for size most of the year, then apply controlled stress for a few weeks to colour up before showing the plant off. Full stress-colouring guide →
