Spring houseplant care — the complete guide

Spring is the season when houseplant care flips. All winter the advice was do less — water sparingly, stop feeding, leave resting plants alone. As the days lengthen and strengthen, that same restraint starts holding plants back. Growth returns, thirst returns, appetite returns, and the routine that kept a plant safe in January will now leave it hungry, pot-bound and stretching for light. The good news is that spring care is mostly about restarting things you paused — gently, and in the right order. This guide is the counterpart to our complete guide to houseplant winter care: it ties the whole spring cluster together, summarising each shift and linking to the dedicated deep-dive for anything you want to explore in depth.

Set up Growli for the season: Add your plants to Growli and it recalculates each watering reminder as the light returns — so you're prompted more often through spring, tuned to your window, your room, and the plant in front of you.

What actually changes in spring

Four things shift at once, and every spring care rule flows from them:

• More light. Days lengthen and the sun climbs higher and stronger, so a room delivers far more light energy than it did in midwinter — sometimes enough to scorch a plant that was happy on the same sill in December.
• Warmer, longer days. Rising temperatures and daylight signal most tropical foliage plants to break their winter rest and start producing new leaves.
• Active growth. As they wake, plants drink more, use nutrients again, and fill out their pots with fresh roots — which is exactly why spring is repotting season.
• Pests wake too. The same warmth that revives your plants revives any overwintering sap-suckers, so spring is when small infestations can suddenly take off.

Here is the whole spring playbook in one table. The rest of the guide unpacks each row.

Ramp watering back up — but still check the soil

The single biggest winter adjustment was watering less. In spring you reverse it: as light and warmth return, plants grow faster and drink more, so soil that took two weeks to dry in January may be dry in a matter of days. A plant left on its winter schedule now risks going thirsty, wilting or dropping leaves.

The rule that keeps you safe stays exactly the same — water by the soil, not the calendar — you just check more often. Push a finger in; if the top inch (about 2–3 cm) is dry, water thoroughly until it runs from the drainage holes, then tip away anything that collects in a saucer or cover pot so the roots never stand in water. The change in spring is frequency, not method: expect to move from every week or two back toward a summer rhythm as the season builds. Watch for the plant telling you it's thirsty — soil pulling away from the pot's edge, a pot that feels suddenly light, or the first faint wilt after a warm, bright week.

Resume feeding — gently, once growth returns

Fertiliser feeds growth, and spring is when growth restarts — so this is when feeding restarts too. The mistake is going in too hard, too early: a plant that has only just woken can't use a full-strength dose, and the excess builds up as salts that scorch roots. Wait until you actually see new growth — a fresh leaf, a lengthening stem — then start light and diluted.

A sensible restart is a balanced houseplant feed at about half strength, every two to four weeks through the growing season, building up as growth accelerates into summer. The RHS growing guide suggests feeding once or twice a month, or a quarter-strength dose at every watering, across the March-to-October growing season. Only ever feed moist soil, never a bone-dry rootball. For where the line sits for your plants — including which types want more and how our winter guide's "stop feeding" advice hands over to spring — see should you feed houseplants in winter?, which covers the full stop-and-restart cycle.

Repot if it needs it — spring is the window

Spring is the ideal time to repot, because the plant has a full growing season of light and warmth ahead to recover and put out fresh roots. That's the opposite of winter, when disturbing a resting plant sets it back. But "ideal time" doesn't mean every plant needs it every spring — repot only the ones that have genuinely outgrown their pot.

The classic signs are roots circling the inside of the pot, roots creeping out of the drainage holes, soil that dries out unusually fast, or a plant that has stopped thriving despite good care. When you do repot, go up just one pot size — too much extra soil holds too much water around roots that can't reach it. We won't re-teach the mechanics here: for how to tell if a plant is truly pot-bound, read how to spot a root-bound plant; for the exact method — easing the plant out, teasing the roots and settling it into fresh mix — follow how to repot a houseplant, step by step; and for the full seasonal decision, see when to repot houseplants — best timing.

Prune and shape as new growth begins

Winter told you to hold off pruning; spring is when it pays off. Cutting back just as a plant resumes active growth means it heals fast and channels its energy into bushy new stems rather than long, leggy winter growth. It's the moment to remove any leaves that yellowed or died back over the dark months, cut leggy stems back to a healthy node to encourage branching, and shape trailing or top-heavy plants before the summer surge.

Light shaping suits almost everything; harder renovation pruning is best matched to the plant, so don't take a lot off a slow grower or a plant that flowers on old growth. For which plants to cut, how far to go, and where to make each cut, see pruning houseplants in spring — when and how, and our broader guide to pruning houseplants for technique that applies year-round.

Increase light gradually — don't scorch a waking plant

Here is the spring trap that catches people out. Over winter you likely moved plants right up to your brightest window to catch what little light there was. As the sun climbs and strengthens, that same sill can go from perfect to scorching, and leaves that acclimatised to weak winter sun can burn in strong spring rays — showing up as pale, bleached or crispy patches on the most exposed leaves.

The fix is to move in stages, not all at once. If a plant needs a brighter spot, shift it a little closer to the window over a week or two rather than in one jump, giving the leaves time to adjust. Delicate, shade-preferring plants — think pothos, philodendrons, calatheas and ferns — are the ones most likely to burn behind glass that's now catching midday sun, so a sheer curtain or a step back into bright, indirect light protects them. The same slow-adjustment principle applies, only more so, if you plan to move plants outdoors for the warmer months.

Wake plants gently — read the plant, not the date

Not every plant wakes on the same day, and pushing a still-resting plant into a full growth routine does more harm than good. The signal to ramp everything up is the plant itself: new leaves unfurling, stems extending, the pot drying faster than it did all winter. Until you see those signs, keep watering and feeding on the lighter end and let the lengthening days do their work.

Waking a houseplant is really just the ordered restart of everything above — more light, then more water, then feeding, then repotting and pruning — done in step with what the plant shows you. For the full week-by-week routine, including how to coax a sluggish plant back into growth and tell waking from struggling, see how to wake houseplants up in spring.

Watch for pests waking up too

The warmth that revives your plants also revives pests. Sap-suckers that sat quietly through winter — fungus gnats, spider mites, aphids, mealybugs, scale — start breeding fast in spring, and a few missed insects in March can become an infestation by May. Spring's fresh, soft new growth is exactly what many of them target.

Make inspection a habit while you water: turn a few leaves over and check the undersides and the joints where leaf meets stem, where pests like to hide. Look for fine webbing, sticky residue, tiny moving specks or cottony white tufts. Catching an outbreak early — wiping it off, rinsing the plant, or treating a single affected specimen away from the others — is far easier than fighting it once it has spread. Browse plant-care guides by species for the pests and quirks specific to the plants you own.

Thinking about moving plants outside?

Many houseplants relish a summer outdoors, but the move needs care and it belongs to later in the season. Wait until nights are reliably warm — as a working rule, until they stay above about 50°F (10°C) — because tender tropicals resent a cold night. Then harden plants off gradually: start them in full shade outside and build up their light exposure over a week or two, because even a "high-light" houseplant will scorch if it goes straight from a windowsill into direct sun.

That's a whole project in itself, so we've given it its own guide. For the timing, the hardening-off schedule, choosing the right outdoor spot, and bringing plants safely back in before autumn, see moving houseplants outside for summer.

Your spring routine, in three steps

1. Today: Check every plant's soil with a finger and water the ones that have dried out — you'll find more of them than you did in winter. Look over each plant's leaves and stems for the first signs of pests.
2. This week: Give plants showing new growth their first light, half-strength feed, and prune away any winter dieback and leggy stems. Ease anything that needs more light a little closer to its window rather than in one jump.
3. This month: Repot the plants that have genuinely outgrown their pots, going just one size up, and settle into checking soil more often as the growing rhythm builds. Keep inspecting for pests as the weather warms.

Common spring mistakes to avoid

1. Still watering on the winter schedule — plants drink far more as they wake, and a leftover winter rhythm leaves them thirsty. Check the soil more often.
2. Feeding too hard, too soon — a plant that has only just woken can't use a full dose, and the excess builds up as root-scorching salts. Start diluted, once you see new growth.
3. Moving a plant into strong sun overnight — leaves acclimatised to weak winter light burn in strong spring rays. Increase light in stages.
4. Repotting for the sake of it — spring is the window, but only for plants that have actually outgrown their pot. Over-potting into a much bigger pot holds too much water.
5. Missing the first pests — a few insects in early spring become an infestation by summer. Inspect while you water.
