Spring houseplant care
What to do in spring – how to prep your plants for healthy summer growth
We’re feeling that spring feeling! The days are longer, we’re using less heating (great for your houseplants), and dormant plants are starting to put out fresh growth again. If your houseplants have been sitting fairly still through winter, this is the point where a bit of attention now can make a real difference by summer.
Good spring houseplant care is less about doing everything at once and more about making a few thoughtful adjustments. A check on light, watering, feeding and pot size is often enough to set your plants up for a stronger growing season ahead.
Why spring houseplant care matters
For many houseplants, spring is the start of active growth. As daylight increases and temperatures become a little more stable, plants are generally better able to put energy into new leaves, roots and stems. That is why spring is usually the best time to repot, restart feeding and make small care changes that help carry them through summer.
In London homes, that seasonal shift can be quite noticeable. A bright sill can suddenly become a strong growing spot by May. Equally, a plant that was happy tucked back from the window in winter might now need a little more space, a turn towards the light, or slightly more regular watering.
Check which plants are back in active growth
Before you start repotting or feeding everything in sight, it helps to look closely at what each plant is actually doing.
Signs your plant is waking up for the season
A houseplant moving into active growth will often give you a few clear signs – fresh leaves are beginning to grow and unfurl, you’ll spot new stems or shoots at the base, soil will start drying out a little faster than it did in winter, you might spot leaves turning more noticeably towards the light and growth will appear more steady.
This first check matters because not every plant moves at the same pace. Your pothos or philodendron for example, may already be pushing out new growth, while a ZZ plant or snake plant might still be taking its time. Successful spring care works best when you follow the plant rather than the season alone.
When to repot houseplants in the UK
One of the most common spring questions is when to repot houseplants in the UK. In most cases, spring is the right time, because plants are entering a period of active growth and are better able to settle into fresh compost and a slightly larger pot. You can read our in-depth repotting guide here which gives you practical step-by-step instructions on how to successfully repot your houseplants
It’s worth noting that you don’t always need to repot all of your plants every year. Many houseplants only need moving on every two to three years, especially if they are slow growers or you are happy with their current size.
Signs a plant needs repotting
A plant may be ready for a new pot if you notice roots coming through the drainage holes, water is running straight through without soaking in properly, soil dries out much faster, growth feels slower than anticipated even entering the spring and summer months.
When to feed houseplants in spring
As growth restarts, plants need more support than they do during the darker months so spring is the time to begin feeding them.
As a general rule of thumb, feed your houseplants with fertiliser once or twice a month from March to October. For cacti and succulents, a monthly feed from April to September is generally enough.
How often to feed different types of houseplants
Here is a simple guide:
Leafy tropical houseplants
Plants such as monstera, philodendron, pothos, calathea and peace lily usually benefit from regular feeding through spring and summer. Once or twice a month is often enough.
Cacti and succulents
These tend to need less. A monthly feed during the warmer growing period is usually plenty.
Newly repotted plants
If you have just repotted, hold off feeding straight away. Fresh soil often gives the plant enough to work with for the first few weeks, and adding feed too soon can flood them with too many nutrients.
If you are wondering when to feed houseplants in spring, the safest answer is when you can see they are actively growing. Start gently, then build into a regular routine as the season settles in.
Adjust your watering routine before summer arrives
Watering is usually the thing that needs the quickest reset in spring. As the days get longer and rooms warm up, many plants start using water more quickly. The simplest approach is to check the soil more often. Dip a finger into the soil, lift the pot to judge its weight, and pay attention to how quickly it is drying between waterings.
This is especially true in London period properties and modern builds, where conditions can vary a lot from room to room. A sunny front bay, a cooler bedroom and a bathroom with good humidity may all behave completely differently. If you want to encourage houseplant growth, steady watering matters more than dramatic watering. Long dry spells followed by a heavy drench can be harder on the plant than a more even routine.
Move plants into better light and rotate them
Spring is a good time to reassess where your plants actually live.
A plant that tolerated a lower-light corner in winter may be much happier closer to the window now. At the same time, stronger late spring and summer sun can catch out softer-leaved plants, especially if they have spent months in cooler, low-light conditions.
So instead of a sudden move into full sun, make gradual changes. Bring plants a little nearer to the light, keep an eye on any bleaching or scorch, and use a sheer curtain if the midday sun feels too harsh. Rotation helps too. Turning plants every week or two encourages more even growth and stops them leaning too heavily in one direction. It is a small tweak, but it can make a big difference by midsummer, especially for trailing plants or anything sitting on a windowsill.
Clean, prune and support fresh growth
A spring reset is also a good chance to deal with the little jobs that are easy to ignore through winter, starting with the leaf cleaning. Dust blocks light and makes it harder to spot early pest issues, so wipe broad leaves gently with a damp cloth. For smaller or more delicate foliage, a soft brush can work well.
Then look at the overall shape of the plant. Remove anything yellowing or damaged, and if stems have become leggy over winter, a light trim can help the plant redirect energy into healthier new growth.
For climbing plants, this is also a useful moment to add support. A moss pole, cane or hoop can help guide the shape before the summer growing spurt really begins. Training growth early is usually easier than trying to tidy a plant once it has already started to move in every direction.
Finally, check for pests. Spring is often when issues like spider mites, fungus gnats or mealybugs become more noticeable so catching them early is always easier than trying to fix a bigger problem later.
A simple spring houseplant care routine to carry into summer
Check which ones are actively growing, repot only the plants that need it, begin feeding again, adjust watering as the light changes, and make sure each plant is sitting in the best spot for its needs. Small changes now can lead to steadier growth, healthier leaves and plants that feel much more settled by the time summer arrives.
