Most houseplants profit from repotting yearly or two within the early phases of progress or each three or 4 years for giant and mature crops that simply want new soil.

When To Repot Houseplants
On a macro scale, the very best time to repot your houseplants is barely once they actually need it. We’ve all introduced a brand new houseplant residence and needed to maneuver it to a model new pot instantly, however ready till the precise time when your plant is just not already burdened will assist restrict threat.
The chance concerned is additional stress and transplant shock. Houseplants don’t like having their roots uncovered to the air and dealt with unnaturally. In addition they don’t like modifications in environments, together with issues like new soil situations. Though repotting does enhance progress in the long run, it additionally ends in short-term stress that you just don’t wish to induce usually.
There are indicators you need to look out for to point when it’s time to repot, which we’ll have a look at subsequent. However even in case you don’t discover these indicators directly, you need to nonetheless take into account repotting each 4 years or so in case you haven’t repotted shortly.
On a micro-scale, the very best season to repot is normally spring. Most houseplants begin creating new progress right now, and the hotter temperatures will help in fast restoration after repotting. You may repot each time it’s heat, though you’ll want to look at your watering if repotting when temperatures are excessive.
Whereas it’s not perfect to repot in fall or winter, it received’t do any severe injury in case your indoor temperatures are nonetheless comparatively heat. They’ll take a bit longer to bounce again, so don’t fear in case you don’t spot any improved progress for a number of weeks.
When you’re repotting on account of issues with progress, akin to root rot, don’t wait till the climate warms. Repot instantly, regardless of the season, to take away the injury and stop unfold.
Indicators Your Houseplant Wants Repotting
Repotting on a schedule (akin to one per yr in spring) may also help you keep away from forgetting this important process. Nonetheless, it doesn’t take into account the plant’s actual wants. As a substitute, look out for these basic indicators that your houseplants want a brand new residence.
Roots Rising Via Drainage Holes
The primary signal is without doubt one of the best indicators that your houseplant could also be struggling: roots rising via drainage holes.
Because of the constrained area in containers, the plant’s roots will ultimately hit the sting of the pot. From right here, they are going to begin circling across the container or rising again into the soil. However when there is no such thing as a area left on the backside of the pot, sprawling roots will attain for room by rising via the holes within the backside.
This normally occurs when your houseplant is in a pot cowl or on a drip tray. The roots attain downwards in the direction of the moisture, rising out of the drainage holes. Not solely does this imply the roots are significantly missing area, however this may additionally block the drainage holes, risking waterlogging and decay.
When you elevate the plant out of its container, you’ll doubtless see roots packed on the backside, taking the form of the container. The roots will wrap round one another, struggling to soak up moisture or vitamins. In these circumstances, it’s greatest to repot as quickly as doable, regardless of the season.
Roots Circling The High Soil
Equally, you might discover roots peeking via the topsoil, presumably earlier than they come out the underside of the container. Rising upwards is definitely not a standard follow for roots and tells you they don’t have any extra room on the backside of the container, in search of room on the prime as a substitute.
Circling roots on the prime can even trigger a phenomenon referred to as girdling. In girdling, the plant strangles its personal mainstem by encircling it with roots. Evidently, this isn’t perfect!
This can be brought on by shallow watering; in different phrases, watering solely the highest layer of soil with out saturating it fully. When you solely add small quantities of water at a time, this can be the offender quite than a scarcity of area. Ensure you water totally till moisture runs via the drainage holes to make sure you’re watering sufficiently.
Dry soil is normally an indication that your houseplant is missing water. Noticing the dry soil, you in all probability resolve to water, maybe backside watering, to completely saturate the soil with out moisture operating down the edges. However what occurs if the soil is unusually dry once more just some days later?
This can be a signal of poor soil construction. The soil in containers disintegrates over time, shedding its potential to carry onto moisture and vitamins. This negatively impacts root well being and progress above the soil, resulting in wilting and discoloration.
Underwatering is the primary concern to handle. But when that’s not the problem, it could be time for a soil refresh.
When roots begin wrapping round one another with nowhere else to go, it is smart that you just received’t spot any new leaf or stem progress both. The roots assist progress above the soil, so in the event that they’re caught, the remainder of the plant will likely be too.
Stunted progress is troublesome to diagnose. For one, your plant received’t at all times quickly produce new leaves and stems. Some crops develop slower than others, making stunted progress troublesome to determine.
Lack of progress additionally has many causes – not simply lack of area. Insufficient lighting, sudden modifications in atmosphere, chilly temperatures, or inconsistent watering are among the most typical causes for stunted progress.
Lifting your plant out of its pot is the simplest strategy to inform if it’s constricted. That is tough for bigger houseplants, however it’s the easiest way to look intently on the roots. If they’re crowded and overgrown, repot. If not, search for different potential causes first to keep away from compounding the stress.
Browning and yellowing leaves are one other signal that your plant is struggling. These might be brought on by incorrect situations or care however can even point out when your plant wants extra room or higher soil. Begin by pruning these off, then test the roots to resolve whether or not it’s time to repot or not.
If pests or illnesses are inflicting the discoloration, repotting should be the reply, even when the plant doesn’t want extra space. Many houseplant pests can conceal within the soil, the place they reproduce and unfold to different crops. Circumstances like root rot should even be resolved by repotting to take away the problematic fungus.
Detective work will assist you discover the basis trigger. Like stunted progress, you don’t wish to repot and enhance stress if there’s a completely different trigger.
How To Repot Houseplants
When you’ve decided it’s time to repot, you may observe these simple steps to get it proper. Though it could seem to be a tedious process in comparison with issues like watering, it may be fairly therapeutic. Take into account it a time to bond along with your houseplants and enhance their well being quite than a chore.
My first suggestion is at all times to repot outdoors in case you can. Even in case you attempt to include the soil as a lot as doable, repotting is messy. When you don’t have any outside area, lay down some newspaper to catch the soil, making clean-up painless.
Select A New Container
Earlier than you contact any of your houseplants, you’ll want to search out their new container. Though design and materials at all times play a job, measurement is a very powerful consideration when repotting. Sadly, it’s also one thing gardeners usually get improper.
When you assume selecting a a lot bigger pot will assist your houseplants develop faster, I’m right here to dispel that fable. Containers which can be too giant really inhibit progress and may even result in fungal progress because of the additional soil (and subsequently additional moisture) across the roots.
For many houseplants, select a container round one or two sizes up. This may be adjusted primarily based on the expansion stage – for instance, a smaller Monstera can develop fairly giant in a number of months in the precise situations, presumably requiring a barely bigger container. However typically, go two sizes up at most to keep away from stunting progress.
When you’re solely repotting to replenish the soil and your plant hasn’t grown a lot, you may take away the previous soil and replant in the identical container. You may additionally wish to trim the roots to reinvigorate them earlier than planting within the new soil.
Put together Your Soil Combine
Talking of soil, the following factor to contemplate is soil combine. Houseplants are fairly specific in regards to the soil they develop in and don’t recognize modifications in situations. You may’t simply collect any soil from the backyard and hope for the very best.
Tropical houseplants typically require a lightweight and ethereal houseplant combination to stop probabilities of rot. My customary combine is 2 components potting soil, one half coconut coir, and one half perlite, however you may regulate the ratios as wanted.
Succulent crops have barely completely different necessities. To match the dry and gritty situations of their native habitats, search for a specialised succulent and cacti combine that drains rapidly.
Orchids even have completely different preferences, rising greatest in orchid bark to swimsuit their usually epiphytic roots. They want extraordinarily good drainage, and the damp orchid bark is usually sufficient to fulfill them.
Analysis the wants of your houseplants earlier than deciding on a soil combine. You can too have a look at the present soil combine to resolve on the best elements, limiting potential points with transplant shock.
Take away The Plant
With the preparation out of the way in which, you may lastly get into the nitty gritty of repotting. This begins with the best process – eradicating the plant from its present container.
In case your houseplants are fairly overgrown, they’ll normally pop proper out of the container with none points. Ensure you elevate from the bottom, avoiding grabbing the stems and leaves. The much less injury you do when repotting, the faster the plant will get well.
Houseplants could get caught of their containers, making them more durable to take away. I discover this occurs usually with terracotta pots, quite than plastic, the place the plant slips proper out. If that is so, you may run a knife alongside the sting of the pot to launch the roots or gently squeeze the edges if the pot is malleable.
If there may be resistance, don’t pull from the highest. The very last thing you wish to do is separate the stems from the basis system by pulling too exhausting. As a substitute, flip the pot on its aspect and gently shake the plant out with out pulling.
Tease The Roots
The subsequent step is essential, particularly if the roots are wrapped round one another.
Pull the roots aside along with your fingers, utilizing a delicate raking movement to loosen them. This can assist them develop downwards and outwards into the brand new soil quite than staying caught the place they’re. Additionally, tease the roots on the aspect – you need these to develop outwards too.
When you’re teasing the roots, take away among the previous soil across the roots. This makes method for recent and high-quality potting soil whereas providing you with a better have a look at the basis system.
Take the chance to examine the roots for indicators of harm. Trim any lifeless or mushy roots, eradicating injury and serving to the plant produce new and wholesome roots to gas progress.
Whenever you’re able to pot up, fill the underside of the container with a little bit of soil, making certain the bottom of the plant will sit slightly below the rim of the pot. To cease soil from spilling out the underside, cowl the drainage holes with espresso filters. This enables extra moisture to empty via however prevents the soil from dropping out.
Decrease the plant contained in the pot and fill within the surrounding gaps with extra soil combine. You wish to fill as much as the identical soil line the plant was beforehand. Masking the stems and leaves or leaving them extra uncovered will result in issues with progress.
Fill the pot as much as slightly below the rim of the container. You don’t wish to fill it to the very prime as this may trigger soil to spill out whenever you water for the primary time. Go away slightly respiratory room to keep away from pointless mess.
When you’ve crammed the container, press gently across the base of the plant to settle it in place. This removes any giant air pockets and allows you to know if it’s essential add extra soil. Don’t push too exhausting – you don’t wish to compact the soil.
Whenever you’re carried out repotting, it’s necessary to water your crops to saturate the soil and settle the roots. Since they don’t like being uncovered to the air, watering will assist them set up within the new soil, boosting new progress.
You may wait a number of days earlier than watering succulent crops like Echeveria or Aloe, as they like dry soil situations. Nonetheless, in these circumstances, the potting soil must be barely damp earlier than planting so that they aren’t left fully with out moisture.
Exchange The Plant
When you’ve completed repotting (and cleaned up the mess), transfer your plant again to the place it was initially. The less modifications in situations the plant experiences after repotting, the sooner it’s going to bounce again.
Repotting is a houseplant care process that may’t be skipped, it doesn’t matter what you’re rising. However in case you perceive your plant’s wants and observe these simple steps, you received’t have any hassle getting it proper.
