Remove about one-third or more of the old potting mix surrounding the plant's roots. As it grew, your plant removed some or all of the nutrients in the current mix, so you'll want to give it fresh potting mix or soil. Pour a layer of fresh potting soil into the empty planter and pack it down, removing any air pockets.
Do You Keep Old Soil When Repotting? Removing the soil from the roots depends on a number of factors. It's important to understand that discarding old healthy soil can cause damage to your plant's roots, while leaving moldy soil can cause your plants health to deteriorate.
When it comes to choosing a pot, size is everything. If your plant isn't rootbound or overcrowded, but its soil is becoming hydrophobic or disintegrating, repotting your plant into the same container (or one of the same size) with fresh soil works wonders by refreshing the soil with nutrients.
Top it off: If the level of soil has dropped, add fresh planting mix also known as potting mix. Ideally, the soil comes to within an inch or so of the rim of the planter or raised bed. Use a fork or hand tool to blend the new soil into the old soil. Blend new soil into the old soil.
If the plant itself makes up more than ⅔ of the height, it's time to repot. Not all plants grow taller; some grow fuller or longer (think trailing varieties). The same rule applies, though: Consider repotting whenever the plant seems to outgrow its home, Greene says.
It can be quite normal for plants to temporarily stop growing after repotting, especially if you went up a lot bigger in pot size. What you want to try to avoid is transplant stress, such as yellowing, wilting, dropping leaves, roots that don't recover, root rot or even plant death.
Allow for Good Soil Drainage
For container plants, potting soil should be used and pots must have drainage holes. Any saucers below houseplants should be emptied regularly and plants need to be potted in appropriately sized, not oversized, containers to avoid an excess of moisture in the soil.
Make sure the plant is well watered 2-4 days in advance. You don't want to repot when it's sopping wet but being too dry will cause stress. Take the plant out of the pot. If the rootball is a bit tight, gently massage the roots to loosen them up.
If plants died from bacterial, fungal or viral disease, then you definitely do not want to reuse the soil, as soilborne pathogens can still be present and active. However, if the plants that grew in the soil before were healthy, it is generally OK to reuse the potting soil.
If your plant succumbs to root rot, you can reuse the soil in a new plant, however, you'll have to take a few important steps first, such as sanitizing it (which we describe below).
Water thoroughly after repotting to help the soil settle around your plant's roots. Plenty of moisture will also help your plant recover from the move better. If you have a saucer under the pot, make sure to empty it, so your plant doesn't get too soggy.
Repotting or transplant shock is a state of stress some plants experience after they're moved from one pot to another. It can manifest in a number of different ways, but there are a few key signs.
If you plant a pot-bound plant into the ground or into another pot without first loosening the tangled and overgrown roots, they will continue to grow in a circle rather than reaching out into the soil to anchor the plant.
Hydrogen peroxide can help to control fungal growth and fungal infection, such as root rot, by preventing the growth of fungi. It can also help kill fungus and bacteria on plant roots.
Another product that'll help prevent the spread of root rot is non-flavoured cinnamon. After having removed the dead roots, sprinkle a thin layer onto the healthy tissue before placing into a bed of new compost.
Once root rot is identified, you must determine if the plant can be saved. If the entire root system has already become mushy, it is too late to save the plant. However, if some healthy, white, firm roots exist, try to bring the plant back to good health by replanting in fresh soil with good drainage.
Plants may appear wilted and thirsty, but take care to refrain from watering until about a week after re-potting to ensure that any roots damaged during re-potting have healed. During the recovery period, place plants in a cooler, shadier spot. Most potting soil contains fertilizer.
We advise not to right away, but within the same week of repotting is fine. The Soil should be slightly, naturally moist, so water when the top few inches feel dry as per normal. If you have treated your plant, it shouldn't be a problem again. Lastly do not fertilise your plant after root rot for a few months!
There could be several reasons for a plant dying after replanting, including: shock from transplantation, incorrect planting depth, not enough water or too much water, pest or disease problems, or improper lighting conditions.
The best time to repot a plant is in the spring so that actively growing roots will have enough time to grow into newly added potting mix. There are several signs that houseplants can exhibit when they are pot-bound. First check the frequency you are watering the houseplant.
The growing season, early spring through late summer, is usually the best time to repot your plants. Because your plants are actively growing during this time, they'll get the most out of additional space and fresh nutrients!
Rocks in the bottom of containers do not contribute to better draining soils and healthier plants. Instead plant roots encounter saturated soils that don't drain efficiently. It all has to do with something called a perched water table.
