HOW TO RE-POT YOUR PLANTS
The time has come to start repotting your plants; here are some tips which will help.
What plants to repot?
Pot only those plants where monsoon triggers new growth. Except cactus and succulents and adeniums most of the plants can be repotted now.
Why to repot?
- Stunted growth
- Fruiting plants not bearing fruits or flowers
- Need to trim and shape the plants
- Plants have become pot bound
- Soil has drained out and the plant has utilized all nourishment
- Plants seems to have lost the vigor
Constituents of a good potting mix –
- Fresh garden soil – preferably taken from under a tree with lots of organic mix, sorted and sieved for any seeds of weed grass etc
- Good old cow dung manure or vermicompost – it should not smell foul, should be dark and fluffy, should not clump – this also needs to be sorted for any seeds and weed grass etc
- Cocopeat – soaked for a day and then water changed three times so that the ph value comes to neutral
- Course river bed sand – filtered out via a mosquito mesh, use what is left on top of the mesh – discard what comes from beneath
- Broken pieces of terracotta pots or clay pots – to be put at the base of the pot
- Charcoal – medium size pieces – as a layer over the broken pieces of terracotta pieces
- Bonemeal
- Neem Cake – powder – de oiled
- Perlite
- Vermiculite
- Fungicide
- Micronutrient
- DAP – di ammonium phosphate – adding this will need maturing for 7-10 days
- SSP – single super phosphate – adding this will need maturing for 7-10 days
- Lindane or malathian dust
- Gypsum powder form for area which have hard water or the soil has high ph
- Humic acid – liquid or granules
Preparing the pots –
- Get your pots washed – terracotta/ceramic/plastic/any other material – wash these in hot water, rinse properly and keep them to dry, clear out drainage holes at the base and make more holes if there is only one, ideal to have at least five holes at the base of the pot one in the center and four on sides
- Go for a one size bigger pot if the plant has over grown the pot, its ideal to give ample space on all the sides of the plant in the pot so that the plant gets ample space to grow.
Potting mix
- Use the potting mix formulae given in the chart
- Keep the mix for maturing for a week or ten days for best results
- If anything is not available from the list then increase any of the top 1-4 item proportionally
- If you want to use organic options only then use substitutes for inorganic ingredients
Preparing the plant
- Water the plant properly a day before repotting.
- Tap the plant out slowly and carefully from the pot, do not in any case wrench the plant out from the pot this will cause the roots and in some case stem of the plant to break
- Ideal is to tap the pot on a hard surface softly and slowly invert the pot and take the plant out
- Now remove carefully any root web which has been formed on the sides – this root web is an indication that the plant is root bond
- Do not in any case break the center root ball of the pot
- also be very careful in cutting the tap root if it has over grown
- care should be taken that more than half of the small roots are left intact
- root ball should not be broken at any cost
- trimming can also be done with branches etc for the top of the plant, lanky plants should be trimmed to give a more fuller look, use your creativity and shape your plant as per your liking
- but do not in any case chop the whole plant off unless ur sure that it will grow back again, this will differ from plant to plant
Potting the plant
- After choosing the right pot, check the drainage holes use a layer of terracotta pieces to cover the 5 holes at the base
- Cover these terracotta pieces with charcoal, this will allow proper drainage
- Fill some of the potting mix at the base and place your plant in the center of the pot
- Fill rest of the potting mix on the sides and add more soil to fill the potting mix upto the brim of the pot, ensure that the plant is fixed in the pot properly and would not topple over
- Do not leave any space at the top as the soil mix will surely settle and go down
Watering the plant
- Make a solution of humic acid @ 5 gram + fungicide @ 5 gram in a liter of water
- Use this fungicide humic acid mix to Water the plant lightly at first then properly so that the soil mix gets settled in the pot
- If the level goes down too much or the plant tries to topple over add more potting mix water again
- Ensure that excess water is draining out from the holes beneath the pot
Placement and post potting care
- Place the plant in a semi shade area, do not expose to hot sun in any case for the initial 2 weeks
- you can add Leca balls, hydroton, stone chips (not marble chips) at the top to cover the mud, this will save the mud from overflowing and also save your floors from getting dirty
- drainage tray could also be used under the pot to collect excess water
- if your plant is a sun loving plant then u can shift it from semi shade to full sun over a month
- do not keep the pot where water gets logged
- monsoon rain will benefit the plant and give it good growth
- start with feeding the plant after you see new growth
- feeding for the growth period is done with balanced npk 20-20-20 @ 2 gram per liter every
- fungicide is given with npk @ 5 gram per liter of water
- micronutrient is given once a month @ 1 gram per liter of water
