What's the best way to transplant houseplants, that are established in water, into soil?

A friend gave me some 'baby' spider plants + another unknown name rooted houseplant. i've been keeping them all in water for months now. i heard that sometimes waiting too long to plant them in soil can make successful transplanting difficult. is there a special potting soil mix i should buy or should i just keep the soil extra wet for the first week?

Plunkem in potting soil, water, wait. No big thing. spiders are very difficult to kill. I've had them and other things growing in water for years. Little or no impact (shock) when transferring to soil.
Reply:This one is easy. Keep the plant wet for the first week. Then do the transplant. It has worked for me in the past, i haven't tried the spider plants but im thinkin they should work.
Reply:there is no trick to that really just till or losen the soil really good and pu them in cover the roots and water really well for a couple of days plant them when the sun is down this will reduce the stress on the plant and you should be fine
Reply:If they have a good root system go ahead and plant them in a good potting soil. Just keep it moist,don't over water them.
Reply:Spider plants are the hardiest little blighters in the world. Just get any sort of compost and put it in a pot make a hole with your finger, pop in the spider plantlet and gently firm the compost. They are so easy to grow that they are hard to kill. Don't waste money on 'special' compost or fancy 'fertilizers' save that for your orchids.

The other plant might need some gentler handling. Put it into loose compost and keep it well watered and let the watering settle the compost around the roots. What you have to avoid is breaking of the formed roots. Good luck
