Q.Do spider plants prefer an acidic or alkaline soil?
My spider plants were transplanted a few months ago (November) and they were doing fine for a while, but we had some high temperature days in Southern California (high 80’s and more in Feb and March). Since then the leaves (not just the tips) are turning brown/black from the newest growth outward; coincidently at the same time I started watering straight from the water faucet in the sink, rather than using water that had been sitting out in a container for a few days.
What location were the spider plants transplanted to? Maybe that location was not ideal? Spider plants will get leaf burn if they receive exposure to direct sunlight. They should be in a location where they receive high, indirect light.
Spider plants also enjoy cooler temperatures (55-65 degrees) more than hot ones. They usually do not like temperatures above 80 degrees.
A spider plant prefers a soil pH of 6.0-7.5 so it is somewhat neutral.
Tip burn in spider plants is caused by the fluoride and chlorine in tap water, so be sure to go back to using rainwater or distilled water.
