My best attempt to ask a convoluted question. I know what I list below doesn't apply to EVERY plant, but this is in regards to what I consider the average house plant's needs.
I know that no plants like to be overwatered, that pots with drainage are best, soil with good drainage is important, and roots don't like to sit in water. I haven't had plants for long but I think I'm a decent judge of when plants need water and when is too soon.
That being said, there are a few plants I own that take forever for their soil to become dry. It's not a puddle of water, but it stays consistently / evenly moist for much longer than my other plants. An example here is a Grape Leaf Ivy I purchased a few weeks ago. The soil was moist when it arrived, and it still is after at least 3 weeks.
Is this something I should be concerned about for any reason? I suppose I worry about mold or root rot or who knows what. Just not sure if there's something I should be changing, or if it's the soil the plants came in and I should change that or if they aren't getting enough light, or what!
