Well, you are now fully in the know about fertilizing your plants. If you feed your plants at key times, you should be fine.
However, if your plants begin to look weepy it might be a sign they are in need of nutrients. Plants have a way of letting you know when they are in need.
Too many people overlook the importance of fertilizing indoor plants. However, proper feedings are essential to grow healthy, beautiful plants.
Houseplants wilt when they need water. Their leaves grow pale and lanky when they aren’t getting enough sunlight. When the humidity is too low, they turn crispy; when it’s too high, they may develop rot. But, knowing when your houseplants need to be fertilized is far trickier. There’s no clear signal from your plant that shouts “Hey, it’s time to feed me!”, other than perhaps slowed or stagnant growth, which for many houseplant parents, is barely noticed. So, instead of waiting for a signal from the plant, you’ll have to take matters into your own hands and use houseplant fertilizer on a schedule that’s based on their growing cycle.
Each specific houseplant has slightly different needs when it comes to houseplant fertilizer amounts and frequency, but there’s no need to overly complicate the process. Yes, you could study up on each individual houseplant species you care for, determining its specific nutritional needs, but the truth is that the vast majority of common houseplants have fertilizer requirements that are similar enough that treating them in a singular way is more than enough to satisfy their nutritional needs. Some houseplants are heavier feeders than others, it’s true.
Start fertilizing houseplants about 8 weeks before the last expected spring frost. This is when the days begin to lengthen noticeably and houseplants shift from a semi-dormant state into a period of active growth.
