Fertilizing is a very broad and large topic. Each plant in your garden could have different needs as far as when to fertilize, how much to fertilize, and what type of fertilizer to use. You just have go to your local garden center and look at all the different types of fertilizer they have and you will see what I mean, it’s overwhelming.
I am not going to attempt to get into the science of fertilizer in one blog post. Here I will just try to touch on some basic and general guidelines for fertilizing your flower beds.
First and foremost, it’s important to understand that you can harm your plants if you use too much fertilizer or fertilize at the wrong time. As far as fertilizer is concerned, more is not better.The best thing to do is to read and follow the directions on the fertilizer package.
Very broadly, there are two types of fertilizer; slow release fertilizers and liquid fertilizers. Slow release types don’t need to be applied very often and last longer, while liquid types benefit the plants faster but will need to be applied more often.
Here are some other tips:
- Don’t fertilize during the dry hot summer months, or when a plant is dried out. Plants that are very dry will soak up the fertilizer much quicker than plants that are well hydrated. The risk of burning your plants with fertilizer is much higher during this time.
- Plants that have fertilizer burn will look wilted and dried out, similar to plants that are under watered. If you over-fertilized a plant, the best thing to do is water, water, water and try to dilute and wash away the fertilizer as much as you can.
- Stick with a balanced, general purpose fertilizer if you are planning to fertilize your whole garden at once.
- Keep dry fertilizer off the leaves of your plants as it could burn the leaves. After spreading the dry fertilizer, water the your gardens well so the fertilizer will start to soak in.
- Some slow release fertilizers last several months, and it’s good to apply a slow release fertilizer in the fall to give your plants the boost they need in early spring.
- With liquid fertilizers, generally perennials should be fed in early spring and once or twice during the summer months.
- Spread the compost from your compost bin in your flower beds for a natural fertilizer. Well composted organic materials won’t burn your plants, are much less expensive than chemical products and compost works great.
