Impatiens are low maintenance and fast-growing, so you may wonder why you should fertilize this plant. Fertilizing newly planted Impatiens will give the plants a solid start and promote a healthy root system. Routine feedings will stimulate new growth and plenty of striking flowers throughout the growing season, so your plants will thrive and look amazing.
How to Fertilize Impatiens
Impatiens like rich soil, so mix organic compost or manure into the soil when planting. The nutrients will help the plant settle in and encourage new growth. When it comes to applying fertilizer, you have two options. Use a slow-release fertilizer during the spring and again halfway through the growing season.
Water the plant before applying fertilizer because this will help the roots absorb the nutrients and prevent fertilizer burn. Another option is to use water-soluble plant food every couple of weeks. A water-soluble fertilizer can be incorporated into your watering routine. Always follow the instructions on the packaging when using fertilizer.
Soil should be slightly acidic and have a pH of 6.0 - 6.5 for Impatiens. If you are an advanced gardener, you may want to test the soil to determine the pH so you can select an appropriate plant food.
Best Time To Fertilize Impatiens
The best time to fertilize Impatiens depends on the type of plant food used. Slow-release fertilizers need to be applied during the spring and partway through the growing season. Water-soluble fertilizers should be applied every two weeks. If using a water-soluble plant food, it can be applied when you water the plant.
Best Fertilizer For Impatiens
We recommend a balanced all-purpose fertilizer with a 13-13-13 or 10-10-10 ratio. You can also use a generic plant food like Miracle Grow for Impatiens. It is especially helpful for plants growing in containers, as those plants typically need fertilizer more than plants growing in the ground.
