Fertilizing Your Astilbe Plant:
The Dos and Don’ts

Astilbes are a popular plant among gardeners because of their beautiful and colorful flowers. However, to keep these plants healthy and vibrant, it is important to fertilize them properly. In this article, we will discuss the dos and don’ts of fertilizing your astilbe plant.

Dos

Do Use Organic Fertilizers

Organic fertilizers are a great option for astilbe plants. These fertilizers are made from natural materials like compost, bone meal, and fish emulsion. They not only provide essential nutrients to the plant but also improve soil health. Using organic fertilizers will also reduce the risk of chemical buildup in the soil.

Do Fertilize at the Right Time

Astilbe plants should be fertilized in early spring before new growth appears. This will give the plant the necessary nutrients to bloom successfully. You can also fertilize again in mid-summer if you notice that the plant is not growing as well as it should.

Do Follow the Instructions

Always follow the instructions provided by the manufacturer for applying fertilizer. Over-fertilizing can be harmful to your astilbe plant and can cause burns on the leaves or even kill the plant. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.

Do Water Your Plant After Fertilizing

After fertilizing your astilbe plant, make sure to water it thoroughly. This will help the fertilizer penetrate into the soil and reach the roots of the plant. Watering also helps prevent burning of the leaves due to excess fertilizer.

Don’ts

Don’t Fertilize Too Much

Over-fertilizing your astilbe plant can do more harm than good. It can cause salt buildup in the soil which can damage the roots of the plant. Moreover, too much fertilizer can cause excessive foliage growth and fewer blooms.

Don’t Use Chemical Fertilizers

Avoid using chemical fertilizers on your astilbe plants. Chemical fertilizers contain synthetic ingredients that can harm beneficial soil organisms and pollute water sources. They can also create imbalances in soil pH levels, which can affect plant growth.

Don’t Fertilize During Winter

Winter is not a good time to fertilize your astilbe plant. During this time, the plant is dormant, and applying fertilizer can cause nutrient leaching or runoff from snowmelt or rainwater.
