Torenia is a low-maintenance flowering plant with a compact form. As an annual, you may wonder, does Torenia need to be fertilized? Yes, the Wishbone Flower will look its best and provide consistent blooms when fertilized all summer. Plants grown in beds, borders, or containers are not naturally exposed to minerals and nutrients, so feeding the plants provides a boost of nutrition that will help the plants thrive.
How to Fertilize Torenia
Torenia grows well in rich soil with high organic content. Amending the soil with organic compost or manure when planting will ensure the plants get off to a strong and healthy start. You can give the plants an additional nutritional boost by applying fertilizer every few weeks from spring planting through the fall frost. Depending on your preference, you can apply a water-soluble or slow-release granular fertilizer. Overdoing it can cause more harm than good, so always follow the instructions on the packaging when applying fertilizer.
Torenia prefers soil with a neutral to acidic pH. Advanced gardeners may want to test the soil and adjust accordingly to best prepare the plants for success.
Best Time To Fertilize Torenia
Torenia can handle continuous fertilization throughout the growing season. Default to the instructions on the packaging, but generally, every few weeks is good to give the plant the nutrition necessary to push out new growth and thrive. As an annual, the Wishbone Flower will die after a heavy frost, so it is not necessary to fertilize during late fall once the weather turns chilly.
Best Fertilizer For Torenia
Torenia is an adaptable plant that does best with a balanced fertilizer, like a 10-10-10 or 20-20-20. As a flowering plant, a balanced fertilizer provides the proper nutrition to support both foliage and flower production. A balanced plant food, like Miracle Grow, is suitable for Torenia.
