Why should you fertilize Milkweed? Native plants do very well without much assistance, so feeding Milkweed may seem unnecessary. This low-maintenance perennial can do well without fertilizer, but amending the soil or applying plant food can keep the plant healthy and thriving and increase the growth rate. Find out what you need to know about fertilizing native and Milkweed and tropical Milkweed and how to enjoy a mature, established plant that comes back year after year.
How to Fertilize Milkweed
The easiest way to support Milkweed plants is to amend the soil with organic compost or fertilizer. Milkweed is not a heavy feeder; providing quality, nutrient-rich soil will support plenty of new growth. The ideal soil mix will be fertile and slightly acidic. Balanced, water-soluble fertilizer is another option to help Milkweed plants grow. Increasing fertilizer dosage to encourage more growth can be tempting, but over-fertilizing plants can be a problem. Applying a large dose of fertilizer may cause fertilizer burn or even kill the plant.
Best Time To Fertilize Milkweed
Early in the growing season is the best time to feed Milkweed plants. Mix in organic compost or manure when planting new plants, or top-dress the soil for established plants. A single application of fertilizer in the spring is enough to support the plant throughout the growing season.
Best Fertilizer For Milkweed
A balanced, all-purpose fertilizer with a ratio like 10-10-10 or 20-20-20 is a good option for Milkweed. The number or ratio of the fertilizer refers to the amount of nitrogen, phosphorus, and potassium in the mix. Some plants need more of one nutrient over another, but Milkweed thrives with a balanced diet.
