Choosing the Right Location for Growing Black Eyed Susan

When choosing a location to plant Rudbeckia Hirta, it’s important to consider its growing habits. This plant prefers full sun to partial shade and well-draining soil. It can tolerate a range of soil types, from sandy to clay, but it doesn’t do well in wet or poorly drained soil.

If you’re planting black-eyed Susan in a garden bed, choose a location that receives at least 6 hours of direct sunlight per day. If you’re planting in a container, place it in a location that receives morning sun and afternoon shade.

It’s also important to give Rudbeckia Hirta enough space to grow. This plant can spread up to 2 feet wide, so make sure to plant it at least 18 inches apart from other plants.

Soil Preparation and Planting Tips

Before planting black-eyed Susan, it’s important to prepare the soil properly. Start by removing any weeds or debris from the planting area. Then, loosen the soil to a depth of at least 6 inches and mix in a generous amount of compost or other organic matter. This will help improve the soil’s drainage and fertility.

When planting black-eyed Susan, dig a hole that’s slightly larger than the root ball. Place the plant in the hole and backfill with soil, making sure to press it down firmly around the roots. Water the plant thoroughly after planting to help it settle in.

Watering and Fertilizing Black Eyed Susan

Rudbeckia Hirta is a drought-tolerant plant that doesn’t require frequent watering. In fact, over-watering can cause the plant to rot or develop fungal diseases. Instead, water your black-eyed Susan deeply once a week, or whenever the top inch of soil feels dry to the touch.

In terms of fertilization, black-eyed Susan doesn’t require a lot of extra nutrients. However, you can give it a boost by fertilizing it with a balanced, all-purpose fertilizer once in the spring and again in mid-summer.
