How to Plant Position These Perennials for Maximum Flowering
Planting and positioning your best long blooming perennials correctly is crucial for getting the most out of them. The right spot gives the plant the most sunshine and encourages steady flower production.
Tips for Planting:
- Sunshine - The majority of full sun long blooming perennials require at least six hours of direct sunshine every day
- Soil - Use organic fertilizer mixed into soil that is rich in nutrients and drains well
- Spacing - Make sure there is enough space for air to flow to keep diseases away and let roots grow
Pick wide pots with drainage holes if you are working with containers and make sure to water them often. The majority of the longest blooming perennials for pots, such as dwarf sunflowers and irises, are simple to grow in containers.
Tip: For even soil warmth and water retention, place mulch around the base of each plant. Plants don't get stressed out during the hottest part of summer this way, so they develop longer stems.
Maintenance Tips to Keep Blooms Going Longer
To make flowers last longer, you need to give them regular care. Even the best full sun long blooming perennials require a little assistance to maintain their performance throughout the year.
Steps for Realistic Maintenance:
- Regularly remove the dead flowers to make room for new buds.
- Use a balanced slow release fertilizer once a month.
- To improve roots, water deeply instead of often.
- Lightly cut back the leaves in the middle of the growing season to encourage new growth.
Routine for Seasonal Care
Add compost or organic fertilizer to your plants' soil early in the spring to help them grow faster. Keep an eye out for pests and diseases during the summer. Cut off any dead stems at the end of the season and cover the roots with mulch before the cold.
Perennials like Maximilian Sunflower and Blue Flag Iris can keep blooming for years if you take good care of them. This will keep your garden looking alive and attractive.
