Common problems with perennials and how to solve them

Problem: Perennials not blooming or blooming less

Cause: Poor soil, lack of sun, over-fertilizing, insufficient water

Solution: Plant perennials in well-draining soil that's rich in organic matter. Provide adequate sun, keeping in mind the specific light requirements of each plant.

Don't over-fertilize, as this can discourage blooming. Regularly water your perennials, especially during dry spells.

Problem: Perennials wilting or looking limp

Cause: Lack of water, disease, pests, over-fertilizing

Solution: Water your perennials regularly and deeply, making sure not to let the soil dry out completely. Check for signs of disease or pests, such as fungal growth or holes in leaves. If you suspect either, treat promptly with an appropriate pesticide or fungicide.

Avoid over-fertilizing, which can result in too much lush, green growth at the expense of blooms.

Problem: Perennials growing too large or sprawling

Cause: Over-fertilizing, lack of pruning.

Solution: Avoid over-fertilizing your perennials, as this can encourage rampant growth. Prune regularly to maintain the desired shape and size, cutting back any leggy or sprawling growth.

Problem: Perennials not returning the following year

Cause: Poor soil, lack of sun, too much moisture.

Solution: Plant your perennials in well-draining soil that's rich in organic matter. Provide adequate sun, being mindful of the specific light requirements of each plant. Avoid overwatering, as perennials can rot in consistently moist soil.

Frequently asked questions about planting, growing and caring for perennials

Q: When is the best time to plant perennials?

A: It depends on where you are and the types of plants you're working with. Generally, spring and fall are ideal because the soil is warmer and gives the plants enough time to establish roots before winter.

Q: How do I choose the right perennials for my garden?

A: As for choosing the right perennials for your garden, there are a few things to keep in mind. You should consider the amount of light and type of soil in your garden, as well as the specific look and vibe you're going for. It's also important to think about your hardiness zone and the particular needs of each plant you're considering.

Don't hesitate to consult with a gardening expert or look for guidance in books and online resources. With a little research, you'll find the perfect perennials to make your garden shine!

Q: How do I plant perennials?

A: Prepare well-draining, nutrient-rich soil. Dig a hole for each plant that's large enough to accommodate its roots, and plant at the same depth as the plant was growing in its previous container or location.

Backfill the soil around the roots, gently tamping it down to eliminate any air pockets. Water the plant well to help it settle into its new home.

Q. How do I care for perennials after planting?

A: After planting your perennials, it’s important to keep the soil evenly moist but not waterlogged, especially in the first few weeks after planting. This will help the plants establish a healthy root system.

Apply a balanced fertilizer after a few weeks, and then as needed throughout the growing season. Be sure to prune back any leggy or sprawling growth to maintain the desired shape and size. And keep an eye out for any signs of disease or pests, treating them promptly as needed.

Q: How often should I water perennials?

A: The frequency of watering needed for perennials depends on the soil type, weather conditions, and specific requirements of each plant. In general, it’s best to water deeply and regularly, allowing the soil to dry out a bit between waterings.

Don’t let the soil dry out completely, but be mindful not to overwater, as perennials can be susceptible to root rot in overly moist soil.

Tips for successful perennial gardening

To get the most from your perennials and ensure they thrive year after year, here are some tips for successful perennial gardening:

1. Choose the Right Plants: Select plants that are well-suited to your location and conditions. Consider the amount of light, type of soil, and hardiness zone, as well as the unique needs of each plant you're considering.

2. Prepare the Soil: Perennials love soil that drains well and has plenty of organic matter. You can add compost or other organic materials to improve the soil's structure and fertility.

3. Plant at the Right Time and Depth: Timing and depth are crucial. Spring and fall are generally the best times to plant, depending on the specific plant's requirements. And be sure to plant at the right depth, as planting too shallow or too deep can have an impact on the plant's growth and overall health.

4. Water Regularly: Water deeply and regularly, being careful not to overwater or underwater. A good rule of thumb is to water deeply once a week, allowing the soil to dry out a bit between waterings.

5. Fertilize Appropriately: Apply a balanced fertilizer after planting, and then as needed throughout the growing season. Avoid over-fertilization, which can encourage too much growth at the expense of blooms.

6. Prune Regularly: Prune back any leggy or sprawling growth to maintain the desired shape and size, and to encourage healthy new growth.

7. Watch for Signs of Disease or Pests: Keep an eye out for any signs of disease or pests, and treat as needed.

By following these tips for successful perennial gardening, you can enjoy a beautiful and thriving garden of perennials for years to come. Happy gardening!
