Deadheading your perennials during the hot summer months will encourage longer bloom time and help to keep foliage full and healthy throughout the season. Some perennials just need to have spent blooms removed, whole others that have a heavy bloom all at once might do better with a short cutting back of all blooms (about 1/3 of the plant).
Also remember that wilting perennials in the hot summer months doesn’t always mean they need more water. High temps also cause plants to wilt. So if you have recently watered and your perennials are wilting, be sure that you check the soil before watering again. It is best to let the soil in your perennial garden get to the dry side before watering again as most perennials are not happy with continuously wet soil.

Annuals Flowers and Planters
You may see that some of the flowering annuals that you planted this Spring are now heavily rooted and thriving in the heat of summer. Many tropical annuals love the long, hot days and really start to show off in August and September. For example, have you driven by the front landscape at Fairview in late summer? It’s absolutely bursting with color from our Fairview grown annuals that were planted in early Spring. These plants have been watered and fertilized regularly so that their roots are strong enough to handle the stresses of late summer.
If you notice that some of your annual plants are not looking so stellar, you may be able to give them a healthy “hair cut” (pruning) in early August and allow them to have one more nice flush of new growth and blooms before fall. Be sure to fertilize and water regularly to encourage this new growth. If your plants just need a general cleaning, then a light deadheading to get rid of any old or dead flowers that could create problems is a great step. By removing any old or dead flowers and leaves you greatly reduce the risk of fungus and diseases from occurring on your plants.
As the season progresses, plants in hanging baskets and containers often require more and more water. This is because the roots continue to grow in limited space and take up much needed soil space for water retention. Continue to water at least twice a day but if the watering gets too much, it may be time to replace. Replace any dead or dying plants with fresh new ones that will really create a pop of color and show off the other plants in the container. Make sure to choose plants that can take the same amount of sunlight and water as the other plants that are already in the container. Then add some fresh soil around the roots of the new plants.
