Their long, narrow leaves come in different shade of green, bronze, purple and some have variegated foliage. New Guineas branch well, are sturdy, and grow taller than standard impatiens. Most are 1 to 2 feet tall. Standard impatiens are easy to grow and are generally smaller than New Guineas. They prefer shady areas and become carpeted mounds of color.
They can become leggy over the summer, so it is good to pinch or scissor them back and they will flush back up again in a week or two. From partial shade to full shade, New Guinea Impatiens and standard Impatiens will give you an amazing show all summer long in a huge array of colors. They both love water so keep them moist but not soggy. Use well-drained soil and mulch the top of the soil around the plants to retain moisture. Fertilize often or use a slow-release fertilizer.
Hi Jeanie, have you tried Griffin Greenhouse Supply? They are a broker of many growers and should be able to find you impatien plugs, I know we get ours through there. There are Sunpatiens which look just like New Guinea Impatiens and they would probably be able to take that kind of sun since they can withstand more than the New Guineas.
Regular impatiens do very well in Hawaii, but they do best in shady areas of the yard. I live on Oahu and my backyard is filled with impatiens! When it comes to vinca care, you can take a hands-off approach at this point. Vinca will bloom and thrive despite hot weather and drought. After the first successful year of growing vinca plants in your garden, it's unlikely you'll need to purchase transplants again or start seeds indoors. Vinca readily reseeds and should come up again each year.
According to the International Environmental Weed Foundation, impatiens are native to east Africa, so like vinca, they are grown as annuals in the U. Transplant impatiens after all threat of frost has passed in the spring. The Old Farmer's Almanac recommends spacing transplants 8 to 12 inches apart if a low-lying ground cover is desired. However, you can force impatiens to grow up to 30 inches tall by spacing them closer together. Impatiens also thrive in nutrient-rich soils with a neutral pH, so amend the planting site with plenty of compost if needed.
Keep impatiens well watered so that they don't dry out but do not allow their roots to become soggy. Choose a planting site that provides some protection from the wind and some shade during the day.
Consider planting them along an east-, west- or north-facing wall or fence. You want them to face away from the typical prevailing winds in your area while also staying out of full sun, which shines with the greatest intensity on south-facing walls and fences in the northern hemisphere.
Should I prune it back and if so what is a good time to do this? My hydrangeas suffered from heat scorch last summer so I cut them back all the way to the ground. Uh oh. I think I made a huge mistake as they are not blooming at all this summer however they are green and lush! What should I do? Should I prune them or just leave them alone?
Hi, Mary. I would just leave them alone for this season. It just may not come back as full before the end of the season. For larger, more traditional grass varieties, Panicum Shenandoah is a lovely variety, along with Little Bluestem grasses.
All of my Knockout Roses 25 bushes have developed Rosette Disease. I hate to dig up all my once beautiful rose bushes. What should I do?? Also, what types of roses are resistant to Rosette Disease? I have two different wisteria- amethyst falls and blue moon. My amethyst falls has gotten out of control now and needs major pruning. Thank you! I have a hydrangea that I thought was snowflake but is not bright white.
It more of a cream color. Do I cut this down halfway in the fall? What about coreopsis? I thought they were a great late summer plant and deer resistant but lately while some varieties have done very well, the pale yellow one with asparagus-like foliage Moonbeam? Hi, Judy. Unfortunately, there is no current treatment for Rosette Disease outside of discarding the plants themselves, and to my knowledge, there are no rose cultivars that are resistant to it.
You can certainly cut them back, but I fear that is just a temporary solution and the disease will just manifest again over time. If they indeed confirm your suspicions of Rosette Disease, unfortunately, removal may be the only option.
Hi, Renee. However, doing this will prevent blooming for a year or two until new shoots begin to mature. Hi, Kerry. Mike — what about creek bed plants? I need to protect my creek bank — and most of it is in shade.
What can I plant to build a root system that can handle shade and occasional flooding? Hi Cathy.
