Healthy Hanging Baskets All Summer Long

Sandi Marr


By July, our hanging baskets start looking tired. Here are a few tips to rejuvenate them for the rest of the summer.

Prune. Often the centre of a hanging basket begins to die out. Redirect growth to the top of your hanging basket by pruning. Trim about one third of the growth on the sides of your hanging basket to encourage growth in the centre. Be sure to regularly deadhead spent flowers.

Water thoroughly. A good rule of thumb is to water until water runs out the bottom of the container. It is best to water in the morning or evening (or both, in extreme heat).

Fertilize. High phosphorus (the middle number) keeps flowers blooming.

Rotate. Often hanging baskets are hung on a porch or other place where they are exposed to sunlight on only one side. In that care, it is important to rotate the baskets for even growth.

Plan ahead. When you purchase a hanging basket in May or June, be sure to look for a 12 or 14 inch pot size. A 10 inch basket will dry out too quickly. If you purchase a 10 inch pot, transplant it into a 12 or 14 inch size for best results.

As your hanging baskets continue to bloom and look their best, enjoy these warm summer months. After all, we deserve some hot days after our long Canadian winters

Thompson Creek Eco Centre – Reboot

Debbie Thomas & Dan McKay

The Dunnville Thompson Creek Project was started over 20 years ago by a group of organizations headed by the Dunnville Bioregion Association. It was one of many possible projects identified at a week long workshop organized to develop a sustainable development plan for the Town of Dunnville.

The project involved the restoration of a 45 acre site of community owned property that included Thompson Creek which was seriously degraded and in need of remediation.

It was identified as an ideal opportunity to rehabilitate the creek as well as plant a Carolinian Arboretum, establish a Wetland Complex and Tall Grass Prairie Plantation. All of which would be used as a outdoor education facility for local schools as well as providing a naturalized walking trail system for the community.

Over 800 trees were planted by volunteer groups,  all Carolinian species were incorporated. A riparian zone was restored along the creek banks. Ducks Unlimited restored a wetland in the 35 acre field and planted it with native Tall Grass species and native wildflowers.The local Ducks Unlimited committee built the existing pavilion on site, in hopes of it becoming an outdoor classroom. However the original plan stalled allowing Mother Nature to take over. The Carolinian trees grew, the Tall Grass flourished, the Wetland regenerated and the Creeks health improved. Fast forward Dunnville Horticultural Society fresh off the success of the Dunnville Centennial Park and Fountain restoration, was approached by Dan Mckay one of the original members of the Bioregion Association. Dan felt DHS was the perfect organization to partner with and take up the challenge to complete the original project and finish the trail system.

Dunnville Horticultural Society has since secured permission, along with a partnership agreement and grant from Haldimand County. Dan Mckay is the Project Coordinator with DHS Pres. Debbie Thomas as co-chair. DHS is pleased to announce the trail system including outdoor educational components will be known as  Thompson Creek Eco Centre. The motto will be Restore-Educate-Preserve. It will have four distinct ecological cells. They will each have a trail system, species identification signs, large color information panels describing each of the cells habitat and ecology as well as its wildlife residents.

The four cells include Carolinian Arboretum, Creek Restoration, Wetland Complex and Tallgrass Prairie. The trail around the prairie is 1.5 km, the other trail areas will be shorter providing for all hiking levels. The future hope is to link these trails to The Trans Canada Trail and the town’s existing Rail Trail that runs along South Cayuga St. from Cedar St. The parking lot at Centennial Park where the Fountain and Muddy reside, will have a large map directing the public to the the various eco cell locations. Signage will have QR codes linked to various information websites to  learn about what species, flora and fauna reside within. Fundraising efforts and work on site has begun with the routing of trails. DHS has coordinated with professionals that will assist with the eradication of invasive plant species this fall (phragmites) with a controlled burn planned for the Tallgrass area early next spring. The Project is expected to be complete by fall of 2019.

DHS is seeking public support, and is a non profit registered charity #886092816RR001.

Gardening Tasks for May

Sandi Marr


We’d all agree. Spring has been a long time coming. But it feels like it is finally here. Let’s begin our gardening!

Rake up winter debris from flowerbeds. Break off wilting tulip or daffodil heads and allow the foliage to die back naturally.

Lightly side dress perennials with an all-purpose fertilizer. Avoid spilling the fertilizer on the plant, and use care not to damage the shallow roots when you cultivate it into the soil. Spring is a good time to divide perennials.

Prune back early flowering shrubs such as forsythias, weigela and spirea by one third when they have finished blooming.

Remove the wilting seed heads from rhododendrons and azaleas so that the plants’ energy
can go to foliage growth and next year’s flowers, rather than seeds.

Lilacs should be fertilized (10-10-10) and pruned after they finish blooming, removing sucker growths and dead blooms.

Roses, deciduous shrubs and trees may be fertilized (10-10-10). Be sure to water the fertilizer in thoroughly after it is applied. Keep an eye on the roses, spraying for aphids and other diseases such as black spot.

Remove any sucker growths from fruit trees. Cut out all the dead canes from your raspberry patch. The new canes that will bear this year’s fruit should have new, swollen buds along the edges. Thin these to five canes per foot of row to allow good air circulation and prevent overcrowding.

May is a perfect month to repair your lawn. Visit your local garden centre for a good quality lawn care seed and fertilizer.
