Hardy Mums are Blooming!

Hardy chrysanthemums are in the house at Knecht’s and they’re starting to pop! We dare to you to resist their bushy foliage and carpet of colorful blooms. Swing on by to see our wide selection of upright and cushion varieties that are guaranteed to make your late summer and fall garden absolutely stunning.

If you want maximum mum power, don’t wait until fall to get these beauties in the ground – giving them plenty of time to establish before cold weather hits is essential for winter survival. Choose a sunny site with good drainage and enough room to give these flowering powerhouses the air circulation they need to avoid disease. Don’t forget to work in some compost or peat and a good fertilizer aimed at boosting blooming power!

Mum pro tips: There’s no need to cut mums back for winter; in fact, they have better survival rates when foliage is left to protect the crown. Clean up dead foliage in spring (and be patient, mums can be slow to wake up after our hard winters) and pinch them back a few times before mid-summer for bushy, beautiful plants.

For your fall decorating, we also have kale, some decorator mums, and red rubrum grass.  The fall perennials would include asters and rudbeckia.

Rudbeckia Goldsturm

Thu, 08/08/2019 - 7:02pm

Rudbeckia Goldsturm is one of the most classic perennials.  It has been blooming now in gardens for several weeks and will continue up until frost.   It’s common name is Black Eyed Susan.

It has to make you smile.  The bright yellow / gold flower petals brighten up even the cloudiest of days.   This perennial has earned the title of perennial of the year in 1999.  It can grow in Zone 3 – all the way to Zone 9.  Most of the country.   The height is 18″-24″.  There are different cultivars that are shorter.

If you read the tag of the Goldsturm Rudbeckia – it will say “Full Sun”.  I have three different clusters of them – one on the north side of our house, one on the south side and a smaller cluster out in my hosta garden.  All are growing beautifully right now and look radiant.  Since we live in the woods – the sun on the north side is only a few hours, the hosta garden about half day now that we lost so many trees, and on the south side of our house – it may be about 6 hours of sun a day.   They bloom for months – but start just a little later than those in full sun.

They will self seed – so if you want a contained plant – this might not be the one to choose.  We leave them all winter and cut them down in the spring.  The seed heads add winter interest to the garden as well as a food source to the wintertime birds.  There is something special about seeing a little Chickadee going after the seed heads with snow coming down.  

Pair the Goldsturm Rudbeckias with Coneflowers  and you will have a minature prairie planting!

Mulching trees

Thu, 08/08/2019 - 6:46pm

Mulching a newly planted tree is a must.  What does mulching do?   Several very important things.  It helps retain moisture.  It keeps mower decks and weed whips away from the tender bark of a tree (one of the biggest causes of death in young trees) and it prevents competition from weeds and grass.  

A tree is an investment.  Whether you can afford a really large tree – or a more modest tree – to you it is an investment.  By properly mulching the tree, you are taking one step into the long term viability and success of your new tree.

Volcano mulching

I drove down one of the streets in Northfield where there was new commercial development taking place.  The developer had installed several boulevard trees and they had been “volcano” mulched.  A no-no in the mulching your tree world.  Volcano mulch is where the mulch is highest around the trunk of the tree – usually 4 to 5 inches up the trunk and goes down to the ground around the tree – kind of like making the tree the lava in this volcano example.  

Volcano mulching can seriously damage the bark of young trees.  That bark is super thin and when there is several inches of mulch around the base of the tree – it is the perfect habitat for insect development and mice to hide, and it holds moisture all around the trunk which could lead to rotting of the trunk.  

Proper mulching is where there is little to no mulch around the base of the tree and then tapering up to about 3″- 4″ high out to where you began to dig your hole.  This enables all rain and watering water to congregate right over the root ball of the tree which is so critical in the first few months in the life of a newly planted tree.  After the first year, you can level it off a little so it isn’t quite so pronounced.  

My picture here is of one of our trees that we have planted in our woods following the tornado so it is not the best picture – but it shows the bare trunk and the mulch coming out and up.  

We’ll be touching a little more on watering and winter protection for your trees in future blogs – but if you have “volcano” mulched your newly planted tree – re-do the mulching for the health of the tree.
