Clematis ...
Spring Is A Great Time
To Plant Clematis.

With nearly 300 species and countless cultivars, there's no doubt why they are called the:

"Queen of Climbers"

Vining plants with large, showy flowers. Some so breathtaking you would consider the flowers fake.

 

NEW! Clematis This Season:

Coming Spring 2011

Clematis That Grow In SHADE:

Despite rumor, some varieties of Clematis will grow in shade.

Alabast — Cream Green Clair de Lune Silver Moon
   
Viticella Venosa Violacea    

Clematis Are Easy To Grow

Location/Site
  • Sunny tops, cool roots
  • Pick a site that receives half-day or full-day sun. A little afternoon shade may help keep the deep-colored flowers from fading.

Support

  • Provide support for vining. Clematis climb with twining leaf petioles, so small wire, fencing, nylon netting, or string can be added to the trellis.

Soil Conditions

Having the right soil is critical if you want to succeed with Clematis. 

This plant adores:

  • A rich, organic soil that is heavily amended with compost.  Clay soils is not recommended. Hot sandy soils will not allow the vine to grow to its full potential.
  • Keep moist, but well drained.
  • Mulch to keep the root zone cool

Pruning Types

PRUNE TYPE (1) This group of Clematis produce their flowers directly from OLD stems and, therefore, pruning must not be done until right after all flowereing has been completed. Prune this group by removing al;l dead and weak stems immediately after flowering. Large established plants over 15 feet are not normally pruned, especially if they are growing in trees. All stems at this time should be tied in position on their trellis or other host. Also, if the Clematis has outgrown its space, the correct and only time to prune to size is right after floweering is done. After pruning, new growth will begin, this brings the stems for next years flowers.

PRUNE TYPE (2) In this group, all first flowering comes from last season's ripened stems. In the early spring watch for swelling leaf buds beginning to show. Cut all dead material off above these swelling buds. Be sure all growth is tied to the trellis at this time. Do not tie too tightly, so growth can begin and not be hampered by tying to toght or cracking the stems.

PRUNE TYPE (3) this group blooms later and from NEW growth. This group should be pruned in early spring as new buds begin to show low on the plant. All dead material above these buds should be removed at this time. Clean out any old foilage that has mildew at this time also.

Which Clematis Varieties need which Pruning Type?

Feeding

Clematis are heavy feeders. Use compost every spring with several shovels full being applied around the base of each plant. When the new vines are two to three inches long, give them a boost of fish food emulsion.

Replenish soil each spring with compost. When new vines are 2" - 3" long, give them a boost with a fish emulsion fertilizer

NOTE: Feeding with a high nitrogen fertilizer may reduce bloom production in favor of more vegetative growth.

PRUNING For Max Bloom

Macrophylla Hydrangea do not need to be pruned back unless they are more than 5 years old. Removing dead stems is the only pruning needed for plant health.

  • Dead blooms can be removed at any time.
  • After the plants fifth birthday about 1/3 of the older living stems should be removed to the ground each summer.
  • June & July are the best months to trim.

As a rule these type of hydrangea set buds for next years blooms during August & September. Ever Blooming and Endless Summer are exceptions to the rule.

Piniculata & Arborescens Hydrangea are fun because they can be pruned at almost any time.

To be safe do not trim in the spring;

  • Annabelle
  • Summer or Pee Gee, when they are preparing to bloom.
  • They are determined and will bloom every single year no mater how they are treated.

Drying Hydrangea Blooms

The secret is to not cut them at the height of their color. Fresh, recently opened blooms rarely dry well. Harvest during Sept. thru Oct. after the blooms take on a vintage look. Remove leaves, air dry.

Zone 4 Winter Protection For Macrophylla

The macrophylla Hydrangea are at the northern limits of their capabilities here
in the Twin Cities.

To maximize the summer bloom

  • Do not trim after July
  • After the first hard freeze wire cage and cover the entire plant branches with marsh hay or leaves

ABOUT ZONE HARDINESS ...
When planning your garden you need to take planting zones and frost dates into consideration. In Minnetonka we are a Zone 4.

See the planting Zone Map as a general reference when determining what garden and landscape plants will survive our climate area.

Plant Hardiness Zones divide the United States into 11 planting zones based on a 10 degree Fahrenheit difference in the average annual minimum temperatures.

For example, the average annual minimum temperature in Zone 2 is -50 to -40 degrees Fahrenheit, and the average annual minimum lowest temperature in zone 10 is +30 to +40 degrees Fahrenheit.

There are also different climates and frost dates within planting zones in a region due to the topography, lakes and rivers, canyons or mountains. These can cause altered airflows which can raise or lower the temperature, changing the zone in your area. The chemical balance and texture of the soil, exposure, altitude, rainfall, humidity, sun light levels, and wind, and wind chill factors can also alter the effects of plant hardiness zones.

11 Tips On Dividing Perennials

1. Divide When A Plant Looks Good

Don’t wait until a plant has become decrepit or monstrous to divide it. When plants still look their best, divide at the end of that growing season or after it’s bloom time.

Watch for the early signs that it’s time to divide: the center of the plant has smaller leaves, fewer flowers, and weaker blooming stalks, or the plant runs out of growing room on and has nowhere else to go.

2. Dig A Trench

To lift a perennial with minimal root damage, begin digging at its drip line. Dig a trench around the clump, cleanly severing any roots, then cut at an angle down and under the clump from various points around the outer edge until you can lever the plant out of the hole.

In early spring, divide while the new growth is still low to the ground. In summer, tie stems together before lifting the plant to avoid damage. In fall, cut plants back before digging them up for division.

3. Divide In Cool Weather

Perennials can be divided at any time of the year if you give the plant appropriate care. Divide when the soil is warm and the air is cool. The best times are just before peak daffodil season in spring; and in early fall after the nights become cool. These conditions allow the roots of the division to grow while the tops stay low, out of the sun and wind.

4. Keep Roots Cool and Moist

Put divisions into a bucket or box in a cool shaded place, such as a garage. Cover them with moist newspaper to reduce moisture loss. If, despite your best efforts, the divisions dry out while on hold, don’t despair. Soak them in a bucket of water for about an hour before replanting.

5. Replenish Soil With Organic Matter

New divisions need the advantage of renewed, fertile and well drained soil.

6. Use Vigorous Sections First

After dividing, replant pieces that are, at most, 20 to 25 percent of the original clump. Smaller sections grow more vigorously and tend to produce stronger, longer-lasting blooms.

7. Take Extra Care When A Plant’s In Bloom

Plants in bloom may not be capable of growing as many new roots as quickly as non-blooming plants. Given the extra care that common sense dictates (such as more attentive watering or shade at midday), these plants will fare well, too.

8. Keep Only The Healthiest Pieces

If you wait until a perennial is declining, has a dead center, or has succumbed to pest problems, be sure to replant only the healthiest pieces. Usually these are the outside sections. Watch for discolored stems and eroded crowns and roots.

9. Spread Out Your Divisions

Place a division into a hole that is twice the size of the root-ball. Spread the roots nicely throughout the hole. Be careful not to crowd or cram. During the next growing season, the top of the plant will grow as wide as the roots are at the time of planting. Ensure that when you spread out the roots they don’t overlap and compete with the other divisions.

10. Let The Roots Be Your Guide

When you dig up a perennial, you will see that it will fit one of five basic root types: roots that form clumps or offsets, surface roots, underground running roots, taproots, or woody roots. How you proceed depends on what root type your plant has.

Offsets

To divide a plant whose roots form offsets (small plants growing at the base of a larger one), snap the connection between any of the sections to obtain a piece with ample roots and three or more growing points or “eyes”. Denser clumps may have to be cut apart.

Plants that form offsets include:

  • Asters
  • Coneflowers (Echinacea )
  • Hostas
  • Tickseeds (Coreopsis)

Surface Roots

Some perennials have roots that run on or just below the surface of the soil. They form new crowns and roots when they reach open spaces or make contact with the soil. If you cut between any of the stems, you will have a division with its own stems and roots.

Plants with surface roots include:

  • Bee Balms (Monarda)
  • Black-eyed Susan (Rudbeckia)
  • Creeping Sedums (Sedum spp.)
  • Creeping Speedwells (Veronica spp.)

Taproots

Plants that have taproots can be divided by using a sharp knife to slice down the length of the root. Every piece that has at least one eye, some of the taproot, and a few side roots is a viable division.

Plants that have taproots include: 

  • Balloon Flowers (Platycodon)
  • Butterfly Weeds (Asclepias)
  • Cushion Spurges (Euphorbia)
  • Oriental poppies (Papaver orientale).

Underground Running Roots

Underground running roots can develop suckers as they grow beyond the shade of the mother clump. These suckers can be cut away from the main plant.

Plants with underground running roots include: 

  • Hardy Geraniums (Geranium spp.)
  • Japanese Anemones (Anemone)
  • Ostrich Fern (Matteuccia )
  • Plume Poppies (Macleaya spp.)

Woody Roots

Woody perennials often form roots when stems rest on the ground or are buried by gradually accumulating mulch. Make a new plant by simply cutting between the rooted stem and the mother plant.

Plants that have woody roots include:

  • Candytufts (Iberis)
  • Euonymus (Euonymus)
  • Sages (Salvia spp.)

11. Water Your Divisions In Thoroughly

Watering is essential to establishing healthy divisions. Soak with a hose immediately after transplant and make special watering arrangements whether you are dividing in early spring or fall. Divisions will need more water than well established perennials to make it through the heat of the summer, and ample water before the first frost.

Timing Is Important

When dividing perennials, timing and technique are important. While many perennials can be divided in either early spring or early fall, some are very picky.

The optimal time to divide specific perennials is denoted by:

  • Divide In Spring
  • Divide In Early fall
  • Division should take place after the plant’s bloom time.
  • Wear Protective Gloves when dividing the plant, its sap may irritate skin.

Japanese beetles ...

By some estimates, the Japanese Beetle is the most devastating pest in the urban landscape. They can turn a beautiful garden landscape into a nightmare overnight. You may have recently noticed an influx of this pest. It was introduced to the United States from its native Japan in 1916. Without a natural predator, it has increased in population and has become a serious pest in the Midwest.

However, There Is Hope…
