Clematis 'Sweet Autumn'


QUICK REFERENCE PLANTING GUIDE

1. Light/Sun Exposure - Full sun to partial shade with added shade to root system.

2. USDA Hardiness Zones - 5 to 9.

3. Planting Distance - 4 to 6 feet apart in ground.

4. Mature Height/Spread - 15 to 30 feet tall with a similar spread within 2 years. Can be pruned as needed for size and shape.

5. Bloom Time - Early fall.

6. Planting Instructions - Dig a hole twice as wide and twice as deep as the pot in which your plant was grown. Gently remove the root ball from the pot. Partially backfill the hole with soil and place the plant into the hole. The top of the root ball should be level with the ground surrounding the hole. Refill the hole with soil, firming the soil around the plant with your fingers. Check to be sure that the plant is not planted too deeply. If it is, raise the plant carefully and refirm the soil. Water thoroughly.

GET THE MOST ENJOYMENT

‘Sweet Autumn’ is a vigorous climber with small white flowers that completely cover the plant while it is in full bloom. Like its name implies, it blooms during fall and adds grace and fragrance to your trellis or pergola.

SOIL PREPARATION

Although these plants will perform well in average garden soils of all types, we recommend having your soil tested periodically by the local County Extension Office.  These tests can determine if the soil needs any amendments to enhance your plants' growth and performance.  See below for our recommended practice to improve your soil without any additional testing:

1.  Spade or till the soil to a depth of 12-18 inches.

2. To provide nutrients and improve drainage, add organic matter to your soil by mixing in a 2-4 inch layer of dehydrated manure, garden compost, shredded leaves, and/or peat moss.

3.  After active growth begins, periodically feed with Cottage Farms' water soluble Carefree Bud-N-Flower Booster. Plants in containers need more frequent watering and feeding, especially when in active growth and bloom.

CONTINUING CARE

Water - Your plants require 1" of rainfall (or equivalent watering) each week when planted in the ground.  Do not allow plants in containers to dry out.  In a container that is exposed to full sun, water well at least once every other day, and possibly every day, during periods of intense summer heat.  You may wish to temporarily move containerized plants to an area where they are shielded from the hot summer sun (i.e., in the shade of a tree, on a porch near an overhang).

Mulching - Apply a 2-4 inch layer of shredded bark, compost or other organic mulch around your plants to promote moisture retention, maintain even soil temperatures, and to discourage weed growth.

Weeding - Keep the area around your plants free of weeds. Weeds compete with all plants for food, water and light. Walk around the garden periodically and pull weeds, including the roots, as soon as you see them.

Grooming - ‘Sweet Autumn’ flowers on new growth and should be pruned each year to encourage prolific growth and blooming. Cut each plant down to about 12 inches in early spring while it is still dormant. You may also clip off unsightly or dead growth throughout the season to maintain good form and shape.

Feeding - Feed your plants once every 2-3 weeks during the growing season with a water-soluble fertilizer such as Cottage Farms' Carefree Bud-N-Flower Booster. Discontinue feeding after September 1st so your plants can harden off for winter dormancy. Resume fertilizing when new growth appears in the spring.

Winterizing - The time to protect your plants in the garden is after the ground has frozen. At that time, apply a winter mulch of evergreen boughs, straws or leaves to prevent lifting of the plant's roots during alternating periods of freezing and thawing.

For container planting, move plants next to your home's southern foundation for added warmth and protection. They may also be moved into an unheated, protected area such as a garage or cellar. If moved to a protected area be sure you water them well once every 7 to 10 days.

In spring, remove mulch from in-ground plantings and remove any dead or damaged parts on any plants.  Also, bring containerized plants back out into the garden sunlight where they will immediately begin to repeat their yearly garden performance.  

 

CAUTION: Not all plant material is edible. Though most plants are harmless, some contain toxic substances which can cause headaches, nausea, dizziness, or other discomforts. As a general rule, only known food products should be eaten. In case of ingestion, please contact your local poison control center at once and advise them of the plant ingested. Keep out of reach of children.
