Canna


QUICK REFERENCE PLANTING GUIDE

1. Light/Sun Exposure - Full to partial sun.

2. USDA Hardiness Zones - Not winter hardy. The Cannova Collection is hardy in zones 7-10 in-ground. Zones 3-6 must dig up and store for winter.

 

3. Planting Distance - At least 18 inches apart in-ground.

 

4. Mature Height/Spread - 30 to 48 inches tall with a 14 to 20 inch spread.

5. Bloom Time - Midsummer to frost. 

6. Planting Instructions - As indicated below.

 

Bare-root tubers - Dig a hole slightly larger than the tuber.   Position the root so that the top of the tuber (where the old stem can be seen) will be at or between one and two inches below ground level. Fill in the hole with soil to the level of the buds, carefully packing soil around the root with your fingers, being careful not to damage the tender pink eyes.

 

Potted Plants - Dig a hole at least twice the size of the pot in which your plants are growing. Partially backfill the hole, remove your plant from its pot, and carefully position the root ball in the hole. The top of the root ball should be level with the soil surface. 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 deep. If it is, raise the plant gently and re-firm the soil.  Water thoroughly. 

GET THE MOST ENJOYMENT

Cannas are a Victorian class of tubers now very much en vogue for planting in the contemporary garden.  After having been scorned for decades, they are now the height of fashion.  Whether you're planting the standard cannas or the dwarfs, they will perform in any zone and start to bloom in the early summer. All varieties are bold big-flowered, easy to grow, and bring a touch of tropical excitement to any location. 

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 to 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 it 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 - Clip off dead or unsightly growth to maintain attractive form and shape.  Deadhead or remove flowers when blooms have faded, leaving as much foliage as possible.  As long as the foliage remains green it will gather sunlight and transmit energy into the root system for the following growing season.

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.

Winterizing - In ground plantings will go dormant in the ground only in zones 7 through 10.

In zones cooler than 7, zones 3-6, dig and store the tubers in peat moss in a location where the temperature stays around 40 degrees F.

Containerized plantings can be moved indoors to a cool spot (i.e., unheated garage, shed) in winter where the plants will go dormant in the container.  Water them lightly every 2 to 3 weeks as needed. 

If you keep the tubers dormant in pots, simply move the pots outdoors or replant your container outdoors as soon as all danger of frost is over for your planting zone.

 

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.
