6. Planting Instructions - As indicated below.

 

For container planting: Fill the container with soil to within 4 inches of the top. Dig a hole in soil to insert the lower part of the root ball.  Remove plastic containers and loosen up roots that have encircled the growing pot.  Place the plant in the hole and back fill to original soil line.  Water well and if necessary, adjust the plant so that it is upright. Add additional soil to bring level back up to original soil line. Never insert the plant lower than the original top of the soil ball.

For in-ground planting: Dig a hole twice as wide and twice as deep as the pot in which your plant was grown. Please note that many of our pots are biodegradable. If your plant is not in a traditional plastic pot then you may place the entire biodegradable pot in the ground; otherwise, 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. 

VARIETIES 

Tidal Wave® Petunias sport a unique habit that has earned it a new classification of petunia called ‘hedgiflora’.  Taller growing and spreading, they readily adapt to their space. If you like container planting, try planting this petunia in a container or hanging basket to create an elegant focal point.

Your Littletunias™, as implied by their name, are miniature petunias that literally cover in a canopy of color!  That is exactly what this garden series is all about. These new beauties flower early and are so tightly branched, they yield a proliferation of 1 inch long lasting flowers that blanket the compact trailing mounded plants that trail 1 ½ - 2 feet.

Supertunia:

'Double Peppermint' Petunia x hybrida: Double Petunias have always seemed to be more difficult to find, and one look at Peppermint and you can see why everyone buys them. Their flower form almost reminds you of a carnation, and the dramatic infusion of shell pink color onto the snow white petals is pleasing to the eye. Grows only 6" tall and spreads up to 24", loves full sun.

'Priscilla' Petunia: Profuse double white blooms with striking purple centers! The non-stop blooming nature, combined with the cascading effect will keep your containers and beds full of color all summer long. Reaches a height of 6 to 12 inches with a similar spread. Loves full sun!

'Dark Blue' Petunia: The Double Dark Blue has beautiful dark blue flowers. Supertunias are so aptly named for their extreme blooming 5 to 7 inches tall with 24 to 36 inch spread. Suggested as a Spiller in your container garden.

'Night Sky' Petunia: This beauty is dark violet with white spots and has a semi-trailing habit. They will flower earlier than most petunias and will look beautiful in a container or in the ground. The spotting pattern is random and the color patterns vary as the seasons and temperatures change. No need to dead head! 'Night Sky' will grow 10 to 16 inches tall with a 24 to 36 inch spread.

 

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 for Acid Loving Plants. 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 other 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 unsightly or dead growth to maintain good form and shape. Remove spent blossoms to promote additional blooming.

NOTE: The Tidal Wave® and the 'Night Sky' varieties naturally discards its spent blooms so there's no need to remove the dead blooms.

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 for Acid Loving Plants.

Winterizing - These plants are annuals and will not survive freezing temperatures.  They should be discarded at the end of the season.

 

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.
