Culture Notes
Rose is the national flower. Depending on the cultivar, the growing attributes of roses vary widely.  Check with your nursery as to the specific attributes and growing requirements for your particular rose.

The rose is an essential garden element and will prosper if proper fertilizing, pruning and spraying are done on a regular basis. Planting as bare root plants in the spring or early summer is recommended, as it will not disturb the growth cycle. Roses need to be actively growing in order to flower. Place in the open in a well-drained soil where they receive plenty of sun light. Plant roses far enough apart so you can prune and treat for insect and disease problems adequately. If you can choose a spot with a soil pH around 6.5, this is ideal.

A 2-3 inch deep cover of mulch is needed to keep the soil cool in the summer, retain moisture and keep the plant warm in the winter months. Plant in full or partial sun; morning sun is best. Soil should be rich in organic material such as peat moss, rotted manure, leaf mold or compost. Allow adequate spacing between plants for better air circulation and to lessen the spread of disease.  Do not plant near tree roots as they can deprive the plant of necessary moisture and nutrients.

Winter protection depends on the climate and the location of the garden. In most locations that receive freezing temperatures, stop fertilizing in mid to late summer so the plant slows down its growth before the first freeze. After the first few cold snaps below freezing, mound soil to about 12 inches up the stems and cut back any canes greater than about 3 to 4 feet long. Some people tie the stems together to keep them from whipping around in the wind. You may also cover the soil mound with mulch to help maintain a constant temperature all winter long. This is not necessary in the warmest portion of the hardiness range. Roses may be propagated by root cuttings, budding, or grafting.

This plant is considered mostly allergy free and causes little or no allergy problems in most people.

Planting and establishing shrubs

The most common cause of young plant failure is planting too deep.  Plant the root ball no deeper than it was in the nursery.  In most instances, the root flare zone (point where the top-most root in the root ball originates from the trunk) should be located just above the landscape soil surface. Sometimes plants come from the nursery with soil over the root flare. If there is soil over this area, scrape it off.  The planting hole should be at least twice the width of the root ball, preferably wider.  In all but exceptional circumstances where the soil is very poor, there is no need to incorporate anything into the backfill soil except the loosened soil that came out of the planting hole.  Never place ANY soil over the root ball. If a row or grouping of plants is to be installed, excavating or loosening the soil in the entire bed and incorporating organic matter enhances root growth and establishment rate.

Weed suppression during establishment is essential.  Apply a 3-inch thick layer of mulch around the plant to help control weed growth.  Keep it at least 10 inches from the trunk.  If you apply it over the root ball, apply only a one or two inch layer.   This allows rainwater and air to easily enter the root ball and keeps the trunk dry.  Placing mulch against the trunk or applying too thick a layer above the root ball can kill the plant by oxygen starvation, death of bark, stem and root diseases, prevention of hardening off for winter, vole and other rodent damage to the trunk, keeping soil too wet, or repelling water.  Regular irrigation through the first growing season after planting encourages rapid root growth, which is essential for quick plant establishment.

Rock Soapwort: Featured Plant of The Day


 Saponaria ocymoides 
Rock Soapwort


Type    Perennial
Hardy range    2A to 7A
Height    8" to 12" / 20cm to 30cm
Growth rate    Fast
Form    Prostrate and spreading or horizontal
Exposure    Partial shade or partial sun to full sun
Persistence    Evergreen

Bloom Color    Pink

Environment
This plant tolerates some drought.
This plant will grow in moist soil.
Suitable soil is well-drained/loamy or sandy.
The pH preference is  a neutral soil.


Leaf Color    Green

Culture Notes
This is basically an evergreen plant with reddish stems that forms a dense mat.  It's a good choice for planting in the front of a border or as an edging plant.  Cut back after blooming to keep its shape and encourage new growth.  Although primary blooming occurs in the spring, sporadic flowering occurs until the fall months.  Root division can be done in the spring.  Seeds can be gathered in the summer.  In the spring, remove dead foliage only and shear lightly.

Foersters Blue Long-Leaf Speedwell: Featured Plant of The Day

Veronica longifolia 'Foersters Blue'
    Long-Leaf Speedwell

Type    Perennial
Hardy range    4A to 8A
Height    12" to 24" / 30cm to 60cm
Spread    18" to 24" / 45cm to 60cm
Growth rate    Average

The flowers are suitable for cut flowers.

Environment
This plant will grow in moist soil.
Suitable soil is well-drained/loamy.
The pH preference is  a neutral soil.

Leaf Color    Green
This plant has attractive foliage.

Culture Notes
Division of the clump can be done in the spring and stem cuttings can be taken in the summer.  Seeds can be sown after collecting them in the late spring.  Deadheading spent flowers may encourage a longer blooming period.  This hardy and easy to grow plant prefers the sun and a well-drained soil that does not dry out.  The flowers are long-blooming and arranged on long erect spikes.  The plant may need staking for support.
