Culture NotesRose 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.

Planting and establishing shrubsThe 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.

The flowers are suitable for cut flowers.

EnvironmentThis plant tolerates drought.
This plant will grow in moist soil.
Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to neutral (less than 6.8 to 7.2) soil.

Leaf Color Green
Fall Color No change in fall color

This plant has attractive foliage.

Culture NotesHemerocallis hybrids come in a wide range of colors, flowering times and sizes, and some even come with a fragrance. For the most part, daylilies are long-lived, hardy perennials that are tolerant of the sun. However, some species will show sun scald and prefer partial sun. Daylilies are adaptable to a wide range of soil conditions, and most bloom from late June until the first frost (depending on the cultivar). These plants attract both butterflies and hummingbirds and, usually, are both heat and drought resistant. Hemerocallis are extremely tough plants that spread rapidly in most conditions, thereby choking out weeds without becoming invasive themselves. The best time to plant daylilies is early spring. Although the individual blooms are short-lived, the number of blooms you get from an average flower stalk continues on for weeks.

Daylilies adapt to almost any location that provides at least six hours of sunlight, but it's best to plant them in a prepared, raised bed of soil that is high in organic matter. For clay soil, coarse sand and organic matter should be mixed in. When planted, the crown should be even with the soil line. The growth rate of daylilies can be increased via generous irrigation practices. At the end of the flowering season, remove the spent flower stalks only so that the remaining dying foliage will protect the center of the plant through the colder winter months. Also, division of the plant every two or three years will increase stem strength and flower size.

'Black Eyed Stella' is an All American Daylily Selection. A heavy rebloomer, its ruffled flowers are golden yellow with a dark red eye.

Culture NotesLilac is a common flowering shrub that grows best in a sunny location. The plant will grow in shade but flowering is poor and powdery mildew is likely to be severe. The growth rate is rapid and the plant produces many suckers. Pollen bothers certain people.

Planting and establishing shrubsThe 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.

Spread 6' to 10' / 1.80m to 3.00m
Growth rate Average
Form Vase shaped
Exposure Partial shade or partial sun to full sun
Persistence Deciduous

Bloom Color White
Bloom Time Summer

The flowers are very showy, suitable for cut flowers and suitable for dried flowers.

EnvironmentThis plant tolerates some drought.
This plant will grow in dry soil.
Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to slightly alkaline (less than 6.8 to 7.7) soil.

Leaf Color Green
Fall Color Yellow

Culture NotesPanicle Hydrangea should be grown in full sun or partial shade on well-drained, moist, loamy soil. Plants flower best in sun. The upright, spreading branches often bend down with the weight of the blooms, and the brown, faded blooms should be removed in late September to keep the tree from looking unkempt. If unpruned some people object to the pinkish brown fruits and old flowers which hang on to the tree during the winter. Pruning also is suggested to keep the plant to a consistent, neat shape. Lower branches can be pruned to clean up the bottom of the plant and make it grow into a multi-stemmed tree. Flowers emerge white and turn pink.
This plant is considered mostly allergy free and causes little or no allergy problems in most people.

Planting and establishing shrubsThe 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.

Perennial Of The Day

Gazania rigens syn. Gazania ringens; Gazania splendens 'Daybreak Red Stripe'
Treasure Flower, Gazania


Type Perennial
Hardy range 7A to 9A
Height 6" to 12" / 15cm to 30cm
Growth rate Average
Form Upright or erect
Exposure Full sun

Bloom Color Red and yellow
Bloom Time Summer and Fall

The flowers are showy.


EnvironmentThis plant tolerates drought and salt well.
This plant will grow in dry to moist soil.
Suitable soil is sandy.
The pH preference is a neutral soil.

Leaf Color Green and silvery

Culture NotesThe well known garden plant Gazania splendens (or "rigens") originates in South Africa. The petals are usually orange, yellow or white, but sometimes bronze or pink. At the base they are often brown forming an attractive ring at the center. The flowers close in darker weather and opens again with the first rays of the sun. "Daybreak", called after this surprising effect of the sunlight, is one of the most well known Gazania hybrids.
'Daybreak Red Stripe' is a really unique variation of this Gazania series, with a red stripe dissipating out over each deep yellow petal. This gives the startling effect of a radiating sun when the flowers open.
It is the third Gazania from the 'Daybreak' series to win a Gold Medal from Fleuroselect, the international organization for testing new flower seeds. The golden-yellow 'Garden Sun' from 1990 was only emanated in 1996 by 'Bright Orange' which bloomed earlier, richer and more uniformly than any other seed Gazania. The new 'Daybreak Red Stripe' yet again beats its predecessors in beauty, keeping the compact form, and countless, large, single flowers, which open earlier than other Gazanias. This richly flowering and unusual plant therefore shines in the garden, even before the penetration of the first sun's rays.
If sown in January, 'Daybreak Red Stripe' can be planted out from May (end of the frosts). To germinate, the seeds should be covered lightly and kept damp at 21 ° C. After 3 weeks the seedlings can be transferred to 9 cm pots or sets (16 or 24). Growth regulators are not required. Hobby gardens can expect later flowering due to lower temperatures during the growth period. Gazanias perform well in borders, rockeries and in pots. They can withstand dry conditions, salty air and wind and have a preference for a sunny spot and well-drained soil.

Deciduous Tree Of The Day

Malus x 'Burgundy'
Crabapple, Flowering Crabapple

Type Tree, woody plant
Hardy range 4A to 8A

Spread 15' to 25' / 4.60m to 7.60m
Growth rate Average
Form Rounded and vase shaped
Exposure Full sun
Persistence Deciduous

Bloom Color Red
Bloom Time Spring

The flowers are fragrant and showy.

EnvironmentThis plant tolerates some drought and a little salt.
This plant will grow in dry soil.
Suitable soil is well-drained/loamy, sandy or clay.
The pH preference is an acidic to slightly alkaline (less than 6.8 to 7.7) soil.

Leaf Color Green
Fall Color Yellow

Culture NotesCrabapple is well-adapted to compacted urban soil, tolerates some drought and is somewhat tolerate of salt-spray. Well adapted to all areas within its hardiness zone range, including Texas and Oklahoma. Very adaptable tree. Do not over-fertilize, since this could increase the incidence of disease and will cause excess sprouting. Select only from disease-resistant cultivars avoiding 'Radiant' and other sensitive cultivars. Crabapples are not well suited for high pH soil, are best grown in a sunny location with good air circulation and have no particular soil preferences, except soil should be well-drained. Rooted pruned trees transplant most easily. This plant is considered mostly allergy free and causes little or no allergy problems in most people.

Maintain adequate mulch areaClear all turf away from beneath the branches and mulch to the drip line to reduce competition with turf and weeds. This will allow roots to become established quickly and keep plants healthier. Train and prune the trunks and branches so they will not touch each other. Remove some secondary branches on main branches with included bark, or those that are likely to develop it, as soon as possible. This reduces the likelihood of splitting from the tree later, when the tree has grown to become an important part of the landscape. Locate the tree properly, taking into account the ultimate size, since the tree looks best if it is not pruned to control size. The tree can enhance any landscape with its delightful spring flush of flowers. It can be the centerpiece of your landscape if properly located. Flowers develop from buds formed the previous year.

Tree establishment specificationsChoose good quality trees for planting. The most common cause of young tree failure is planting too deep. In most instances, the point where the top-most root in the root ball originates from the trunk (referred to as the root flare zone or root collar) should be located just above the soil surface. You may have to dig into the root ball to find the root flare. If there is nursery soil over this area, scrape it off. Never place ANY soil over the root ball. The planting hole should be at least twice the width of the root ball, preferably wider because roots grow best in loose soil. In all but exceptional circumstances where the soil is very poor, extensive research clearly shows that there is no need to incorporate any amendments into the backfill soil. Simply use the loosened soil that came out of the planting hole. Simply planting with the topmost portion of the root ball slightly higher than the surrounding soil might still install the tree too deep - be sure to locate the root flare.
Weed suppression during establishment is essential. Apply a 3-inch thick layer of mulch to at least a six-foot diameter circle around the tree. This area should be at least two feet in diameter for each inch of tree trunk diameter and maintained during the establishment period. Apply a thinner layer of mulch directly over the root ball but keep it at least 10 inches from the trunk. This allows rainwater, irrigation and air to easily enter the root ball and keeps the trunk dry. Placing mulch against the trunk and 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 after planting encourages rapid root growth that is essential for tree establishment. Trees provided with regular irrigation through the first growing season after transplanting require about 3 months (hardiness zones 9-11), 6 months (hardiness zones 7-8), or one year or more (hardiness zones 2-6) per inch of trunk diameter to fully establish roots in the landscape soil. Trees in desert climates may take longer to establish. Trees that are under-irrigated during this establishment period (and most trees are) often require additional time to establish because roots grow more slowly. Be prepared to irrigate through the entire establishment period, especially during periods of drought.
Irrigation also helps maintain and encourage the desirable dominant leader in the tree canopy on large-maturing trees. Instead of a dominant leader, trees that are under-irrigated during the establishment period often develop undesirable, low, co-dominant stems and double leaders that can split from the tree later.
Unlike established plants, which do best with deep, infrequent irrigation, research clearly shows that recently transplanted trees and shrubs establish quickest with light, frequent irrigation. For trees planted in spring or summer, provide one (cooler hardiness zones) to three irrigations (warmer hardiness zones) each week during the first few months after planting. Daily irrigation in the warmest hardiness zones provides the quickest establishment. Following the initial few months of frequent irrigation, provide weekly irrigation until plants are fully established. With every irrigation, apply one (cool climates) to two (warm climates) gallons of water per inch trunk diameter (e.g. 2 to 4 gallons for a 2-inch tree) over the root ball only. In most landscapes that receive more than 30 inches of rain or irrigation annually, if the mulch area is maintained weed-free, irrigation does not need to be applied outside of the root ball. Never add water if the root ball is saturated.
In cooler hardiness zones, in all but the driest years, irrigation of spring- and summer-planted trees usually can be discontinued once fall color has begun. Irrigation of fall planted trees, however, should be continued until foliage has dropped from the deciduous trees in the region. In warmer climates, irrigate fall-and winter-planted trees as described for the spring- and summer-planted trees.
In drier, desert climates there is benefit to be gained from applying additional irrigation outside of the root ball area. This is best done by making a large diameter berm four to six inches high, then filling it with water so it percolates into the soil. For the first two years, irrigate twice each week through the spring, once per week in summer provided monsoons arrive, and twice each week again in fall if it remains warm. Taper off watering to once or twice each month in winter and resume twice weekly next spring. For years three to five, water twice per month in spring, summer, and fall and once or twice per month in winter. During years five through seven, water once every three weeks in warm weather and once every six weeks in winter. After this, the drought-tolerant desert trees should be able to survive on natural rainfall.
Trees with good, strong structure need no pruning at planting, except to remove broken twigs. Do not remove branches to compensate for root loss - research has shown that this can be detrimental to establishment.
