Roses – Flowers that Start with R

Roses do the best in well-drained, fertile soil with a pH between 6.0 and 6.5. Mulching with compost will add more nutrients to the soil besides maintaining soil structure. Besides, the addition of compost can be done in the autumn and springtime since this is the best way to add nutrient-rich matter to the soil. In addition, roses like deep watering with water provided at the base of the plant. This encourages deep root growth and reduces the chance of fungal diseases on the leaves.

It is part of the essential work on rose bushes to give them a well-pruned appearance and enough food to ensure that they bring forth what is expected of them: healthy growth and abundant bloom. The best time to prune roses is in early spring, just as new growth begins. Remove any dead or diseased wood and cut back the remaining stems to shape the plant and encourage new growth. Deadheading spent flowers throughout the growing season also helps to stimulate continuous blooming.

Ranunculus

Brightly colored with multilayered petals, ranunculus flowers are defined by horticulturists. Available in red, yellow, pink, and orange, ranunculus blooms are spring annuals, gaining great popularity for wedding bouquets and flower arrangements. They like full sun with well-drained soil.

Planting Ranunculus tubers should be installed with great care so that their establishment is good. Soak the tubers in water some hours before planting. This eases their rehydration, and they sprout more quickly. There should be well-drained soils to plant the tubers at a depth of about 2 inches, and the distance between them should be 4 to 6 inches wide apart. The “claws” of the tuber must be facing downward.

The Ranunculus plants require adequate moisture but do not like excessive waterlogging. Water them regularly, especially during dry periods, but allow the soil to dry slightly in between waterings to prevent root rot. Leaves are known to help give a better environment for growing due to their ability to retain moisture in the soil and reduce weed growth.

Rhododendron – Flowers that Start with R

Rhododendrons are large, evergreen shrubs with cluster bell-shaped flowers that come in pink, purple, red, and white within the same species. Rhododendrons additionally require acidic dirt. These bushes broadcast a somewhat tropical feel, perhaps emulating the jungle.

The secret on how to grow healthy rhododendrons is the provision of appropriate soil conditions. Rhododendrons thrive well in acidic soils, preferring well-drained conditions with a pH of 4.5 to 6.0. For those with a naturally higher pH than that, you can add peat moss or some other organic matter to it to bring it down. And of course, make sure the site has good drainage, as waterlogged conditions will promote root rot.

Rhododendrons require the careful management of a fine line when it comes to watering. They need to stay evenly moist, but at the same time, overwatering can also render them vulnerable to root rot. Water the plants thoroughly but less frequently. Water more so during dry spells, but be sure the soil is somehow dry before the next wetting. Keeping organic mulch applied around its base helps retain moisture to maintain the coolness of its roots.

Rudbeckia

Also known as Black-eyed Susans, Rudbeckias are yellow and dark-centered cheerful flowers. They are annual or perennial plants that bloom beginning from late summer to fall. The daisies are easy to grow; they require full sun and well-drained soil. The flowers are also drought-tolerant.

Rudbeckias will perform well in almost any kind of soil, so long as it is free-draining. The best place is considered sunny—no less than six hours of direct sun daily. Plant Rudbeckias with a spacing distance between 12–18 inches, allowing a good passage of air, thus no spread of the disease.

Some of the advantages of growing Rudbeckias include drought tolerance once established. The plants tolerate dry conditions excellently and can be great for low maintenance. Still, consistent watering during the first growing season helps to establish a strong root system. Deadheading can encourage repeated flowering while prolonging the flowering period.

Most importantly, the site should be well-drained to avoid root rot. Russian sage should be planted in full sun with at least six hours of direct sunlight.

Once established, Russian Sage plants are extremely drought-tolerant. Water regularly during the first growing season to establish a strong root system. After the first year, deep water occasionally allows natural rainfall to suffice. Pruning the plants back in early spring helps to maintain their shape and encourage new growth.

Occur invasive a minimum of six hours a day, Rue grows in sites with direct sunlight. It is deer resistant as it can fend off other growing conditions indicative of most domesticated species.

Rue plants are rather low on maintenance after the phase of getting well rooted. The first growing season entails regular watering to enable the plant to develop a proper root system. Consequently, the plants will be able to withstand a lack of moisture quite well and will need very little watering. The plants may be pruned back after flowering to promote new growth and maintain shape.

Red Hot Poker – Flowers that Start with R

Commonly known as red hot poker or torch lily, Kniphofia is a pretty perennial with tall spikes of tubular-shaped flowers in shades from red through orange to yellow.

Once established, Red Hot Pokers are fairly drought tolerant and will need little if any water at all. Water moderately through the initial growing season to establish a well-developed root system. Cutting the plants back after blooming to encourage new growth and keep them in shape may help.

Rhodora

This deciduous shrub sports bright pink or purple flowers in early spring. It does best in well-drained acidic soil and partial shade. Rhodora is often found in bogs and wetlands and adds color to natural landscapes.

Growing Rhodora is best in soil that is between 4.5 and 6.0 on the pH scale. Though Rhodora normally grows in acidic soil, it acclimates incredibly well if put into soil heavy on clay in pH. Add peat moss or other organic matter to the landscape to lower the pH. This shrub should be situated in a part sun area, as too much direct sunlight scalds it.

The Rhodora plants require constant moisture, especially during extended periods of drought. Water them quite regularly to keep the soil moist but not waterlogged all the time. Mulching around where the roots are, but a little distance away from them, will also help in retaining moisture for longer while keeping the roots cool. Pruning the plant after flowering will need to give the plant a good shape and commemorate the new shoots or branches’ growth.

Rhubarb is among the hard perennial vegetables whose green leafstalks have a tart flavor. Large green leaves at the top and clusters of small, greenish-white flowers that bloom from late spring through early summer characterize it. Rhubarb grows best in well-drained, rich soil and full sun to partial shade.

Rhubarb enjoys cultivation under full sun combined with fine well-drained soil. These plants thrive best in rich, fertile soil with a pH of 6.0 to 6.8. Sow the crowns of rhubarb in early spring or fall, allowing the crowns 3-4 feet space between them so there is room for good air circulation around them.

Rhubarb needs a sufficient amount of moisture for proper growth. Water it regularly to keep the soil moist but not waterlogged at all times during growth. Mulching around the plants will help retain moisture and control weeds. Harvest stalks that are firm and at least 12 inches long, but in moderate amounts at a single-cut period to let it keep growing.
