How to Take Care of Roses
Roses have a reputation for being difficult to care for, but with the correct amount of water and sunlight and a little bit of grooming, your roses should thrive. Explore these basics of caring for your roses — but if you forget or muff something, the plants are surprisingly forgiving:
Watering roses: The rule of thumb is to make sure roses get about 2 inches a week. Deep soakings are much better than frequent, shallow waterings. Set the hose at the foot of the rose and let water trickle in. Or if you have a big bed of roses or roses and companions, use a soaker hose or install an in-ground system.
Fertilizing roses: Use an all-purpose garden fertilizer, because it has balanced amounts of N (nitrogen), P (phosphorus), and K (potassium). Fertilizers touted especially for roses — such as Rose Food — are fine but not mandatory. In spring, as the plant emerges from dormancy, you can water with a tablespoon of Epsom salt (magnesium sulfate) dissolved in a gallon of water to promote strong canes.
Always water before applying fertilizer so the plant is plumped up and under no stress.
Grooming roses: Using sharp clippers, you can spruce up your rosebushes whenever something unattractive about the plant catches your critical eye.
Here’s stuff you can cut out any time you see it:
Dead wood: Remove dead canes down to the ground level.
Damaged wood: Cut it back into about 1 inch of healthy wood.
Misplaced stems: Take off stems that are rubbing together (choose one and spare the other), stems that are taking off in the wrong direction, and stems that are trailing on the ground.
Suckers: In a grafted plant, these errant canes emerge from below the graft union (the bulge at the base of the bush). The suckers look different from the rest of the bush — they’re often smoother, straighter, and lighter in color. Another clue: They sprout leaves and occasionally mongrel flowers that look nothing like the main bush.
Deadheading and tidying up roses: The plant looks better when you get rid of spent flowers. Also, because the goal of all flowering plants is to stop flowering and produce seed (in the case of rosebushes, to make rose hips), deadheading thwarts the process. So the plant is fooled into making more flowers. Deadhead away!
Whenever you see badly damaged, diseased, or dead leaves, remove them. To be on the safe side, throw them in the trash rather than in the compost pile. Otherwise, the leaves may spread disease.
Pruning roses: Early spring is the best time to prune. If it’s still winter, your overeager cuts may lead to frost damage. Pruning is pretty straightforward: Remove all non-negotiable growth, thin the plants, and then shape them.
Experts advise cutting 1/4 inch above a bud eye so the bud eye doesn’t dry out.

Use clean, sharp clippers, and cut at a 45-degree angle. Cut near a bud eye, the tiny brownish or reddish bump on the stem (not to be confused with a thorn).

Gardening Glossary
annuals
Plants that complete their entire life cycle within one growing season. The plant germinates from seed, grows and blooms, and then produces seed and dies.

Gardening Glossary
biennials
A plant that take two growing seasons to complete its life cycle. It germinates and grows leaves and stems in the first year; produces flowers and fruit (seed) in the second, and then dies.

Gardening Glossary
bolt
When a plant flowers or produces seed prematurely.

Gardening Glossary
cold frame
A wooden or concrete block box in which you can grow plants or hold dormant during the cold winter months.

Gardening Glossary
cole crops
A family of vegetables, including broccoli, cabbage, cauliflower, kale, and Brussels sprouts. They thrive in cooler weather.

Gardening Glossary
complete fertilizer
Any fertilizer that contains all three of the primary nutrients, N-P-K (nitrogen, phosphorus, potassium). Phrase is based on regulations governing the fertilizer industry. Does not mean that the fertilizer literally contains everything a plant needs to thrive.

Gardening Glossary
deadheading
The practice of pinching or cutting off spent flowers

Gardening Glossary
evaporative-pad humidifier
A humidifier in which fans blow across a moisture-laden pad that sits in a reservoir of water.

Gardening Glossary
harden off
The process of acclimating plants grown indoors gradually to the brighter light and cooler temperatures of the outside world.

Gardening Glossary
hardiness
The ability of a plant to survive is called its hardiness.

Gardening Glossary
humus
A stable end product of organic-matter decomposition that's believed to increase microbial activity in soil, improve soil structure, and enhance the root development of plants.

Gardening Glossary
Bacillus thuringiensis Bt
An effective bacteria that attacks only the larvae of caterpillar family insects. It is safe to other insects, animals, and humans.

Gardening Glossary
macronutrients
Mineral nutrients that plants need in the largest quantities: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.

Gardening Glossary
mulch
Organic or inorganic material placed over the surface of soil, usually directly over the root zone of growing plants. Used to conserve moisture, kill weed seedlings, modify soil temperature, provide attractive covering to garden beds.

Gardening Glossary
organic matter
Once-living stuff like compost, sawdust, animal manure, ground bark, grass clippings, and leaf mold (composted tree leaves). Used to enrich soil and improve soil texture.

Gardening Glossary
perennials
Any plant with a life cycle of three or more years. Herbaceous (non-woody) perennials include flowering plants and herbs, mainly. Woody perennials include trees and shrubs. Longevity depends on the plant and growing conditions.

Gardening Glossary
pH
The measure of soil's acidity. Soil with low pH means it's too acidic; soil with high pH means it's alkaline. Most plants grow best in soil with a pH value between 6.5 and 7.2. Neutral soils measure 7.

Gardening Glossary
photosynthesis
The process through which plants take nutrients from the air and from the water in the soil to produce sugars that fuels the plant's growth.

Gardening Glossary
primary nutrients
Nitrogen, phosphorous, and potassium are the three nutrients plants need in the largest quantities.

Gardening Glossary
root crops
Plants with edible underground roots such as onions, carrots, beets, potatoes, turnips. Most root crops are cold-weather crops.

Gardening Glossary
self-blanching
A type of cauliflower with leaves that naturally curl over the head and exclude light. Requires cool temperatures for leaves to curl effectively.

Gardening Glossary
sets
Small onion bulbs, about 1/2-inch wide, that were started from seed the previous year. Grow onion sets with the pointy end up.

Gardening Glossary
side-dressing
The act of adding a small amount of fertilizer around or "on the side" of plants after they're growing.

Gardening Glossary
succession planting
Planting small, 2-to-4-foot patches of plants every two weeks throughout the growing season so that you can harvest a crop over an extended period of time.

Gardening Glossary
thinning
The act of cutting the least robust seedlings in your garden to give the healthier plants more room to grow.

Gardening Glossary
vining crops
Crops that grow on vines, such as cucumbers, melons, pumpkins, and winter squash. They usually require support (staking, trellising, etc.) to keep them off the ground.
