The best time to prune rosemary is between March and June, when the warm weather and plentiful sunshine will help produce healthy new foliage. However, you can also begin as early as the last weeks of winter, or hold off until things start cooling off in the fall.  A good rule of thumb is to schedule your last trim of the season no later than 4-6 weeks before the earliest expected frost. This will give the new growth a chance to harden off before the temperature outside plummets. Get in the habit of pruning your rosemary around the same time every year. Regular attention will allow it to flourish. If necessary, purchase a new set of shears or have a well-worn older pair sharpened before you get started. The sharper the blades, the cleaner the cut, and the stronger the branches will grow back as a result.  Bypass pruners, which feature overlapping blades that move past one another as they close, tend to make cleaner cuts than traditional scissor-style shears.  The ragged cuts created by dull blades could leave your rosemary vulnerable to pests or infectious diseases. To prune large plants, start by snipping the spent flowers or gently pulling them off by hand. Focus on flowers that show signs of damage or are beginning to lose their color. Leave healthy blooms intact.  Mature rosemary shrubs put out delicate blue, pink, purple, or white blossoms which give them aesthetic as well as culinary value.  Rosemary flowers are actually edible, so consider saving a few of the blooms that appear to be in better shape. Cut stems that have been killed off by frost back to their first set of green leaves. Do the same for low-lying branches that show signs of fungal infection, such as drooping or discolored foliage. If the entire branch or stem appears to be affected, it's usually best to get rid of the whole thing to keep the condition from spreading. Spreading 1–2 inches (2.5–5.1 cm) of sand or pea gravel over the base of your rosemary plant can go a long way in preventing fungal diseases by helping the growing soil dry out faster. Use a pair of sharp pruning shears to clip the stems at a slight angle. Cleaning up the most developed offshoots stimulates new growth—sometimes, a single stem may even branch off into 2 separate stems when it grows back.  Avoid cutting below the lower leaves. Removing too much greenery can inadvertently harm the foliage, causing the plant to grow only bare woody branches.  Container-raised rosemary growing indoors should be pruned the same way. Keep the depth and angle of each cut consistent to give the plant a neat, well-manicured appearance. Try to avoid making it look too uniform, though. Rosemary is naturally bushy, so it’s okay for it to be a little thicker in some spots. You can also focus on one part of the plant for more practical pruning. If your rosemary shrub is overtaking a nearby plant or stretching out into a walkway, for instance, cutting back those sections will help open things up and create space.

Summary: Prune your rosemary in spring or early summer. Use a sharp pair of pruning shears. Remove dead or faded flowers. Do away with damaged or diseased shoots. Trim 2–3 inches (5.1–7.6 cm) from the outermost stems. Shape your rosemary as desired.


In order to write, you will either need staff paper and a writing implement, such as a pencil or pen, or some kind of music writing software. Writing by hand is problematic because, in order to hear what you’ve played, you have to be able to play an instrument or you need to find someone else who can. With music notation software, you’re able to hear what you’ve written immediately, using the computer playback.  Some examples of music writing software include: Sibelius First, Finale and MagicScore Maestro.  For free music writing software, try MuseScore and Lilypond. If you play or have access to an instrument, you can try playing your melodies using your instrument to hear how they sound before writing them down. Using the outline you created earlier, construct each individual movement. While writing, you’ll need to be constantly making decisions regarding different musical techniques and styles within your piece. Some of those techniques include:  Dynamics Rhythms Intervals Harmonies Theme development Counterpoint Voice leading Orchestration Traditionally, symphonies are written for the following instrumental types: strings (violin, viola, cello, and bass) woodwinds (2 flutes, 2 oboes, 2 clarinets, and 2 bassoons)  brass (2 French horn, 2 trumpets with a small orchestra) and percussion (2 tympani, triangle, and cymbal) for a small orchestra. A medium size is when you can add a piccolo, English horn, bass clarinet, contra bassoon to the woodwinds and double the number of French horns and add 3 trombone plus a tuba to the brass as well as extra percussion instruments. If you can go larger, go for it.  You don't however, have to stick with traditional instrumentation. If the instruments are available and there are players to play them, feel free to use other instruments in your symphony either adding them or using them like different colors (eg. replace one traditional instrument with one non-traditional one). For example, the inventor of the saxophone family designed his instruments for the orchestra (built in the keys of B♭ and E♭) as well as the military band. You could also include an instrument that's been revived like one of the recorders, the viola da gamba or the oboe da caccia for example. Some symphonies also have vocal accompaniment. Try giving the same melodies to different instruments at different times to create a motif within the piece.  Pay attention to layers and texture. There should never be any more than five layers happening at one time.
Summary: Gather your materials. Start writing. Assign melodies to different instruments.
