Keeping a New England aster short can be achieved through regular pruning. This not only controls the height of the plant but also helps maintain its shape. There are a couple of approaches to achieve this, including pinching and cutting back.
Pinching asters, similar to mums, involves regularly removing small bits of new growth until the first of July. This method requires a bit more effort and attention, as you need to constantly monitor the growth of the plant and pinch off any new shoots that appear. By doing this, you are effectively limiting the upward growth of the aster and encouraging a more compact and bushy appearance.
However, if you prefer a simpler approach, cutting back the aster by half in mid-June can be a more convenient option. This involves pruning the plant by removing about half of its height. By doing so, you are essentially removing the top portion of the plant, which stimulates new growth and results in a more compact and shorter plant.
To carry out this method, you will need a sharp pair of pruning shears or secateurs. Start by assessing the height of the aster and determine where you would like it to be shortened. Ideally, you should make the cut just above a node or leaf junction to promote new growth. It’s important to make clean and precise cuts to avoid damaging the plant.
Personal Experience:
I have personally used both pinching and cutting back methods to keep my New England asters short and well-maintained. While pinching requires more attention and frequent maintenance, it can be a rewarding process as you witness the plant’s growth and shape being shaped over time. On the other hand, cutting back in mid-June has been my preferred method, as it provides a more immediate result and requires less ongoing effort.
Regardless of the method chosen, it’s important to keep in mind that asters are resilient plants and can withstand pruning. They respond well to being cut back and tend to bounce back with vigor, producing more flowers and maintaining a healthier appearance. Regular pruning also helps prevent the aster from becoming leggy or top-heavy, ensuring a more aesthetically pleasing and well-balanced plant.
In summary, to keep a New England aster short, you can either pinch the new growth regularly until July or cut back the plant by half in mid-June. Both methods effectively control the height and shape of the aster, promoting a more compact and bushy appearance. Choose the method that suits your preference and gardening style, and enjoy the beautiful and well-maintained aster in your garden.
