How to Promote Plant Growth

By S.F. Heron ; Updated September 21, 2017

All plants require certain key ingredients to successfully grow and thrive in any environment. Proper sunlight, water, good soil, the correct temperature and nutrients promote plant growth. Location also plays a role in plant health, since crowded plants tend to experience stunted growth due to lack of circulation. Meeting these basic needs forms the matrix for how to promote plant growth for indoor and outdoor plants. Each plant purchased at the nursery comes with a label or tab describing everything the plant needs to thrive. Following a routine, and some additional tips, will produce success with your plantings and will promote constant plant growth.

Provide a healthy environment for the plant to grow and thrive. Soil should be rich with nutrients from additives such as peat moss and compost. These products break down tough clay soil, encourage drainage and provide essential nutrients for the roots of all plants growing in the garden.

Meet the lighting requirements for each individual plant. Never place a shade loving plant in full sun and don't place a full-sun plant in the shade. Sunlight needs are crucial to proper root, foliage and flower development. Read the label provided from the grower in each plant pot if you're unsure of the plants lighting requirements.

Provide plenty of room for the plant to reach mature growth with plenty of air circulation around the plant. Crowded gardens don't produce abundant flowers, foliage and a healthy root system since everything in the garden competes for limited resources in the soil.

Protect tender plants from adverse temperatures. All plants have temperature tolerances and extremes can damage foliage quickly. Protect plants from frost by covering with newspaper or light sheets. Apply a 3 to 4 inch layer of mulch to the garden bed to keep soil temperature even during the summer and winter months.

Water regularly to promote plant growth. Use a deep-watering technique to target the root area of the plant where the plant absorbs water. Spraying the leaves or flowers doesn't do much good for the plant and can invite the formation of molds on leaves and flowers.

Allow plenty of time for a plant to grow. The process of acclimating to a new location, spreading roots and subsequent foliage and flower growth takes time. This process can only happen at the plant's speed.

Fertilize based on the plants individual needs. Don't overload the fertilizer just to promote faster growth since this could damage foliage and kill the plant. Add fertilizer in a water-soluble form to allow the plant to quickly absorb nutrients through the root system.
