Fertilizers

Q. I know nothing about the various fertilizers for sale. What should I be aware of?

A. First a couple basic definitions. You will need to study and search for information on the following:

Photosynthesis - The process by which plants use the sun's light to produce food (carbohydrates).

Macronutrients - Nutrients required by plants for normal growth. Macronutrients such as nitrogen phosphorus and potassium are needed in large quantities by most plants.

Micronutrients - Nutrients required by plants for normal growth. Micronutrients such as iron zinc and manganese are needed in small quantities by most plants.

Annuals by definition are plants whose life cycle lasts only one year from seed to blooms to seed. Removing the flowers as they fade prolongs the blooming cycle but if left to produce seeds many annuals will readily reseed themselves. Annuals are usually available in little starter 'six packs' or in 4 inch 'color spots'. They are an excellent way to create a great splash of summer color in the garden or for long blooming annual baskets.

Perennials like old friends return year after year growing in size and stature until they reach their full maturity. Although they live on longer many perennials lose their vigor after 3-4 years and should be replaced. Most perennial plants may be divided to produce new plants or they may be grown from seeds or cuttings. Perennials are available as 4 inch starters or in gallon size or larger pots.

Optimum growth of turf flowers fruits and vegetables depends on many management factors one of which is ensuring a sufficient supply of plant nutrients.
