Age Old Organics Fertilizers

We carry a range of Age Old Organics products in both liquid and dry (granular) forms with good history of success in Colorado gardens.

Organic LIQUID fertilizer concentrates which are diluted prior to use.

Age Old Bloom: 5-10-5 organic fertilizer concentrate that stimulates early growth, greater flowering and better fruit set. Use as a foliage spray or soil drench. It is odorless so can be used on house plants.

Age Old Calcium: Supplies plants with an effective source of calcium and helps correct calcium deficiencies in the soil.

Age Old CalMag2: Calcium and Magnesium fertilizer supplement designed to prevent and correct problems that can arise from deficiencies, such as blossom end rot in tomatoes.

Age Old Fish and Seaweed: 3-3-2 – a good quality fish emulsion with kelp. Loaded with macro nutrients, trace elements and bio-stimulants. It is effective to reduce plant stress and to stimulate root development

Age Old Grow: 12-6-6 fertilizer concentrate that stimulates vegetative growth. The higher nitrogen content enhances plant growth. Good for getting vegetables up to size before fruiting and for grasses and foliage plants. First use Grow, then switch to Bloom for flowering and fruiting.

Age Old Kelp: this seaweed concentrate is a very mild fertilizer, good as a foliage spray for small plants and for plants in stress and to use in the fall to help prevent frost damage. As a soil drench, it helps to restore biological life to depleted or poisoned soils. Mikl has used it for years.

Organic DRY fertilizers are slow release and long lasting. They are designed to build soil fertility and increase the soil life. These can worked into the soil at planting or used as a top dressing.

Age Old Fruit Finish: 2-10-20 with 1% Calcium. High phosphorus and potassium blend for enhancing the size and quality of flowers and fruits.

Age Old Grow: 8-4-1 with 1% Calcium High nitrogen to provide the soil with  sufficient organic nitrogen for bacterial conversion of soil microbes into usable forms.

Age Old In Full Bloom: 5-10-5 with 1 % Calcium. High phosphorus blend to increase flower formation. An excellent nutrient addition to potting mixes or soils as well as a top dressing on existing gardens and lawns.

Age Old Root Rally: 0-3-0 with 6% Calcium and Endo/Ecto Mycorrhizal inoculant. Provides mycorrhizal support for several types of trees, shrubs, flowers, fruits and vegetables. When applied to the plant’s root system, can help reduce transplant shock and lead to increased water and nutrients uptake
