February
Ajuga – Making sure your Ajuga is in the right place in your yard - Locate ajuga in either sun or partial shade in well-drained soil. While these sturdy plants will tolerate soil that is quite acid and low in nutrients, they prefer only slightly acid soil (pH 6.0 to 6.5) that has some organic matter mixed into it. Soil must drain well, however, because ajuga is prone to rots and fungal diseases that are fostered by soggy soil.
March
Ajuga – In the first few years of building an Ajuga bed, sprinkle a handful or two of slow-acting granular fertilizer on the soil around Ajugas in the spring if their soil is poor. Do NOT allow it to settle on the leaves. This will supply a season's nutrition for these plants. Once they are well established, Ajugas do not need routine supplemental feeding.
April
Ajuga – Plant seedlings or divisions in either spring or fall. Transplant containerized nursery stock anytime during the growing season. Choose an overcast day or plant in the evening so that the transplant is not stressed by the sun while it copes with transplant shock. Locate Ajuga in either sun or partial shade in well-drained soil. While these sturdy plants will tolerate soil that is quite acid and low in nutrients, they prefer only slightly acid soil (pH 6.0 to 6.5) that has some organic matter mixed into it. Soil must drain well, however, because ajuga is prone to rots and fungal diseases that are fostered by soggy soil. Spacing the plants 6 to 8 inches apart, dig holes roughly 3 to 4 inches deep and 6 inches wide.
May
Ajuga – Ajuga will bloom in May and sometimes into June. By removing flower stalks after bloom, you prevent reseeding and improve their appearance. This deadheading also encourages a possible second flowering later in the season. This plant is great in yards owned by folks with allergies. It has no pollen that causes any allergenic effect. (for more information see Tom Ogren’s Allergy-Free Gardening available at Amazon.com)
Optional - After bloom time, you can rejuvenate large plantings by mowing them at your lawnmower's highest blade setting or using a string trimmer to cut them down to 4 or 5 inches.
June
Ajuga - Encourage sparsely-growing spots to fill in by pinching off the stem tips.
Similar to many fellow members of the mint family,
ajuga is sometimes invasive, enthusiastically taking over whole garden beds and sneaking into the lawn. The lawn can be protected by some kind of lawn edging material that prevents the Ajuga stolens from moving into the lawn.
July
Ajuga – Ajuga will need watering whenever rainfall is scarce, especially if their soil is not healthy and lacks enough humus to hold moisture. Try not to let their soil dry out totally for long
August
Ajuga – Plant seedlings or divisions in either spring or fall. Transplant containerized nursery stock anytime during the growing season. Choose an overcast day or plant in the evening so that the transplant is not stressed by the sun while it copes with transplant shock.
September
Ajuga - Pruning normally isn't required for Ajuga, although it may be necessary to clip off new plants that are formed from the spreading runners if they grow beyond their allotted space. Thin out Ajuga plants when their bed becomes overcrowded.
October
Ajuga – Thin out ajuga plants when their bed becomes overcrowded.
