Range of Sage
Sage needs full sun and grows best in poor well-drained somewhat dry soil, which makes it fairly drought resistant. You can propagate sage by seed, cuttings and the layering.
Overwatering can cause serious mildew problems. Cut back the stems after blooming. If you cut frequently to harvest leaves be sure to fertilize plants occasionally with a well-balanced fertilizer. You can grow new plants of most species from seeds. Grow garden sage and pineapple sage from low layers and stem cuttings. Renew plants by dividing every 3 to 4 years
As culinary sage is a plant that thrives in dry limestone areas in poor well drained soil, though it can be grown almost anywhere if the climate is not too cold and wet for it. Propagation is usually buy cuttings, often rooted by layering. Although the plant is a perennial it becomes woody and straggly, so it’s best to layer and replant every few years. One or two brushes will suffice for the average garden. Sage leaves dry well and are suitable for quick freezing. As with many leafy herbs the best flavors develop just before flowering. Wash the plants in your garden with a very fine spray of water and let it dry overnight. In the morning cut the stems at ground level and hang bunches of stems in a dark and dry area. Strip the leaves from the stems and seal them in airtight containers in a dark pantry.
