  • Scrape off the outer shell of the seeds with the back of a knife. This allows moisture to penetrate the inside of the seed and improves the chances of germination.

Astragalus Care

It is easy to take care of the herb when you have the have gone through complex steps of starting the seeds. You can grow more than one astragalus seedling in the garden. However, make sure that the herb varieties are a foot apart and the bush species are at least 4.5 feet apart. The rest of the plant care is pretty straightforward.


You can plant the seeds in normal garden soil. Even clay soil is enough for this purpose. But if you want to transplant the herb or bush in the garden, you need to improve this heavy soil and loosen its texture. An easy way to do this is to add coarse sand or perlite to the soil. How much sand or perlite you need depends on the type of soil. But you know if the soil stays loose in your fist rather than compacting, you have the right texture.

The pH of the soil should be between 6.0 and 7.0. That is as close as possible to neutral or slightly acidic. You can use lime to increase the acidity of the soil.


Astragalus prefers moist soil for a hardy perennial plant. So your goal would be to keep the soil moist throughout the growing season. And since it prefers sandy soils, which do not hold water well, you need to water it once a day in spring and summer. This applies to warm areas where the summer sun is merciless and moisture dries up quickly.

As for the water supply, the herb needs the same amount of water as many other plants in your garden. Give him about an inch of water a week and increase it in the case of the small bush type. Don’t let the soil dry out as your herb has a low tolerance to drought. Always try to water the plant deep and aim for the roots. Avoid spraying the foliage or flowers with water, as this would cause fungal infections. Astragalus does not tolerate high humidity either, so you need to improve the air circulation around the plants.


Astragalus is a moderate fertilizer and the richer the soil, the greener the leaves and the lighter the leaves Blossoms. You can dress the herb aside with any type of homemade compost or aged manure. Chemical fertilizers tend to stress the plant from sudden spurts of growth, so I advise you to avoid them. However, if you are growing the plant for its foliage, use a nitrogen-rich fertilizer with a 10-5-5 label in moderate doses. For ornamental varieties you can also use fertilizers rich in phosphorus in the ratio 5-10-10 in small doses.

Use the fertilizer once a month. If the plant is not growing well, increase the dose and apply it every two weeks. Cover the beds with a 2-inch layer of mulch in the summer.This is more true of the bush species than the herb species. However, you will need to prune the plant regularly to keep it in good condition. The best time to prune this perennial is in the fall, when the flowers have faded and fallen off. Start by removing any damaged, broken, and tangled stems. In the case of bush varieties, cut off the idiosyncratic branches to maintain the shape of the bush. Also make breaks in the foliage to improve air circulation for the inner stems and branches. And if you don’t want the self-sowing plant to reproduce and reclaim every inch of the garden, core the flowers to keep the plant from producing seeds and becoming invasive.

Harvesting astragalus

Astragalus herb harvesting

You can harvest the roots of astragalus for culinary purposes once the plant is established. You should not harvest the roots too early as this could affect the growth of the plant. Most experts recommend that you start harvesting astragalus roots as soon as they reach the third year. This will give the root system enough time to fully develop.

To collect the roots, carefully cover the soil and harvest the tender roots closer to the surface. Do not harvest more than 30 percent of the root system at one time. Also, you shouldn’t use chemical fertilizers when you plan to harvest the roots. After harvesting, cover the roots with soil again, then fertilize with organic compost and water the plant.

As a piece of advice, don’t harvest the roots until about three weeks after the last fertilization. Do not harvest the roots immediately after fertilizing. They have an unconventional taste.

To use the harvested roots, place them in a bowl of warm water and keep them there for a day to remove unwanted odors. Then rinse well, cut into slices and place on a sheet of paper to dry. Keep the cut roots in a warm and dry place for up to three weeks. When they are completely dry, store them in a tightly closed jar. At normal room temperature they stay fresh for up to a year.
