Olive herb – cultivation and care

Location

The olive herb needs a warm and sunny location. In addition to herbal beds and herbal spirals, sunny areas in the flowerbed are also well suited for the herbs. In addition, it is a pretty bed frame and fragrant structure plant between dry stone walls.

Soil

According to its natural range, the olive oil should be planted on rather nutrient-poor, calcareous and permeable soils. Ideally is a location next to rosemary, sage and lavender in the upper region or in the normal zone of a herbal spiral or in the rock garden. If necessary, you can loosen up the soil beforehand with some sand or gravel.

Cultivation

The sowing of olive herb should take place between March and beginning of April. The plant is one of the cold germs and needs for germination temperatures between 4 and 8 ° C / 39 and 46 ° F. The seeds can be sprinkled directly into the field under favorable weather conditions. Cheaper and more promising, however, is sowing in trays. The seeds of the herb are considered light germs. Therefore, the seeds are only lightly pressed onto the seed substrate. Good growing substrate are mainly mineral substrates with a small amount of potting soil.

Propagation

The best way to increase olive herb over cuttings in the spring: cut off in the early summer about 20 cm (8 in) long shoot tips, remove the foliage in the lower area and put the cuttings in sandy and nutrient poor potting soil. Keep the cuttings constantly moist until they are rooted and avoid waterlogging. After about two weeks, the seedlings should have formed roots. Then they can be individually transplanted in larger pots. The young plants should only be set outdoors after the last frosts.

Watering

Olive herb requires relatively little water. On warm and hot days it is recommended to pour with little water. Once every ten days, a little more water can be given, but only moderate amounts. Too much water can quickly lead to root rot and eventually to the death of the herb.

Fertilization

In the field, little fertilizer should be given to the olive in spring and after flowering. Optimal are organic fertilizers such as compost or fertilizer pellets. Although pure nitrogen fertilizers such as horn shavings can be used, phosphorus and potassium are also needed to a limited extent, so that occasionally a fully-fledged fertilizer should be administered. Excessive fertilization should be avoided.

Harvesting

If the plant is to be cultivated over a longer period, olive herb should only be harvested in small quantities. In the first year, it makes sense to pick off only individual parts per plant.

Store and preserve

Olive herb can be dried or frozen.

Dry olive herb

To dry, the cut branches are bundled and hung upside down in a warm, shady and airy place. The dried leaves are easily stripped off the stem and placed in an airtight container.

Freeze olive herb

For freezing, the portioning in ice cube container has proven. To do this, the leaves are brushed off the stems and distributed into the compartments of an ice cube container. Now fill the compartments with water and place the container in the freezer. Thus, you always have olive herb ice cubes at hand, which can be used in the kitchen.

Pruning

Oive herb needs a regular pruning, otherwise it will become bare after a few years. In addition, pruning stimulates the plant to a vigorous growth. In the pruning of thicker shoots slightly inclined cuts are to create, on these runs the rain better. Thus, no moisture forms in the subshrub and harmful mold can be avoided. The following procedure is to be followed when pruning:

  • Complete pruning only in early spring, just before the start of the growth phase
  • Cut to a maximum of one-third to half the stature height
  • Cut away already stalked flower stems completely
  • Completely cut back dead shoots near the ground
  • Pruning still-growing shoots only slightly
  • Always stop about 1 cm (0.4 in) above the new shoot
  • Pruning is also possible after flowering
  • Never cut into the old wood
  • Too deep cuts lead to the death of the plant

Wintering

The herb is conditional frost tolerant and should be wintered in the house or conservatory if possible. If transport of the plants from the field is not possible, brushwood and leaves should be placed around the plant, in order to avoid deeper frost damages.

Buy olive herb – What is there to pay attention to?

In many plant centers, hardware stores and weekly markets fresh olive plants can be bought. The plants themselves are relatively resistant to pests, so that diseases rarely occur. Before buying, however, take a look at the planter. Is the olive herb in too wet soil, one should back away from purchasing. Here there is an increased risk that the roots have been damaged and the herb can be hardly repotted. The price per plant is about 3 EUR/$.

Seeds for olive herb are unlike fresh plants hardly found in specialty stores. You will occasionally find what you are looking for on online marketplaces. Here, the botanical name (Santolina virens or Santolina rosmarinifolia) should necessarily be compared, as occasionally the gray holy herb is sold as olive herb. Although this has a similar healing effect, but not the intense taste of olives flavor. The price per package is about 2 EUR/$.

  1. Should I be concerned if the tips are wilting? I bought my Santolina rosmarinifolia from a nursery, and repotted it immediately. Currently misting lightly everyday in a shaded spot to acclimatize cos I live in the tropics.

    • Are all the tips wilting? Maybe you should place it in a warm, sunny place. Do not use too nutrient-rich soil.

      If it is not getting better, you can cut all the branches down to just above the wooden parts, it will grow again. Or, if there are still good, healthy looking twigs, you could cut off some at about 10 cm and just replant them in soil. They should root and grow.

      Hope that helps, and please let us know if it works.

  2. We kept 1 of ours in the greenhouse over the winter and watered it very sparingly: it died. The other we left growing in our rockery near sheffield UK and it is thriving. Our garden is part of a former sand quarry so it is very sandy.
