Thymus sipyleus Care
Thymus sipyleus
This thyme species, named after Mount Spil and endemic to Turkey, loves full sun and poor, gravelly, well-drained soils. It is exceptionally drought tolerant and, with its intensely aromatic leaves, is an excellent ground cover for rock gardens and dry areas.
Monthly care calendar
Timings are for a temperate Northern Hemisphere climate. In warmer areas tasks start earlier, in colder areas later; in the Southern Hemisphere shift them by six months.
- Watering: Not required; the plant is dormant and winter rains are sufficient.
- General care: The biggest risk in winter is excessively wet soil, so excellent drainage is vital.
- Pests & diseases: Care must be taken against root rot.
- Pruning: Light pruning can be done to remove branches damaged in winter. Wait for the main pruning/harvest.
- General care: The plant is preparing to wake up.
- Watering: Usually not needed. Only if newly planted and the spring is very dry, water 1-2 times a month.
- General care: New aromatic shoots appear. It can be propagated by division.
- Pruning: Not done; wait for it to flower. For culinary use, it can be harvested just before it blooms.
- General care: Flowering begins.
- Pruning: After flowering ends, it can be pruned lightly to keep the plant more compact and prevent it from becoming woody.
- General care: Drainage is vital for this plant. In heavy, water-retaining soil, plant on a mound or bed raised 20-30 cm, and keep the root collar above the surrounding soil level.
- Pests & diseases: Avoid watering to prevent root rot.
- Watering: In a long drought, water deeply once a month.
- Pruning: If not yet pruned, light trimming can be done.
- General care: It can be propagated by semi-hardwood cuttings in early summer.
- Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. Water the area around the roots to a depth of 15-20 cm.
- Pruning: Prune as soon as flowering ends. Next year's flower buds form over the summer; late pruning reduces flowering.
- General care: The plant may be semi-dormant during the hottest part of summer; this is normal.
- Watering: In midsummer, deep watering every 15-20 days is enough. Established plants (over 2 years old) do not need watering in most years. Water the area around the roots to a depth of 15-20 cm.
- General care: With the autumn rains it may produce new shoots.
- Watering: In a long drought, water deeply once a month.
- Fertilizing: Absolutely do not fertilize; it loves poor soils.
- Pruning: Pruning is usually not required this month. If it was not pruned after summer flowering and looks untidy, it may be lightly tidied up.
- Plant protection: Not needed; it is very resistant to pests.
- General care: The ideal time for planting new seedlings or for propagation by dividing existing plants.
- Pests & diseases: The only risk is root rot, which poor drainage combined with autumn rains can cause.
- Watering: Not required; autumn rains are sufficient.
- General care: The suitable period for new plantings continues. The plant prepares for winter.
- Pests & diseases: Make sure the soil does not stay wet all the time.
- General care: In winter rains, make sure water does not pool in the root zone; for this plant, drainage is more critical than irrigation.
- General care: Evergreen leaves continue to lose water in winter. Water thoroughly once before the soil freezes.
- Pests & diseases: Protect from standing water and waterlogged soil.
