| growth arrest | High temperature dormancy or malnutrition | Provide proper shade and supplement with diluted fertilizers |
| Base atrophy | Lack of water or damaged roots | Adjust watering frequency and check root condition |
3. Summer care tips
1.Temperature control:The suitable growth temperature for cactus is 20-35℃. When the temperature exceeds 38°C, cooling measures should be considered, such as moving to a cool place or using a sunshade net.
2.Watering tips:It is best to water in the early morning or evening in summer. The water temperature should be close to the ambient temperature to avoid cold water irritating the root system. When watering, water thoroughly until water flows from the bottom of the pot.
3.Time to repot:Unless necessary, repotting is not recommended in summer. If it is necessary to change the pot, it should be done in continuously cool weather. After changing the pot, place it in a cool and ventilated place to slow down the seedlings for 1-2 weeks.
4.Breeding method:Summer is the peak growth period for cactus lateral buds, and can be propagated by division. After cutting off the strong side buds, let the wound dry for 3-5 days before planting.
4. Differences in summer maintenance of different varieties of cactus
Different varieties of cacti have different adaptability to the summer environment:
| Variety type | Lighting requirements | Watering frequency | special needs |
|---|---|---|---|
| desert cactus | Needs plenty of sunlight | Once every 10-15 days | Extremely drought tolerant and afraid of moisture |
| Tropical cactus | Likes scattered light | Once every 5-7 days | Requires higher air humidity |
| alpine cactus | medium light | Once every 7-10 days | Afraid of high temperatures and needs good ventilation |
5. Summer cactus maintenance schedule
The following is a typical summer cactus maintenance schedule for reference:
| time | Maintenance content |
|---|---|
| 6-8 a.m. | Check plant status and water appropriately |
| 9-11 a.m. | Shade treatment (if necessary) |
| 3-5pm | Ventilation inspection, pest and disease observation |
| 6-8pm | Foliar spraying is possible (in areas with low humidity) |
| once a week | Rotate the flowerpot to ensure even light exposure |
| once a month | Fertilization (during vigorous growth period) |
Through the above maintenance methods, I believe your cactus can safely survive the hot summer and usher in a new growth period in autumn. Remember, observing the condition of your plants and adjusting maintenance methods in a timely manner is the key to success.
