How to Grow Mexican Sunflower Seeds
Growing Mexican sunflower seeds is a straightforward process, even for those new to gardening. Here’s a step-by-step guide:
1. Choose the Right Location
Mexican sunflowers thrive in full sunlight, so pick a spot in your garden that gets at least 6-8 hours of direct sunlight daily. The soil should be well-draining to prevent waterlogging.
2. Prepare the Soil
Loosen the soil and remove any weeds or debris. While Mexican sunflowers are not fussy about soil quality, adding compost or organic matter can improve growth.
3. Plant the Seeds
- Sow the seeds directly into the soil after the last frost.
- Plant them about 1/4 inch deep and space them 12-18 inches apart to allow room for growth.
4. Watering
Water the seeds lightly after planting. Once established, Mexican sunflowers are drought-tolerant and only need occasional watering.
5. Fertilising
These plants do not require heavy fertilisation. A light application of a balanced fertiliser can be used if the soil is poor.
6. Maintenance
- Remove weeds regularly to prevent competition for nutrients.
- Deadhead spent flowers to encourage more blooms.
