Summer Herb Planting Information

Starting your summer herb garden means choosing between transplants and seeds, with timing being essential for success.

Transplants give you a head start in the heat, while seeds offer more variety and cost savings if planted at the right time, considering the importance of timing.

Growing From Transplants Vs. Seeds

When choosing between transplants and seeds for your summer herb garden, you’re weighing convenience against cost. This decision shapes your entire growing season’s success.

Transplant Advantages shine through immediate results and reliability. Nursery transplants skip the 4-12 week germination wait, delivering established plants ready for summer heat. They’re perfect when you need herbs quickly or lack patience for seed challenges. However, these benefits come with higher costs—one transplant often equals dozens of seeds price-wise.

Seeds offer remarkable value with broader variety access. Most packets cost $2-$4 for numerous plants, while transplants run $3-$8 each. Seeds also develop deeper root systems without transplant shock, creating better drought resilience. Starting herbs from seed is also a cost-effective method compared to buying individual plants.

Germination Rates vary dramatically—basil seeds sprout reliably, while rosemary often fails. Maturity Times from seeds add weeks to harvest, but soil temperatures above 70°F improve success rates substantially.

Herbs Best Grown From Transplants

When you’re growing herbs in summer heat, transplants offer immediate results compared to seeds.

Rosemary transplants, thyme, sage, and lavender give you a significant head start with their established root systems.

Choose healthy, sturdy plants from reputable nurseries, checking for rootbound conditions.

Avoid rootbound prevention by selecting plants with white, fibrous roots rather than circling brown ones.

Hardening transplants helps them adjust to outdoor conditions.

Place them in filtered sunlight for a week before full sun exposure.

Plant during cool morning hours to minimize transplant shock.

Starting indoors isn’t necessary since nursery transplants are already conditioned for outdoor growing.

Water thoroughly after planting and provide light shade for the first few days.

This approach delivers vibrant, productive herbs faster than seed-starting methods.

Herbs Best Grown From Seeds

While transplants offer instant gratification, some herbs actually prefer the seed-starting route in your summer herb garden.

These varieties develop stronger root systems and better heat tolerance when you grow them from scratch.

Direct sowing herbs like cilantro and dill works best since they hate root disturbance. You’ll want to plant these seeds directly where they’ll grow.

For other heat-tolerant herbs, indoor seed starting methods give you better germination temperature control – basil seeds love warmth around 70-75°F.

Remember seedling hardening off before transplanting your indoor-started herbs outdoors.
