Frequently Asked Questions (FAQs)
1. Can I plant flower from seed in summer?
Summer is the perfect time to start off biennials and perennials, as well as some hardy annuals to flower in late summer and early autumn, when a lot of half-hardy bedding plants are past their best. There are natural advantages to sowing seed in summer, too.
2. What is the easiest summer flower to grow?
Marigolds. Cheerful marigolds are easy to grow in sunny spots, brightening your garden with shades of yellow, red and gold as they bloom all summer long. African or American type marigolds grow 3 to 5 feet tall, but you can find shorter and more compact varieties.
