Is it too late to plant grass seed in June?
Generally speaking, June isn’t the best time to overseed your lawn. It is a little too late in the year for sowing grass seed and providing the best conditions for germination. The spring is ideal for this. That being said, you can seed a lawn in June, but you’ll need to put in extra work. August is an ideal time to plant seeds for a second gardening season that can be as productive as your major early spring plantings. Late summer is perfect for a delicious fall vegetable and herb harvest.June and July are also good times to start seeds for perennials and biennials to bloom next spring. I sow seeds in a protected seed bed and then transplant seedlings in fall to overwinter, then bloom, ensuring me a wonderful spring greeting in the garden next year.Cosmos germinate best in warm soil and don’t like having their roots disturbed, so June can be the perfect time to plant seeds. Pick a location with at least 6 hours of direct sunlight, and you should have flowers in 50 to 60 days. Once the seedlings are established, they don’t need continuously moist soil.June and July are also good times to start seeds for perennials and biennials to bloom next spring.

Can I plant tomato seeds in June?
Work from your final frost date to determine when to sow (mine’s late May-early June). Use my seed-starting calculator to get your start date (and a link to figure out your frost date if you don’t know it). Best Time to Plant Tomatoes Wait to purchase and plant your tomato transplants until after all risk of frost has passed AND nighttime air temperatures are reliably above at least 10C, ideally 15C. In my 5b garden this can be as late as mid-June.
Is June too late for sunflower seeds?
The best time to begin sowing sunflower seeds is in spring, between April and May. You can sow them as late as mid-June, but since they take 11–18 weeks to fully grow from seed, you won’t get flowers until autumn. So, it’s important to plan when you sow seeds based on when you want flowers. The best time to plant sunflower seeds is between April and May. You can sow sunflower seed as late as mid-June but bear in mind they take up to 18 weeks to flower from seed so they may not flower before autumn. Sow seeds individually in 10cm pots of peat-free, multi-purpose compost.Soaking them in water softens the hard seed coat, exposing the embryo to moisture and kickstarting growth. Sunflower seeds don’t need to be soaked before planting—after all, the seeds split easily—but soaking them for 12 to 24 hours will hasten germination and increase the number of seeds that sprout.
Will 20 year old seeds grow?
It is true that some seeds will germinate that are 17-20 years old, but how the seeds were stored has everything to do with viability length. I have had personally. Some, like onions and parsnips, are viable for only a year or two. Others, like squashes and tomatoes, last longer, for 5+ years. Here’s a handy chart showing estimates of seed viability from a few different sources. Amazingly, the longest-lasting seeds we know of are thousands of years old!
