Small Garden Tips

Plant These Heat Tolerant Flowers Now to Bloom Through Fall

These gorgeous flowers can bloom from summer all the way through the first frost. Depending on where you live, that could be well into October!

Any of these fall blooming perennials can be grown in containers or small gardens.

Some grow tall enough to make colorful cut flowers you can display indoors too.

When you’re planting in containers, keep in mind container plants dry out faster than if they’re planted in the ground. you plant into plastic pots or containers, these hold moisture longer than a clay pot does.

Throughout the hotter days of summer make sure you water frequently. Testing the top inch or so of soil will tell you if its dry and your flower needs water. Don’t be afraid to soak the soil well at least once a week.

If you’re using a hose or watering can, water the soil not the leaves. Try to keep water from leaves if possible as wet leaves may burn if your plant’s in full sun. In a shaded area, wet leaves can lead to disease or pests.

Some flowering plants may be drought tolerant and can handle soil drying out a little, but don’t leave them in full sun or drying wind too long without watering.

Most of these are perennials, meaning they bloom year after year if they are cold tolerant to your climate zone.
