If you have waited all summer to begin planting, you may wonder if it will simply be a waste of your time. Most crops are planted during the spring, yet it is still possible to plant certain vegetables that will grow in the late summer. In this article, Summit Turf Services gives tips on the best plants to grow for August gardening. Of course, the soil that you are using must be appropriate for the seeds. Additionally, you need to also water more extensively during the late summer because of the heat. However, if you are thinking about growing flowers and shrubs in late August in Missouri, the following plants will do very well during this time if you have properly prepared your soil.

How To Prepare Your Soil for August Gardening

Even though the following flowers and shrubs will grow in late summer, you do need to go through some minimal preparatory work. For example, you need to till the soil, allowing it to aerate. Tilling the soil will also ensure the water to percolate down. Many of these will have very deep roots. Therefore, it will be difficult to overwater if the soil is not too dense. It is highly recommended that you add some type of fertilizer prior to planting. At the very least, add nitrogen to the soil to get the best results.
