It’s a good idea to wait a few days or a few weeks after the last predicted frost date. Weather is unpredictable and there’s always a chance the forecast could be wrong.
Tests vary in terms of use. Usually, you insert the test in the soil for a set period of time, sort of like using a thermometer, and then check the test to see the pH.
Limestone is your best option to raise pH levels. Limestone should be added to the top seven inches of your soil. To lower pH levels, opt for acidic materials such as pine needles and peat moss. If you need to lower your soil’s pH fast, opt for sulfur. If you don’t want to alter your soil’s pH, plant your zinnias in a pot or raised gardening bed with potting soil that has the right pH level.
For example, if you planned to plant and there was an unexpected rainfall, some sand can be used to improve conditions. However, in the event of a very heavy rainfall, you may want to wait a few days to plant. The soil will be very wet and adding sand may not be enough to dry it out.
It’s a good idea to bring a measuring tape to ensure proper spacing rather than estimating on your own.
Review your fertilizer’s package for precise instructions on use. The package should indicate how much fertilizer should be used depending on the size of your garden.
