Foxtail grasses grow annually, making their appearance in the first months of the year from January through April. They dry out by late spring, which is when they are the biggest threat to your pets. However, some of these pesky foxtail weeds are perennial and live for several seasons before dying out.

Don’t pick up dirt after aerating. Even though it's tempting because soil cores are incredibly unsightly, these cores and the dirt they leave behind are ecologically important. This is what keeps your grass looking beautiful and growing healthily. The soil cores need two to three weeks to decompose, but you can swat them with a rake if their natural shape bothers you.

If you want to take the decomposition process into your hands to speed it up, water and sunlight are key. Of course, you can’t control sunlight yourself, but you can rake leaves into piles in sunny spots in your yard. In terms of using water, you can also moisten the decomposing leaves with water, whether by pouring some from a watering can from time to time or using a hose to moisten them.

Many privet varieties are considered invasive, particularly in North America. They can grow quickly, spread into the wild, and push out native species if left uncontrolled. It’s a particular problem for warmer southern states, and some regions even have warnings or regulations against planting certain types of privet. You can reduce (but not eliminate) the chances of privet spreading by cutting its flowers in summer before they develop.
