Too hot to fertilize your Albuquerque lawn?
Before applying late-season fertilizer, check the label
Q: Early in the spring of this year we purchased one of those lawn fertilization programs at a big box store. Now we鈥檙e at the last bag, and the instructions are saying to apply it this time of year. The wife thinks it鈥檚 still too hot. I鈥檓 torn as to whether or not to apply the last bag as the instructions suggest. We鈥檝e had good results so far with the program鈥檚 guidance, but we don鈥檛 want to harm the lawn in the least. What do you think we should do? Apply the last bag for this growing season or wait? 鈥 L.G., Albuquerque
A: I鈥檓 sort of leaning toward your wife鈥檚 thoughts. It is still quite toasty, and if the program is following everything I remember about them, the last bag鈥檚 nitrogen level is probably quite high, meaning a bit on the hot side.
I鈥檓 going to suggest that you read the package labeling, top to bottom, to see if it lists any temperature restrictions for the application of the fertilizer. If it does, adhere to the suggestion. If the labeling doesn鈥檛 list temperature restrictions, perhaps there is a manufacturer/producer phone number that you could call for guidance. Applying a high or quick-release nitrogen content fertilizer when it鈥檚 hot could be very detrimental to the lawn.
Once you鈥檝e determined that you can apply the product, follow the application instructions to the letter. Does the label suggest mowing before application of the fertilizer? Does it suggest prewatering the lawn just before the fertilizer application? Does it caution you to water it in thoroughly after applying the fertilizer?
However, the label suggests you apply this last fertilization for the year, it鈥檒l be best to follow those rules religiously. If it were up to me, I鈥檇 be doing all I could to be sure any temperature restrictions were investigated first and foremost, then apply when you can safely, so that way the lawn won鈥檛 be shocked or maimed going into the autumn season.
Begin your investigation before you do anything to the lawn. Also, I really don鈥檛 think a high-nitrogen type of fertilizer should be applied to any of your trees, shrubs or roses this time of year. They should be aimed into a period of rest now, and offering a kick in the pants that a high nitrogen fertilizer would offer is not the ticket.
If you feel the need to fertilize trees, shrubs, roses and all your plantlife, while you鈥檙e out there fertilizing the lawn, find a high phosphorus content fertilizer that you could offer them. That way you鈥檇 be helping them with the food they鈥檇 use to maintain healthy roots and create even more roots during the dormant season.
It鈥檇 be a win-win for all the landscaping. Nitrogen for the lawn, phosphorus for everything else.
Happy Diggin鈥 In, after you鈥檝e gotten all of the info you need to keep the lawn happy and healthy!
