In Arizona, we face a variety of seasonal issues. At Silver Fern Landscaping, we are prepared to help you with those issues. See below for information about the most common seasonal issues, and when it's best to do seasonal work.
Frosts & Colder Weather:
Most plants can handle cold weather & mild frosts. Some will turn brown, but will come back and flourish in the spring (e.g. lantana, bouganvillea, orange jubilees, canna lilies). Others will get "frostbite" so they will be partly brown and will not regenerate quickly, however they rarely die (e.g. ficus trees, boxwoods). A few may die - primarily tropical or newly established plants. Most people just allow their shrubs to brown and have them trimmed back in the spring - so you don't need to do anything special unless you have sensitive plants or there will be a severe frost in the low 20's or below (in a severe frost you should definitely try to cover your plants with a sheet, bag, or tarp overnight). Because many plants are brown & look dead in the winter, but are actually only dormant, we recommend waiting until mid-March to decide if a plant should be removed. Deciduous trees will also lose all or some of their leaves - again, don't panic, that's completely normal.
Monsoon season in Arizona is June 15 to September 30. It is still very, very hot - but you can also expect strong winds, lightning, some heavy rain, and an occasional haboob (dust storm). We recommend trimming any trees with a dense canopy that might be blown over and any that are touching your house - especially desert trees like mesquite, palo verde, and acacia. You should consider changing the battery on your timeclock to keep the programmed settings if the power goes out.
Weeds pop up all year, but especially after it rains. We recommend pre-emergent weed spray to reduce new weeds germinating in your rock before the rainy seasons (so in June and December). Bermuda grass isn't affected by pre-emergent, so if it's growing in your rock areas it will need to be sprayed more frequently. Please contact our office if you would like a quote for pre-emergent spray.
Bermuda is the grass that can survive Arizona summers - however, it goes dormant in the winter (note, it doesn't die unless you completely stop watering it). Those who wish to have green grass during the winter will have their lawn overseeded with a winter rye blend. The overseeding process begins in September. In the spring, the rye will die off and the bermuda will come back through. Please note: you must be a biweekly maintenance customer in order to do overseeding. Please contact our office by mid-September if you would like to overseed.
We recommend fertilizing all plants & trees in April and September. We also recommend an additional fertilizing of citrus & queen palms in February (so 3 times per year). Grass should be fertilized in April and August - plus, if overseeding, in October and January.
Seasonal Plant Health:
If you'd like to plant something new, we recommend planting either in spring (March, April) or fall (October, November). These are when new plants tend to have the easiest time adjusting to their new home.
We recommend doing aggressive cut backs to reduce the size of a plant in the spring. This is great for sages, and will help them grow back nice and full. We also recommend stumping Mexican (red) birds of paradise in December.
