This is the time of year when leaves are turning shades of yellow and red and falling from the trees. And this spurs homeowners to get out there with their rakes and rid them from their lawns. This is a good practice as too many leaves will shade out the grass and decrease the quality of the lawn come next spring. So, go ahead and rake them up. However, think about using as many as you can as mulch in other parts of your yard.

Leaves can be placed as mulch in landscape beds “as is” or chopped up with your mower or shredder into finer pieces and then spread around perennials, shrubs and trees. When chopped up or shredded, they tend to stay in place much better and don’t blow around when it gets windy. As the leaves break down over time, their nutrients are released and become available; that’s free fertilizer for your landscape plants. Leaves as mulch do have a natural look in the landscape, so if you prefer a more formal or polished look, you can spread a thin one-inch layer of a commercial mulch over the leaves.
Organic mulches (those made from plants) offer many benefits. They add organic matter and improve soil fertility as they decompose, thus reducing the need for added fertilizers. Mulch helps to maintain soil moisture so less frequent irrigation may be needed. Soil-borne disease can also be prevented as the soil does not splash up on the bottom leaves of plants during periods of rain. One of the favored reasons to use mulch is to prevent weeds in your landscape beds. And, of course, mulch is much prettier to look at than bare ground!
So how deep should you apply mulch? University of Florida experts advise a 3 to 4 inch layer of mulch around shrubs and trees. However, keep mulch from setting against the stems and trunks as that can cause moisture and pests to adversely affect them. Place just a thin one-inch layer of mulch over the rootballs of your plants.
Using leaves as mulch recycles a natural resource and saves you money, enriches your soil, fertilizes your plants and keeps them out of the local landfill.

Here’s a beautiful native perennial wildflower that is easy to grow and generally available in the independent nursery trade. In the wild, you can encounter them at the edges of woodlands and ponds as they prefer moist areas. Blue mistflower, Conoclinium coelestinum, performs well as a perennial in the home landscape but does spread easily by seed and will spread in the garden. It also spreads through underground rhizomes which allow it to form large clumps. This is an advantage for the informal garden, however, the gardener who prefers a more formal look will have a bit more maintenance in controlling that spread.
The abundant flowers look like bluish-purple puffballs on the top of the stems. The color is unusual and adds a striking touch in the garden. The bloom season is mid-summer to mid-fall. Butterflies are frequent visitors, making this an excellent addition to your butterfly garden.
Blue mistflower has a full rounded form and will grow to 3 feet under optimum conditions. Leaves are opposite and have a triangular shape. Growth and blooming is best in full sun to part sun conditions.
Give it a try!

This autumn you may notice shrubs with long, arching branches sporting clusters of shiny purple berries. That beautiful sight is the Beautyberry, or Callicarpa americana. This native is found throughout Florida and the southern United States, west into Texas and north to Tennessee and Virginia.

In the spring, lavender flowers adorn the branches and are a favorite of bees. The flowers eventually give way to the shiny purple berries in the fall. Birds find the berries very attractive and will feast on them when found. Mockingbirds and cardinals are especially fond of them. If you plant this shrub for the birds, one or two plants will provide more than enough of the berries to satisfy their appetites.
Beautyberry is adaptable to a wide variety of soils and moisture. After it gets established it is drought tolerant, however it can also do well in a moist area. A spot in your garden that gets partial sun is a perfect location. Plants in too much sun sometimes get a bit yellow and those in too much shade get leggy and don’t set as much fruit. Beautyberry is deciduous, meaning that it will lose all its leaves in the winter. Therefore, you may want to place it in an area of your yard where it won’t be a focal point in the winter.
This lovely plant is usually readily available at independent nurseries. If you prefer to grow your own, beautyberry is easy to propagate and grows rapidly. Snip off an approximate 6-inch piece from the end of a stem; the cut piece should have 5 sets of leaves. Snip off the bottom 2 sets of leaves – this part of the stem will be in the soil and roots will emerge from where the leaves were removed. Also snip off the top of the stem to include the top set of leaves. Your cutting will end up with only 2 sets of leaves. Immediately put the cutting in a good potting soil, making sure that the lower part of the stem where the 2 sets of leaves were removed is below the soil line. Keep the soil moist as the cutting develops a good root system.
You and the birds will enjoy this lovely shrub for years to come!

In the midst of your September strolls through natural Florida, you may come across this native beauty, the narrowleaf sunflower, Helianthus angustifolius. Another common name is swamp sunflower. I found this gorgeous patch in the photo close to the shore of Apalachicola Bay. It occurs throughout Florida and north throughout much of the eastern United States. Florida is fortunate to be home to over 20 native species of sunflower.

This perennial starts blooming in late summer and dazzles admirers throughout autumn. The 2 to 3 inch flowers with bright yellow petals and brown centers are attractive to butterflies and other pollinators. What a great addition to your butterfly garden!
Plants generally grow to about 2 foot tall but they can grow a bit leggy to 6 foot. If desired, keep them more compact through pruning in late spring. Clumps can be divided every few years to spread them out or to share with friends and neighbors.
Like all sunflowers, it loves full sun but can tolerate some light shade. Narrowleaf sunflower is salt and flood tolerant and will do well in most soil types, however it does best in consistently moist conditions.
Narrowleaf sunflower plants may be difficult to find in the nursery trade but they can be readily started from seed.

Many of us have a tendency to want to spoil those we care for – our significant other, our pets, our children, even our lawns. Some homeowners who long to have a lush, green, healthy lawn tend to spoil their lawns with lots of water. Their lawns should not suffer through a dry, thirsty day! However, spoiling a lawn with too much water can literally be killing it with kindness. (Keep in mind that we are discussing established turf, not newly installed lawns; new lawns do need special care.)
Turfgrass that is overwatered can suffer several fates. Roots can stay shallow near the surface and not dig deep into the soil as they should. A deep root system allows the turf to be more resistant to stress from drought, disease and abiotic factors such as wear from traffic. Excessive water leads to excessive lush growth – that may sound like a good thing, but it’s not. Excessive lush growth leads to thatch build-up and it creates a perfect environment for pests and diseases. An abundance of water also assists those nasty weed seeds to germinate and compete with your turfgrass.
So how do you know how much irrigation is best for the health of your lawn? That depends on the temperature, time of year, the type of turf and your soil type. Irrigate just enough to get water to the root zone without leaching beond that zone. Usually, that amount is 1/2″ to 3/4″ of water each time you irrigate. How often, then, do you turn on those sprinklers?
Let your lawn get thirsty before you water. University of Florida research shows that lawns that dry out and start to show a little drought stress before getting more water actually perform better in the long run. So wait until the leaf blades start to fold, the blades start to look a bit off-color, or you can start to see footprints where you’ve walked.
