As Penny Carnathan, Tampa Tribune Garden Writer - The Dirt, is fond of saying about one of her gardening friends. "Her thumbs are so green she can grow rocks".
Some folks rely mostly on organics. Why do they work so well for these green thumbs? Plant-soil-microbe-fungus relationships are highly complicated and studied but the truth is science has a hard time quantifying and isolating the tremendous number of complex interactions involved. We do know quite a bit about many interactions. We know that the good fungi and bacteria outnumber the bad many times over and when good fungi and good bacteria loose their overwhelming advantage things can go wrong. Compost and organic matter support good fungi good bacteria good nematodes and many other good microorganisms and earthworms with the good bacteria in their hyperactive gut. Too much salt based fertilizer upsets the balance and kills the good guys that are working in the organic system.
Compost and Organic Matter support the good micro organisms that naturally control bad nematodes. Most of the nematodes in the world are good guys. Nematodes account for 90% of the living multi-celled organisms on the planet yet you can't see them with the naked eye. They are really small but interrelated to the natural processes in more ways than we will ever know. So you have to take it on faith or experience that relying on organic processes will help turn your brown thumb green. Here is the scoop on Nematodes for Bedding Plants in Florida.
In contrast to gardening in soil rich in organic matter, we can grow plants in our nutrient poor sandy soils that have very little organic matter. This is where you need to add timed release salt based fertilizer. This is always more cost effective than liquid or fast release 6-6-6 granular that only seem cheap. Don't feed your plants a 3 month's supply of the cheap stuff only to have it wash away in one rain when you can give them a 3 month supply of timed release fertilizer in one application that releases a little with each irrigation. and not pollute the downstream environment!
Pot-in-Pot Landscaping is a great way to turn a brown thumb green. You should try this and report back on the color of your thumb. Ask away and we will answer questions to get you on the right garden path.
9 Principles of Florida Friendly Landscaping
We share through numerous posts our enthusiasm and experience as long-time Florida gardeners and horticulturists. Our hope is that your gardening efforts will be successful and enjoyable. We share ways to make your yards and patios beautiful while following the University of Florida's Nine Principles of Florida-Friendly Landscaping:
1) Right Plant, Right Place: Plants selected to suit a specific site will require minimal amounts of water, fertilizers and pesticides.
2) Water Efficiently: Irrigate only when your lawn needs water. Efficient watering is the key to a healthy yard and conservation of limited resources.
3) Fertilize Appropriately: Less is often best. Over-use of fertilizers can be hazardous to your yard and the environment.
4) Mulch: Maintain two to three inches of mulch to help retain soil moisture, prevent erosion and suppress weeds.
5) Attract Wildlife: Plants in your yard that provide food, water and shelter can conserve Florida’s diverse wildlife.
6) Manage Yard Pests Responsibly: Unwise use of pesticides can harm people, pets, beneficial organisms and the environment.
7) Recycle: Grass clippings, leaves and yard trimmings composted and recycled on site provide nutrients to the soil and reduce waste disposal.
8) Reduce Storm water Runoff: Water running off your yard can carry pollutants, such as fertilizer, pesticides, soil and debris that can harm water quality. Reduction of this runoff will help prevent pollution.
9) Protect the Waterfront: Waterfront property, whether on a river, stream, pond, bay or beach, is very fragile and should be carefully protected to maintain freshwater and marine ecosystems.
