Master Pests, Diseases & Weeds

How to prevent, identify and manage garden pests, plant diseases and weeds.

Join me as I walk you through mastering pests, diseases and weeds in the garden and landscape. These three foes are inevitable for every gardener, but here, I'll show you the proactive steps you can take to minimize their presence and how to identify and manage what does come.

In this course, I cover synthetic and organic principles, but I focus on organic treatments and explain why those natural controls or products can make such a difference - on the success of your garden and for our environment. You don't need a bunch of expensive products. In fact, some of those products can do more harm than good. I'll show you what matters and how to implement these steps in your garden.

When it comes to pests, diseases and weeds; there is a lot of bad information out there. It can be challenging and confusing to know what to do and what not to do. Make no mistake, there's no such thing as a garden that is completely free of pests, diseases or weeds. You will have some of these problems every season.

As a national gardening TV host and recognized expert for nearly two decades, I'll be your guide to to make sense of it all and understand the easy (and often free) steps you need to know. I've got you covered here in the Master Pests, Diseases and Weeds course presented by joe gardener Online Gardening Academy™.

Feedback shared by some of our students:

"This was the most valuable class I've taken for the backyard gardener, including the Master gardener class. You are the BEST out there! I can't say enough great things. I got so much more out of this class than I expected. I'm really looking forward to what's coming. I will not hesitate to take another in the future." - Liz D. - Oregon

"What a great course. I saw damage on my broccoli and because of this course knew right away what to look for and how to try and stop it. So far so good. You provide tools to help with further exploration and reference that has really come in handy. Can’t wait for the next two courses! Thank you!" - John R. - Connecticut

"I felt like I got explanations for the 'whys' and 'hows' that made sense. Gardening the same 'ol way because you've always done it that way or that's just the way you were taught is why it can be so frustrating. But understanding the purpose behind doing things and implementing the right methods for your particular garden is priceless." - Sandi G. - Georgia

"The course was great. It got me to look at what’s happening in my garden much more closely and try some treatment options that I may have been too intimidated to try before. Fantastic job, Joe. I took your Beginning Gardener Fundamentals course and thoroughly enjoyed both." - Adam G. - Wisconsin

"Oh my goodness this is exactly what I needed. I’ve been gardening for 20 years. But only growing vegetables for about six. You have helped me so much. I have taken gardening class and landscaping classes, but your courses were more helpful to me. I spent more money taking classes at the College, and didn’t get as much information in a whole semester as what you gave to us in these modules." - Rachel T., California

"The phrase "Joe Gardener" does this, "Joe Gardener" does that has been repeated many, many times this year as I share the information that I've learned from these courses. Can't get enough of your courses!" - Mary T., Virginia

"You listed solution options with pros and cons to help me make informed decisions - Excellent. The online module format works perfect for my busy schedule. And I love that I can access the modules again for reference whenever I want - Excellent." - April S. - Oregon
