Aphids and Whiteflies in the garden

by

Each garden and therefore each gardener is faced with pests that plague their plants from time to time. It’s something that we have to learn how to deal with, and when possible learn to control those pesky pests.

Some plants such as honeysuckle, citrus trees and other flowering shrubs and vines are infested each year with aphids and whiteflies. How can you control some of these pests naturally?

Well, whiteflies can be a real challenge. Planting marigolds near or around plants that frequently get infestations of whiteflies might help. Marigolds secrete a substance around their roots that is absorbed by nearby plants and this helps to repel the insects. This might now work for large shrubs and trees though.

Whiteflies have several natural enemies. Get to know the bugs in your garden. Some of them are beneficial. Insects such as lacewings, big-eyed bugs, minute pirate bugs and a tiny wasp called Encarsia are natural predators of whiteflies. Avoid using pesticides in the area as that will kill off these beneficial bugs that otherwise would find and attack the whiteflies.

Aphids are a big problem in my garden each year. They love my honeysuckle – particularly my Harlequin Honeysuckle for some reason. They also thrive on the newly developing leaves and flower buds of my roses.

When an aphid infestation is really bad I get one of my spray bottles and add a couple of drops of dish washing liquid to the water in the bottle. I then go out and spray the affected areas of each plant with this mixture. By selectively spraying the affected areas of the plants I don’t bother the many other insects that are in my garden- many of which are beneficial. I find that for really bad infestations I have to spray the affected plants with this soapy mixture two or three times in one week. After that the aphids are usually gone.

Like the whitefly, aphids have many natural enemies as well. One of the most important enemies of the aphid are the various species of parasitic wasp that lay their eggs inside aphids. Other predators that feed on aphids are lady bugs or the lady beetle as it’s known in some parts, lacewing and syrphid fly.

There are a number of mail order companies, and some nurseries, that sell a huge variety of beneficial insects for the garden. You might think about purchasing some of these insects to help control your whitefly or aphid problems.

I’ve purchased ladybugs in the past. 2000 I believe! I tried to put them on the plants that I knew the aphids and other pests enjoyed bothering. The lady bugs stayed in my garden for the most part for a day or two but then dispersed throughout the neighborhood. I do think that at the time they stayed long enough to control my pest problem.

If anyone has any other suggestions for controlling whiteflies or aphids in the garden I’d love to hear your suggestions. Please leave a comment.






Helpful gardening tips

by

Here’s a a few handy gardening tips that you might find useful, particularly if you are new to gardening:

1. Do your homework. Visit public gardens, read magazines and books.

2. Amend the soil for success. Lighten clay loam soil with compost.

3. Design for surprise: place some curves in your design or interesting nooks that visitors to your garden have to enter to see what magically beautiful plant you have growing there.

4. If you inherit a garden: Wait a season to see what comes up. You may destroy something you want to save. We were lucky to have purchased our house in June. I was able to watch what grew that year and used the following winter to plan out my new garden.

5. Smart plant picks. Purchase plants that are drought tolerant or said to be easy to care for if you don’t want to spend too much time in the garden watering and pruning.

6. Mass appeal. Plant large areas with one flower in one color, such as purple phlox. You can always tell who’s a beginning gardener because they plant one of each plant. masses of three to five or more plants planted together in the garden bed make a much more satisfying display.

7. A wild prairie garden can be work until it gets established. If you want a natural looking garden find out what plants are native to your area and use them abundantly.

8. Japanese-style garden do’s. For dimension, build hills and cover them with moss.

9. Time-saving trick. Plant hosta around the base of trees and you won’t have to trim around them.

10. Get the kids to help. Most kids like helping in the garden. You may still end up doing more work than they do, but it’s a way to spend some quality time with them and also a way to get them outside.

11. Sure-fire critter repeller – build a fence with a gate if you want to keep out skunks, who don’t climb but can dig just fine) and other pets that might frequent your garden. Gates and fences don’t stop all critters but a fence might deter a few of them.

Why do we garden?

by

I think there are many reasons why some of us choose to garden and I’d love to hear what you can add to my list, and your reasons for adding them.

I began my small garden with the hopes of growing vegetables and fruits in my yard. Not only to cut down some of the cost of purchasing food for ourselves, but also to provide my family with the freshest and most nutritious food items that I could. There is nothing like eating a freshly picked tomato is there?

Another reason why I like to grow some of my own food is that I know exactly what it’s been exposed to. Nothing.

I don’t use chemicals on my garden, and because my fruit and vegetables are picked and eaten fairly quickly under very sanitary conditions I know that, unlike some of the fruit and veggies that are sold in the grocery stores (spinach and strawberries for example) that my produce is free from food borne contaminants such as e-coli.

Another reason to garden is that it’s good exercise. Particularly for the obsessed like myself. When I get out in my garden, and I’m in the mood to work, I can be out there for 8 or more hours at a time. I come inside and I’ve earned the right to be tired. I sleep better. I feel a little bit healthier and my muscles get a work out too.

Moderate gardening for one hour can burn 300 to 400 calories!

Exercise is good for the bones too, so therefore gardening helps reduce osteoporosis.

Another reason I enjoy gardening- besides having so many lovely flowers and plants to enjoy eating and or looking at, is that my garden relaxes me. The act of gardening is good for my soul. It puts me at peace with the world even after the most stressful of days.

Gardening also gives me another area to entertain friends and family too. What better place to gather for a nice meal and some good wine with friends than in a lovely garden. Now that’s living.
