Gardenia gripe

February 22, 2013

I have a row of gardenias planted across the front of my house – Ed Campbell grafted gardenias to be exact.  They’re doing pretty well, but a couple of times a year I have to treat the bushes for thrips.  The tell-tale signs are leaves that lose their luster and have little, black spots on the undersides of the leaves.  When the plants have been under attack for awhile they seem to develop a black soot on the leaves.

I typically treat for pests in the most organic way possible, but all those methods repeatedly failed on my gardenias and I was at my wit’s end.  The guy from whom I bought the gardenias came by to deliver a few more plants so when he arrived, I showed him my problem.  His solution is to use Bayer Rose & Flower Care which seems to be the only thing that works on this problem.  It’s a combination of systemic pesticide and food for nutrition which should strengthen the plant against further attacks.   Not organic, and sometimes compromises need to be made, but problem solved.

Nutrient Deficiencies

May 26, 2012

How’s your garden doing?  I’ve got some deficiency issues on some of my plants so it’s time to address my care and feeding. Here are some symptoms of plant deficiencies to be aware of. Fertilizing doesn’t have to be complicated, but it is nice to know when it’s a good idea to tweak your plant feeding more specifically when problems do arise.

Nitrogen: Leaves are pale green, plant growth is stunted. Leaves are smallish, stems are thin.

Phosphorus: Stunted growth, thin shoots. Root are stunted, and flowering or fruit development is poor.

Potassium: Leaf tips and edges turn yellow, eventually looking scorched. Fruit is inferior in taste and color.

Calcium: Plants are weakened, with buds and young leaves dying back. Young leaves can turn yellow.

Magnesium: Leaves turn yellow between the leaf veins. Leaves might drop abnormally, growth is stunted.

Sulfur: Young growth is pale green or yellow. Poor growth.

Boron: Young leaves are twisted and thickened. Buds die off, leaves might develop yellow spots.

Copper: Shoots die back. Plants can be pale and yellow. Leaves might now grow.

Iron: Leaves are pale or yellow between leaf veins. Growth is stunted.

Don’t over think it, but use this info as a guide. Most importantly, feed your garden – just do it!

I need to go shopping for fertilizer so I thought we could all use a review.   Here’s a Fertilizing Basics Guide from Anderson’s La Costa Nursery & Garden Design Center in Encinitas.

Some basic info to aid in selecting fertilizers:

All Purpose Fertilizer (4-4-4):
4-4-4 means 4% Nitrogen, 4% Potassium, 4% Phosphorous (by weight). All fertilizers will have many other nutritional elements in its ingredients. A gentle fertilizer blended with a balanced ratio of nitrogen, phosphorus, and potassium. Formulated to provide plants with both a quick start and long-term benefits. Feed every 2 months. Recommended for vegetable gardens, annual and perennial flower gardens, ornamental plantings and all types of container gardening.

Azalea, Camellia and Rhododendron Food (5-5-3):
A special plant food formulated for use on acid-loving plants. A balanced ratio of nitrogen and phosphorus to support vital early season growth and to encourage seasonal flowering. For best results fertilize when growth starts in springtime and immediately after blooming. Feed once more in midsummer. Recommended as a plant food for rhododendrons, azaleas, camellias, hydrangea, blueberries, evergreens, strawberries, and other acid-loving plants.

Transplant/Starter Plant Food (2-4-2):
A great transplanting fertilizer for annual flowers, vegetables, and perennials during initial settling in. A non-burning formula blended from all-natural ingredients to help  plants get off to a vigorous start. Contains bone meal (rich in phosphorus) to enhance root growth. Blended with alfalfa meal which provides naturally occurring growth stimulants to enhance the growth of your plants. Use at planting time and switch to regular Flower food during the growing season.

Organic Citrus and Avocado Food (7-4-2)
A high nitrogen formula for the unique growing requirements of citrus, avocados, berries, and grapes. An effective all natural blend developed both for in-ground plantings and for plants in containers. Contains blood meal and dried poultry waste for fast-acting response. Fertilize crops twice a year – once at planting time or in early spring and again in late May.

Organic Palm & Hibiscus Food (6-5-3):
Give palms a head start with beneficial bacteria and fungi. With a balanced fertilizer formula developed for the unique growing requirements of palms and hibiscus. An effective organic blend developed for both container and in-ground plantings.

Organic Rose & Flower Food (4-6-2):
Mycorrhizae (beneficial bacteria and fungi) gives newly-planted roses a head start for faster establishment. Loaded with alfalfa meal – the ideal rose supplement. A unique plant food with fast-acting nitrogen for early season plant growth and added phosphorus to enhance blossom and root development.

Bon Appetit!

La Dame aux tomates….

April 17, 2012

I had the privilege of hearing Point Loma Garden Club’s Tomato Lady, Karen Greenwald, speak a few weeks back and I’ve been meaning to post the great information she shared with the Bridge & Bay garden club.   Karen is also a fellow San Diego Master Gardener.  Tons of great info.   So here goes:

Planting:

Seeds need to be started 8-9 weeks before you plant outside. Wait until April to plant at earliest to plant your seedlings, acclimating for a week before you plant. Dig the hole, drop in some fertilizer water the hole, then let it drain. To plant your seedlings, remove the branches except the last three at the top. Also, pinch off any flowers to direct the plant’s energy to grow. Scrinch (Karen’s word!) the roots. Bury your plant to 1/2 inch under the bottom set of leaves, meaning you will be burying most of the stem. This will encourage more roots to form and your plant won’t be spindly. Stake your plant right away. If you wait to stake later, you’ll cause damage to the roots.

Plant 3′ apart in ground. If you are container-gardening tomatoes, use a minimum 15 gallon pot. Any smaller than that is too small. Use putting soil, not dirt from your yard, filling your container 3 inches from top of container. Mulch only with healthy mulch.

Tomatoes require a minimum of 6 hours of sun. The more sun, the better, but they prefer morning sun to afternoon.

Fertilizing:

Karen likes to use Tomatoes Alive fertilizer. follow directions, don’t overdo it! First feeding is when you plant, then you’ll feed two more times – when it flowers and it fruits. Don’t over feed!

Watering:

Don’t over water. Water stressed plants taste better. Dont judge by midday droop. Look at plant first thing in the morning. If it’s limp, water only in morning. Dont sprinkle, water deeply. If you mulch, you should ony have to water once every two weeks, deeply. If you are container-gardening, of course, you’ll need to water more often than that, but again, don’t over water.

Miscellaneous:

Determinate or Indeterminate – does it really matter? But there are reasons to choose one over the other. Determinate tomatoes set fruit at the same time in a shorter growing season. Indeterminate tomatoes will grow a lot longer, are more productive, need to be staked.

Tomatoes and basil are good companions. If you buy a six-pack of basil, it will yield 60 plants because you can split each cell up to many little plants.

Marigolds planted around tomatoes thwart nematodes and white fly.

Tomatoes hate corn, potatoes or broccoli, so don’t plant those nearby.

I have followed Karen’s philosophy about having birds in the garden to keep pest populations under control. Keep the birds coming with bird feeders, but hold back from keeping the feeders full all the time to encourage bird foraging. The hope is that they’ll explore your plants for snacks, aka pests.

Karen is a big saver of seeds from tomatoes she loves. Paper towels are perfect seed savers. Write the name of the tomato you are saving on the paper towel, wipe seeds on the surface, throw in shoebox and keep in a cool, dry place until you are ready to plant next year.

Tomatoes don’t have to be rotated around your garden. Tomatoes are perennials. If your plant makes it through winter you might see sprouts coming up around the base. If you get this lucky, just cut the old stem back, and hope for the best!

Bon Appetit!

Tomatoes!

Oh, YUM! I can't wait!!!

I’ve been an avid composter of coffee grounds for a long time.  I like my coffee, it adds bulk to my compost pile, it smells good, and I have satisfaction of knowing that coffee grounds are a perfect amendment for acid-loving plants.  Except they’re not….  Whaaatttt??!

For a long time, I have been under the belief that coffee grounds are the perfect amendment for acid-loving plants.  Only last week did I have cause to change my thinking.   I made a comment on Life On The Balcony’s Facebook page about my blueberries getting a regular dose of coffee grounds for the acid, and the reply back was that although they are a good source of nitrogen, the acid content of coffee grounds has been discredited.  That was news to me so I hit the internet for some study time.  Although I did find more than a few references that followed my antiquated thinking, I also found quite a few good references stating that grounds are actually pH neutral.  So, time to rethink the whole coffee grounds mantra!

Here are a few articles to peruse:

Using Coffee Grounds Correctly

Coffee Grounds and Composting

Coffee Grounds – Myth, Miracle or Marketing?

Coffee Grounds Perk Up Compost

11 Great Reasons To Reuse Coffee Grounds

So, there you have it.  I’d like to thank Fern at Life on the Balcony for correcting me.  Always nice to learn something new from a fellow Master Gardener.  Thanks, Fern!!!

Beautiful gardenias in my garden, apparently not improved by coffee grounds!

Under Cover

October 20, 2011

One of the nice things about being a Master Gardener is that we get to hear top-notch and interesting speakers at our monthly meetings.   At the September Master Gardener meeting, our guest speaker, who also happens to be a Master Gardener, talked to us about cover crops.

I have never paid a lot of attention to cover crops because I’m a raised-bed gardener and really didn’t think cover crops applied to me in my small spaces.  Well, I’m rethinking after hearing this talk.

This concept has been around as long as people have been farming.  In first century Rome, it was known that lupines sown in September didn’t grow well, but their value was that they amended the soil like a good manure.  I wonder how they figured this out!!!

In addition to composting, fertilizing, and mulching, cover crops are one more way to build up your soil. The main goal is to improve soil fertility. Cover crops used in this way are also known as Green Manure.   Secondary goals are to improve soil quality, prevent erosion and even weed management by providing organic matter.

Nitrogen is generally lacking in soil so certain cover crops such as legume crops can add nitrogen and actually collect nitrogen in nodules on their roots which then goes into the soil.  Other cover crops like cereal grains catch surplus nitrogen which is released back into the soil when the crop is tilled under.

Although it’s easier said than done, don’t get overwhelmed by all the choices you can make with cover crops.  Just do it.  If you really get into the process then you can decided to do a cool season crop, a warm season crop, an inoculant crop, raw or rhizocoated seeds,  legume or non-legume, or Endophyte Enhanced crops.  Whew!

The guest speaker said she likes to use a mix of vetch and oats which she broadcasts, and bell beans which she plants 6″ apart in rows that are 18″ apart.  She orders her mix from Peaceful Valley (GrowOrganic.com).   I have to admit that when I first looked at the site I was a bit overwhelmed by all the choices, but after I reminded myself that anything I do can only be an improvement, the clouds parted and I ordered 5 packets of the PVFS Organic Soil Builder Mix – Raw Seed.  (Note: if you are a Master Gardener remember to ask for the 10% discount!)

Buckwheat is a warm season cover crop that goes full circle in six weeks.   Buckwheat puts sugar in the soil which helps plants absorb calcium.  It blooms pretty flowers which attract bees.  The general rule is to cut it down when 50% of the plants are blooming.  If you wait longer, you’ll lose nitrogen when the plants start developing seeds.  This is a good rule of thumbs for legumes as well.   Cut down and mulch into your garden bed, then cover with plastic for a few weeks to help with the breakdown.  You can plant immediately upon removal of the plastic. I could have planted buckwheat in August, but it’s too late now, so I’ll make a note for next year.

The Western Fertilizer handbook was recommended by the speaker for additional guidance.  I’ve already ordered a copy!!!

Here’s a great chart to look over for comparing different kinds of seed and how you would use:  Seed Comparison Chart

So, there you have it.

Let Your Plants Work For You

June 9, 2011

When removing spent pea vines, cut them off at the soil level rather than pulling them out. The roots have nodules that contain excess nitrogen which is released into the soil as the roots decompose. I knew this about beans, but it never occurred to me that peas would add nitrogen to the soil, too. [...]

N-P-K

February 16, 2011

When I started really paying attention in the garden and decided to learn more and do a better job, these three letters seemed so intimidating to me. I understood N – Nitrogen. P stands for Phosphorus and K stands for…….Potassium. What?! That’s where I would get hung up. I know it’s the chemical but K [...]
