The Art of

Vegetable Gardening

Vincent J. Mannino,

County Extension Director – Fort Bend

Why Garden?

 Homegrown vegetables taste better.

 You have control over what pesticides are applied.

 Good exercise.

 Fun!

How to be a

Great Gardener

 Proper Soil Preparation and Fertilization

 Select Recommended Varieties

 Plant at the Right Time

 Control Weeds, Diseases and Insects

 Adequate Soil Moisture

 Harvest at the Right Time

 Plan and Prepare

Get a Quality Start! - SEEDS

 Seed sources to use:

– Reputable catalogs

– Reputable local retailers

– Saved from open-pollinated sources

– New varieties

– Heirloom varieties

Getting a Quality Start! - SEEDS

 Saving your own seed:

– Hybrids will not be same as what you purchased

– Disease potential.

– Pick when mature.

– Process properly

– Store properly

*** Keep accurate records each year!

Ideal Garden Location

 Receives 8 + hours of sunlight.

 Soil has good internal and external drainage.

 Free of competition from other large plants, buildings, etc.

 Near a source of water.

 Visible!

What is an Ideal Soil?

 pH 6.0 – 6.5 (Slightly Acid).

 5 – 10% Organic Matter.

 40 – 45% Inorganic Matter (Sand,

Silt or Clay)

 50% Pore Space ( Air and Water).

 Texture - Sandy to Sandy Loam.

Soil Preparation

 Have a soil test run.

 Incorporate plenty of organic matter.

 Add large amounts of bank sand or sharp sand to improve drainage.

 Add nutrients if necessary.

Cultural Practices Reduce

Pesticide Use (IPM)

 Healthy Soils

 Resistant Varieties

 Planting Time

 Proper Watering

 Soil Fertility

 Sanitation

 Weed Control

 Diverse Planting

 Crop Rotation

Growing Up - Not Out

Composting – Recycle Yard Waste

Compost Materials

 Household organics

 Leaves

 Pine Needles

 Hay

 Grass Clippings

 Paper

Starting Your Own Plants from

Seeds  Average last frost ~

March 5

 Select Proper

Varieties.

 Sterile Potting

Media.

 Sterile Containers.

 High Light Intensity for 14-16 hours.

 Regular Applications of Soluble Fertilizer

Container Gardening

 Excellent for small yards or patio homes.

 Requires more care:

 Water.

 Fertilizer.

 Use large containers with a loose potting media to reduce compaction .

Harvest at the Proper Time

 Quality can vary greatly depending on time harvested.

 Take the time to learn when the various vegetables should be harvested.

Recipe for Successful

Production

*

Tomatoes can be temperature sensitive for fruit set

Tomatoes - Plant large, vigorous plants. Incorporate ¼-½ cup of complete, slow release fertilizer at planting.

Tomatoes - May plant as early as

January 15 th in 1-gallon containers and grow in full sun until after the last killing frost.

Apply a weekly foliar spray of a water soluble fertilizer.

Work in 2-3 Tbs. of high nitrogen fertilizer when 1 st cluster of fruit sets.

Fertilize every two weeks with

21-0-0 at 1 Tablespoon per plant.

Common Diseases and Insects of the Nightshade Family

 Harvest When

Pods are Young and Tender.

Lima (Butter) Beans

 Plant March - Early

April and September.

 Moderately Fertile

Soil.

 Harvest When Pods are Mature and Seeds

Fully Developed.

Southern Peas

But High Quality.

Common Diseases and Insects of the Legume Family

Grass Family – Sweet Corn

Plant March – April.

Direct plant seed

Fertilize at Planting,

1 Foot Tall & Tassel

Visible in the Whorl with ½-1 Cup 21-0-0 per 10 Ft. of Row.

90%+ Harvested the same day.

Types of Sweet Corns

 Sweet Corn (su)Traditional sweet corn with sweet flavor & creamy consistency.

Sugar degrades rapidly to starch .

 Sugary Enhanced (se)

– Tender kernels, much sweeter flavor and creamy consistency. Maintains sweet flavor much longer than traditional sweet corn.

Types of Sweet Corns

 Super Sweets (sh2)Very crisp kernels, even after freezing, and a much higher sugar content. Sugar is very stable within the kernel but lacks the creamy consistency.

 Triple Sweets (su x se x sh2)Combination of high sugar and creamy consistency, carrying a combination of traits from both sugar enhanced and super sweet varieties.

Know the Good Guys

Know the Good Guys

Integrated Pest Management

 Provide plants with the best care and culture possible.

 Use only the most adapted varieties.

 If chemical (organic or man-made) control is necessary start with the most environmentally friendly products first.

 Apply chemicals, (organic or man-made) properly, safely and according to the label.

Recommended Pesticides

 Insecticides

 insecticidal soaps malathion carbaryl permethrin

 Fungicides

 pesticidal oils- petroleum based copper base sulfur base captan daconil

 ALWAYS FOLLOW LABEL DIRECTIONS
