Vegetable garden planting is still going strong. Tomato, pepper, and all types of squash plants can be put in now. Tomatoes and peppers actually prefer the warmth of May and will flourish once acclimated to their surroundings. Quick-germinating seed such as zucchini, yellow squash, and string beans can still be planted.
If you have not yet planted cool-weather crops such as spinach, lettuce, broccoli, etc., it is best to wait until September when the weather cools.
Feed your young plants with a slow-release, granular food and supplement with a liquid such as fish emulsion.
