How to Grow an Egg Yolk Plant


Tomatoes are one of the most popular plants in a vegetable garden and there are hundreds of varieties for you to choose from. Discovering an unusual variety that your neighbor is not growing gives your garden a unique look. The egg yolk plant is one of those uncommon tomato plants that is worth your while to grow. Round, smaller yellow tomatoes that remind you of egg yolks and have a rich, sweet flavor fill the long vines of this tomato plant.

Starting Seeds

Step 1

Purchase egg yolk tomato plant seeds that are packaged for the current year. Fresh seeds will germinate easier and more successfully than seed from former years. Egg yolk tomatoes as starter plants from your local nursery will be difficult to find, so starting from seeds, which can be found, will be easier.

Step 2

Fill small containers, cups or seed-starter pots with seed-starter soil. Seed-starter soil will contain the nutrients your tomato seeds require to germinate and grow.

Step 3

Plant your egg yolk tomato seeds 1/8 inch deep in the seed-starter soil. Your egg yolk tomato seeds should be planted inside eight to 10 weeks before the last frost for your area. Egg yolk tomatoes are medium-early maturing tomato plants, meaning they will begin bearing fruit in about 65 days after the seeds germinate.

Step 4

Water your planted seeds but do not let the soil become soggy. The seed-starting soil should be kept moist during germination. Once you see your egg yolk plant seeds beginning to germinate and appear, move the seedlings to sunny spot. If your seedlings begin to look leggy it indicates that they are not receiving enough sunlight and you may need to supplement with grow lights.

Planting in the Garden

Step 1

Plant your egg yolk tomato seedlings in your garden when the threat of frost is gone and the seedlings are 5 or 6 inches tall. Before you plant them into the ground you will need to harden them off. This acclimates the seedlings to the outside. To harden off your seedlings, place them outside during the day and bring them back inside at night for one to two weeks.

Step 2

Dig a hole for your egg yolk tomato plant seedling that is large enough to accommodate its roots. Plant your egg yolk plants 24 to 36 inches apart. Place each plant into the hole carefully to avoid damaging the roots, then fill the hole around the plant with soil.

Step 3

Mix an equal balanced (10-10-10, 15-15-15) liquid fertilizer with water, 50-50. Use this to do your first watering of your egg yolk plant after planting the seedlings.

Step 4

Water your egg yolk tomato plants regularly and deeply. A deep soaking that will reach all the roots of your plant is preferred over more frequent, lighter watering.

Step 5

Fertilize your egg yolk tomato plants regularly following the instructions on the package. In the beginning, before your plant begins to blossom, use a fertilizer with a slightly higher nitrogen content. This will encourage growth and strengthen your plant. After your egg yolk tomato begins to produce blossoms, switch to a fertilizer that has a higher phosphorus and potassium content as this will help produce more and better quality fruit on your tomato plant.
