Marglobe Supreme Tomato Guide
Introduced in 1925, this heirloom cross between the Marvel tomato and Globe tomato produces heavenly high yields. Where the creators lacked skill in naming plants, they made up for it in fantastic fruit production.
Marglobe Supreme tomatoes grow best in warmer weather between 65°F-90°F. They do great in containers and small gardens. Bank on Seeds recommends transplanting.
If Direct Seeding
- Direct seed outside 2-3 weeks after last frost date; or
- Direct seed into a container 12-14 inches deep and wide anytime of the year. It can be placed outside when the temperature is between 65°F-90°F; or
Begin the growing season early and start the tomato seeds indoors in trays or pods 4-6 weeks before the last frost date. Germination is best and fastest between 70°F-80°F. It can be transplanted outside 8 weeks later.
Sow 2-3 seeds ¼ inch deep and 24-36 inches apart with rows spaced 36 inches apart. Germination will take 5-14 days. Thin to one strong seedling if all seeds emerge to make sure there is no competition for space or nutrients.
Marglobe tomatoes like well-drained soil rich in organic matter. They also love full sun and warm weather. Water regularly and thoroughly to keep the soil evenly moist. Do not let dry fully between watering - check the top 2-3 inches of soil and if it’s dry, then water it. Avoid watering from overhead or keeping roots soggy as this may lead to blossom-end rot.
Apply mulch to the top of the soil to retain moisture and deter weeds. Use aged compost, 5-10-10 fertilizer, or 18-18-21 tomato fertilizer every 4-6 weeks.
Marglobe tomatoes are full grown in in 75 days. Pick them when they are firm one by one or even better by the vine (keeps longer). Once established snip off leaves and small branches from the bottom 10 inches of the plant to reduce diseases and pests.
Blossom end rot – sprinkle lime in the bottom of the container or around the perimeter of the garden
*Companion plant tomatoes with basil, chives, carrots, nasturtiums, marigolds, borage, squash, asparagus, and parsley. Avoid planting with the brassica family vegetables, corn, and kohlrabi. *
