Growing Tomatillos & Ground Cherries

Care of Plants On Arrival

Your plants have just spent up to 3 days without light or water and may have yellow leaves or show evidence of wilting. Through years of shipping experience, we have found that more than 98% of these plants will survive and thrive if you follow the simple care instructions below.

Please take your plants out of the shipping box as soon after their arrival as possible, taking care not to damage any stems or leaves as you free the plants from the cardboard packaging.

If the soil is dry, water gently but thoroughly from above or set the pot in a saucer of water for an hour or so -- just long enough for the soil in the pot to become thoroughly moist, but not soggy.

Place your plants in bright but indirect light indoors or, if temperatures permit, outdoors in the shade, sheltered from the wind. Don't put your plants in full sun right away because their leaves are tender after the trip and could be burned (sunscalded) or fall off if exposed to too much sun too soon. Allow your plants to adjust gradually over the next few days to increasing amounts of sunlight.

We've tried to time the shipping of our young plants so that they arrive at or near the frost-free date in your climate zone. If, however, the weather is still raw and a frost seems likely, transplant your plants into larger pots, taking them outside during the day when the weather is mild and bringing them in whenever frost or blustery cold weather threatens. Young plants are more tender than mature plants, and even if the last spring frost is already past, near-freezing temperatures and cold spring winds are capable of killing your new plants. Expose your young plants to outdoor conditions gradually, giving them a chance to harden off before they're planted out. When the weather does settle and both days and nights become reliably mild (night-time temperatures should remain above 50°F), then it's time for planting out.

Planting Out

When the weather is warm and settled, choose a planting location in full sun with rich, fertile soil and good drainage. Keep in mind when choosing a location that tomatillo plants are quite vigorous and will spread horizontally unless you decide to stake, cage, or trellis them. To reduce soil-borne diseases among vegetables that belong to the same family, plant tomatoes, tomatillos, eggplants, and peppers where you haven't grown them or potatoes in the past 3 years (they are all members of the nightshade family). Dig a hole that will generously accommodate the plant's root ball, and mix compost or aged manure and a handful of low-nitrogen, organic fertilizer into the planting hole. If the weather is hot and sunny, plant in the cool of morning or wait until late afternoon to minimize stress. Recommended spacing between plants is indicated on the White Flower Farm label.

To remove a plant from its pot, flip the pot over, tap on its bottom, and slip the plant out. Do not pull the plant out by its stem. Loosen the root ball and tease the roots apart if they are matted or tangled. Set vegetable starts into their holes so that the tops of the root balls are level with or just slightly below the surrounding soil.

Push soil back into each planting hole and firm the soil around each plant to eliminate air pockets. Water thoroughly to further settle the soil. Keep the soil around the plants moist but not soggy and provide shade (with row cover, cardboard, or lath) for the first few days. Transplant shock is not uncommon, but within a week or less the plants' roots will regain their ability to provide moisture to the foliage. Remove shading once plants perk up.

Continuing Care

If rain is scarce, water your vegetable plants deeply and regularly (weekly, or more often in hot, dry weather).

Side-dress with compost or fertilizer 2-3 weeks after transplanting, using a lower nitrogen formula. Fertilize again when plants begin to bloom.

Pick tomatillos and ground cherries when the papery husks have filled out and the fruit inside is pale green (or purple for our colored variety).
